Introduction
Syphilis is a systemic bacterial infection caused by the spirochete
Treponema pallidum
. Head and neck mucosal manifestations of syphilis can be observed in each and all of primary, secondary and tertiary syphilis, especially in the secondary one. Therefore, oropharynx is an unusual localization of syphilitic lesions, mainly represented by ulcerous lesions, tissue hypertrophy, mucosal patches and cancer-like lesions. Serology is routinely considered the gold standard for the screening and diagnosis of syphilis. However, direct detection is routinely used during polymerase chain reaction (PCR) of oropharyngeal tissue and suspicious cervical lymphadenopathies.
Methods
PRISMA 2020 guidelines were applied to make a systematic literature review with the aim to make an overview of clinical manifestations and diagnostic tools of oropharyngeal syphilitic infection. A computerized MEDLINE search was performed using the PubMed, Web of Science and Cochrane databases.
Results
The intended analysis was based on 38 papers, including a total of 55 cases. The main localization of oropharyngeal infection was the tonsil (71%), followed by lateral and posterior wall of oropharynx (16%). Ulcerous lesions were the most frequently encountered lesions in the primary syphilis (56%) and secondary syphilis (36%), whereas gumma’s lesions were encountered in the tertiary syphilis (57%). Diagnosis based on serological assays was used in combination with non-treponemal methods to determine disease activity (80% cases).
Conclusions
Oropharyngeal syphilis has historically been referred to as the “great imitator” due to its highly variable manifestations, which can resemble malignancies. Physicians have to recognize oropharyngeal luetic features early, in order to set up an effective diagnostic and therapeutic work-up.

Objectives and background: Oral squamous cell carcinoma (OSCC) is a highly malignant disease with an increasing incidence. The need to improve therapeutic strategies for patients affected by OSCC is an urgent challenge. Currently, the advent of immunotherapy represents an important step toward this aim. Programmed cell death‐ligand 1 (PD‐L1), a membrane protein that can be expressed on tumor and inflammatory cells is a key biomarker whose expression is determined by means of immunohistochemistry and is necessary for selecting patients for immunotherapy. Methods: In this study, we review the methods of PD‐L1 assessment and outcomes achieved with immunotherapy in the treatment of OSCC patients. Results: Based on a meta‐analysis we demonstrate a lack of prognostic significance of PD‐L1 in OSCC. Conclusions: We also highlight unresolved issues including difficulties in standardizing PD‐L1 evaluation and discuss future opportunities such as leveraging digital pathology.

PurposeThe aim of this study is to evaluate the prognostic value of pre-treatment advanced lung cancer inflammation index (ALI) in patients with HPV-negative HNSCC undergoing up-front surgical treatment.MethodsThe present multi-centre, retrospective study was performed in a consecutive cohort of patients who underwent upfront surgery with or without adjuvant (chemo)-radiotherapy for head and neck squamous cell carcinoma (HNSCC). Patients were stratified by ALI, and survival outcomes were compared between groups. In addition, the prognostic value of ALI was compared with two other indices, the prognostic nutritional index (PNI) and systemic inflammatory index (SIM).ResultsTwo hundred twenty-three patients met the inclusion criteria (151 male and 72 female). Overall and progression-free survival were significantly predicted by ALI < 20.4 (HR 3.23, CI 1.51–6.90 for PFS and HR 3.41, CI 1.47–7.91 for OS). Similarly, PNI < 40.5 (HR = 2.43, 95% CI: 1.31–4.51 for PFS and HR = 2.40, 95% CI: 1.19–4.82 for OS) and SIM > 2.5 (HR = 2.51, 95% CI: 1.23–5.10 for PFS and HR = 2.60, 95% CI: 1.19–5.67 for OS) were found to be significant predictors. Among the three indices, ALI < 20.4 identified the patients with the worst 5-year outcomes. Moreover, patients with a combination of low PNI and low ALI resulted to be a better predictor of progression (HR = 5.26, 95% CI: 2.01–13.73) and death (HR = 5.68, 95% CI: 1.92–16.79) than low ALI and low PNI considered alone.ConclusionsOur results support the use of pre-treatment ALI, an easily measurable inflammatory/nutritional index, in daily clinical practice to improve prognostic stratification in surgically treated HPV-negative HNSCC.

Background
Although isolated fractures of the ulnar shaft are considered common and relatively benign injuries, numerous complications can arise especially in the context of suboptimal care pathways. For pediatric patients, however, there is no single indication of the surgical approach. In the context of the management of these complications, it is known that the vascularized fibular graft has numerous advantages and indications in the treatment of recurrent pseudarthrosis. However, in revision surgery the frequent occurrence of anatomical subversions requires the use of fixation means adapted to the individual patient. We present a clinical case of an adult patient suffering from post-traumatic ulnar pseudarthrosis treated with autologous vascularized fibula grafts and 3D-planned custom-made plate.
Case presentation
A 38-year-old Ivorian woman came to our attention with a painful nonunion of the ulnar shaft and significant dysmorphism of the left forearm, with shortening and flexion of the limb as an outcome of unspecified road trauma in childhood. No alterations of the nerve compartment were reported. As far as detectable, she had undergone autologous bone grafting and implantation of questionable synthetic means, without acute treatment. Since we evaluated the patient (2012), we have performed two debridement surgeries, associated with autologous avascular bone graft from the iliac crest and plate fixation (2012 and 2014). In both cases, rupture of the fixation media was observed. In 2021, the pseudarthrosis was treated with a vascularized fibular bone graft. The subverted radius and ulna anatomy and poor bone quality required patient-specific reconstruction of the pseudarthrosic ulna from a 3D scan and the production of custom-made plate and screws, supported by the creation of special guides for drilling and by optimizing the positioning of screws with preoperative digital models. In the postoperative period, regular follow-up visits with X-rays evaluations were performed at 1, 3 and 6 months after surgery. No inflammatory reactions or local rejection were found. The fibula graft healed at the proximal ulnar junction six months after the operation while it took eight months to heal at the distal junction. Functionally, we observed a pain reduction and a range-of-motion preservation.
Conclusions
The multiple failures of diaphyseal reconstruction with avascular bone grafts have forced the indication to the vascularized fibular flap. This case is a unique experience but we believe that the association between vascularized bone graft and the potential for customization through 3D planning represents a valid surgical potentiality in complex cases of post-traumatic reconstruction.

Background
Inflammatory blood markers have been associated with oncological outcomes in several cancers, but evidence for head and neck squamous cell carcinoma (HNSCC) is scanty. Therefore, this study aims at investigating the association between five different inflammatory blood markers and several oncological outcomes.
Methods
This multi-centre retrospective analysis included 925 consecutive patients with primary HPV-negative HNSCC (median age: 68 years) diagnosed between April 2004 and June 2018, whose pre-treatment blood parameters were available. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), systemic inflammatory marker (SIM), and systemic immune-inflammation index (SII) were calculated; their associations with local, regional, and distant failure, disease-free survival (DFS), and overall survival (OS) was calculated.
Results
The median follow-up was 53 months. All five indexes were significantly associated with OS; the highest accuracy in predicting patients’ survival was found for SIM (10-year OS = 53.2% for SIM < 1.40 and 40.9% for SIM ≥ 2.46; c-index = 0.569) and LMR (10-year OS = 60.4% for LMR ≥ 3.76 and 40.5% for LMR < 2.92; c-index = 0.568). While LMR showed the strongest association with local failure (HR = 2.16; 95% CI:1.22–3.84), PLR showed the strongest association with regional (HR = 1.98; 95% CI:1.24–3.15) and distant failure (HR = 1.67; 95% CI:1.08–2.58).
Conclusion
Different inflammatory blood markers may be useful to identify patients at risk of local, regional, or distant recurrences who may benefit from treatment intensification or intensive surveillance programs.

Objectives: The application of fasciocutaneous free flaps for reconstruction of head and neck defects following oncological surgery has increased since the 1970s, coinciding with developments in microvascular techniques. Although reported success rates are between 90% and 99%, flap failure continues to occur, most frequently due to venous congestion. This study examines the rates of re-exploration and flap failure according to the number of venous anastomoses in patients receiving free flap reconstruction after head and neck cancer surgery. Materials and Methods: This retrospective analysis included 163 patients who underwent head and neck reconstruction with free flaps (radial forearm free flap [RFFF] and anterolateral thigh flap [ALTF]) at the University Hospital of Verona between January 2019 and June 2024. Variables examined comprised the type of flap performed, donor and recipient vessels utilized, and number of venous anastomoses, as well as the type (end-to-end [ETE] versus end-to-side [ETS]) and site (internal jugular vein versus external jugular vein) of venous anastomosis. Results: The overall success rate was 93.3%, with no significant difference between single and dual venous anastomosis groups. Prompt re-exploration upon detecting signs of flap failure is critical, as approximately one-third of such failures may be prevented through timely intervention. Conclusions: Single venous end-to-end anastomosis utilizing the internal jugular vein system is typically effective. Further research is warranted to clarify the indications for dual anastomosis involving the external jugular vein system.

Objective: This article evaluates the reconstructive potential and functional outcomes, as well as the risks and potential perioperative complications of using free flaps in patients with advanced-stage malignant laryngeal neoplasms who require salvage surgery and reconstruction. Additionally, it assesses the effectiveness of various flap harvesting and in-setting techniques, including the performance of microvascular anastomoses. Materials and Methods: This retrospective study included 13 male patients (age range 47–76 years) diagnosed with laryngeal neoplasms, who were referred to the Department of Otolaryngology at the University of Verona between 2017 and 2022. All patients underwent salvage total laryngectomy followed by concurrent reconstructive surgery utilizing microvascular flaps. Recovery of function (phonation) and incidence of complications were evaluated in a follow-up of at least three years. Results: Only one patient experienced necrotic failure of the microvascular free flap, probably due to post-op complications. The patient required revision on the 10th day after surgery and was reconstructed using a pedicled pectoralis major muscle flap. Two patients developed a pharyngocutaneous fistula. Other three patients had pharyngoesophageal stenosis, two experienced recurrence, and one patient passed away due to septic shock. All patients achieved satisfactory functional outcomes regarding vocalization, while complete oral intake was restored in eight patients. Conclusions: Considering the limited sample size, the findings suggest that microvascular flaps represent a feasible option for reconstructing advanced laryngeal tumors, though complication rate may still be considerable. Tailoring reconstructive approaches to individual patients may enhance surgical outcomes.

Head and neck cancers (HNCs) arise from anatomically adjacent sites and subsites, with varying etiological factors, diagnostic strategies, prognoses, and treatment approaches. While conventional squamous cell carcinoma (SCC) is the most common histology in the head and neck district, HNCs encompass a variety of rare histopathological entities, categorized into epithelial tumors such as salivary gland cancers, sinonasal tumors, neuroendocrine tumors, malignant odontogenic tumors, and SCC variants versus non-epithelial tumors including soft tissue sarcomas, mucosal melanomas, and hematological malignancies. Rare HNCs (R-HNCs) represent a diagnostic and clinical challenge, requiring histopathological expertise, the availability of peculiar molecular analysis, and the personalization of local and systemic treatments, all guided by a multidisciplinary tumor board. Here, we provide a comprehensive literature review on R-HNCs, emphasizing key histopathological and molecular characteristics that are crucial for guiding treatment decisions. An insight about the latest developments in systemic treatments is also reported.

Background
The retropharyngeal space is a deep compartment of the head and neck region which extends from the base of the skull to the mediastinum, between the posterior pharyngeal wall and vertebral muscles, delimited laterally by carotid sheaths. Pathological processes of the retropharyngeal space are rarely encountered, generally are isolated and painless masses often cystic, and they usually originate from branchial arch anomalies, but only in rare cases, they turn out to be foregut duplication cysts. Foregut duplication cyst is rare congenital malformations arising along primitively derived alimentary tract during the first trimester in the developing embryo, mostly seen in the thorax and abdomen, with just few cases reported in the head and neck region. We report an extremely rare case of a foregut duplication cyst lined with respiratory epithelium located in the retropharyngeal space, at the level of the oropharynx, of an adult patient with dysphagia surgically treated, and we also made an analysis of the published literature about this very uncommon condition.
Case presentation
A 63-year-old male patient with chronic dysphagia was diagnosed with a retropharyngeal cystic lesion, which was surgically treated. Final pathologic evaluation confirmed the diagnosis of a rare foregut duplication cyst lined with respiratory epithelium. A review of the pertaining published literature about the head and neck foregut duplication cysts was made, with a particular emphasis on retropharyngeal ones.
Conclusions
Retropharyngeal foregut duplication cysts are a very rare congenital cyst of the head and neck. Clinical symptoms such as dysphagia and dyspnea should be evaluated with fibrolaryngoscopy, and CT and MRI scans are of great significance for definitive diagnosis, which should include the possibility of a foregut duplication cyst in the differential diagnosis. Surgical excision is the elective treatment for this lesion, in order to prevent complications including infection and compression symptoms or eventually malignant transformation.

Introduction
Nowadays, 70% of patients in Europe and the USA are affected by a p16 + , potentially HPV driven oropharyngeal squamous cell carcinoma. However, despite the improved survival rate in this group, the quality-of-life remains low in cases which neck dissection took place. In this vein, in recent years, some surgeons have considered to avoid dissection of level IIB, proposing a supra-selective non-IIb neck dissection.
Materials and methods
A retrospective, longitudinal, multicentric study was conducted, including patients with pathologically confirmed primary HPV + or HPV − OPSCC who went through surgical treatment for the primary lesion and neck dissection.
Results
141 patients were included. Among them, 99 (70.2%) were male and 42 (29.8%) were female. The mean age was 62 ± 9 years (range 36–81). The most frequent anatomical location was the tonsil in 63 (44.7%) of patients. The most common approach was the classic transoral oropharyngectomy in 51 (36.2%) patients. Immunohistochemistry for p16 was positive in 62 (44%) patients. One-hundred and five (74.5%) patients received a unilateral ND, and a 36 (25.5%) a bilateral ND. Of those, a 12.8% (18/141) of patients were level IIb LN + . According to our results, level IIb ND should be considered in patients underwent therapeutic ND with positive LN metastasis in level IIa (OR = 9.83; 95% CI 3.463–27.917) or III (OR = 6.25; 95% CI 2.158–18.143), advanced (T3/T4) oropharyngeal primary tumors (OR = 3.38; 95% CI 1.366–8.405), and patients with ENE (OR = 6.56; 95% CI 2.182–19.770), regardless of p16 status.
Conclusions
According to our results, level IIb ND should be considered in patients who underwent therapeutic ND with positive LN metastasis in level IIa or III, advanced oropharyngeal primary tumors, and patients with ENE, independently of p16 status. Prospective data are necessary to definitively ensure the safety of omitting ipsilateral or contralateral level IIb ND in cN − patients with early stage disease.
