Background The clinical management of nonmalignant breast papillary lesions diagnosed at core-needle biopsy (CNB) is controversial. A meta-analysis was performed to evaluate pooled estimates of the underestimation of malignant papillary lesions (which were diagnosed as nonmalignant lesions at CNB) and to survey factors that affect that underestimation. Methods We searched for studies that provided data on CNB underestimates of malignant breast papillary lesions indexed in PUBMED. The pooled estimate for underestimation was calculated. The association between each variable and underestimation was investigated using either random- or fixed-effects logistic modeling. Results A total of 34 studies, which included 2,236 nonmalignant breast papillary lesions diagnosed at CNB and histologically examined after surgical excision, were included. Of these, 346 nonmalignant lesions at CNB were upgraded to malignant after surgical excision. The pooled estimate for the percentage of underestimation was 15.7 % [95 % confidence interval (CI): 12.8–18.5 %]. The factors associated with higher underestimation included atypical papillary lesions ( P  < 0.001), positive mammographic findings ( P  = 0.022), and article publication year before 2005 ( P  < 0.05). Conclusions It is recommended that atypical papillary lesions at CNB undergo surgical excision, and it is reasonable to follow patients with benign lesions with serial imaging. Lesion type, mammographic findings, and article publication year were significantly associated with underestimation.

An early adolescent girl was referred to our breast surgery clinic with multiple right-sided breast masses and several months of unilateral bloody nipple discharge. MRI demonstrated multiple enhancing masses in the right breast with intrinsic hypertensive T1 signal of the ducts extending to the nipple. A biopsy showed partially sclerosed intraductal papillomas without atypia or malignancy. Following extensive counselling with the patient and her family, two palpable breast masses and a single central breast duct responsible for bloody nipple discharge were fully excised. Histopathological analysis showed unique overlapping features of resembling intraductal papilloma, nipple adenoma and fibroadenomas. The patient has had resolution of her bloody nipple discharge and excellent cosmetic outcomes post-surgery. Intraductal papilloma is rare in the adolescent population and the risk of concurrent and future malignancy is not well established. Thus, a tailored approach to the work-up and management of paediatric breast masses is essential.

Background Management of pure intraductal papillomas (IDP) without atypia diagnosed on core needle biopsy (CNB) remains controversial given highly variable rates of upgrade in the literature. Aim We sought to identify clinical and histologic factors that predict upgrade to atypia or malignancy in a large population. Methods and results A retrospective review was performed of all cases of pure IDP diagnosed on CNB and then surgically excised at a single institution from 2008 to 2018. Clinical, radiologic, and pathologic factors were compared in the no upgrade, upgrade to atypia, or upgrade to cancer groups. Univariate analysis was performed comparing no upgrade and upgrade to cancer or atypia. Four hundred and thirty nine patients were identified with a total of 490 IDP and a median age of 50 years (range 16–85). Of these patients, 54 (12.3%) were upgraded to atypia after surgical excision and five (1.1%) were upgraded to cancer. The presence of multiple papillomas in a single patient was a significant predictor of upgrade to cancer or atypia (p < .01), as well as age over ≥55 years (p < .01) and a prior history of cancer (p < .01). No other clinical, radiologic and histologic factors were found to be significant predictors of upgrade. 40/439 (9.1%) patients in the total cohort had prior history of cancer, and of these, 2/40 (5%) were found to have a new cancer after excision. Conclusions In patients with pure IDP on CNB, the upgrade rate to malignancy was 1.1%, while 12.3% were upgraded to atypia. The clinical significance of identifying atypia in a papilloma is unknown, especially in a patient with a prior history of atypia or cancer. However, the majority of patients who were upgraded to either atypia or cancer had no prior history of high‐risk or malignant breast disease and are therefore considered true clinical upgrades. As such excision for IDP should be considered.

A 26-year-old man presented with a 2-month history of a painless, reddish growth on his left eye. On physical examination, a sessile mass with vascular fronds was noted on the surface of the inferior bulbar conjunctiva.

Evaluation of radiologically detected breast lesions is a common task in surgical pathology. Some benign lesions on biopsy are associated with an upgrade to in situ or invasive carcinoma on excision. The non-atypical breast papilloma has published upgrade rates of 0 to 29%. Traditionally, papillomas have been managed surgically, but the wide range of upgrade rates has raised uncertainty about the need for routine surgical excision. This study aims to identify risk factors associated with upgrade and determine the upgrade rate of non-atypical papillomas at our institution. In a retrospective review of pathology reports, we identified 266 patients with a diagnosis of benign papilloma on breast core biopsy. One hundred eighty-two patients underwent surgical resection. The final surgical pathology reports of all patients were reviewed and divided into one of two groups—benign or malignant. Twenty-one patients had a final diagnosis of in situ or invasive carcinoma, resulting in an upgrade rate of 12%. Radiologically detected lesions with calcifications were at higher risk for upgrade (OR = 4.45, 95% CI 1.08–18.27) than lesions without calcifications. Additionally, advanced patient age (OR = 1.07, 95% CI 1.03–1.13) and lesion size greater than 0.5 cm (OR = 2.59, 95% CI 0.38–17.48) was associated with upgrade to malignancy. Routine surgical excision of all papillomas is not recommended. Younger patients without high-risk features may benefit from clinical and radiologic follow-up alone. Accurate risk stratification will spare low-risk women unnecessary surgery.

Background There is no consensus regarding the management of benign papillary breast lesions diagnosed on image-guided core needle biopsy (IGCNB). Methods This is a retrospective review of 407 patients within Kaiser Permanente Northern California diagnosed between 2012 and 2013. The study focused on patients presenting with a mass lesion and who were diagnosed with a benign papillary breast lesion (BPBL) on IGCNB. Patients who did not have surgical excision of the IGCNB papilloma were followed for at least 2 years. Results A total of 327 patients (80%) underwent surgical excision, 61 patients (15%) had follow-up imaging, and 19 patients (5%) had no surgery or imaging. Overall among women with surgical excision, 9.5% had a high-risk lesion, 3.4% had in situ cancer, and 2.4% had invasive cancer. An upgrade to an in situ cancer or invasive cancer was more common among women with a lesion greater than 1 cm, a palpable breast mass, age > 50 years, or if the lesion was > 5 cm from the nipple. No cancers were diagnosed in 61 women followed by imaging surveillance. Conclusions This is the largest, single-cohort study of benign papillary mass lesions diagnosed on IGCNB. On surgical excision, the overall rate of upgrade to in situ cancer and invasive cancer was low, and almost all cancers diagnosed had favorable features. Because no cancers were found in women who were followed by imaging, we conclude that outcomes for BPBL diagnosed on IGCNB are favorable whether surgical excision or surveillance is the treatment choice.

The diagnosis and management of tracheobronchial papilloma is challenging due to its rarity, and non-specific presenting symptoms. Small percentage undergoes malignant transformation. Herein, we report an unusual case of tracheal papilloma initially misdiagnosed as chronic obstructive pulmonary disease (COPD) in 36-year-old male with triple Y syndrome. It was successfully treated with local debridement and brachytherapy. To the best of our knowledge, this is the first description of brachytherapy for such a condition.

PurposeThis study aimed to analyze the clinicopathological features of ocular papilloma, a common benign tumor, and the risk factors related to its recurrence and partial deterioration.MethodsWe collected and analyzed the clinical information of 298 patients (51.68% males) with mean age of 41.54 ± 21.95 years, in the ophthalmology department of the West China Hospital. Clinical and pathological factors that might be related to papilloma recurrence and partial deterioration were studied.ResultsThe top three papilloma sites were bulbar conjunctiva, eyelid skin and palpebral conjunctiva. Moreover, 3.59% of lesions presented a malignant transformation, and 16.28% of patients had one or more recurrences after an average follow-up of 4.47 years. The multivariate logistic regression model showed that multiple lesions were a risk factor for recurrence (p = 0.022, OR = 3.088, 95% CI: 1.180–8.079), while cryotherapy decreased the recurrence risk (p = 0.044, OR = 0.364, 95% CI: 0.136–0.972). Additionally, elderly patients and lesions on the corneal limbus or cornea had a higher risk of malignant transformation (p = 0.004 and 0.01, OR = 1.086 and 7.827, 95% CI: 1.027–1.150 and 1.629–37.596, respectively).ConclusionOcular papilloma usually occurs in middle-aged and young patients, with no significant gender differences. Older patients and lesions on the corneal limbus or cornea are risk factors for partial malignant transformation. Finally, multiple lesions were a risk factor for recurrence, and cryotherapy reduced the recurrence rate.

This study compares the detection rates of haemoglobin absorption spectral imaging and white light imaging in laryngeal papilloma surgery. Seventeen patients with laryngeal papilloma who underwent surgery in our department from September 2019 to September 2021 were selected. All patients underwent carbon dioxide laser surgery under a microscope. The lesion sites were explored in white light mode and haemoglobin absorption spectral imaging mode. The pharynx and larynx anatomical sites were evaluated using Derkay's all-position scoring system. The numbers and scores for lesions observed in the two modes were compared. In 17 cases, there were statistically significant differences in the numbers of laryngeal papillomas (Derkay score) detected by white light mode and haemoglobin absorption spectral imaging mode. In 9 of 17 patients (52.94 per cent), the haemoglobin absorption spectral imaging mode showed additional diseased tissues. The haemoglobin absorption spectral imaging mode can dynamically identify diseased tissues in carbon dioxide laser surgery under a microscope and improve the laryngeal papilloma detection rate.

This study aims to investigate the efficacy of office-based potassium-titanyl-phosphate (KTP) 532-nm laser in the management of recurrent laryngeal papillomatosis (RLP) following other treatments. A retrospective assessment was performed on 55 patients in 259 cases of RLP between 2012 and 2019. Derkay scores were obtained for all patients who underwent 532-nm KTP laser procedure (6 W of power with a continuous output mode) prior to treatment and after treatment. Analysis of parameters is based on the distribution characteristics of data. An ordinal logistic regression was also performed. Patients received a median of 3 (range 1–24) office-based KTP laser treatments. Among them, 96.36% (53 patients) were previously on cold steel equipment, CO2 laser, or microdebrider treatment under general anesthesia, and all previous treatments on them had failed. One patient progressed to invasive cancer, so he was excluded from the following analyses. After final KTP treatment, 36 patients (66.67%) received complete resolution with follow-up time ranging from 12.9 to 80.53 months (median 55.54 months). Results of subjective voice-quality indicators such as VHI-30 and GRBAS all improved greatly at the last follow-up. The initial Derkay scores and treatment intervals were found to be predictive of complete lesion remission. Arytenoid involvement may also correlate with lesion resolution. Serial office–based KTP treatment is an effective option for RLP patients, with ideal disease control and voice quality preservation. KTP laser therapy should be repeated with an interval of 1 month from the beginning of treatment until the lesion has been evaluated and subsided. Non-bulk or scattered laryngeal papilloma is an appropriate indication for KTP laser treatment.
