Angiomyomas are rare benign smooth muscle tumors originating from the tunica media of blood vessel walls, most frequently affecting the lower extremities in middle-aged women. We report the case of a 51-year-old female with a six-month history of a painful, palpable mass in the right heel. Physical examination revealed a soft, mobile, and tender subcutaneous nodule. Ultrasound imaging identified a 0.5 cm well-defined hypoechoic lesion in the subcutaneous layer, without internal blood flow, initially suspected to be an epidermoid cyst or fibrous tumor. Surgical excision of the lesion was performed, and histopathological analysis revealed a well-encapsulated tumor consisting of spindle-shaped cells with eosinophilic cytoplasm and bland nuclei, accompanied by vascular components. Immunohistochemical staining confirmed positive expression of SMA, establishing the diagnosis of angiomyoma. The patient experienced an uneventful postoperative recovery. This case highlights the diagnostic challenges of angiomyomas, given their nonspecific clinical presentation and imaging findings. While magnetic resonance imaging may reveal characteristic features such as strong gadolinium enhancement, definitive diagnosis relies on histopathological evaluation. Clinicians should include angiomyoma in the differential diagnosis of painful subcutaneous masses in the foot and ankle, particularly in middle-aged women. Surgical excision remains the definitive diagnostic and therapeutic approach, with low recurrence rates reported.

Introduction Angioleiomyoma, a vascular leiomyoma is a rare, benign smooth-muscle tumor observed to occur anywhere in the body, most frequently in the lower extremities but very rarely in the digestive system. Angioleiomyoma in the hindgut is infrequent and in particular, rectal/perianal location has been observed very rarely. Case report We describe herein a case of a 50-year-old male patient complaining of perineal discomfort and a swelling at the level of the left ischio-rectal fossa, moderately painful. This solid mass in the left ischio-rectal space was in close relationship with the wall of the ano-rectal junction. After surgical removal and histopathology, the mass resulted an angioleiomyoma, vascular type, desmin positive, a very rare neoplasm. Extensive immune-histochemical studies are fundamental for the correct diagnosis and to rule out other mesenchymal tumors. Discussion/conclusion. Angioleiomyoma is a very rare neoplasm of the gastrointestinal tract, and the fundamental problem of peri-rectal/perianal angioleiomyoma is represented by differential diagnosis from gastrointestinal stromal tumors (GISTs) and other perianal/perirectal swellings. For correct differential diagnosis, the histopathology supported by extensive immune-histochemical study adopting a panel of specific tissue markers is important. The surgical treatment is mandatory with complete excision and subsequent follow-up since local recurrence may occur.

PurposeAngioleiomyoma, predominantly arising from the extremities, is a benign soft tissue tumor. Reports on its intracranial location are rare. We assessed clinical, radiological, and pathological features of intracranial angioleiomyoma (iALM) treated at our neurosurgical institution.MethodsWe consecutively enrolled all patients with neuropathologically confirmed iALM treated at a single neurosurgical institution between 2013 and 2021. Clinical and imaging data were collected, and histological tissue sections were analyzed. A review of the literature on iALM was conducted.ResultsSeven patients with iALM (four female) with a median age of 45 years (range: 32–76 years) were identified. In three cases, the lesion was found incidentally. In magnetic resonance imaging (MRI), all tumors were hypo- to isointense on T1-weighted, hyperintense on T2-weighted sequences, and gadolinium-enhancing. A strong FLAIR signal was seen in six patients. Surgery consisted of gross total resection in all cases without perioperative complications. Neuropathological staining was positive for smooth muscle actin (SMA) in all lesions. Mature smooth muscle cells arranged around blood vessels were typically observed. The Ki-67 index was ≤ 3%. The patients were discharged after a median of 6 days (range: 4–9 days). During a median follow-up time of 14 months (range: 4–41 months), no tumor recurrence occurred. In the current literature, 42 additional cases of iALM were identified.ConclusionIntracranial angioleiomyoma is a benign soft tissue tumor treated by gross total resection. Tumor morphology and positive staining for SMA lead to the neuropathological diagnosis.

ObjectiveTo identify the characteristic magnetic resonance imaging (MRI) findings in angioleiomyoma and to clarify its relationship with histopathological findings.Materials and methodsWe retrospectively analyzed the MRI findings and pathological subtypes in 25 patients with subcutaneous angioleiomyoma of the extremities. Based on the previous reports, MRI findings that could be characteristic of angioleiomyoma were extracted. According to the World Health Organization classification, all cases were classified into three pathological subtypes: solid, venous, and cavernous. The relationship between MRI findings and pathological subtypes was analyzed.ResultsThe pathological subtypes were solid (n = 10), venous (n = 11), and cavernous (n = 4). The following MRI findings were observed: (a) hypo- or iso-intense linear and/or branching structures on a T2-weighted image (positive total/solid/venous/cavernous: 19/5/10/4, respectively), which we defined as “dark reticular sign”; (b) peripheral hypointense rim on a T2-weighted image (positive total/solid/venous/cavernous: 19/7/8/4, respectively); and (c) presence of any adjacent vascular structures (positive total/solid/venous/cavernous: 6/3/3/0, respectively). Chi-square test showed a significant relationship between dark reticular sign and pathological subtypes (p = 0.0426). The dark reticular sign was found more frequently in the venous and cavernous types than in the solid type. The other MRI findings did not reveal a significant relationship between pathological subtypes.ConclusionWe present the largest case series exploring MRI findings in angioleiomyoma. The dark reticular sign was a characteristic MRI finding of angioleiomyoma and was seen in most of the venous and cavernous types, which may facilitate preoperative diagnosis.

This article presents a female patient in her 40s who presented with a tender violaceous bump on her upper right lip. Our primary differential diagnosis was an arteriovenous malformation. Punch biopsy revealed the lesion to be an angioleiomyoma (ALM). The punch biopsy was sufficient for the complete removal of the lesion, and the lesion did not recur to date. There were no complications. We discuss the dermatoscopic description of an ALM and its clinical picture.

Background An angiomyofibroblastoma (AMF) is a rare tumor that primarily occurs in the vulva of women. AMF rarely occurs in the inguinal region and scrotum of men. Case presentation A 59-year-old male was admitted to the hospital for evaluation of left scrotal enlargement for 2 years. A physical examination revealed no elevation in the bilateral renal or suprapubic region. The bladder was located below the pubic bone and was non- tender without pressure. Auscultation revealed no abnormalities in the right or left renal regions. The left scrotum was enlarged with a palpable mass measuring 25 × 15 cm in size. The mass was characterized by a tough, smooth surface with a clear boundary. The left testis was not palpable and the transillumination test result was negative. Magnetic resonance imaging included an abnormal signal in the scrotum, which was consistent with a space-occupying germ cell tumor but other diagnoses could not be ruled out. The preoperative preparation indicated no contraindications to surgery. Under lumbar anesthesia, the left scrotal lesion was resected. The postoperative pathologic evaluation confirmed an AMF. Currently, the patient has recovered fully without complications. Conclusion A large-sized AMF is relatively rare in the male scrotum, but reported in this case. A scrotal AMF often has an oval shape with no palpable pain. Imaging techniques can facilitate the hypervascular status of an AMF and pathologic findings can establish the diagnosis. However, reports of scrotal AMF are limited. A more thorough understanding should be achieved with additional cases and long-term follow-up.

We present a novel case of a malignant transformation of an extremity soft tissue angioleiomyoma to leiomyosarcoma in a man in his late 70s who presented with a painful and increasing lump on his anterior tibia. Initial imaging and biopsy showed a benign angioleiomyoma which was excised for symptomatic reasons. An analysis of the resulting specimen revealed a 50×42×15 mm smooth muscle neoplasm consistent with angioleiomyoma with a 22×11 mm entirely intralesional nodular component in keeping with a grade 1 leiomyosarcoma. The malignant constituent of the lesion was entirely encased in benign angioleiomyoma negating the need for further surgery. Systemic staging investigation revealed no evidence of metastatic disease spread final staging as per the eighth edition of the American Joint Committee on Cancer (AJCC) Staging T1N0M0 R0 Stage 1 a.

Background Angioleiomyoma, a benign tumour composed of smooth muscle cells and thick-walled vessels, is expected to be very rare in the female genital tract. This study aimed to describe the clinicopathological features and treatment outcomes of angioleiomyoma in the female genital tract. Methods We retrospectively reviewed 89 women with angioleiomyoma in the genital tract who were treated at Third Xiangya Hospital of Central South University between July 2008 and October 2023. Symptom remission rate was the primary outcome of the study. Results Angioleiomyomas accounted for 0.6% of leiomyomas of the female genital tract. The average age of the 89 women was 41.8 ± 8.7 years. Seventy women (78.7%) had a history of uterine surgery, of whom two patients had removed uterine angioleiomyoma by laparoscopic myomectomy. The angioleiomyomas of 61 (68.5%) women were located in the uterine corpus, 17 (19.1%) in the broad ligament, 10 (11.2%) in the cervix and only 1 (1.1%) in the vagina. Abnormal uterine bleeding was the main clinical manifestation of angioleiomyomas located in the uterine corpus or cervix, whereas the main clinical manifestation of angioleiomyomas in the broad ligaments was pelvic mass. Of the 89 women, 59 underwent surgery to preserve the uterus, and 30 underwent total hysterectomy or subtotal hysterectomy. The intraoperative blood loss was more than 500 ml (700–4,500 ml) in six women. The symptom remission rate was 100% after surgery. Among the 59 women with preserved uterus, 8 showed multiple uterine leiomyomas during follow-up, but it was difficult to determine whether they were angioleiomyomas. Angioleiomyomas recurred in one women who underwent total hysterectomy. Conclusion Angioleiomyoma is rare in the female reproductive tract, and patients may present with diverse symptoms, which are related to the location of the tumour. Hysterectomy and myomectomy are both effective treatment methods, but the risk of intraoperative bleeding should be recognised for multiple lesions and those with large diameters. Relapse may occur in some patients.

Background Uterine angioleiomyoma is benign tumor that composed of smooth muscle cells and thick-walled vessels. It is a very rare condition reported to present as lower abdominal mass, accompanied by dysmenorrhea and hypermenorrhea. However, its clinical presentation is not known. Case presentation We report the case of a 44-year-old Japanese woman who developed severe anemia with disseminated intravascular coagulation without obvious external bleeding. The patient had a huge abdominal mass of over 20 cm in size, which was thought to be a uterine tumor. She received daily blood transfusions and her condition improved rapidly after she underwent hysterectomy. Pathological examination of the tumor revealed spindle-shaped cells with little atypia and mitosis, and numerous large vessels with smooth muscle and thrombus in the vessels. Conclusions Uterine angioleiomyoma was identified as the cause of the coagulation abnormality. CCND2 and AR gene amplification was detected in the tumor. Uterine tumors that present with coagulopathy despite a clinical course suggestive of benign disease should undergo differential diagnosis for uterine angioleiomyoma.
