Angioleiomyoma is a benign neoplasm that arises from vascular smooth muscle cells. Angioleiomyoma of the endometrium is very uncommon. The differential diagnoses of this entity are myopericytoma, angiomyofibroblastoma, endometrial stromal tumor, and perivascular epithelioid cell tumor. 31-year-old and 45-year-old patients presented with heavy menstrual bleeding, lower abdomen pain, and dysmenorrhea. Perspeculum and radiological investigations showed an endometrial polyp. They underwent diagnostic hysteroscopy, polypectomy, and endometrial biopsy...

Cellular angiofibroma (AF)/Angiomyofibroblastoma (AMF)-like tumor is a rare benign mesenchymal neoplasm. It is very challenging to distinguish benign versus malignant mass radiologically. It is of paramount importance to distinguish Cellular Angiofibroma (CAF) microscopically from its differential diagnoses. A 64-year-old man presented with scrotal swelling. Pathological examination showed features of cellular AF/AMF- like tumor, which shows positivity for CD34, with negativity for S-100 Protein, smooth muscle actin and desmin...

KEY CLINICAL MESSAGE: Angiomyofibroblastoma is a benign soft tissue tumor and a form of genital stromal mesenchymal tumor that primarily affects the vulva. It could possibly affect the reproductive-aged women's lower genital tract (vagina). ABSTRACT: Angiomyofibroblastoma is a rare benign soft tissue tumor primarily affecting the vulva in reproductive-aged women. We report a 67-year-old female complaining of a painless mass in her right vulva spreading to the right inguinal region over the past 2 years...

Cellular angiofibromas (CAFs) are infrequent and benign soft-tissue tumors that primarily affect the genitourinary region in both genders. The authors report the case of a 71-year-old male patient who exhibited progressively increasing swelling in both testicles, with greater prominence noted on the left side. Initial findings from physical examination and scrotal ultrasound indicated the possibility of bilateral hydrocele, so the patient was recommended surgical intervention of the left more prominent side...

BACKGROUND: Angiomyofibroblastoma (AMFB) is an uncommon disease with few literature reports, leading to the poor understanding of its diagnosis, treatment, and postoperative follow-up plans among gynecologists. OBJECTIVE: To study the clinical and pathological features of vulvar AMFB and discuss its treatment and prognosis. CASE SUMMARY: The 3 cases were characterized by a gradually increasing painless mass in the vulva. Preoperative diagnosis was difficult and mainly depended on ultrasonic examination...

BACKGROUND: Cellular angiofibroma (CA) is a rare, benign mesenchymal tumor first described by Nucci et al. (Am J Surg Pathol 21:636-644, 1997. 10.1097/00000478-199706000-00002). It affects both men and women, although it is more common in middle-aged women. CA is well circumscribed and usually observed on the body surface, primarily in distal genital regions. Aggressive angiomyxoma and angiomyofibroblastoma are clinically and histologically similar; therefore, it may be necessary to distinguish between CA and these similar tumors...

Introduction Mesenchymal tumors of the lower female genital tract (FGT) are a miscellaneous group of tumors that include aggressive angiomyxoma (AAM), angiomyofibroblastoma (AMFB), cellular angiofibroma (CAF), and related entities. Histologically, these tumors are composed of stromal cells admixed with vessels, with some minor histological differences. An accurate diagnosis of these tumors is important owing to the differences in the outcome. In this study, we determined the clinicopathological characteristics of these tumors in our population and their association with recurrence...

Angiomyofibroblastoma (AMF), a rare benign vulvovaginal mesenchymal tumour, poses a diagnostic challenge due to histologic and immunohistochemical overlap with other vulvar mesenchymal tumours. Recently, MTG1-CYP2E1 fusion transcripts were reported in 5/5 AMFs; no other genetic alterations have been described to date. Herein, we sought to investigate the frequency of the MTG1-CYP2E1 fusion and the presence of other potential genetic alterations in a cohort of AMFs (n = 7, patient age range: 28-49 years)...

Angiomyofibroblastoma (AMF) is a rare benign soft-tissue tumor that most frequently affects the lower genital tract of young to middle-aged women. It mainly consists of two components: stromal cells and prominent vasculature. Clinically, it is usually asymptomatic and resembles Bartholin's cyst. Although it is a benign tumor, cases with recurrence and sarcomatous transformation have been reported. Due to the overlapping of histopathological picture, diagnostic perplexity often arises between AMF and aggressive angiomyxoma (AAM)...

This article provides an update of the recent developments in mesenchymal tumors of lower genital tract. We focus on the characterization of recurrent molecular events in certain genital stromal tumors, for instance angiomyofibroblastomas and superficial myofibroblastomas. Moreover, fusions involving Tyrosine-kinases receptors (NTRK, FRFR1, RET, COL1A1-PDGFB) have been demonstrated in an emerging group of mesenchymal tumors characterized by a fibrosarcoma-like morphology and a predilection for uterine cervix of premenopausal women...

Angiofibromas, also known as angiomyofibroblastoma-like tumors or AMF-like tumors, refer to a collection of rare, benign yet highly cellular tumors of the vulva, scrotum, perineum, or inguinal region. In this paper, we present a 34-year-old Saudi man who presented with findings of a testicular tumor on physical examination and imaging and tested negative for all the markers associated with testicular tumors.

Angiomyofibroblastoma (AMF) is a rare benign myofibroblastic tumor that mainly occurs in the genital tract of middle-aged female patients. However, it can also arise in the scrotum, spermatic cord, and bladder. We described, herein, a case of a 42-year-old patient who was admitted to our hospital with a left scrotal mass. Imaging examinations showed that the mass had abundant vessels and displayed obvious progressive intensification on enhanced MRI. The following histopathological and immunohistochemical studies led to the diagnosis of AMF...

BACKGROUND: Deep angiomyxoma (DAM) is currently included in the category of "specific stromal tumors of the lower female genital tract", along with angiomyofibroblastoma, cellular angiofibroma and myofibroblastoma. Given the high rate of local recurrences, it is crucial to recognize DAM from other tumors that possess indolent behaviour. In the present paper, we analyzed the morphological and immunohistochemical features of 42 surgically-resected vulvo-vaginal DAMs (36 primary and 6 recurrent lesions) in order to widen the morphological spectrum of this uncommon tumor...

Összefoglaló. A scrotum képalkotó vizsgálóeljárásai közül elsőnek választandó az ultrahang, mivel könnyen hozzáférhető, szenzitivitása és specificitása magas. Szerepe kiemelendő mind az intratesticularis eltérések differenciáldiagnózisában, mind pedig a kevésbé ismert paratesticularis eltérések esetében. Az urológiai ambulancián egy 56 éves férfi jelentkezett kivizsgálásra tapintható terime miatt. Ultrahangvizsgálattal paratesticularis elváltozás látszódott, mely a vizsgálat során az inguinalis csatorna irányába többször elmozdult...

Angiomyofibroblastoma and superficial myofibroblastoma are distinctive benign mesenchymal tumors occurring in the female lower genital tract. Despite their significant overlapping clinicopathologic features, including the presence of bland-looking spindle or oval cells with myofibroblastic or myoid differentiation, the tumors have been regarded as separate entities. Although subepithelial, hormone-sensitive mesenchymal cells of the female lower genital tract are considered as their potential common progenitor cells, their potential kinship or pathogenetic similarities remain elusive...
