Vaginal Angiomyofibroblastoma: A Case Report and Review of Diagnostic Imaging

Cellular Angiofibroma of the Perineal Region With Tortuous Vessels: A Report of Three Cases

Cellular angiofibroma (CA) is a slow-growing, painless benign soft tissue tumor that commonly arises in the superficial soft tissue of the vulvovaginal or inguinoscrotal regions. Since CA shares many pathological and imaging similarities with angiomyofibroblastoma and aggressive angiomyxoma, its preoperative imaging diagnosis can be challenging. To the best of our knowledge, this is the first report describing tortuous vessels around the tumor as imaging findings to assist in diagnosing CA and distinguishing it from angiomyofibroblastoma and aggressive angiomyxoma in the perineal region.

Cellular angiofibroma of the female pelvic cavity: a case report

BACKGROUND

Cellular angiofibroma is a rare benign mesenchymal tumor that mostly occurs in the genital area. Its occurrence outside this region, particularly in the pelvis, is extremely rare. To our knowledge, this study reports the first case of cellular angiofibroma occurring in the pelvic cavity, except for one case reported in the retroperitoneum.

CASE PRESENTATION

A 25-year-old female patient with chronic, intermittent, dull pain in the lower abdomen that lasted for several months was referred to our clinic. Imaging studies revealed a tumor in the pelvic cavity anterior to the bladder. The radiographic characteristics of this tumor indicated a hypervascular nature, suggesting the possibility of a pheochromocytoma or a neuroendocrine tumor. The patient underwent surgical excision of the lesion. To date, no recurrence has been observed four months after excision.

CONCLUSIONS

Cellular angiofibroma, although rare in the pelvic cavity, should be considered in the differential diagnosis of hypervascular pelvic space-occupying lesions. Immunohistochemical staining can help confirm the diagnosis of this condition. Treatment is generally straightforward, involving local excision of the tumor followed by postoperative monitoring.

Cellular angiofibroma in the retroperitoneal space during pregnancy: A case report

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. We present a rare case of CA, with atypical features, in the retroperitoneal space during pregnancy.

CASE PRESENTATION

The presence of a 130 mm tumor was detected in a 19-year-old woman. The tumor, located in the retroperitoneal space, was found during first pregnancy examination. At 16 weeks of gestation, the woman developed nausea and fever, and it was diagnosed with acute pyelonephritis. After a few days, the amniotic membranes prematurely ruptured, leading to a miscarriage. The woman underwent a tumor resection, after miscarriage. This case presented with atypical features of CA. This included the young age of the patient, and presence of a tumor in the retroperitoneal space.

CONCLUSION

In this case, the diagnosis of CA was difficult due to the rarity of the disease and its atypical clinical features. From this experience, we recommend that the discussion on the efficacy of surgical treatment and pregnancy outcomes should be done based on individual case, and not generalized.

Superficial myofibroblastoma of the vagina with a stalk: case report of a rare vaginal tumor with notable radiological findings

Superficial myofibroblastoma is a rare benign mesenchymal tumor which predominantly occurs in the female lower genital tract. Here we present a case of a 42-year-old female patient with prolonged vaginal bleeding. Radiological imaging revealed a well circumscribed mass in the vagina with a stalk. The patient underwent surgery and the tumor was histologically diagnosed as superficial myofibroblastoma. Notably, this is the first report of the radiological imaging of a superficial myofibroblastoma harboring a stalk arising from the vaginal wall. We compared the radiological images with histological findings and discuss major differential diagnosis of vaginal tumors. Despite the challenging nature of preoperative diagnosis of mesenchymal vaginal tumors, radiological features may aid in differentiating them from other more aggressive entities or malignant tumors.

Rare case of huge vulvar angiomyofibroblastoma in a young female

•

Huge angiomyofibroblastoma of the Vulva.

•

Differential diagnosis between vulvar angiomyofibroblastoma and vulvar aggressive angiomyxoma.

•

Comprehensive approach diagnosing and therapy of vulvar angiomyofibroblastoma.

Mesenchymal tumours of the vulva are rare and consist of two types, difficult to distinguish but with different prognoses. Angiomyofibroblastoma (AMFB) is a benign tumour, whereas Aggressive Angiomyxoma (AA) is an infiltrating tumour. We describe a 22-year-old nulliparous patient with a vulvar mass sized 19 cm in diameter. After preoperative assessment by ultrasound, chest X-ray, and MRI, wide excision on the tumour was done and diagnosed as AMFB. Differentiation from AA is being discussed.
