RESUMO
Vulval fibroadenoma is an uncommon, benign tumor that originates from ectopic breast tissue or mammary-like glands in the anogenital region. Only a limited number of cases have been documented in medical literature. Typically occurring in young and middle-aged women, this condition, when surgically removed, generally exhibits a favorable prognosis with a low recurrence rate. We report a case of vulvar fibroadenoma wherein the patient exhibited a groin region mass. The mass was then excised and examined histologically. Histological examination of the polypoidal tissue section unveiled a clearly defined lesion comprising both epithelial and stromal components.
RESUMO
Hepatic angiomyolipoma (HAML) is a rare benign mesenchymal tumor with varying amounts of mature adipose tissue, smooth muscle cells, and thick-walled blood vessels. We present a rare case of hepatic angiomyolipoma (AML) with predominant lipomatous components. A 42-year-old female presented to the hospital with pain in the right lumbar region. On imaging, there was a large fat-predominant mass attached to the surface of the liver extending down to the lumbar region. On small biopsy, it was reported as a well-differentiated adipocytic neoplasm, and fluorescence in situ hybridization (FISH) studies performed for MDM2 were negative. On excision, histopathological examination showed predominantly fat components, but there were few epithelioid cells between adipocytes and thick-walled blood vessels. These cells were positive for Melan-A, HMB45, and smooth muscle actin (SMA) and negative for hepatocyte paraffin-1 (Hep Par1). Angiomyolipoma is a benign tumor and has a good prognosis with surgical excision. Few cases are associated with tuberous sclerosis.
