ABSTRACT

Angiomyxolipoma is a recently described and rare variant of lipoma that is characterized by the proliferation of adipose tissue with a myxoid stroma and multiple thick and thin-walled blood vessels. A 51-year-old man presented with a tender subcutaneous nodule on his right arm. The tumor was completely removed by excisional biopsy, and the histopathologic features revealed a thin fibrous capsule with incomplete fibrous septa extending into the lesion, dividing it into lobules of different sizes. The fat cells were mature, with a single vacuole and an eccentric nucleus. The vascular component consisted of groups of capillaries and occasional vessels of larger caliber. Erythrocytes were present within the lumen, and myxoid stroma was found. He was diagnosed as having angiomyxolipoma. Herein, we report a rare case of subcutaneous angiomyxolipoma of the arm. We also review and discuss such cases in the literature.

ABSTRACT

Angiomyxolipoma is a rare variant of lipoma and seven cases have been reported in the English literature. The reported cases mostly presented with a well-demarcated, asymptomatic, solitary, subcutaneous mass on the scalp or extremities. Histopathologic features of this tumor are characteristic and consist of the paucicellular myxoid areas and the mature fat tissue, with numerous thin, dilated blood vessels. The important histopathological differential diagnoses include myxoid spindle cell lipoma, myxoid lipoma, angiolipoma, angiomyolipoma, superficial angiomyxoma, myxoid liposarcoma and low-grade myxofibrosarcoma. We describe a 38-year-old man with multiple angiomyxolipoma on the gluteal area and the upper and lower extremities.
