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.

BACKGROUND: Juvenile xanthogranuloma is a benign, self-limited disorder that usually occurs in infants and young children. Xanthogranuloma is rare in adults, and therefore studies reporting adult xanthogranuloma are limited. OBJECTIVE: We investigated the clinical, histopathological, and immunohistochemical characteristics of adult xanthogranuloma. METHODS: In this study, we evaluated 20 lesions in 19 patients with adult xanthogranuloma. RESULTS: A male predominance was observed (male : female ratio 1.4 : 1), and the mean age of patients was 35.1±16.3 years (range 15∼66 years), with the peak incidence observed in patients in their 20s. Notably, 65.0% of the lesions developed on the head and neck. The nodular form was more common than the papular form of this condition. Histopathological examination revealed dense monomorphic histiocytic infiltration without lipidization and scattered eosinophils without multinuclear giant cells in 5 lesions (25.0%), foamy histiocytic infiltration with variations of completely developed Touton giant cells in 10 lesions (50.0%), and fibrohistiocytic proliferation in 3 lesions (15.0%). On immunohistochemical examination, histiocytes including giant cells showed positive test results with Factor XIIIa (90.9%), vimentin (100%), and CD68 (100%) and negative test results with CD1a, smooth muscle actin, and S-100 protein stains. Tumor excision was the treatment for choice. CONCLUSION: Adult xanthogranuloma most commonly manifested as the nodular form of the disease on the head and neck of men in their late 20s. Histopathologically, the classic Touton cell-rich stage was most commonly observed, followed by the stage of early predominantly mononuclear infiltration. This was a single-center, small-sized retrospective study; however, we expect the results of this study to contribute to a better understanding of adult xanthogranuloma.
