Capillary hemangioma associated with dermal atrophy masquerading as a deep fungal infection.

Hemangiomas are benign vascular neoplasms which arise in early adulthood. Herein we present a 79-year-old woman with a hemangioma of the lower flank masquerading as a cutaneous manifestation of a systemic fungal infection upon initial histological analysis. Decreased elastin and collagen within the lesion likely accounted for the clumping and splaying of the capillaries into "hyphae-like" structures. Loss of dermal elastic tissue and collagen apparently concentrated the capillary proliferation into an unusual morphology mimicking the hyphal structures. Through additional staining methods the lesion was confirmed to be an unusual presentation of a capillary hemangioma.
