Atypical Linear Verrucous Hemangioma on the Upper Extremity / 대한피부과학회지

ABSTRACT

Verrucous hemangioma (VH) is a rare vascular malformation, a structural variant of capillary or cavernous hemangioma, with reactive epidermal changes. Most VHs have been known to locate on the lower extremities and develop from birth or childhood. The patient was a 17-year-old girl and presented multiple dark red colored, verrucous, hemangiomatous nodular plaques affecting nearly all of the left arm with linear distribution. Skin biopsy revealed epidermal hyperkeratosis with irregular acanthosis, and diffuse proliferation and dilatation of blood vessels in dermis and subcutis. This is an interesting case of VH affecting nearly total left arm with linear distribution.
