Epithelioid haemangioma--angiolymphoid hyperplasia with eosinophilia. Case report and review of literature.

Epithelioid haemangioma (angiolymphoid hyperplasia with eosinophilia: ALH) is a rare tumour most often affecting the skin and subcutaneous tissue in young adults. Unusual findings in the present case included deep location oft the lesion with involvement of striated muscle and periosteum which complicated clinical diagnosis. These tumours are generally composed of proliferating small vessels with prominent endothelial cells and heavy inflammatory infiltrate made up of lymphocytes, lymphoid follicles, plasma cells, mast cells, and especially eosinophils. The lesion is benign, and local excision is curative. Clinical manifestation and morphological characteristics of this rare lesion are described in this paper and are compared with other cases reported in the literature.
