Intravascular papillary endothelial hyperplasia is a relatively rare disease which is characterized by the development of endothelial-lined papillary projections in a vascular lumen. It is commonly found to be associated with thrombotic material
and is
now considered a reactive process of the endothelium rather than a neoplastic one. Although this disease usually presents a reddish or bluish nodule on the head, neck or upper extremities, it can develop anywhere on the body. There are many
reports
about lesions in unusal locations, byt they are almost always solitary.
A 61-year-old woman complained of multiple, tender. 1×1 to 4×5 cm sized nodules on both hands, antecubital fossa, chest, abdomen, left shoulder and right calf. These thirteen nodules showed reddish to bluish colors and had long histories from 1
year
to 7 years. Four out of 13 lesions were excised for histopathologic diagnosis : intravascular papillary endothelial hyperplasia in 3 lesions and cavernous hemangioma in 1 lesion.(Kor J Dermatol 1995;33(2) : 322~326)
