Masson Tumor of the Heel Fat Pad.

Abstract

Intravascular papillary endothelial hyperplasia (Masson tumor) is an uncommon benign vascular lesion characterized by a reactive proliferation of endothelial cells. This lesion commonly occurs in the head, neck, and upper extremities. Although it can be found anywhere in the body, the lesion has never affected the heel fat pad. This report presents a rare case of Masson tumor of the heel fat pad to facilitate the recognition of this uncommon lesion and also suggests other conditions to be considered when diagnosing heel lesions.
