A primary solitary vascular tumor of calcaneum: case report and review of literature.

Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor with metastatic potential and estimated prevalence of less than one case per million. Among the musculoskeletal system, the long bones are commonly involved with approximately half patients experiencing multicentric involvement. Clinical course of EHE is often variable and nonspecific. Poorly demarcated osteolytic lesions are most commonly seen radiologically. Diagnostic confirmation is usually obtained by biopsy and histopathological exam, including immunostaining for endothelial markers. We present a rare case of unicentric EHE involving the calcaneum. Our patient had an indolent course of disease after surgical resection and no recurrence in seven years on clinical and radiological surveillance.
