Identical Presentation of Scapular Osteolysis in Two Patients with Thoracic Kaposiform Hemangioendothelioma.

Kaposiform hemangioendothelioma (KHE) is a rare, locally aggressive vascular tumor that does not metastasize. We report two unique cases of KHE involving the right hemithorax and the upper ipsilateral extremity. Kasabach-Merrit phenomenon and osteolytic lesions in the scapula were observed in both cases.
