Eosinophilic Granuloma

Eosinophilic granuloma (EG) is a solitary, non-neoplastic proliferation of histiocytes. EG is part of a spectrum of Langerhan's cell histiocytosis, formerly known as histiocytosis X.
The male to female ratio is two to one. It occurs most commonly in children aged 5 to 10 and is uncommon in blacks.
EG is normally symptomatic. Local pain, swelling and tenderness are common and the ESR may be elevated.The radiologic appearance of EG is non-specific and differs by location.

Epithelioid Hemangioma

Epithelioid hemangiomas, also known as angiolymphoid hyperplasia with eosinophilia and histiocytoid hemangioma, are benign vascular tumors that usually occur in the skin and subcutis. They have the potential to occur at any skeletal site. The paucity of cases reported has hindered in determining specific areas of skeletal manifestation.
Males and females are equally affected, with an age presentation between 7-74 years old.
Clinically, patients usually present with pain over the involved sites.On X-ray, epithelioid hemangiomas are well-defined lytic lesions that involve the metaphysis and diaphysis of long bones. Peripheral sclerosis may be seen around the margin.
