Primary xanthoma of calcaneus bone: Case report

چکیده
INTRODUCTION Xanthoma (or xanthofibroma) is a benign proliferative lesion, mostly seen in soft tissue. Xanthoma of bone is very rare benign primary bone tumor, more frequently seen in men and in patients over 20 years of age. Histologically, it is characterized by mononuclear macrophage-like cells, abundant foam cells, and multinucleated giant cells. It is sometimes discovered coincidentally and the most frequent symptom is pain. PRESENTATION OF CASE We present a 50-year-old healthy male patient with primary xanthoma of the calcaneus, who was treated by curettage and bone cement. He presented with a pathological fracture in a calcaneus bone lesion. Giant cell tumor was suspected on X-ray and MRI. Curettage and bone cementing was done through the posterolateral approach. Lipid profile was normal and histological examination revealed findings consistent with primary xanthoma of calcaneus bone. DISCUSSION To avoid an erroneous diagnosis, all material should be examined microscopically, the radiological features of the lesion should be studied properly and lipid profile should be investigated to differentiate between primary and secondary xanthoma. Primary xanthoma may be treated with curettage and bone graft while secondary xanthoma is treated nonsurgically and the skeletal manifestations will disappear with systemic treatment of hyperlipidemia. CONCLUSION We present this case to raise the suspicion of this lesion that is rarely described in the literatures. This is the first case of primary xanthoma of calcaneus bone that has been reported in Qatar.

Intraosseous lipoma is a rare, benign primary tumor occurring in the bone. Herein, we reported a 45-year-old manwith chronic right posterior heel pain. In this study, the man was treated conservatively due to plantar fasciitis. Duringa one-month follow-up visit, the patient had no symptoms of relief in the right heel pain. Initially, calcaneal X-raywas taken, which revealed an...

A case of bilateral intraosseous tumor of the calcaneus with different MRI imaging is presented. On the left, radiological findings suggest intraosseous lipoma, but on the right-sided lesion, imaging studies were not convincing. The microscopic report showed foreign body granulomatous reaction, a rare clinical pathological discordant.

We report the case of a 25-year-old woman presenting with left hip pain. A lesion was found in the proximal femoral metaphysis. Benign bone tumor, such as intraosseous lipoma or liposclerosing myxofibrous tumor, was suspected based on simple radiographs and magnetic resonance images. Curettage of the lesion and bone grafting was performed. Histologic findings reflected primary intraosseous xant...
