Myxoma of the femur: an unusual site of origin.

Skeletal myxomas are rare benign tumours. Their occurrence in long bones of the extremities is rarely reported. A 45-year-old man presented with pain in his left proximal thigh for a duration of 4 months. Movements of the hip were painful. Radiography revealed an expansile osteolytic lesion in the left proximal femur near the lesser trochanteric region. On MRI, the lesion showed a homogenous signal enhancement with no cortical disruption. Extended curettage and bone grafting was performed. On gross examination, the curetted specimen was a yellowish-white mucoid material. Histopathology showed a tumour consisting of spindle-shaped and stellate-shaped cells with widely separated myxoid mucoidy stroma, suggestive of intraosseous myxoma. At 2 years follow-up, there were no signs of recurrence and the patient was doing well with excellent hip and knee function.
