Enchondroma - A Case Study

History A 62 year old female patient, presented with pain in left thigh. Duration of pain 3 months. Insidious in onset, dull aching type, moderate degree, non- radiating. Aggravated on standing/walking and partially relieved on taking rest and analgesics. No h/o trauma, any other bony pain or similar history in the past. No co-morbid conditions. On Examination No swelling, scar, sinus seen. No skin changes. No local rise of temperature. Tenderness + over lateral condyle of left femur. No other bony or joint line tenderness. Full range of movement present but terminal 10 degrees painful. No distal neuro-vascular deficits. Investigations xrays, mri and Ct done. Treatment curettage, excision & bone grafting done. Posteopartively patients was followed upto 3 months. Review of literature Chondromas are benign lesions of hyaline cartilage. Chondromas are usually asymptomatic and are frequently discovered incidentally during an unrelated radiographic examination. They also can be discovered after a pathological fracture. It is caused by failure of normal enchondral ossification. Chondromas are more common between 10-50 years of age. Most common locations are small tubular bones of hands and feet. Radiographically, Enchondromas are benign-appearing tumors with intralesional calcification. The calcification is irregular and has been described as stippled, punctate, or popcorn. Microscopic appearance is that of a mature hyaline cartilage. The differentiation of benign from malignant cartilaginous tumors is one of the most difficult problems in bone pathology. All available tissue must be examined, and even then the diagnosis may depend more on the clinical and radiographic features tha n on the microscopic changes. Treatment of patients with solitary enchondromas usually consists of observation with serial radiographs. If a lesion grows, or becomes symptomatic, extended curettage with or without bone grafting usually is curative. Peculiarities in the case Age of the patient- 62 years, Location of tumour Distal Femur (small tubular bones of hands & feet), Benign lesion in 7th decade.
