RESUMEN
Patellar tumors are rare and are usually benign as opposed to malignant tumours. The most frequent benign lesions of patella are giant cell tumor (common in adults), chondroblastoma and osteoid osteoma. A solitary exostosis is the most common benign bone tumor which occurs around the growth plate of long bones. The treatment of choice is extra periosteal resection of exostosis and ensuring complete removal of cartilaginous cap. Indications of surgery are when the exostosis is interfering or disturbing the growth of extremity, malignant transformation, presence of bone erosion, neurovascular compression, interference with joint motion, bursitis, fracture through the stalk and cosmesis. We report a rare case in an adult patient with an extra-articular skeletal osteochondroma of the patella located antero - superiorly which presented as an enlarged bursa and a bony swelling over knee joint.
RESUMEN
A 22-year-old female presented with rapidly increasing, fungating and painful growth of right foot of 4 months duration. The growth had superadded infection. Radiography revealed soft issue mass between 2nd and 3rd toes without any bony involvement. Histopathologically it was confirmed to be a case of extraskeletal Ewing's sarcoma. Amputation above the ankle was done. She was advised for chemotherapy. She is still alive after 2 years. Here in this case the tumour arose in the subcutaneous tissue between 2nd and 3rd toes and diagnosed as a case of Ewing's sarcoma of the foot.
