We present a case of subperiosteal giant-cell reparative granuloma followed over six years showing the complete evolution from the early phase of subperiosteal haematoma to the end stage of an ossified haematoma. Such lesions, although they are histologically similar to true giant-cell tumours, can be distinguished by the patients' age, their location on the diaphysis, and by their radiological and histological features.

The laboratory studies showed an increased alkaline phosphatase of 523 units, a total protein of 8.2 mg, and a globulin of 4.4 mg. The cholesterol level was 159 mg/dl. The hemoglobin was 13.1 g, and

A rare developmental anomaly of absent posterior tibial artery and hypoplastic anterior tibial artery is presented. In this case, marked hypertrophy of the peroneal artery compensated for the absent arteries. The peroneal artery also gave collaterals to form the dorsalis pedis and the plantar arteries.
