Primary osteogenic sarcoma of a finger proximal phalanx: a case report and literature review.

Osteogenic sarcoma of the small bones of the hand is rare with only 15 cases documented. We describe a 12-year-old boy with an osteogenic sarcoma of the proximal phalanx of the middle finger. Wide excision in the form of ray amputation with a wide surgical margin was performed after neoadjuvant chemotherapy consisting of combined high-dose methotrexate, doxorubicin, ifosfamide, and cisplatin. To restore maximum function the index ray was transferred to the base of the third metacarpal. Adjuvant chemotherapy was administered subsequently. At 28-month follow-up evaluation there was no evidence of local recurrence of disease or distant metastasis and both function and appearance were good.
