A solitary osteochondroma of middle phalanx of the hand in an adult: A case report and differential diagnosis

Abstract

Introduction: Solitary osteochondroma of phalanx of the hand in an adult are extremely rare and have different presentations depending on the site of origin. Most adult solitary tumour arises either from the distal phalanx or in the carpal bones. Importance of the lesion lies in its various differential diagnoses. We present a rare case report of solitary osteochondroma of the middle phalanx left index finger in an adult. Management and differential diagnosis is discussed. Presentation of Case: 32 year old male presented with osteochondroma arising from dorsal ulnar side of middle phalanx left index finger with limitations of movements at PIP and DIP joint. Patient achieved full finger movements after excision and no recurrence at 18 month follow-up. Conclusion: Solitary osteochondroma of the middle phalanx in an adult is a rare osteocartilaginous lesion. In view of a varied differential diagnosis and a high rate of local recurrence, an early identification and a wide excision is essential.
