Hamartoma of the Finger: A Case Report

Hamartomas are benign masses of disorganised tissue native to specific anatomical sites, with a potential for malignant transformation. While they can manifest in various organs, cases involving the hands are exceptionally rare. Hamartomas in the hand have been documented sparingly. To date, there have been no cases of hamartomas in the fingers, hence contributing to the limited body of literature. This case report discusses a hamartoma in the right little finger of an 80-year-old male with a history of a slowly growing painless mass over the course of 5 years. Examination revealed a 1x1 mass with benign features over the proximal interphalangeal joint (PIPJ). A plain radiograph was unremarkable. An excision biopsy was done, and histopathological examination (HPE) revealed a diagnosis of hamartoma. Post-operatively, his wound healed accordingly, and normal function of the finger was achieved.
