Case Report: Scar contracture caused by ruptured subcutaneous ganglion cyst misdiagnosed as Dupuytren's disease: diagnostic reflections on a rare case.

This study reports a case of scar contracture on the volar side of the left little finger secondary to ruptured ganglion cyst in a 26-year-old female patient, which was misdiagnosed as Dupuytren's disease. The patient had a medical history of Hodgkin's lymphoma and received bleomycin chemotherapy, which may have accelerated the fibrotic process. Intraoperative findings were inconsistent with the preoperative diagnosis, and the final diagnosis was confirmed by pathological examination. Complete surgical resection successfully relieved the contracture. This case suggests that the etiology of subcutaneous scar contracture is complex. Comprehensive evaluation combined with patient medical history, medication history and pathological results is essential to achieve accurate diagnosis.
