Summary
Lipofibromatous hamartoma, a rare benign tumor, caused acquired macrodactyly and median nerve issues in a 61-year-old. Diagnosis was confirmed via imaging, revealing fatty infiltration of the median nerve.
Area of Science:
- Orthopedic Surgery
- Neurology
- Pathology
Background:
- Lipofibromatous hamartoma is a rare, benign tumor often misdiagnosed.
- It typically presents in childhood but can manifest later in life.
Observation:
- A 61-year-old patient presented with acquired, painful macrodactyly of the left thumb and median nerve paresthesia.
- Clinical examination revealed a wrist tumefaction.
- A history of forefinger amputation for macrodactyly without diagnosis was noted.
Findings:
- Radiographs showed hypertrophic bone structures.
- Ultrasound revealed a hypertrophic left median nerve with fatty infiltration.
- Retrospective analysis of prior exams suggested lipofibromatous hamartoma in the amputated index finger.
Implications:
- This case highlights the potential for late diagnosis of lipofibromatous hamartoma.
- It underscores the association between lipofibromatous hamartoma, macrodactyly, and median nerve compromise.
- The controversial nature of treatment for this rare pathology warrants further investigation.
