Giant Median Nerve Due to Hamartoma Causing Severe Carpal Tunnel Syndrome

Introduction: Lipofibromatous hamartoma (LFH) is a very rare, benign, slow-growing peripheral nerve tumor. Case Report: We present a case of LFH of the median nerve, which caused enlargement of the median nerve and the digital branches in a young male, and was treated surgically. Our treatment choice was resection of large portions of the fibrofatty tissue and decompression of the carpal tunnel. Conclusion: A high index of suspicion for LFH is crucial in patients presenting with painless masses combined with acute compression neuropathy.
