Medial antebrachial cutaneous neuropathy: a case report.

Medial antebrachial cutaneous (MABC) neuropathy in the forearm is rare. We report here a case of this neuropathy after surgery for panniculitis excision. Examination revealed hypesthesia over left medial forearm at MABC nerve territory. Tineal's sign at the operation site of left medial arm was positive. Sensory nerve conduction studies showed reduced sensory nerve action potential amplitude which is compatible with an axonal neuropathy and interside amplitude ratio of 2.35. In the present case report, the sensory nerve conduction study is a useful tool in confirming MABC neuropathy.
