Marjolin's ulcers are a rare form of malignancy that present at regions exposed to chronic infection. They present with a clinical triad of nodularity, induration, and ulceration greater than 3 months. We present herein, an extremely rare case of Marjolin's ulcer of the forearm, secondary to osteomyelitis, resulting from a 30-year neglection of external fixator used to treat a war injury of the forearm. Marjolin's ulcers are classically encountered in lower extremities at sites of burns, trauma or complicated wounds.
