A fatal case of metastatic squamous cell carcinoma in a patient with myositis ossificans traumatica.

Myositis ossificans traumatica is a rare disease associated with chronic wounds and fistulae. Chronic ulcers, fistulae and wounds can transform into squamous cell carcinoma, the so-called Marjolin's ulcer. We describe a rapid, progressive and fulminant course of a metastatic squamous cell carcinoma arising from a chronic wound in a patient with myositis ossificans traumatica.
