A sinus tract that becomes malignant is known as?

A chronic sinus tract that becomes malignant is called a Marjolin ulcer. This term refers to squamous cell carcinoma arising in long-standing wounds, scars, or sinus tracts—most classically from burn scars or chronic osteomyelitic fistulas. The transformation typically occurs after many years of ongoing irritation and poor vascularity in scar tissue, and the resulting lesion often presents as a non-healing ulcer within a scar with indurated margins, sometimes with foul discharge or bleeding. While the cancer is usually squamous cell carcinoma, the defining feature is its origin in a chronic inflammatory environment. Other terms listed describe non-malignant aspects of osteomyelitis (like involucrum or cloaca) or a general cancer type, rather than this specific malignant transformation setting.
