Marjolin's ulcer revisited--basal cell carcinoma arising from grenade fragments? Case report and review of the literature.

Abstract

Marjolin's ulcer is a rare and often aggressive cutaneous malignancy arising in previously traumatized or chronically inflamed skin. A 79-year-old World War II veteran developed basal cell carcinoma (BCC) at the site of a war wound. The tumour developed in relation to several metal grenade fragments. With a disease-free interval of 61 years between injury and onset of complications the patient had one of the longest latency periods of tumour development described so far. Review of the literature reveals only five cases of relation between grenade fragments and malignancy formation. Presence of foreign bodies has been described as possible aetiology for malignancy development. Explosives and additives contain several mutagenic and tumourigenic substances. We hypothesize a causal connection between the grenade fragments and the development of BCC. Considering the long period of latency between injury and tumour development we suggest grenade injury with left fragments in soft tissue to be a new origin of Marjolin's ulcer.
