Summary
Scars and foreign bodies
Epithelial tumors and fibrous scarring
Carcinomas arise in relation to scar formation as observed in schistosomiasis and asbestosis, but it is not clear to what extent the scar formation per se actually contributes to these tumors. Several reports suggest that squamous cell carcinoma of the skin may arise as a complication of chronic ulcers, chronic inflammatory skin diseases, burns and scars or even a single injury. Traditionally this complication has been reported mainly in dark-skinned populations from Africa and Asia (Camain et al., 1972; Mulay, 1963), but has also been described in black Americans (Fleming et al., 1975; Keith et al., 1980). Case reports suggest that skin cancer occasionally complicates the scars of chronic skin diseases such as tuberculosis, leprosy, syphilis and discoid lupus (Keith et al., 1980). Both basocellular carcinoma and dermatofibroma have been reported to develop in a smallpox vaccination scar (Ribeiro et al., 1988).
In India, kangri cancer occurs in burn scars in the lower abdomen and thighs of people who use baskets (kangri) containing clay pots with burning charcoal to warm their bodies in winter (Mulay, 1963).
Soft tissue sarcomas (STS)
Foreign bodies
In rodents, the experimental transplant of a membrane, irrespective of its chemical nature, e.g. glass coverslip or plastic sheet, leads frequently to capsule formation followed by a soft tissue sarcoma.
