BACKGROUND: The development of squamous cell carcinomas is the main cause of death of patients with Dystrophic epidermolysis bullosa. We think it is of interest to know their clinical characteristics and the treatment difficulties they cause. METHODS: We followed the clinical evolutions and carried out histopathological studies of eight primary cutaneous squamous cell carcinomas on three males and one female with recessive dystrophic epidermolysis bullosa. Patient ages ranged from 16 to 34 years (mean 27). RESULTS: Two patients had two tumours and one three, all were in characteristically scarred skin; four on upper limbs; four on lower. Maximum tumour dimensions ranged from 2 to 28 cm (mean 13), and represented 6 or more months of evolution. In three cases the affected limb must be amputated. Five tumours were well differentiated, three were moderately differentiated. CONCLUSIONS: The patients consulted too late and their large lesions needed aggressive treatment. Appropriate information and regular examination of patients with RDEB helps early diagnosis of tumours and may avoid disabling operations.
