Solid organ transplant recipients have a high incidence of cutaneous squamous cell carcinoma and often develop multiple and aggressive tumours. This retrospective study based on the Swedish organ transplant cohort, focuses on the deaths caused by cutaneous squamous cell carcinoma and aims to elucidate the clinicopathological features of these tumours. The cohort comprised 5931 patients who underwent organ transplantation during the period 1970 to 1997 and were registered in the Swedish In-patient Registry, Cancer Registry and Causes-of-Death Registry. A total of 544 cutaneous squamous cell carcinomas in 201 patients were re-examined. The dominating size of the tumours was 5–10 mm and one-third of the tumours were removed by methods other than excision surgery. Well-differentiated tumours and Clark level IV were predominant. Seven patients died from their tumours, all of which were localized on the head. The principal site of metastasis was the parotid gland. The mean duration between date of transplantation and death was 10.4 years (range 6–17 years). Mortality from cutaneous cell carcinoma was compared with that of the general population. There was a highly increased risk; standardized mortality ratio 52.2; 95% confidence interval 21.0–107.6. However, the mortality rate in the Swedish cohort appears to be lower than what has been reported previously from other countries.
