Distribution of skin type and skin cancer in organ transplant recipients.

moved owing to a clinical suspicion of malignancy, we collected the clinical differential diagnoses for all pigmented lesions biopsied. We defined clinically suspect lesions as those for which the study dermatologist’s differential diagnosis indicated melanoma and/or dysplastic nevus on the pathology requisition form. In this way, lesions removed for cosmetic purposes were excluded from the BMR. Statistical Analysis. The BMR for each year was determined by dividing the total number of clinically suspect, histologically proven benign pigmented lesions (including dysplastic nevi, common nevi, seborrheic keratoses, solar lentigines, lichen planus–like keratosis, and pigmented actinic keratoses) by the total number of histologically proven melanomas.
