[Investigation of malignant melanoma in an "open house" setting]

Individuals with a self-evaluated risk of malignant melanoma were invited to an "open house" where trained dermatologists examined suspected lesions. The attendants filled in a short questionnaire relating to skin cancer risk factors. Persons with skin changes suspected for malignancy were referred for excision in the dermatological department. The clinical evaluation included dermatoscopy. Nine hundred and eleven individuals attended. Among 16 individuals referred for excision one malignant melanoma, one lentigo maligna melanoma and two in situ melanomas were histologically verified. Furthermore, 21 basal cell carcinomas were identified clinically. The most frequent clinical diagnoses were melanocytic naevi and seborrhoic keratoses.
