Three patients with solitary lesions of capillary aneurysm are reported. There does not seem to be an association with previous excessive solar and/or x-radiation, complexion, antecedent acne, or trauma.
Capillary aneurysms are clinically indistinguishable from early, uncomplicated malignant melanomas. In the absence of histopathologic or compelling clinical evidence that the lesion is malignant, the treatment of a black melanoma-like nodule should consist of total but conservative excision. Subsequent tissue examination should then indicate whether or not more radical surgery is required.
