Malignant melanoma is the most common cancer during pregnancy, but it is unknown whether melanocytic naevi in general are activated. A total of 381 melanocytic naevi in 34 Caucasian primigravidae were examined using spectrophotometric intracutaneous analysis (SIAscopy) technology in early pregnancy and prior to delivery. The Siagraphs of each naevus were then compared in order to evaluate chang...

BACKGROUND It is unclear which of the number or the density of naevi on the skin is the more appropriate measure of risk of melanoma. Furthermore, the relationship between the number of naevi and their density in an individual has not been explored. Thus, for example, it is unknown if larger people tend to have more naevi by virtue of having a larger skin area, or if the density of naevi is sim...

THE naevus of Ota is characterized by benign mesodermal melanosis of the skin of the face with pigmentation of the eye and its adnexa. It is probably more familiar to the dermatologists. Pusey (1916) was the first to describe the association of scleral and facial pigmentation in a young Chinese student.
