Abstract
Background: The clinical and histopathological characteristics of acquired bilateral
nevus of Ota‑like macules in men are poorly documented due to its rarity. Aims: To
compare the clinical and histopathological characteristics of acquired bilateral nevus of
Ota‑like macules in men with the condition in women. Methods: We studied 11 men and
62 women, all with a clinical diagnosis of acquired bilateral nevus of Ota‑like macules.
Biopsies were taken from 5 men and 10 women and their clinical and histopathological
features were compared. Results: The most frequently affected site in men was the
forehead [8 (73%) out of 11 patients]. Lesions on the forehead were more common in
men than women (P = 0.001). In contrast to women, there was no apparent tendency of
the lesions to become more blue with age in men. Concurrent melasma was observed in
14 (23%) out of 62 women, but not in men. Extra‑facial acquired dermal melanocytosis
was noted in 2 (18%) out of 11 men and in none of the 62 women. Conclusion: Significant
differences were noted between men and women in the appearance of concurrent
pigmentary lesions and the distribution of lesions. Extra‑facial acquired dermal
melanocytosis was noted in men.
