METHODS
A cross-sectional study including 42 women with facial melasma, conducted at the Dermatology Service of Botucatu Medical School of São
BACKGROUND
Melasma is a commonly acquired symmetrical hypermelanosis on sun-exposed areas of the skin. The development of melasma appears to be associated with increased levels of oestrogen, exposure to sunlight and a genetic predisposition. Several in vitro studies have partially clarified the
Melasma is an acquired hypermelanosis that typically affects sun-exposed areas on the face and presents as symmetric brownish macules and patches. It is most commonly reported in women and thought to be related to the effects of estrogen and progesterone on melanocytes. Since the advent of

Melasma is a specific type of facial hyperpigmentation seen in women taking oral contraceptives, in non-pregnant women who have not used oral contraceptives, and in some pregnant women during the progression of gestation, but rarely in men. Circulating LH, FSH, PRL, and E2-17 beta on day 5, 7, 9,
BACKGROUND
Knowledge of the histopathology of melasma is a prerequisite for understanding its pathogenesis. However, the histopathological characteristics of male melasma are not well characterized.
OBJECTIVE
We sought to investigate the histopathological characteristics of melasma in men compared
BACKGROUND
Melasma is relatively uncommon in males, and there is a paucity of data on male melasma, including its clinical pattern, triggering factors, endocrine profile and histopathological findings.
OBJECTIVE
To characterize the clinical findings and aetiological factors, including hormonal and
Melasma is localized hyperpigmentation over the forehead, upper lips, cheeks, and chin. In this study, evidence suggesting an association between autoimmune thyroid disorders and melasma and the relationship of thyroid disorders to the origin of melasma is presented. A total of 108 nonpregnant
