If a patient suddenly notices significant hyperpigmentation in the armpits and the roots of the thighs, it is important to look at the situation differently. In some cases, this is due to hormone levels and genetics. In some cases, when pregnant women are close to giving birth, they may develop hyperpigmentation, such as in the armpits, lower pubic area, and nipples, and the pigmentation may fade as the pregnancy ends. There are also localized cases of significant hyperpigmentation due to hormonal stimulation during puberty, which is a normal condition and not a disease. However, other patients may have dark coloring in the armpits, and the root of the thighs, accompanied by significant itching and skin peeling, flaking, must take the time to go to the regular tertiary care hospital dermatology department, to rule out whether the fungal infection caused.
