Hello there...I can understand your concern. Black skin in the thighs can be due to many reasons like tinea cruris infection, post inflammatory hyperpigmentation, steroid creams abuse, acanthosis nigricans, erythrasma, idiopathic(that is some people will normally also have black pigmentation in the groin, axilla). You will need detailed clinical examination and if needed even skin biopsy. So kindly consult a dermatologist for further evaluation.
