Seborrhoeic dermatitis may also affect the inguinal fold and the skin of the scrotum. Differentiation from fungal infection is aided by the absence of an active border and commonly found fissuring, which is rare in fungal infection. Other areas of the skin (scalp, face, presternal area, mid-back) are also affected quite often. Topical corticoids of low potency or topical ketoconazole are therapeutic alternatives.
