BACKGROUND: Psoriasis is a chronic inflammatory skin disease with an incidence of 1-3%. Psoriasis usually occurs in the scalp, knee, elbow, sacral region and joints. The nipple-areola complex involvement is rarely encountered in the literature. CASE REPORT: 31-year-old female patient, who presented at the dermatology outpatient clinic with a lesion characterized by bright, pearlescent-white squamous lesions on an erythematous plaque, limited to the nipple-areola complex for the past three years, and who was diagnosed with “Psoriasis” following incisional biopsy. CONCLUSIONS: The benign or malignant distinction should be made for lesions observed in the nipple-areola complex. It should not be forgotten that psoriasis may also be present in the differential diagnosis of dermatitis-like benign lesions that do not respond to long-term and various drug treatment, although they are rare.
