A previously healthy nine-month-old boy presented to the Emergency Department with a two-week history of rash that started in the diaper area and later extended to the trunk, limbs and face. The mother reported a family history of psoriasis. The child had multiple erythematous papules and plaques on the face, trunk, diaper area, and limbs. He was diagnosed with guttate and napkin psoriasis and started on topical treatment, with good response. Psoriasis is a chronic condition that can manifest clinically at any stage of life. In pediatric age, the presence of a positive family history is common and guttate or napkin psoriasis are typical clinical presentations. Sometimes, napkin psoriasis rapidly progresses to a more widespread form, typically involving the face. The diagnosis is clinical and must be differentiated from other common causes of exanthema and diaper rash in infants.
