We report the clinical features and long‐term follow‐up of 20 pediatric patients with parakeratosis pustulosa (PKP). In eight children PKP was considered as a clinical manifestation of psoriasis. Of these, three children had skin psoriasis at the time of our observation, two developed nail psoriasis, and three developed psoriatic pitting during follow‐up. Parakeratosis pustulosa was considered a symptom of allergic contact dermatitis in four patients, whereas atopic dermatitis was possibly responsible for PKP in two patients. A complete recovery from disease was observed in 11 patients. The results of our study suggest that PKP is not a single entity but rather represents a nail symptom that can be produced by several inflammatory diseases, including nail psoriasis, atopic dermatitis, and contact dermatitis.
