Psoriasis vulgaris (PsV) is a chronic inflammatory skin disease associated to genetic and environmental factors. We report two cases of a family with three generations affected with this pathology. The propositus (a three-year-old boy), his father and his grand-father present confluent erythematous plaques with scales and their diagnostic of PsV was made based on the clinical characteristics and supported by histopathological study. More than 50% of the body is covered by lesions. The propositus received treatment as hydrocortisone and emollients reflected a slight positive response; however his father has had multiple treatments without significant improvement.
