[Xanthogranuloma juvenile (McDonagh disease) in a 4-month-old infant]

A rare case is presented of xanthogranuloma juvenile (McDonagh disease) in a four-month-old infant. The diagnosis was based on a characteristic appearance of skin rash, good general condition, absence of changes in laboratory investigations and typical histological pattern. In the differential diagnosis other conditions with similar skin lesions were considered (xanthoma tuberosum, eruptivum, disseminatum and planum).
