Thrico-rhino-falangeal syndrome is a rare disease characterized by a bulbous nose, sparse hairs, a long flat philtrum, and epiphyseal coning. We describe here in a 15 year old girl with Thrico-rhino-falangeal syndrome type 1 (TRPS I). Physical examination demonstrated bulbous nose, hair abnormalities, deformity of the phalanges and winged scapulae. Genetic study and radiologic findings confirmed the diagnosis. Thrico-rhino-falangeal syndrome is characterized by musculoskeletal deformities that at the first view may simulate juvenile idiopathic arthritis. These musculoskeletal deformities could imply the differential diagnosis with juvenile idiopathic arthritis.
