Pediatric hand masses are often seen in outpatient department of the hospital. There are kinds of masses that can occur and it is important to discriminate between malignant and benign, since the treatment may be different. Calcifying aponeurotic fibroma (CAF) is a rare benign soft tissue in children and adolescents. It primarily occurs on the distal portion of the extremities, typically fingers, palms of the hands and plantar aspects of the feet. The recommended treatment of CAF is conservative local excision. Considering its benign characteristics and the rare metastasis, a strong and enough efforts should be made, whenever possible, to preserve the function of involved extremities, especially in child. In our report, we present a case of a 4-year-old girl with a CAF found near the course of motor branch of ulnar nerve at the palm and being performed surgical removal successfully with preserving the nerves.
