A Case of Congenital Constricting Band of the Trunk / 대한피부과학회지

ABSTRACT

Congenital constricting band of the trunk is a rare malformation with a wide spectrum of associated congenital anomalies. A 3-year-old boy with a congenital constricting band around the waist and anterior thigh and clubfoot deformity is reported. Laboratory test and chest and abdominal X-ray examination were within normal limits and unremarkable. Histopathologic examination revealed compact fibrocollagenous bundles in deep dermis. The compact fibrocollagenous bundles are parallel to the skin surface and have thin wavy nuclei. We think these bundles caused annular constriction on the trunk. We follow up the patient regularly without specific treatment because the constricting band caused no functional impairment and hypertrophic scar had developed at the biopsy site.
