Ectopic pancreatic tissue at the umbilicus in childhood: a case report and review of the literature.

ABSTRACT

Ectopic pancreatic tissue at the umbilicus is very rare. To our best knowledge, only fourteen cases of ectopic pancreatic tissue at the umbilicus are reported. In this paper we present the case of a two-year-old boy with an abrasion at the umbilicus. He had a poorly healing scar that started bleeding after recurrent injuries. Abdominal ultrasound revealed an unclear cystic structure with no communication to intra-abdominal structures. Surgical resection was performed without complications. Histology diagnosed an ectopic pancreatic tissue with reactive epidermal changes. We present a review of the literature and the clinical manifestations and treatment of the previously reported fourteen cases.
