Umbilical Sebaceous Cyst Mimicking Infected Urachal Sinus

摘要

In addition to the most likely diagnoses for umbilical signs in adults (umbilical hernia, metastatic tumour, endometriosis, congenital abnormalities such as umbilical-urachal sinus and gallstones retained or spilled at the umbilicus), the differential diagnosis should also include epidermoid cyst arising from the skin of the umbilicus.We describe the case of a young man who presented with a persistent umbilical discharge which was initially thought to be umbilical-urachal sinus, but later found to be a sebaceous cyst.
