Pyocolpos: A rare cause of recurrent abdominal pain - Always insist on a thorough physical examination.

Thorough physical examination is a must for proper diagnosis of medical diseases and to elucidate all physical findings. Abdominal pain is a very common presentation to Emergency Department, compromising 5%-10% of all visits, and around a quarter are discharged with no particular diagnosis. Pyocolpos is one of those presentations that requires a thorough physical examination, including that of the external genitalia. A 3-year-old girl presented with recurrent history of abdominal pain and a recent history of fever with acute abdomen picture-like presentation, with difficulty voiding over the past few days. She was previously assessed for recurrent abdominal pain, without any identifiable etiology. Upon inspection for indwelling catheter insertion, absence of the vaginal introitus was noted with a bulging mass and an imperforate hymen. Pyocolpos was diagnosed and drained following hymenotomy. Pyocolpos is a rare complication of hydrocolpos. Enlarged vagina causes extrinsic compression to nearby structures, such as the bladder trigone and ureters, causing hydronephrosis, hydroureter, and other sequel including acute kidney injury and urosepsis. An imperforate hymen must be considered in the differential for chronic and recurrent abdominal pain, and can be easily identified by a thorough physical examination, including that of the external genitalia, which is a must in today's every medical practice.
