A Rare Case Of Retroperitoneal Mature Cystic Teratoma In A Young Male Patient

ABSTRACT

Retroperitoneal mature cystic teratomas are exceedingly uncommon in young male. They are more common in infants and in young females. We report an unusual case of 27 year old male presented with abdominal distension, abdominal fullness and vomiting. Patient underwent ultrasonography and contrast enhanced computed tomography (CT) scan of abdomen which were suggestive of large mature cystic lesion. Patient was planned for surgery and laprotomy was done. A huge retroperitoneal mass was observed and was totally excised. Onhisto-pathological examination (HPE) stratified squamous epithelium with keratin flakes, underlying fibromuscular tissue reveal hair shaft & sebaceous glands and mature cystic teratomawas diagnosed. Retroperitoneal mature cystic teratoma in an older maleis extremely rare. Primary gonadal teratoma with retroperitoneal metastasis should be excluded first. Evaluation of age and location of tumor are critical for its prognosis.
