ABSTRACT
Jejunal teratoma (JT) is a rare type of extragonadal teratoma. To date, the subject of mature jejunal teratomas has not yet been discussed in the literature. This type of teratoma contains cystic, solid, and calcified components. JT may be suspected on a computed tomography (CT) scan, whichcan describe the various features of the germinal layer components, followed by normal laboratory results of alpha feto protein (AFP) and ß-human chorionic gonadotropin (ß- hCG). This case report describes that of a teenager with a mature JT whose chief complaints were recurrent general weakness due to anemia and an abdominal mass. The patient was initially treated with non-operative management; however, his symptoms remained unresolved, and he accepted surgical intervention. No additional chemotherapy or radiotherapy was required after complete tumor excision. The patient no longer complained of general weakness following surgery.
