Giant serous adenofibroma of the fallopian tube

Serous adenofibroma of the fallopian tube is a rare, benign tumour of the female genital tract. They are usually small, asymptomatic and incidentally diagnosed during a surgery for another gynaecological condition. This report presents an atypical case of a 17-year-old girl with a tubal serous adenofibroma that presented with a palpable mass occupying the entire abdomen accompanied by urinary symptoms. She underwent a laparoscopic surgery with drainage of 1800mL of yellow, citrine liquid from the cyst and left salpingectomy with no complications.
