A huge abdomino-pelvis tumour in a prepubertal girl: A case report of dysgerminoma infiltrating both ovaries and uterus in an 11-year-old girl in Maiduguri

Dysgerminoma is one of the rare highly malignant ovarian germ cell tumour. It originate from undifferentiated germ cells that are similar to primordial germ cells, and it is identical to testicular seminoma in males. Despite the tumour being malignant, prognosis is excellent with surgery and adjuvant chemotherapy, with promising results concerning future fertility. In this case, we report an 11-year-old girl with abdominal swelling for 7 years. She had gross abdominal distension, with a huge palpable mass. Abdominopelvic ultrasound scan showed a huge heterogeneous mass measured 9.8 cm x 15.7 cm and computed tomography showed a huge lobulated mass measured 19.2 cm x 19.0 cm x 16.3 cm. Exploratory laparotomy and excision of the mass was done. Ovarian dysgerminoma are uncommon in prepubertal girls. Prognosis depends on the stage at presentation and histology. Multidisciplinary management with a Gynaecologists and Oncologists with joint decision on the need to maintain the child’s developmental and reproductive potential as much as possible should aimed at.
