Abdominal and gonadal mature cystic teratomas

open access: yesJournal of Pediatric Surgery Case Reports, 2022
The estimated incidence of germ cell tumours (GCT), is approximately 0.9/100,000 population [1,2]. One type of germ cell tumour, known as a teratoma, is typically derived from primordial germ cells, which have the potential to differentiate into somatic cells [3].
