Ovarian dermoid cyst with atypical juvenile presentation: case report

Abstract

Germ cell tumors are a diverse group of neoplasms that make up around 20% to 25% of all ovarian tumors. These tumors mainly affect young individuals and make up most of the tumors found in children. The occurrence of mature cystic teratomas is low, ranging from 1.2 to 14.2 cases per 100,000 people per year, and they are typically discovered incidentally.

Clinical case. The case of a 17-year-old female patient, nulliparous, nulliparous, without sexual life, without comorbidities, presented conservative adnexal tumor surgery in 2017 for right ovarian teratoma without complications. A new mass is identified approximately 21x15x10cm left annex. Tumor extraction surgery was performed, histologically resulting in a mature cystic teratoma, a tumor measuring 19 cm in greatest diameter with an intact capsule, and an edematous and congestive salpinx. The incidental findings of the presence of this type of neoplasms are of interest in our patients, given that the incidence of neoplasms at younger ages is a reality. Our patient had a history of a previous contralateral smaller teratoma with benign histology. and presents de novo with an adnexal mass of exaggerated proportions that takes the classic characteristics of the mature dermoid cyst out of context. In this case, since there is no intraoperative study to diagnose benignity or malignancy, conservative surgery of the affected gonad is not performed due to the risk. uncertain whether it is a strain with a high risk of malignant transformation.
