Objective: To present a case of specialized ovarian teratoma and a review of the published literature on the epidemiology and the diagnostic characteristics of this tumor, emphasizing the histopathological diagnosis. Materials and methods: A 50 year-old female patient who was seen because a pelvic mass at the ESE Clínica Maternidad Rafael Calvo, level II referral center in the Department of Bolívar that serves patients of the rural areas and low socioeconomic levels.

The histopathology of the right-sided tumor showed multiple follicular thyroid structures with colloid content, resulting in a diagnosis of Struma Ovarii. A search of the literature was conducted in Medline via Pubmend, from 1996 to this date. Additional searches were conducted in Hinari, Imbiomed, and Ebsco using the terms “Struma Ovarii”, “Ovary”, “Struma”, “Monodermal teratoma”, “Bilateral teratoma”, published in English or Spanish and dealing with the epidemiology and the histopathological diagnosis. Results: Overall, 450 published articles were found and, of those, 27 relating to struma ovarii and bilateral teratomas were reviewed.

Conclusions: Struma ovarii is a specialized variant of ovarian teratomas, and signs and symptoms such as hyperthyroidism and the associated presence of a pelvic mass may suggest the diagnosis. Diagnostic tests include ultrasound and axial tomography, which may help with differentiation and diagnosis. Histopathological criteria play a crucial role in the final diagnosis.
