Squamous cell carcinoma arising from teratoma of the ovary: magnetic resonance, computed tomography, and pathological findings.

: In the present case report, the authors investigated the clinicopathological characteristics of squamous cell carcinoma (SCC) arising from teratoma of the ovary and intended to report their clinical experience. Malignant transformation of ovarian teratoma is a quite rare condition with SCC observed to be the most common form of transformation. The present case was a 43-year-old female patient and her clinical presentation was abdominal pain, abdominal distension, and abdominal mass sensation. The patient underwent ultrasonography. After detection of a mass, magnetic resonance imaging (MRI) was performed. Surgery was performed on the patient and the pathological report revealed SCC arising from teratoma. The patient was evaluated retrospectively in terms of demographic characteristics, MRI, surgical findings, and prognosis.
