Mature solid teratoma of the uterine cervix: A rare case report and review of the literature

Rationale:Most of the mature teratomas are found in the ovaries. Extragonadal teratomas are extremely rare. To date, there are only a handful of reports of uterine cervical teratomas documented in the English literature.Patient concerns:Herein we describe a rare case of a 40-year-old patient who was presented to our hospital for a cervical polypoid mass, which was finally confirmed to be mature solid teratoma in uterine cervix.Diagnoses:Histological examination of the polypoid mass was found to consist of ciliated pseudostratified columnar respiratory epithelium, intestinal epithelium and smooth muscle tissue, adipose tissue and mature glial component, epidermis, and skin adnexa. Meanwhile, no history of abortion, dilatation, and curettage was present in this patient, so implantation of fetal tissue was excluded. Therefore, we make a diagnosis of uterine cervical mature teratoma.Interventions:Tumorectomy was performed after discovering the cervical polypoid mass.Outcomes:The patient had been followed-up for next 3 months after surgery and no recurrence was documented until now.Lessons:Though teratomas of the uterine cervix are extremely rare, more attention should be paid on this rare but possible tumor for appropriate treatment in these patients.
