Abstract Purpose Prostatic tissue in an ovarian teratoma is an unusual finding, whose initiation in a 46, XX karyotype tissue is yet to be clarified. We present a case from our files and review the literature for this intriguing finding. Methods Unstained histology sections of the ovarian teratoma containing prostatic tissue were evaluated using immunohistochemistry for PSA and androgen receptor. Results Both PSA and androgen receptor immunostainings were positive in the prostatic tissue. From the literature review, it appears that most of the patients (74%) with similar findings were either pregnant or experiencing a miscarriage, menopausal or infertile at presentation, showing that an imbalanced hormone status is frequently associated with the presence of male structures in ovarian teratomas.

Pneumatosis cystoides-like pattern is a group of histopathological features occasionally found in ovarian teratomas. This is a case of laparoscopic ovarian cystectomy performed for incomplete adnexal torsion where histology reported mature ovarian teratoma with “pneumatosis cystoides-like appearance”. This term is used to describe the presence of multiple cystic spaces within the tumor wall. It has been reported also in other organs, such as gastrointestinal tract, urinary bladder and the vagina. It may be secondary to mechanical, bacterial or ischemic causes, with the pathogenesis remaining unclear. It is benign and may exist more often than reported.

Ovarian Teratomas

Mature cystic teratoma is the most common kind of ovarian germ cell tumor. Malignant transformation is uncommon, with thyroid cancer rarely found. Papillary thyroid microcarcinoma has rarely been described as associated with ovarian teratomas. We report a case of a 34-year-old woman who presented with abdominal pain and an ovarian mass. After surgery, the patient was diagnosed with a follicular variant papillary thyroid microcarcinoma that arose within a mature cystic ovarian teratoma. Based on the small size of the primary lesion and patient preferences, no further treatment was performed. To our knowledge, this is the third reported case of papillary thyroid microcarcinoma arising within a mature ovarian teratoma without struma ovarii. There is no consensus on the surgical approach and postoperative management of this condition. Whether further therapy with total thyroidectomy and radioiodine ablation may be beneficial is unknown. In conclusion, papillary thyroid microcarcinoma can also arise within mature ovarian teratomas. Although a favorable prognosis is anticipated, there is limited information about its history or prognosis.

This article aims to explore the problem of anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis and also describes our own experience in treating anti-NMDAR encephalitis in patients with ovarian teratomas. This pathological condition is a rare complication of cancer. Practicing gynecologists are often unfamiliar with it, although its consequences can be life-threatening. Early diagnosis and causal treatment, particularly teratoma removal, are critical for the outcome and can prevent death or the development of neurological deficits in patients.
