Immature ovarian teratoma (IOT) is a rare and aggressive malignant neoplasm characterized by immature neural tissue. The cytomorphologic features have only rarely been described. We herein describe an additional case and review the literature regarding this entity. To the best of our knowledge, this is the first reported case with imprint cytology. A 35‐year‐old woman presented with a pelvic mass which was resected and sent for frozen section evaluation. Imprint smears and frozen section of the… 

Usefulness of Intraoperative Imprint Cytology in Ovarian Germ Cell Tumors

TLDR
It is demonstrated that intraoperative assessment based on imprint cytology for immature teratoma has a relatively lower sensitivity, but an acceptable sensitivity for other germ cell tumors.

Metastatic of mature component in a treated case of immature teratoma diagnosed on fine‐needle aspiration cytology of the liver

TLDR
A case of immature teratoma that presented with isolated liver metastasis and was confirmed in FNAC from the liver as metastasis of mature elements, which is an uncommon tumor comprising of <1% of teratomas of ovary.

Intraoperative Cytology of Ovarian Neoplasms with an Attempt to Grade Epithelial Tumors

TLDR
IOC gives comparable results to frozen section and can be used for intraoperative assessment of ovarian tumors and may become an important step in intraoperative decision-making for better management and outcome of the patient.

Cytologic Distinctive Features of Brenner Tumor

TLDR
Evaluating the cytologic features of Brenner tumor will aid in improving the accuracy and efficiency of the differential diagnosis of ovarian tumors during intraoperative consultation.

Distinctive Features of Brenner Tumor

TLDR
Evaluating the cytologic features of Brenner tumor will aid in improving the accuracy and efficiency of the differential diagnosis of ovarian tumors during intraoperative consultation.

FNA biopsy of small round cell tumors of childhood: Cytomorphologic features and the role of ancillary studies

TLDR
FNA cytology ofSRCTs of childhood can be diagnostic in the majority of cases, allowing specific therapy to be given to patients with unresectable SRCTs without a tissue biopsy as well as documenting recurrent and/or metastatic disease.

Cytomorphologic features of immature ovarian teratoma in peritoneal effusion: A case report

TLDR
This is the first description of the cytologic features of non‐neuroepithelial elements in the ascitic fluid in a patient with immature ovarian teratoma, a 26‐yr‐old woman with a huge pelvic mass.

Ovarian Neoplasms Composed of Small Round Cells: A Review

TLDR
The morphologic features of some of the ovarian small cell neoplasms are described, as is the value of immunohistochemistry and other ancillary techniques in establishing a diagnosis.

Immature teratoma of the ovary on fluid cytology

TLDR
The presence of immunohistochemical‐confirmed glial tissue on the cell block preparation confirmed the diagnosis of an immature ovarian teratoma in the peritoneal fluid of a 10‐yr‐old girl who presented with a pelvic mass.

Peripheral primitive neuroectodermal tumor of the ovary confirmed by CD99 immunostaining, karyotypic analysis, and RT-PCR for EWS/FLI-1 chimeric mRNA.

TLDR
Results confirmed the diagnostic validity of the present tumor being a pPNET, thus raising the possibility that in the past, pP NETs which have arisen in the ovary may have been mistakenly diagnosed as small cell carcinomas of the Ovary.

Pure cystic nephroblastoma of the ovary with a review of extrarenal Wilms' tumors.

TLDR
A second case of pure ovarian extrarenal Wilms' tumor (EWT) is presented and plaques of alpha-inhibin positive cells were detected that corresponded to foci of peripheral stromal luteinization in an ectopic location.

Germ cell tumors of the gonads: a selective review emphasizing problems in differential diagnosis, newly appreciated, and controversial issues

TLDR
As expected, teratomas in boys are clinically benign, whereas in postpubertal males they are malignant, independent of their degree of immaturity, and the judicious use of tailored panels of immunohistochemical stains resolve these dilemmas in virtually all instances.

Immature (malignant) teratoma of the ovary. A clinical and pathologic study of 58 cases

TLDR
The size and stage of teratomas were related to survival, but it was the grade of the primary tumor that best determined the likelihood of extraovarian spread, and it was not the size or stage of the metastases that related best to the subsequent course.
