In 2016, the WHO classification of testicular germ cell tumors was revised considering advances in the understanding of their tumorigenesis and molecular features. This restructuring led to a division into two major groups with, on one hand, prepubertal-type tumors, not derived from germ cell neoplasia in situ (GCNIS), and on the other hand, postpubertal-type tumors, GCNIS-derived, which occur in youg men (seminoma and non seminomatous germ cell tumors - embryonal carcinoma, yolk sac tumor, teratoma and choriocarcinoma essentially). The term germ cell neoplasia in situ is consensually accepted as a new terminology for the precursor lesion. Read More

Resection of a mature cystic teratoma of the liver harboring a carcinoid tumor.

J Surg Case Rep 2018 Oct 31;2018(10):rjy279. Epub 2018 Oct 31.

St. Vincent Hospital Indianapolis, Department of Hematology/Oncology, Indianapolis, IN, USA.

Cystic teratomas are rare pluripotent embryonic tumors which most commonly originate in gonadal organs. Extra-gonadal cystic teratomas are exceedingly uncommon, accounting for only 1% of all cystic teratomas, and have been reported in unusual locations including the kidney, mediastinum and liver. These extra-ovarian cystic teratomas have also been known to harbor other neoplasms including carcinoid tumors. Read More

Unusual Radiographic Presentation of Intracranial Mature Teratoma and Resection via Supraorbital Approach.

World Neurosurg 2019 Feb 25;122:81-84. Epub 2018 Oct 25.

Department of Surgery, Division of Plastic Surgery, University of Washington Medical Center, Seattle, Washington, USA; Craniofacial, Plastic Surgery, Oral and Maxillofacial Surgery, Seattle Children's Hospital, Seattle, Washington, USA.

Background: Primary intracranial teratomas account for <1% of intracranial masses during childhood after infancy. When supratentorial, they commonly occur in the pineal and suprasellar regions, demonstrating multilocularity, areas of fat, and calcifications and increasing enhancement correlating with decreased maturity. However, the presence of a teratoma as a mobile fat lesion within a large unilocular suprasellar cyst is rarely documented in this patient population. Read More

Unexpected False-positive I-131 Uptake in Patients with Differentiated Thyroid Carcinoma

Mol Imaging Radionucl Ther 2018 Oct;27(3):99-106

Ege University Faculty of Medicine, Department of Nuclear Medicine, İzmir, Turkey

Objective: Radioiodine is the most specific radionuclide for differentiated thyroid carcinoma (DTC) imaging. Despite its high specificity and sensitivity, false-positive I-131 uptake could be seen on whole body scan (WBS) that may lead to misdiagnosis and unnecessary radioiodine treatment. In this study, we aimed to present the I-131 WBS and concomitant single photon emission computed tomography/computed tomography (SPECT/CT) images of unexpected false-positive radioiodine uptake along with the patients’ clinical outcomes and the contribution of SPECT/CT imaging.
