Choroidal Metastasis Secondary to Testicular Mature Teratoma: A Case Report.

Ocul Oncol Pathol 2021 Mar 4;7(2):85-90. Epub 2021 Jan 4.

Sheffield Ocular Oncology Service, Department of Ophthalmology, Sheffield Teaching Hospitals, Sheffield, United Kingdom.

We report a case of a choroidal metastasis secondary to testicular mature teratoma, a subtype of non-seminoma germ cell tumours, in a young adult male. The choroidal metastasis was treated successfully with bleomycin, etoposide, and cisplatin chemotherapy without the need for adjuvant radiotherapy. This represents a rare case of mature teratoma metastasizing to the choroid and one of very few reported testicular germ cell tumours to achieve normal or near normal visual acuity with chemotherapy alone despite severe macular disease at presentation.

Dataset of testicular germ cell tumors (TGCT) risk associated with serum polychlorinated biphenyl (PCB) by age at diagnosis and histologic types.

Data Brief 2021 Jun 27;36:107014. Epub 2021 Mar 27.

School of Public Health, Brown University, Providence, RI 02903, USA.

In a population-based case control study of testicular germ cell tumors (TGCT), we reported a strong positive association between serum levels of Wolff's Group 1 (potentially estrogenic) polychlorinated biphenyl (PCBs) and risk of TGCT, and the observed associations were similar for both seminoma and non-seminoma. While the observed specific associations between TGCT and Wolff's Group 1 PCBs cannot be easily explained by bias or confounding, a question can still be asked, that is, could the relationship between PCBs and TGCT differ by age at diagnosis? PCBs tend to bioaccumulate, with more heavily chlorinated PCB congeners tending to have longer half-lives. Half-lives of PCB congeners were reported ranging from 4. Read More

Paraneoplastic Neurological Syndromes and Beyond Emerging With the Introduction of Immune Checkpoint Inhibitor Cancer Immunotherapy.

Front Neurol 2021 9;12:642800. Epub 2021 Apr 9.

Departments of Neurology and Laboratory Medicine and Pathology, Mayo Clinic College of Medicine, Rochester, MN, United States.

Paraneoplastic neurological syndromes are more commonly seen with malignancies such as small cell lung cancer, thymoma, gynecological malignancies, and breast cancer as well as seminoma. With the introduction of immune checkpoint inhibitor (ICI) cancer immunotherapy we see an increase of autoimmune neurological complications in patients with malignancies not traditionally associated with paraneoplastic neurological syndromes, such as melanoma and renal cell carcinoma. Immune checkpoint inhibitors enhance antitumor immune responses resulting often in immune-related adverse effects that can affect any organ, including the central and peripheral nervous system, neuromuscular junction and muscle.
