BMJ Case Rep 2020 Dec 13;13(12). Epub 2020 Dec 13.

Imperial College Healthcare NHS Trust, London, UK.

A man in his mid 70s was referred to head and neck outpatients with bulky tissue in the left tonsillar fossa. He had previously been treated for oligometastatic renal clear cell carcinoma (diagnosed over 15 years prior to disease recurrence) by tonsillectomy and adjuvant radiotherapy (years from primary treatment), followed by trans-oral laser surgery to his oropharyngeal recurrence 3 years later. Examination under anaesthetic and biopsy confirmed further recurrence of disease in the left tonsillar fossa, with parapharyngeal extension, which has not been previously reported in the literature.

The Many Uses of p53 Immunohistochemistry in Gynecological Pathology: Proceedings of the ISGyP Companion Society Session at the 2020 USCAP Annual9 Meeting.

Int J Gynecol Pathol 2021 Jan;40(1):32-40

Department of Pathology, University of Calgary, Calgary, Alberta, Canada.

Ancillary immunohistochemistry (IHC) has become a reliable adjunct for subclassification of gynecological neoplasms. An important recent development was optimization and validation of p53 IHC, where 3 abnormal IHC patterns (nuclear overexpression, complete absence, cytoplasmic) were shown to predict underlying TP53 mutations with high accuracy in ovarian carcinomas. p53 IHC now helps in distinguishing high-grade serous from low-grade serous carcinomas.

Department of Pathology, Guangdong Provincial People's Hospital/Guangdong Academy of Medical Sciences, Guangzhou 510080, China.

To investigate the optimal experimental conditions (including antigen retrieval time, antibody titers and antibody incubation time) for reliable detection of programmed death-ligand 1 (PD-L1) expression using PD-L1 (22C3) antibody concentrate, and to establish a laboratory developed test for PD-L1 detection. Using Dako PD-L1 IHC 22C3 pharmDX staining procedure and scoring guidelines as the standard reference (group A), the PD-L1 expression in 25 tissue specimens (including 15 lung cancer tissues, 5 tonsil tissues and 5 placenta tissues) was detected with Flex+/HRP detection kit (EnVision) under 8 different experimental conditions (groups B1 to B8). The staining results were then compared to those in group A. Read More

PLoS Pathog 2020 10 19;16(10):e1008968. Epub 2020 Oct 19.

School of Pharmacy, Chapman University, Irvine, California, United States of America.

Despite 25 years of research, the basic virology of Kaposi Sarcoma Herpesviruses (KSHV) in B lymphocytes remains poorly understood. This study seeks to fill critical gaps in our understanding by characterizing the B lymphocyte lineage-specific tropism of KSHV. Here, we use lymphocytes derived from 40 human tonsil specimens to determine the B lymphocyte lineages targeted by KSHV early during de novo infection in our ex vivo model system. Read More

Improved cancer detection in Waldeyer's tonsillar ring by Ga-FAPI PET/CT imaging.

Eur J Nucl Med Mol Imaging 2021 04 15;48(4):1178-1187. Epub 2020 Oct 15.

Department of Otorhinolaryngology, Plastic, Aesthetic and Reconstructive Head and Neck Surgery, Julius Maximilian University of Wuerzburg, 97080, Wuerzburg, Germany.

Purpose: In cancer of unknown primary (CUP), positron emission tomography/computed tomography (PET/CT) with the glucose analog [F]FDG represents the standard imaging approach for localization of the malignant primary. Frequently, however, [F]FDG PET/CT cannot precisely distinguish between small occult tumors and chronic inflammation, especially in Waldeyer's tonsillar ring. To improve the accuracy for detecting primary tumors in the Waldeyer's tonsillar ring, the novel PET tracer [Ga]Ga-FAPI-4 for specific imaging of fibroblast activation protein (FAP) expression was used as a more specific target for cancer imaging.

Department of Surgery, Saint Agnes Hospital, Baltimore, USA.

Metastasis of extra-intestinal carcinoma to the gastrointestinal tract (GIT) is a rare event, most commonly occurring with malignant melanoma. Anti-PD-1 (programmed death-1) immunotherapeutic agents are immune checkpoint inhibitors with proven benefit across multiple cancer types, including squamous cell carcinoma of the head and neck (SCCHN). Here we describe a case of small bowel perforation attributed to a primary SCCHN metastasizing to the GIT in the setting of treatment with PD-1 inhibitors. Read More
