Histological and immunohistochemical investigation of canine prostate carcinoma with identification of common intraductal carcinoma component.

Vet Comp Oncol 2021 May 7. Epub 2021 May 7.

University of Nottingham, BioDiscovery Institute, Nottingham, UK.

A limited number of species, including men and dogs, spontaneously develop prostate cancer (PC). The histological and molecular relevance of canine PC as a model for the disease in men remains controversial. To address this challenge, this study aimed to assess the histomorphology and expression of basal cell, urothelial and neuroendocrine markers [p63, high molecular weight cytokeratin (HMWCK), Uroplakin 3 (UPIII), neuron-specific enolase (NSE)] in canine PC (n=41).

Differential Diagnosis and Management on Seborrheic Keratosis in Elderly Patients.

Clin Cosmet Investig Dermatol 2021 28;14:395-406. Epub 2021 Apr 28.

Dermatology Unit, University of Campania, Naples, Italy.

Seborrheic keratoses are exceedingly common in the elderly and usually are easy to diagnose and do not require treatment. However, given their great variety of clinical presentation, they may give rise to false-positive cases, meaning that they may at times mimic melanoma, squamous cell carcinoma and basal cell carcinoma. On the other hand, melanoma may mimic seborrheic keratosis, leading to incorrect patient management. Read More

Identification and characterization of primary cilia-positive salivary gland tumours exhibiting basaloid/myoepithelial differentiation.

J Pathol 2021 Apr 30. Epub 2021 Apr 30.

Department of Tumor Pathology, Hamamatsu University School of Medicine, Hamamatsu, Japan.

Primary cilia (PC) are non-motile, antenna-like structures on the cell surface. Many types of neoplasms exhibit PC loss, whereas in some neoplasms PC are retained and involved in tumourigenesis. To elucidate the PC status and characteristics of major salivary gland tumours (SGTs), we examined 100 major SGTs encompassing eight histopathological types by immunohistochemical analysis.

Aberrant epithelial polarity cues drive the development of precancerous airway lesions.

Proc Natl Acad Sci U S A 2021 May;118(18)

Department of Biochemistry, Boston University School of Medicine, Boston, MA 02118;

Molecular events that drive the development of precancerous lesions in the bronchial epithelium, which are precursors of lung squamous cell carcinoma (LUSC), are poorly understood. We demonstrate that disruption of epithelial cellular polarity, via the conditional deletion of the apical determinant Crumbs3 (Crb3), initiates and sustains precancerous airway pathology. The loss of Crb3 in adult luminal airway epithelium promotes the uncontrolled activation of the transcriptional regulators YAP and TAZ, which stimulate intrinsic signals that promote epithelial cell plasticity and paracrine signals that induce basal-like cell growth.

Pan-TRK Immunohistochemistry Is Highly Correlated With NTRK3 Gene Rearrangements in Salivary Gland Tumors.

Am J Surg Pathol 2021 Apr 23. Epub 2021 Apr 23.

Department of Pathology, Centre Henri Becquerel INSERM 1245, Rouen Normandy Uniiversity Department of Pathology, Rouen University Hospital, Rouen Platform of Experimental Pathology, Department of Diagnostic and Theranostic Medicine, Curie Institute Department of Pathology, Lariboisière Hospital, Paris, France.

Aims: Secretory carcinoma (SC) is characterized by ETV6 rearrangements, most often ETV6-NTRK3 fusion. Given its histologic overlap with other salivary gland tumors (SGTs), SCs can be difficult to diagnose without genetic confirmation. A recently developed pan-TRK (tropomyosin receptor kinase) antibody shows promise for identifying tumors with NTRK (neurotrophic tyrosine kinase receptor 3) fusions. Read More

Basal Cell Nevus Syndrome with Unusual Associated Findings: A Case Report with 17 Years of Follow-Up.

Am J Case Rep 2021 Apr 22;22:e928670. Epub 2021 Apr 22.

School of Dentistry, Federal University of Pará (UFPA), Belém, PA, Brazil.

BACKGROUND Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin-Goltz syndrome (GGS), is an inherited autosomal dominant disorder caused by mutations in the patched (PTCH) tumor-suppressor gene, which has high penetrance and variable phenotypic expressivity. In 1960, Gorlin and Goltz defined the condition by 3 main characteristics: multiple basal cell carcinomas, odontogenic keratocyst (OKC), and skeletal anomalies. Nowadays, many neurologic, ophthalmic, endocrine, and genital manifestations are known to be associated with this syndrome. Read More

Tissue Expression of Carbonic Anhydrase IX Correlates to More Aggressive Phenotype of Basal Cell Carcinoma.

Front Oncol 2021 25;11:659332. Epub 2021 Mar 25.

Pathology Unit, Department of Advanced Biomedical Sciences, University of Naples "Federico II", Naples, Italy.

Basal cell carcinoma (BCC) is the most common cancer in the white-skinned population accounting for about 15% of all neoplasms. Its incidence is increasing worldwide, at a rate of about 10% per year. BCC, although infrequently metastasizing, very often causes extensive tissue losses, due to the high propensity toward stromal infiltration, particularly in its dedifferentiated forms, with disfiguring and debilitating results.

Nuclear factor IB is downregulated in vulvar squamous cell carcinoma (VSCC): Unravelling differentially expressed genes in VSCC through gene expression dataset analysis.

Oncol Lett 2021 May 16;21(5):381. Epub 2021 Mar 16.

Department of Pathology, Erasmus MC, University Medical Center Rotterdam, 3000CA Rotterdam, The Netherlands.

Vulvar squamous cell carcinoma (VSCC) comprises two distinct etiopathological subtypes: i) Human papilloma virus (HPV)-related VSCC, which arises via the precursor high grade squamous intraepithelial lesion (HSIL); and ii) HPV-independent VSCC, which arises via precursor, differentiated vulvar intraepithelial neoplasia (dVIN), driven by mutations. However, the mechanism of carcinogenesis of VSCC is poorly understood. The current study aimed to gain insight into VSCC carcinogenesis by identifying differentially expressed genes (DEGs) for each VSCC subtype. Read More
