Primary gastric squamous cell carcinoma (SCC) is a rare histological subtype of gastric cancer. Here, we report the first case of primary gastric verrucous carcinoma (VC), a well-differentiated variant of SCC. Gastroscopy revealed a papillary polypoid lesion at the posterior wall of the upper gastric body and isolated squamous epithelium at the greater curvature of the fornix in a 78-year-old woman.

Verrucous carcinoma (VC) is a rare variant of well differentiated squamous cell carcinoma (SCC) which is usually found in oral cavity mucosa. Cutaneous verrucous carcinoma is a rare entity and in this paper we report a 43 years old man with VCsuperimposed on chronically inflamed skin of ileostomy site. Previously, he was operated to treat rectal adenocarcinoma and has had ileostomy for six months. Read More

Human papillomaviruses (HPVs) are causative of a group of clinically papillary lesions. The HPV-related lesions of the oral cavity include squamous papilloma, condyloma acuminatum, verruca vulgaris, and multifocal epithelial hyperplasia. Benign entities, such as verruciform xanthoma or giant cell fibroma, as well as malignancies, such as papillary squamous cell carcinoma and verrucous carcinoma, may be considered in the clinical and/or histologic differential diagnoses of these lesions.

Verrucous hyperkeratosis (VH), verrucous carcinoma (VC) and the relentless, truly pre-malignant variant proliferative verrucous leukoplakia often exhibit lichenoid histologic features that may create a diagnostic dilemma for pathologists. This study aims to evaluate and categorize the frequency and the histopathologic patterns of lichenoid features seen in these lesions. Following IRB approval, cases of VH and VC from 1994 to 2014 were retrieved from the archives of UF Oral Pathology Biopsy Service. Read More

Tongue squamous cell carcinoma is one of the most commonly diagnosed intraoral squamous cell carcinomas (25-40%), being considered an aggressive form of squamous cell carcinoma, as it is most commonly associated with lymph node metastases and the survival rate at five years is below 50%. In according with these data, we have proposed in this study to individualize an epidemiological and histopathological profile of the patients with such oral cancers, diagnosed and treated in the Oral and Maxillofacial Surgery Clinic and in the Otolaryngology Surgery Clinic of the Emergency Clinical County Hospital Craiova, between 2015-2017. The cases were histopathologically reassessed according to the latest WHO classification of head and neck tumors, the variables of interest being the age of the patients, the gender, the lesion topography, the histological subtype, the degree of tumor differentiation, the pTNM stage, the resection margin status and the Brandwein-Gensler prognostic score.

Purpose: Oral carcinoma cuniculatum is a rare well-differentiated variant of oral squamous cell carcinoma. The purpose was to systematically review its unique features to differentiate it from other variants as verrucous carcinoma, papillary squamous cell carcinoma and well-differentiated squamous cell carcinoma.

Materials And Methods: A systematic review was performed using MEDLINE, Dentistry and Oral Sciences Source and PubMed databases and any existing articles related to the research subject missed in the search strategy to screen ones reporting cases occurring exclusively in the oral cavity in English literature.

Non-urothelial carcinomas involving the bladder are uncommon and often diagnostically challenging. These carcinomas may show squamous, adenocarcinomatous or neuroendocrine features, with immunohistochemical stains aiding the diagnosis in only a subset of cases. The clinical history in non-urothelial bladder carcinomas is important, given that the differential diagnosis often includes secondary involvement of the bladder by direct extension or metastasis from carcinomas at other sites.

Part 2 of this 2-part continuing medical education series discusses the clinical and histopathologic features of common premalignant and malignant lesions of the oral cavity. It is imperative for dermatologists to be able to recognize suspicious lesions, determine biopsy need, counsel, and refer patients presenting with premalignant or malignant conditions appropriately. Given the higher rates of mortality and morbidity of oral mucosal malignancies due to late diagnosis, appropriate treatment with multidisciplinary care in a timely manner is essential to these neoplasms.

Verrucous carcinoma of the esophagus (VCE) is a rare variant of squamous cell cancer, with a puzzling clinical, etiological, and molecular profile. The etiological involvement of human papillomavirus (HPV) in the cancer's natural history is controversial. This study considers nine cases of VCE, focusing on patients' clinical history before surgery, histological phenotype, immunophenotype (EGFR, E-cadherin, cyclin D1, p16, and p53 expression), HPV infection, and TP53 gene mutational status (exons 5-8).

Context: - Histologic distinction between condyloma acuminatum and various benign and malignant condyloma-like lesions in the anogenital area poses a common diagnostic challenge to pathologists across subspecialties.

Objective: - To review the overlapping and distinguishing features of condyloma acuminatum and its mimics, and to clarify confusing terminology and diagnostic criteria for problematic entities.

Data Sources: - A review of the literature on condyloma acuminatum (ordinary and giant types), verrucous carcinoma, warty/warty-basaloid high-grade squamous intraepithelial lesion and squamous cell carcinoma, papillary squamous cell carcinoma, bowenoid papulosis, verruca vulgaris, epidermolytic acanthoma, and verruciform xanthoma was performed.

Introduction: Human papilloma virus (HPV) is the most common sexually transmitted pathogen and its potential role in the genesis of several diseases such as cervical, head and neck, anal and penile cancers, is now largely recognized. Aim of this review article was to evaluate and summarize the state of the art of HPV-related urogenital cancers, focusing on the potentially innovative methods for the diagnosis of infection that should be used to improve viral causative detection and prevent its diffusion through sexual intercourses.

Evidence Acquisition: The initial search was carried out by using the Medline and the Google Scholar computerized databases through the selected key-words to identify the more recent literature on HPV epidemiology and its relationship with the main relevant urinary tract cancers. Read More

Human papillomavirus (HPV) has long been proposed as a cofactor in the pathogenesis of cutaneous squamous cell carcinoma (cSCC). More recently, the striking clinico-pathological features of cSCCs that complicate treatment of metastatic melanoma with inhibitors targeting BRAF mutations (BRAFi) has prompted speculation concerning a pathogenic role for oncogenic viruses. Here, we investigate HPV and human polyomaviruses (HPyV) and correlate with clinical, histologic, and genetic features in BRAFi-associated cSCC. Read More

Background: The PTEN-hamartoma-tumor-syndrome (PHTS) is caused by germline mutations in Phosphatase and Tensin homolog (PTEN) and predisposes to the development of several typical malignancies. Whereas PTEN mutations have been implicated in the occurrence of malignant mesotheliomas, the genetic landscape of verrucous carcinomas (VC) is largely uncharted. Both VC and malignant peritoneal mesotheliomas (MPM) are exceedingly rare and a potential link between these malignancies and PHTS has never been reported. Read More

Background: Verrucous carcinoma (VC) should be considered a distinct clinicopathologic entity different from the more common oral squamous cell carcinoma (OSCC) because of its unique biological behavior. Best way to understand the behavior of these carcinomas is to study them by means of molecular methods, especially in tumor progression tests and Bcl-X is an important antiapoptotic member of the Bcl-2 family and is one of the newest and most useful markers to determine the aggressiveness of many carcinomas. The relationship between this Bcl-X protein and carcinomatous behavior toward it is not studied extensively, which we attempted to evaluate using immunohistochemical analysis in selected carcinomas of the head and neck region.
