Do So

Cutaneous horn has been a source of controversy throughout the history. It evoked interest nearly half a millennium before and continues to do so. Cornu cutaneum has been found to be associated with several pre-malignant and malignant skin conditions. The pre-malignant conditions commonly include actinic keratoses and Bowen’s disease. Uncommonly, it is due to the presence of an underlying squamous cell carcinoma. Thus, an effort is needed to determine the pathology present at the base of the horn for proper management of the disease. Wide excision biopsy is a common denominator in the therapy of this peculiar disorder.

This report outlines the treatment of an 82-year-old man with squamous cell carcinoma of the left cheek. The wide excision and simultaneous superficial parotidectomy were planned. Various incision methods have been widely introduced such as retroauricular hairline incision, modified Blair incision, or face-lift incision. For coverage of preauricular skin defect and parotidectomy, we modified retroauricular hairline incision that the end of the incision was bent to make transposition flap. The operation has been successfully finished using this extension of a retroauricular hairline incision.

Squamous cell carcinoma of the mammary gland is rare in both veterinary and human medicine. Whereas human metaplastic and squamous variants are known, the objectives of the current study were to ascertain the presence of such entities in canine mammary tumors and to distinguish them from other (epidermal, sweat gland) squamous tumors that may develop in the same area. A panel of antibodies (anticytokeratin [CK] 19, CK 14, CK 5/6, pancytokeratin, and vimentin) was used on 18 mammary gland malignancies with squamous features and 16 malignant skin tumors (11 squamous cell carcinomas of the skin and 5 sweat glands). Fifteen of the 18 mammary carcinomas were classified as metaplastic carcinomas, and the remaining 3 were classified as squamous cell carcinomas. The 2 most useful markers to establish the histogenesis of mammary tumors were pancytokeratin and CK 19. All other antibodies were equally expressed (CK 14 and 5/6) in all histotypes. The antibody panel discriminated primary epidermal squamous tumors (pancytokeratin positive and CK 19 negative) from gland-derived squamous neoplasms (pancytokeratin positive and CK 19 positive) but failed to distinguish primary mammary tumors from other squamous tumors of glandular origin.

Submandibular Region

Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck region. They are also called branchial cysts and occur due to lymphocyte induced cystic ductular dilatation. The confirmatory diagnosis is always made on histopathological examination after resection. A 29 years old female patient presented to ENT department, Pt B. D. Sharma PGIMS, Rohtak with a soft to firm, non-tender, swelling in the submandibular region since 2 -3 days and was referred to Department of Pathology for FNAC on which a differential diagnosis of infected epidermoid cyst or squamous cell carcinoma was made and excision biopsy for confirmation and categorization was advised. The swelling was then excised and sent for histopathological examination and a final diagnosis of Lymphoepithelial cyst was made. The confirmatory diagnosis is always made postoperatively by histopathological examination. The treatment of a lymphoepithelial cyst is the surgical approach, which includes complete enucleation of the cyst. This is a case report of a lymphoepithelial cyst diagnosed on histopathology specimen for which differential of Infected cyst or Squamous cell carcinoma was given. The authors intend to highlight the importance of early histopathological diagnosis of Benign LEC as it has been reported to undergo malignant transformation

Oncogenic Virus

The most common kind of oral cancer is known to be the epithelial cells cancer. The disease develops under the influence of many factors. Extensive studies confirms relationship of the occurrence of cancer in the mouth area and infection with oncogenic virus. Papilloma virus (HPV) and Ebstein-Barr (EBV) are considerate to be the most potent oncogenic viruses. Aim. The aim of the studies was to present the role of the oncogenic virus in the development of squamous cell of oral cancer. Materials and methods. Literature was carried out from November 2014 to January 2018 period using „Pub-Med”, MEDLINE, SCOPUS with keywords: squamous cell carcinoma of the Oral Cavity, oncogenic factors in squamous cell in oral carcinoma, oncogenic virus, role of Ebstein-Barr virus in the development of squamous cell of oral carcinoma, role of human papillomavirus in the development of squamous cell carcinoma. Results. To the review 16 publications were qualified that meet certain criteria for good literature. Identification of comparative characteristics was aimed at finding a common denominator of research results. Discussion. In the review the focus point was on the role of factors which is oncogenic virus. Analysis of the available data has confirmed that more and more frequent cause of commonly known factors such as tobacco smoke, alcohol, neglect hygiene, and genetic factor became undoubtedly the role of virus factor. Summary. High incidence of cancers has led to the search for relevant etiological factors in the development carcinoma process, especially in and around oral cavity. Knowledge of the most cancerogenic factors is important in order to prevent, and the search of effective treatments. In addition, the cited publications, draws attention to the fact the use of saliva as research material. This throws a new light on the work of dentists and the possibility of their involvement in the process of tumor detection and the initiating factor of oncogenesis.
