Ovine squamous cell carcinoma(OSCC) is a naturally occurring malignant tumour, being considered due to solar radiation. The literature on OSCC is reviewed, pertaining to the following five aspects of the disease; aetiology, tumour development, geographica

I had treated a patient, 58 years old male, with squamous cell carcinoma in mandible. In the patient, radical operation was made by hemimandiblectomy, neck dissection and gnathoplasty with resin made mandible. The patient was radically treated, and the results were excellent in point of view of mandibular functions and esthetics.

A 26 year-old Korean woman was visited to Chunnam University Hospital on January 15, 1971 with chief complaints of facial nerve paralysis, hearing impairment, painful swelling on the temporal region and aural discharge. The histopathological Examination proved to be a squamous cell carcinoma.

A ten-year-old holstein cow was presented because of prolapse of the third eyelid and apparent hyperplasia of the right lower eyelid. Historical findings included increased appetite as well as polyuria and polydipsia for about two weeks. The most remarkable fadings on physical examination were a large periocular proliferative tissue and bleeding. Surgical incision was used both as a biopsy and therapeutic tool in holstein cow with mass. Histopathological examination of the mass revealed squamous cell carcinoma. Blood and milk tests of patient with squamous cell carcinomatosis were peformed, but normal values.

Oral squamous cell carcinoma (OSCC), which accounts for approximately 90% of oral cancers, has a high rate of local recurrence and a poor prognosis despite improvements in treatment. Exosomes released from OSCC cells promote cell proliferation and metastasis. Although it is clear that the biogenesis of exosomes is mediated by the endosomal sorting complex required for transport (ESCRT) machinery, the gene expression pattern of ESCRT, depending on the cell type, remains elusive. The exosomal release from the human OSCC cell lines, HSC-3 and HSC-4, and their corresponding gefitinib-resistant sub-cell lines, HSC-3/GR and HSC-4/GR, was assessed by western blot and flow cytometry. The levels of ESCRT machinery proteins, including Hrs, Tsg101, and Alix, and whole-cell ubiquitination were evaluated by western blot. We observed that the basal level of exosomal release was higher in HSC-3/GR and HSC-4/GR cells than in HSC-3 and HSC-4 cells, respectively. Long-term gefitinib exposure of each cell line and its corresponding gefitinib-resistant sub-cell line differentially induced the expression of the ESCRT machinery. Furthermore, whole-cell ubiquitination and autophagic flux were shown to be increased in gefitinib-treated HSC-3 and HSC-4 cells. Our data indicate that the expression patterns of the ESCRT machinery genes are differentially regulated by the characteristics of cells, such as intracellular energy metabolism. Therefore, the expression patterns of the ESCRT machinery should be considered as a key factor to improve the treatment strategy for OSCC.

Squamous cell carcinoma (SCC) arising within the lining of an odontogenic keratocyst (OKC) is a rare occurrence. Although potentially locally destructive, OKC is a benign odontogenic process that typically presents with clinical and radiographic features characteristic of a benign intraosseous neoplasm. We present the clinical and radiographic features of a maxillary mass that demonstrated SCC arising from the lining of an OKC. Although the initial clinical and radiographic presentation suggested an infection or malignant neoplasm, biopsies revealed an infiltrative well-differentiated SCC contiguous with and arising from the focus of a pre-existing OKC. The patient subsequently underwent a type II hemi-maxillectomy with neoadjuvant chemoradiation. This report discusses the clinical and radiographic features associated with intraosseous malignancies, especially those arising from an otherwise benign odontogenic lesion. While the majority of OKCs are benign, the current report illustrates the potential for carcinomatous transformation within the lining of an OKC.

In order to search for anticancer agent as therapy of oral squamous cell carcinoma (OSCC) and malignant pleural mesothelioma (MPM) from Korean traditional prescriptions, we selected 58 traditional prescriptions based on a review of the Korean traditional medicine books. Among the selected traditional prescriptions, only water extracts of paedoksan (敗毒散) showed relatively good cytotoxicity at the concentration of $50{\mu}g/ml$. Additionally, we evaluated cytotoxicity for various paedoksans and each herbal ingredient in paedoksans. The root of Anthriscus sylvestris exhibited more cytotoxic effect than any other ingredients in paedoksans. Bioactivity-guided fractionation of the MC layer of Anthriscus sylvestris led to the isolation of deoxypodophyllotoxin (DPT). DPT exhibited dose-dependently significant cytotoxicity against OSCC and MPM cell with nM range. Therefore, DPT from A. sylvestris might be a potential candidate as an effective anticancer therapeutic agent for OSCC and MPM.

Background: Skin cancer is the most common type of cancer worldwide. It has an increasing trend. This study investigated the epidemiological trend and morphological changes in skin cancer in Iran. Materials and Methods: This study was done using existing data, extracted from the National Cancer Registry System and the Disease Management Center of Iranian Ministry of Health between 2003 and 2008. Data on epidemiologic trend was analyzed using Joinpoint software package. Results: The incidence of skin cancer is increasing in Iran, and more in men than women. There was a declining trend for basal cell carcinoma. Basal squamous cell carcinoma and melanoma had an increasing trend. The increase of skin cancer was related to squamous cell carcinoma. Conclusions: Our findings indicated that the increase of skin cancer was attributed to squamous cell carcinoma. It is necessary to be planning for the control and prevention of this disease as a priority for health policy makers.

Synchronous primary lung cancers in the same lobe are rare. Cavitating adenocarcinoma as single lung lesion is unusual. We experienced cavitating adenocarcinoma and squamous cell carcinoma in the same lobe of the lung. The patient was a 74-year-old male with chief complaints of hemoptysis. CT scan showd a central mass in right upper lobar bronchus, obstructive pneumonia, and lung abscess in the right upper lobe. Pathologically, the central mass was a 2.3$\times$1$\times$1 cm sized squamous cell carcinoma, and lung abscess was revealed as a 37272 cm sized adenocarcinoma. The patient was discharged without any specific problem after right peumonectomy.
