erally, involvement of the surgical margin by tumor cells on histopathologic examination is an indication to repeated surgical resection with wider margins, especially in immunosuppressed patients. In summary, we described a 56year-old patient with liver transplantation who developed aggressive conjunctival squamous cell carcinoma that invaded the brain and led to death despite orbital exentera...

skin cancer is one of the most important type of cancers in the world. in this way, molecular investigation in order to detect some novel mechanisms and polymorphisms involved in cancer development can be impressive and vital. in this way, the aim of this study was the histopathological investigation of skin cancer and its relationship with polymorphism of cdkn2a gene. this case-control study w...

a primary intraosseous carcinoma (pioc) is a squamous cell carcinoma arising within the  jawbone andshould be differentiated from a malignant ameloblastoma.  it  is not due to arising from an odontogenic cyst or tumor. the possibility of the lesion being  a metastasis fromanotherprimary site should be considered, and excluded by a careful history and examination. the diagnosis of a pioc is rare...

primary de novo intraosseous carcinoma is a rare neoplastic lesion which commonly occurs in the jaws. it is an epithelial odontogenic malignancy arising from odontogenic epithelial residues in the bone rather than from a preexisting epithelial lesion. in the present case report, the clinical, radiological and histological features of primary de novo intraosseous carcinoma are discussed and its ...

Keratoacanthoma generally occurs on the skin; it is rarely found in the conjunctiva. A case of a 34-year-old woman with a rapidly growing conjunctival mass is reported. The tumor was excised with a safety margin to exclude squamous cell carcinoma. Histopathologically it was crateriform and consistent with atypical keratoacanthoma. There has been no recurrence in 2 years of follow-up. Conjunctiv...

background & objectives:  cd10 is a cell surface enzyme with metalloendopeptidase activity, also known as common acute lymphoblastic leukaemia antigen, which mainly serves as a marker for acute lymphoblastic leukemia (all). to date and to the best of our knowledge, only few comparative immunohistochemical studies have assessed cd10 expression in cutaneous epithelial neoplasms. our goal was ...

zinc has an important role in skin health and its deficiency reduces immunity. to evaluate levels of zinc in squamous cell carcinoma (scc) and basal cell carcinoma (bcc) of skin, we studied 44 bcc and 38 scc cases together with 33 controls. blood samples were taken and after separation of serum, levels of zinc, albumin and total protein were measured by atomic absorption, albumin kit and reflec...

background and aims. there is no report on the apoptotic impact of allium sativum l. (garlic) on the oral squamous cell carcinoma (kb); hence, this study was designed to survey the apoptotic effects of garlic fresh juice (gfj) on the kb cells. materials and methods. mtt assay (microculture tetrazolium assay) was carried out to evaluate the cytotoxicity of gfj on kb cells. furthermore, tunel (te...
