Mucoepidermoid carcinoma is a rare conjunctival neoplasm that is a common malignancy in the salivary glands. In the conjunctiva it often mimics squamous cell carcinoma. Histologically the tumors are believed to arise from pluripotential basal cells and, possibly, mucussecreting elements, and therefore are composed of mucus-secreting cells intermixed with epidermoid cells. The clear cell variant...

Since the 1980s, the number of patients presenting with squamous cell carcinoma of the conjunctiva has been increasing exponentially. 1,2 In ophthalmic outpatient clinics in Harare, at least two of every one hundred patients have squamous cell carcinoma. The patients vary in age from eighteen to sixty years with the majority between twenty and forty years. Both males and females are affected. O...

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 ...

ocular surface may be involved by different neoplastic lesions ranging from benign to highly malignant. recognition of risk factors, clinical presentations, pathology, and different therapeutic modalities is essential for selecting an appropriate approach. this article deals with the proper approach to ocular surface squamous neoplasia (ossn) including conjunctival/corneal intraepithelial neopl...

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...
