background: tumor markers are substances, which quantitatively changes in serum, during the tumor development, one such tumor marker is serum β2-microglobulin (β2-m). the aim of this study was to establish the role of β2-m as a biochemical parameter for diagnosis and prognosis of oral carcinoma by estimation of serum β2-m levels in potentially malignant lesions, conditions, and oral squamous ce...

introduction: granular cell tumors (gcts) are rare and mostly benign soft tissue tumors. though they have been reported in all parts of body, they are generally located in the head and neck region, especially on the tongue. some malign forms exist, but these have been rarely reported. granular cell tumors have a neural origin and, in immunohistochemical evaluations, they express s-100 and neuro...

This report is related to a female 7-year-old crossbreed sheep whose right eye had been protruded andswelling of upper eyelid was observed. Routine enucleating was performed. Histopathological evaluation ofeyelid revealed coincidence of two kinds of neoplasms. The first part was composed of multiple lobules ofsebocytes, which were detected as meibomian adenoma. The second section included infil...

background: although color doppler ultrasonography (cdus) is useful in the diagnosis of various diseases of the head and neck, flow signals in oral malignant masses are less studied; hence the present study assesses the usefulness of color doppler ultrasonography in quantifying oral squamous cell carcinoma (oscc) vascularization. in addition, we determine the hemodynamic parameters by spectral ...

A rare case of squamous cell carcinoma of the breast is presented. A 50 year-old female patient suffered from a painful tumor of the right breast 8 years prior to death. The histology of the resected mammary tumour revealed squamous cell carcinoma with an adenocarcinomatous feature in the minority. Malignancy developed in the left lung 5 years after the surgery and formed a huge mass including ...

background: oral squamous cell carcinoma is the sixth most common malignancy in the world today.  ing1b/p33 is a newly-discovered tumor suppressor which enhances p53 activity. transfer of p33 protein from nucleus to cytoplasmic compartment has been previously reported in leukemias. the objective of this study was to determine the correlation between p33ing1b cytoplasmic transfer and lymph node ...

human papillomavirus (hpv) dna has been identified in esophageal carcinomas. however, the incidence of hpv varies significantly in different geographical locations. in this study, neoplasms from turkmen sahra, a region in golestan province in northeast part of iran, with a high incidence of squamous cell carcinoma were analyzed for the presence of hpv dna. turkmen sahra is located in the cancer...

INTRODUCTION Malignant transformation is a rare complication of mature cystic teratoma, with squamous cell carcinoma as the most common malignancy (in 75% of cases). In this article we present a case of a well-differentiated squamous cell carcinoma arising in a mature cystic teratoma and discuss the morphological and clinico-pathological features of malignant transformation in teratoma. CASE ...

Introduction: Although cervical carcinoma is common, cutaneous metastasis from this tumor is rare. The reported incidence rates of skin metastasis from cervical cancer range from 0.1% to 1.3%. The major histological subtype of cervical carcinoma is squamous cell carcinoma (SCC), accounting for 75% of cases. The remainder are classified as adenocarcinoma, adenosquamous cell carcinoma, or are of ...

introduction: her2/neu, a member of the epidermal growth factor receptor family, has been shown to be over-expressed in some tumors. the purpose of this study was to determine the salivary levels and tissue expression of her2/neu in patients with head and neck squamous cell carcinoma (hnscc) and their correlation with clinicopathologic parameters.   materials and methods: enzyme-linked immunoso...
