Papillary Squamous Cell Carcinoma: A Rare Variant of Oral Squamous Cell Carcinoma

Squamous Cell Differentiation in Metastatic Papillary Thyroid Carcinoma: Metaplastic

Squamous cell differentiation (SCD) may occur in papillary thyroid carcinoma (PTC) only at metastatic sites. We have studied cytokeratin CK5/6 and P63 along with TTF1 (thyroid transcription factor 1)  and B-Raf (V-Raf murine sarcoma viral oncogene homolog B1) immunohistochemical expression in neck lymph node metastases of thyroid PTC showing SCD. The patient (21-years) presented wit...

Tongue Squamous Cell Carcinoma: A Clinical Study

  Background and Objectives: Squamous cell carcinoma of the tongue (SCCOT) is the most common malignant neoplasm in oral cavity. At the time of the diagnosis of SCCOT regional metastases with a high mortality rate are common, which is due to the extensive lymphatic system drainage of the tongue. Although the level of healthcare has significantly improved, the survival rate is still low with an...

Immunohistochemical Evaluation of Fascin in Oral Squamous Cell Carcinoma

Background and purpose: Squamous cell carcinoma (SCC) is the eighth most common cancer in men and the fifteenth in women. Localized recurrence and metastasis to regional lymph nodes are major problems in these patients. Fascin is a 55- kDa protein from the family of actin-binding proteins that is expressed in cells with membranous bronchial tubes. The aim of this study was to evaluate the expre...

Serum Endostatin Levels in Oral Squamous Cell Carcinoma

Introduction: Endostatin is a C-­terminal proteolytic fragment of collagen XVIII and, as with angiostatin and thrombospondin, is known as an anti­angiogenic agent. The aim of this study was to assess the level of serum endostatin in patients with oral squamous cell carcinoma (SCC), and its association with the clinicopathological characteristics of the tumor.   Materials and Methods:  Using an ...
