Thyroid squamous cell carcinoma is very rare. At present, it limited to case reports. Since the thyroid follicular epithelium non-squamous epithelium, how primary (SCC) of occurs still a controversial issue. Hashimoto’s thyroiditis (HT) considered be an independent risk factor for cancer, under basis HT, tumor cells evolve and develop papillary (PTC), particularly de-differentiate into SCC elus...
Bladder reconstruction using bowel segments, especially the ileum, has become a realistic option for urinary diversion. There is only one prior case of squamous cell carcinoma of the ileal neobladder that has been reported in the clinical literature. Here we report a patient with a spectrum of squamous cell lesions, including squamous cell carcinoma, sarcomatoid carcinoma, squamous papilloma an...
BACKGROUND Primary squamous cell carcinomas of the colorectum are very uncommon. Until now, to the best of our knowledge, only 114 cases of squamous cell carcinoma in the colorectum exist in the reported literature. Here we report a case of squamous cell carcinoma of the rectum in the ethnic Kashmiri population in northern India. CASE PRESENTATION The case of a 60-year-old male patient (Asian...
OBJECTIVE To demonstrate the role of angiogenesis in the progression of cutaneous squamous cell carcinoma. INTRODUCTION Angiogenesis is a pivotal phenomenon in carcinogenesis. Its time course in cutaneous squamous cell carcinoma has not yet been fully established. METHODS We studied the vascular bed in 29 solar keratoses, 30 superficially invasive squamous cell carcinomas and 30 invasive sq...
UNLABELLED We report the case of a 39-year-old female with primary vaginal squamous cell carcinoma arising from a squamous inclusion cyst of the posterior wall. The tumor was located in the vaginal wall and extended into the rectovaginal septum. The overlying mucosa was intact. Histologically, there was invagination of the surface squamous vaginal epithelium forming a cystic lesion. In some are...
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 ra...
INTRODUCTION Squamous cell carcinoma is the most common malignant tumor of the oral cavity and one of the 10th most common causes of death. It arises from dysplastic oral squamous epithelium. By considering the pathogenesis of squamous cell carcinoma, the smooth and intact surface for this lesion is not usual. CASE PRESENTATION A painful nodular lesion with smooth surface on the left buccal m...
background & objective: chronic non healing ulcers or scar undergoing malignant transformation is a rare phenomenon with an estimated incidence of 2%. though, numerous predisposing factors have been identified, still it is rarely diagnosed and commonly mistaken for a benign condition. the objective of this study was to verify the efficacy of the fine needle aspiration cytology/ scrape cytol...
Background: Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Objectives: Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (Ha...
background: cutaneous malignancies are common in dermatologic practice. due to their relation to sun exposure the characteristics of these malignancies can differ in various geographic locations. this study intends to determine the characteristics of surgically treated cutaneous malignancies and various surgical modalities that have been applied. methods: this was a retrospective study of patie...
