Cancer of the esophagus is the eighth most common cancer by incidence worldwide and ranks sixth as the most common cause of cancer death. It is unique among the gastrointestinal tract malignancies because it embodies two distinct histopatologic types, squamous cell carcinoma and adenocarcinoma. Which type of cancer occurs in a given patient or predominates in a given geographic area depends on ...
Basaloid squamous cell carcinoma is an uncommon malignancy of the esophagus. We present two cases of basaloid squamous carcinoma of the esophagus. Both tumors histologically consisted of solid cell nests and displayed focal immunoreactivity for type IV collagen. The nests comprised pseudoglandular structures containing myxoid matrix. Transthoracic esophagectomy with lymph node dissection was pe...
squamous cell carcinoma (scc) of the buccal mucosa accounts for 23% to 37% of all intraoral cancers, the prognosis is generally poor. we reported a case of local invasion of buccal squamous cell carcinoma. a 32-year-old man referred to the clinic with a chief complaint of swelling in the right cheek region that initiated from 6 months ago and rapidly grow from one month ago. history of the pati...
Here, we present a case of a 78-year-old man that underwent gastrointestinal endoscopy because of one- monthhistory of dysphagia to liquids and solid foods with accompanying weight loss. On endoscopy, there was distalesophageal stenosis. Multiple biopsies were obtained. Histologic examination of the samples revealed normaltissue. The stenosis was treated by dilatation and abdomino pelvic comput...
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...
Primary tumors of the esophagus can be classified on the basis of cell origin into epithelial and nonepithelial tumors. Each category may be further subdivided into benign and malignant types. The nonepithelial tumors arise from the mesenchymal or supporting stromal tissue, most of them are benign. Nearly all esophageal cancers are carcinomas. Sarcomas rarely arise in the esophagus. The collisi...
BACKGROUND Recurrent laryngeal nerve (RLN) lymph node metastasis used to be shown a predictor for poor prognosis in esophageal squamous cell carcinoma. The purpose of this study was to evaluate the prognostic impact of RLN node metastasis and the number of metastatic lymph nodes in node-positive patients with squamous cell carcinoma of middle thoracic esophagus. METHODS A cohort of 235 patien...
OBJECTIVE After complete resection of carcinomas of the head and neck, including carcinoma of the cervical esophagus, the pattern of first failure is more often locoregional than distant metastasis. We retrospectively evaluated the safety and efficacy of the combination of post-operative radiation and concurrent chemotherapy with low-dose cisplatin for high-risk squamous cell carcinoma of the c...
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 cytology ...
