Squamous cell carcinoma is one of the most frequent cutaneous carcinomas, this neoplasic process inducing cellular and tumoral immune response modifications. Our study refers at 60 patients, squamous cell carcinoma diagnosed, at whom we determined IL-2, IL-6 and TNF-alpha, using ELISA technique. The discovered results were different, depending on the differentiation form. The cellular immune re...

Sir, Squamous cell carcinoma (SCC) can occur anywhere on the skin and in mucous membranes with a squamous epithelium (1). Malignant tumours producing granulocyte colony-stimulating factor (G-CSF) have been reported in lung cancer, thyroid carcinoma, bladder carcinoma and cutaneous angiosarcoma (2). We encountered a case of G-CSF-producing SCC, which was diagnosed by immunohistochemical staining...

BACKGROUND Several risk factors are generally accepted to portend more aggressive behavior of cutaneous squamous cell carcinoma. These include tumor size, tumor depth, histologic subtype, location on the lip or ear, tumor arising in scar, recurrent tumor, and tumor demonstrating perineural invasion. Organ transplant recipients can have significant morbidity and mortality from squamous cell carc...

An epidermal cyst is a common benign subcutaneous tumor and rarely develops malignancy. We report a case of an undifferentiated cutaneous squamous cell carcinoma (SCC) that arose from an epidermal cyst on the left side of the neck. The epidermal cyst had rapidly increased in size and presented cauliflower-like tumor. Histological study revealed undifferentiated squamous cell carcinoma that was ...

Basosquamous carcinoma of the skin is a relatively rare cutaneous neoplasm that has significant metastatic potential and a metastatic rate greater than that of basal cell and squamous cell carcinoma. We describe the use of lymphatic mapping and sentinel lymph node biopsy in a 63-year-old man after identification of basosquamous carcinoma. Sentinel lymph node biopsy, which is a standard tool to ...

introduction: esophageal squamous-cell carcinoma (scc) is one of the most common malignancies in iran. to reduce the incidence of esophageal scc, it is important to recognize the controllable risk factors and prevent them. celiac disease is widely known as a possible risk factor for esophageal scc.  thus, we decided to assess the frequency of celiac disease in esophageal scc patients in north e...

it has been argued that oral lichen planus (olp) may increase the risk of oral cancer. patients with olp may be at an increased risk for developing of oscc (oral squamous cell carcinoma). here, the author reports a case of olp initially presenting with a clearly benign olp lesion that transformed into oscc over a course of 18 months. this report may provide a clear evidence for olp lesion as a ...

esophageal squamous cell carcinoma is a rather common cancer in northern iran. incidence of adenocarcinoma of esophagus has an increasing trend in iran. co-existence of both cancers in one patient is very rare. we report a middle age woman from northern iran with a typical presentation of esophageal cancer, who was found to have a dual esophageal cancer. the disease was found in the advanced st...

esophageal cancer (ec) is the eighth most common cancer and sixth most frequent cause of cancer mortality worldwide. esophageal squamous cell carcinoma (escc) is the most common type of ec. escc develops by progression from premalignant lesions, which are called esophageal squamous dysplasia (esd). prevention is the most effective strategy for controlling this disease. generally, two methods ma...
