background: lung cancer ranks among the most common and most lethal malignancies worldwide. once vascular or lymphatic invasions occur, metastatic dissemination to distant sites is common. bone, liver, adrenals, and brain are the most frequent sites of the distant disease. in this study we present a case of squamous cell carcinoma of lung with metastasis of the left knee bursa.case presentation...

the association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. from 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the otolaryngology department of khalili hospital, affiliated with shiraz university of medical sciences, shiraz, iran. in three patients, synchronous occurrence of ...

The most usual form of the endocrine carcinoma is thyroid cancer (TC). In addition to papillary thyroid carcinoma (PTC), recent studies revealed incidence of RET/PTC rearrangement in other tumors, like Hürthle cell carcinoma (HCC) and even in non-carcinomatous disorders like Hashimoto's thyroiditis. Here, we present a case with concurrence of papillary thyroid carcinoma and Hürthle cell carcino...

Squamous cell carcinoma (SCC) of the skin is one of the mostcommon non melanoma skin cancers (NMSC), along withbasal cell carcinoma (BCC). Besides ultraviolet radiation,exposure to industrial agents, ionizing radiation, and areas ofchronic inflammation are associated with the development ofSCC. Squamous cell carcinoma may also be associated withforeign bodies. We report a rare case of cutaneous...

background and aims. mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. the distribution and significance of mast cells in many tumors have been demonstrated. however, few studies have evaluated mast cell infiltration in salivary gland tumors. in this study, mast cell counts were evaluated in benign and malignant salivary gland tumors. mat...

objectives : squamous cell carcinoma (scc) is the most common malignant neoplasm of the oral cavity and a public health threat. tumor progression is believed to be influenced by angiogenesis as well as tumor cell proliferation; however, the correlation of these two factors in tongue scc still remains unclear. this study aimed to assess the correlation of these two factors in tongue scc. materia...

this study was conducted to optimize a highly efficient mrna transfection into dendritic cells (dc) derived from esophageal squamous cell carcinoma (escc) patients. applying an electroporation technique, in vitro synthesized green fluorescent protein (gfp) mrna was transfected as an indicator into the dcs derived from a healthy donor. flow cytometry revealed 84.9% transfection efficiency for dc...

background and objective: clinical behavior of basal cell carcinoma (bcc) is known to be different according to histological growth pattern and basosquamous cell carcinomas (bsc) are known with their aggressive behavior and metastatic capacity. in this study, we evaluated bcl-2 and cyclin d1 expressions in bcc and bsc cases comparatively, to explore their predictive value on the aggressive beha...

conclusions nbi cystoscopy improved the detection rate. although false positives were more common with nbi, this was not statistically significant. nbi found additional aggressive tumors, which underscores the impact of detection in eortc recurrence risk scoring. results fifty patients, aged 63.86 ± 10.05 years, were enrolled. the overall detection rate was 98.9% for nbi vs. 89.4% for wli (p = ...
