We describe a rare and interesting case of a basaloid squamous cell carcinoma (BSC) of the uterine cervix with metastasis in the left iliac region diagnosed by fine needle aspiration (FNA). A 54-year-old woman underwent FNA because of a mass in the left iliac region. The material was processed by conventional liquid based cytology (ThinPrep), and by the cell-block technique and diagnosis was ba...

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...

The pathology and results of treatment of 36 cases of basaloid carcinomas of the anal canal are described. This variant of squamous cell carcinoma of the anal region arises from the entodermal-ectodermal junctional zone of the anal canal at or above the dentate line. Basaloid carcinomas have histological characteristics which resemble basal cell carcinoma of the skin, in particular the presence...

PURPOSE The basaloid carcinoma (pure) and the (mixed) basaloid variant of lung squamous cell carcinoma (SCC) have a dismal prognosis but their underlying specific molecular characteristics remain obscure and no therapy has proven to be efficient. EXPERIMENTAL DESIGN To assess their molecular specificity among other lung SCCs we analyzed DNA copy number aberrations and mRNA expression pangenom...

Endobronchial metastases from extrapulmonary neoplasms are rare events and there is no report on the metastasis originating from esophageal cancer. Basaloid squamous carcinoma of the esophagus is a rare histologic type, which is known as biologically aggressive phenotype. We describe a rare case of metachronous endotracheal metastasis originating from esophageal basaloid squamous carcinoma. A 7...

Basaloid squamous cell carcinoma (BSCC) of the colon is rarely found proximal to the anal canal. We report a case of an 81-year-old woman who was diagnosed with squamous cell carcinoma (SCC) of the lung without metastasis and BSCC of the sigmoid with differing histologic findings suggesting that these tumors were separate primary neoplasms. SCC of the colon has a dismal prognosis. Surgery is th...

intraosseous squamous cell carcinoma is a rare type of squamous cell carcinoma that requires accurate and early diagnose which is important due to its invasive feature. this article presents a rare case report on intraosseous carcinoma in a 33-year-old patient. the case was a 33-year-old man who was referred to oral disease department of babol college of dentistry complaining of chin pain. in t...

UNLABELLED Basaloid squamous cell carcinoma is a variant of squamous cell carcinoma, preferentially arising in the head and neck region. Current reports point to an association of basaloid squamous cell carcinoma (BSCC) and human papilloma virus (HPV) infection. This virus is supposed to be an aetiological factor in this entity. The aim of this study was to analyse the HPV infection status in d...
