BACKGROUND: Biphasic lung cancers with admixtures of adenocarcinoma and sarcomatoid components but lacking true mesenchymal differentiation (sarcomatoid adenocarcinomas) are rare, and extensive studies of their clinicopathological characteristics and histogenesis have not been performed. MATERIALS AND METHODS: Six surgically resected sarcomatoid adenocarcinomas were compared clinicopathologically with 317 standard adenocarcinomas, and studied ...

OBJECTIVE: The monoclonal antibody (mAb) designated as mAb Das-1 was generated against a colonic epithelial protein. It reacts with bronchiolar epithelium and submucosal glands and weakly with alveolar lining cells of fetal lung. Adult alveolar epithelium is, however, nonreactive for mAb Das-1. The present study was designed to evaluate the ...

Histological diagnosis of malignant mesothelioma (MM) and differentiation from adenocarcinoma is often difficult. A number of clinical, radiologic, histologic and histochemical criteria have been used as diagnostic aids, but most cases cannot be readily classified on the basis of these characteristics. In recent years, a panel of immunohistochemical anti-bodies have ...

We describe a very rare association between intraepithelial, extramammary Paget's disease and human papillomavirus- (HPV) negative, keratinized type of VIN III observed in two elderly women. In both cases, morphological and immunohistochemical investigation showed two heterogeneous but intimately admixed neoplastic populations of vulvar epithelium. Atypical keratinocytes stained markedly and diffusely ...

Epithelioid angiomyolipoma is a recently recognized clinicopathologic entity first described by Martignoni et al. in 1995. Since then, several articles have further clarified its histogenesis and histologic features. Due to the presence of polygonal cells with voluminous cytoplasms, this neoplasm is often mistaken for renal-cell carcinoma. In this case presentation, ...

Previously we have reported that Drc1p/Cps1p, a 1,3-beta-glucan synthase subunit, is essential for division septum assembly in Schizosaccharomyces pombe. In this report, we present evidence that S. pombe Bgs2p, a 1,3-beta-glucan synthase that shows 56% identity to Drc1p/Cps1p, is essential for maturation of ascospore wall in S. pombe, but is ...

Heterotopic adrenal tissue is not uncommon, especially in the urogenital system. Adrenocortical tissue in the placenta, however, is presumably very rare. To our knowledge, four cases have been published. There are several different theories to explain such a heterotopia. According to our findings, an embolic spread of adrenal precursor cells ...

The present report describes the case of a 21-mo-old boy with a fetal rhabdomyomatous nephroblastoma (FRN) diagnosed by fine-needle aspiration cytology (FNAC). The smears contained numerous isolated or clustered, deeply eosinophilic, thin, elongated rhabdomyoblasts with oval nuclei. Some of these cells presented cross-striations. Peculiar clusters of small, deeply eosinophilic, round ...
