A case of recurrent invasive cribriform carcinoma of the breast mimicked the histological and mucin staining characteristics of adenoid cystic carcinoma. The diagnosis was based on negative immunocytochemical staining for laminin and ultrastructural evidence of luminal differentiation by cells lining the cystic spaces. Accurate characterisation of this type of breast tumour can be facilitated b...

The authors report a rare case of primary mucinous carcinoma of the skin initially diagnosed as a metastatic adenocarcinoma. The tumor occurred in the right axilla in a 75-year-old man. Initial pathological diagnosis was metastatic adenocarcinoma. However, no primary focus was found in the body. The revised diagnosis by the authors was primary cutaneous mucinous carcinoma. The tumor (1.5 cm) wa...

Primary cutaneous adenoid cystic carcinoma (PCACC) is a very rare malignancy. The differential diagnosis of PCACCs in pathology practice can be difficult and a group of primary and metastatic lesions, including adenoid basal cell carcinoma of the skin, should be considered in the differential diagnosis. Besides histomorphological clues, immunohistochemistry studies are very helpful in the diffe...

erbB2 gene plays an important role in carcinoma formation. erbB2 overexpression was observed in many types of tumours, including salivary carcinoma. However, a putative erbB2 and PTEN interaction remains largely unknown in salivary adenoid cystic carcinoma cells. The purpose of this study was to silence erbB2 gene and investigate the functional relationship between erbB2 and PTEN in SACC-83 sal...

UNLABELLED A 65 year-old male patient with a one year-duration tumoral growth located in the upper lip was diagnosed on incisional biopsy as epithelial-myoepithelial carcinoma. After wide surgical excision the histopathological analysis revealed the lesion was composed predominantly (>90%) of adenoid cystic carcinoma. In new sections it was found a very small and isolated area of adenoid cystic...

Our experience with 12 papillary breast lesions included eight intraductal papillomas, three primary papillary carcinomas, and one metastatic papillary ovarian carcinoma. Five of the eight intraductal papillomas displayed diagnostic findings including tridimensional papillary fragments of ductal cells with distended cytoplasmic vacoules and dense scalloped cytoplasm. Three intraductal papilloma...

We report a case of perineural spread of adenoid cystic carcinoma along the greater superficial petrosal nerve. The anatomy of this nerve also is reviewed.

PURPOSE To present experience with high dose-rate endobronchial brachytherapy in the treatment of primary tracheal tumors. PATIENTS AND METHODS Four patients with nonresected primary tracheal tumors are presented: 2 cases of squamous cell carcinoma of the trachea, 1 of recurrent adenoid cystic carcinoma, and 1 with recurrent plasmacytoma. All received brachytherapy, alone or as a boost for pr...

background and aims. salivary gland tumors are rare and specific lesions. there are differences in the incidence and frequency of salivary tumors in both minor and major salivary glands in different countries. this study was carried out to determine the prevalence of major and minor salivary gland tumors in ahvaz in the south of iran. materials and methods. all the cases, recorded in imam khome...

The Fifth edition of the World Health Organization classification digestive system and American Joint Committee on Cancer staging manual contain substantial refinements information for esophageal tumors. epithelial tumors esophagus are classified as benign, dysplasia, malignant groups. Dysplasia is divided into Barrett dysplasia squamous graded either low-grade or high-grade. Malignant often ad...
