Myoepithelial-epithelial carcinoma (MEC) is a low malignancy grade neoplasia which has a prevalence of 1% to 2% among all primary tumors of the salivary gland. It has a higher incidence at 60 years of age. About 60% of the patients are females. The parotid gland is the most often reported anatomical site; nonetheless, other sites have been reported, such as the submandibular gland, minor saliva...
Machine learning systems have recently received increased attention for their broad applications in several fields. In this study, we show for the first time that histological types of breast tumors can be classified using subtle morphological differences of microenvironmental myoepithelial cell nuclei without any direct information about neoplastic tumor cells. We quantitatively measured 11661...
An 8-year-old male neutered standard dachshund was presented with a slowly growing mass in the left submandibular salivary gland. Histopathological examination revealed a tumour that was composed of bilayered duct-like structures with an inner layer of ductal cells and an outer layer of clear cells. Both inner and outer cells in the greater part of the tumour exhibited low to moderate atypia an...
The apocrine type of encapsulated papillary carcinoma (ECP-A), of the breast is a rare neoplasm and there are only eight cases reported to date. Herein, we report the ninth case. A 68-year-old Japanese woman presented with a left breast mass. The cytoplasm of the tumour cells showed positive immunostaining for GCDFP-15. Myoepithelial cells were absent within the papillary structures and at the ...
BACKGROUND Carcinosarcoma of the salivary glands is a rare neoplasm, and the minimally invasive form constitutes a subgroup with a more favorable prognosis. The cytomorphologic features of this neoplasm can be appreciated on fine-needle aspiration biopsy. METHODS AND RESULTS We present a patient with a minimally invasive carcinosarcoma ex non-recurrent pleomorphic adenoma (Ca ex PA) who under...
