Adenomyoepithelioma is a proliferation of both epithelial and myoepithelial elements. It is a rare neoplasm first described by Hamperl in 1970 [1]. The term has been used to describe many lesions that are part of a spectrum of changes with myoepithelial prominence occurring in the breast and in other sites. Other lesions in this class include adenoid cystic carcinoma, pleomorphic adenoma, myoep...
Myoepithelioma of the skin and soft tissue is a newly recognized entity with characteristic histopathologic and immunohistochemical features, which should be differentiated from a variety of tumors. Myoepitheliomas are in the same pathologic spectrum of mixed tumors and parachordomas. Tumors comprised mostly of myoepithelial cells without obvious epithelial differentiation are designated myoepi...
Myoepitheliomas are benign salivary gland tumors and account for less than 1% of all salivary gland tumors. They are usually located in the parotid gland. The soft palate is very rare affected site. The differential diagnosis of myoepitheliomas should include reactive and neoplastic lesions. The treatment of myoepitheliomas is complete removal of the tumor. Herein, we report a case with giant m...
background & objectives: chronicity of lupus nephritis (ln) should be considered for interaction of cell mediated immunity (cmi) and dendritic cells in glomeruli and tubulointerstitial areas. in this study establishment of immunohistopathological changes of dendritic cells and other immune effector cells in lupus nephritis comparing with non-lupus nephritis was performed. materials & m...
AIM HER2 overexpression has been reported in a minority of urothelial carcinomas, but little is known about HER2 protein expression and gene alterations in plasmacytoid urothelial carcinoma, a rare and aggressive variant. The aim of this study was to clarify the HER2 status in plasmacytoid urothelial carcinomas. METHODS Six cases of plasmacytoid urothelial carcinoma were included, in which we...
Chemerin is a chemotactic agent that was recently identified as the ligand of ChemR23, a serpentine receptor expressed by activated macrophages and monocyte-derived dendritic cells (DCs). This paper shows that blood plasmacytoid and myeloid DCs express functional ChemR23. Recombinant chemerin induced the transmigration of plasmacytoid and myeloid DCs across an endothelial cell monolayer. In sec...
