Retroperitoneal synovial sarcomas are very rare. The authors describe a 39-year-old male with a primary retroperitoneal synovial sarcoma showing a monophasic pattern. Immunohistochemically, the tumor cells were positive for cytokeratin AE1/AE3, epithelial membrane antigen, vimentin, S-100 protein, CD99 and calretinin. The differential diagnosis, clinical evolution and principles of treatment ar...

Generalized Modules for Membrane Antigens (GMMA) are outer membrane vesicles derived from Gram-negative bacteria that can be used to design affordable subunit vaccines. GMMA have been observed induce a potent humoral immune response in preclinical and clinical studies. In addition, studies, it has found exploited as optimal antigen carriers both protein saccharide antigens, they able promote th...

We compared 4 breast cylindromas with 50 dermal cylindromas and 8 adenoid cystic breast carcinomas. Except for a modest increase in the number of eccrine ducts and reactive Langerhans cells in dermal cylindromas, breast and dermal cylindromas showed identical histologic and immunohistochemical features. Both were characterized by epithelial islands containing central basaloid cells and peripher...

We report a case of 32-year-old male who was evaluated for right chest pain and cough with streaky hemoptysis. Chest X-ray contrast-enhanced computerized tomography scan the showed large (20x16×16 cm), heterogeneously enhancing mass arising from lower lobe. Ultrasound-guided Tru-cut biopsy revealed spindle cell sarcoma. In immunohistochemistry, tumor cells expressed epithelial membrane antigen,...

Immunohistochemical characterization of 14 cases of intracranial cysts was performed. Among these 14 cases, five different types of cysts were represented; Rathke's cleft cyst (4 cases), neurenteric cyst (2 cases), colloid cyst (1 case), choroidal epithelial cyst (2 cases) and arachnoid cyst (5 cases). Immunohistochemical evaluation utilized antibodies to glial fibrillary acidic protein (GFAP),...

Background: This study was undertaken to establish the characterization of cultured oral mucosal epithelium and introducing them as an alternative source for reconstruction of ocular surface disease. Methods: Human oral epithelial cells were cultured on simple media (DMEM/HF12) as control and co-cultured on mitomycin C-treated 3T3 feeder layer, on the amniotic membrane (AM) without nitrocellulo...

Bispecific antibodies (BsAbs) have been developed, with one antigen-binding site coordinated against the CD3 receptor (which activates cytotoxic T lymphocytes) and other specific antigens found on cancer cells (CD19, CD20, CD33, CD123, HER2, epithelial cell adhesion molecule [EpCAM], BCMA, CEA, others) [1].

The common acute lymphoblastic leukemia antigen (CALLA), as defined by J-5 murine monoclonal antibodies, was detected on renal tubular and glomerular cells from fetal and adult donors by an indirect immunoperoxidase technique. CALLA could also be detected on epithelial cells of the fetal small intestine and on myoepithelial cells of adult breast but not on myoepithelial cells of the salivary gl...
