title: [Testicular teratoma with meningothelial elements].
abstract: A case of a mature adult teratoma of the right testicle in 34-year-old man is reported. Microscopically, well-differentiated gut and respiratory epithelium prevailed in the lesion. There were also epidermis and well-developed skin adnexa. In addition, a focus of a meningothelial cell proliferation containing psammoma bodies was detected. There were also a peripheral nerve and glial tissue adjacent to the meningothelial elements. The meningothelial cells were immunohistochemically positive for EMA and claudin and negative for S-100-protein, cytokeratins (AE1-AE3, CAM5.2), desmin, and chromogranin A. The glial tissue was positive for
