Teratomas are nonseminomatous germ cell tumors composed of elements derived from more than one germinal layers (endoderm, mesoderm, and ectoderm). Malignant transformation of teratoma in the testis is well known; however, benign somatic neoplasm arising in a testicular teratoma is a rare occurrence. We report a case of meningothelial variant of meningioma arising in a pure and mature teratoma of the testis in a 5-year-old boy. Immunohistochemistry was positive for epithelial membrane antigen and vimentin. To our knowledge, this is the first report of meningothelial meningioma in a prepubertal testicular teratoma.

The article presents a case study of a 48-year-old lady presented with a palpable lump in left breast for the last two years. On examination, there was a large nontender, hard lump occupying entire breast with edema of the overlying skin and ulceration of the nipple-areola complex. Bilateral mammography showed a large, lobulated mass with indistinct margins involving the entire left breast. Ultrasonographic examination revealed solid cystic mass with increased vascularity in the solid areas.
