    Abstract:
    Large cell calcifying Sertoli cell tumor of the testis (LCCSCT) is a rare tumor that is usually benign and multifocal. It may be associated with hereditary endocrine anomalies such as Carney's and Peutz-Jeghers syndromes. Malignant forms are exceptional. Two cases of LCCSCT, one malignant and one benign are described. Both were composed of cords and trabeculae of large polygonal cells embedded in a myxoid and fibrous stroma with areas of calcification. The malignant tumor showed nuclear atypia, necrosis, and abundant mitoses. The cells were positive for vimentin and S-100 protein, and the intercellular space for laminin and collagen type IV. By electron microscopy, nucleolonemas and multilayered basal lamina were seen. The benign tumor was positive for vimentin and S-100 protein, and ultrastructurally showed less basal lamina.
