 Unspecified reproductive status not specified observed 35 days Teratocarcinoma (malignant teratoma), extra-gonadal J:94314
Image Caption:The neoplasm shows epithelial (left portion of the photomicrograph) and neural (right portion of the photomicrograph). An epithelial structure at the center of the photomicrograph is distended by a mucoid substance surrounded by a one cell-thick ciliated cuboidal epithelium reminiscent of the epithelium of the respiratory tract. Vacuolated cells may represent areas of chondromatous or lipomatous differentiation. Scattered areas of skeletal muscle are also present.

Method / Stain:H&E
Image Caption:This photomicrograph illustrates areas of osteo-chondromatous (OC), neural (N), epithelial (E), and skeletal muscle (M) differentiation. Areas of osteo-chondromatous differentiation are characterized by the formation of cartilaginous masses with endochondral ossification. Areas of skeletal muscle differentiation are composed of bundles of immature myocytes separated by small amounts of fibrovascular stroma. Areas of epithelial differentiation are composed of trabeculae, nests and acini. Some of the acini are surrounded by goblet cells and are moderately distended by a mucoid substance. Areas of neural differentiation are composed of glial cells and neurones scattered in a pale acidophilic substance consistent with glia.

Method / Stain:H&E
Image Caption:The neoplasm contains areas of osteo-chondromatous (OC), neural (N), skeletal muscle (M) and epithelial (E) differentiation.

Pathologist:Mikaelian I
Method / Stain:H&E
Image Caption:The tumor, in this portion, shows epithelial and neuro-endocrine differentiation. One area of epithelial differentiation is characterized by the formation of a dilated tubule lined by a one cell-thick columnar epithelium reminiscent of the respiratory epithelium. However, most epithelial areas are composed of thick trabeculae and tubules lined by a pluristratified epithelium. These cells are polygonal to columnar and have a moderate amount of basophilic to acidophilic cytoplasm. Neuroendocrine-like areas are characterized by the formation of small nests composed of columnar to fusiform cells with a pale acidophilic cytoplasm. Mitotic index is high and numerous neoplastic cells undergo single cell necrosis.
