An Adenocarcinoma characterized by the presence of Cells resembling the glandular Cells of the Endometrium. It is a common histological type of ovarian Carcinoma and ENDOMETRIAL Carcinoma. There is a [..]

An Adenocarcinoma of the Thyroid Gland, in which the Cells are arranged in the form of follicles. (From Dorland, 27th ed)

Cancer of the Human Mammary Gland.

An invasive (infiltrating) Carcinoma of the mammary ductal system (Mammary Glands) in the Human Breast.

Metastatic Breast cancer characterized by Edema and Erythema of the affected Breast due to Lymphatic Metastasis and eventual obstruction of Lymphatic Vessels by the cancer Cells.

A primary malignant Neoplasm of the Pancreatic Islet Cells. Usually it involves the non-Insulin-producing Cell types, the Pancreatic alpha Cells and the pancreatic delta Cells (Somatostatin-Secreting [..]

A Tumor of undifferentiated (anaplastic) Cells of large size. It is usually bronchogenic. (From Dorland, 27th ed)

A primary malignant Neoplasm of epithelial liver Cells. It ranges from a well-differentiated Tumor with Epithelial Cells indistinguishable from normal Hepatocytes to a poorly differentiated Neoplasm. [..]

A infiltrating (invasive) Breast cancer, relatively uncommon, Accounting for only 5%-10% of Breast Tumors in most series. It is often an area of ill-defined thickening in the Breast, in contrast to th [..]

A Carcinoma composed mainly of epithelial Elements with little or no stroma. Medullary Carcinomas of the Breast constitute 5%-7% of all mammary Carcinomas; medullary Carcinomas of the Thyroid comprise [..]

An Adenocarcinoma producing Mucin in significant amounts. (From Dorland, 27th ed)

A Tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any Age Group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the Salivar [..]

A group of Carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue Cells", granular Chromatin, and an attenuated rim of poor [..]

A noninvasive (noninfiltrating) Carcinoma of the Breast characterized by a proliferation of malignant Epithelial Cells confined to the mammary ducts or lobules, without Light-Microscopy evidence of in [..]

A heterogeneous aggregate of at least three distinct histological types of Lung cancer, including Squamous Cell Carcinoma; Adenocarcinoma; and Large Cell Carcinoma. They are dealt with collectively be [..]

A contagious, neoplastic, Pulmonary Disease of Sheep characterized by Hyperplasia and Hypertrophy of Pneumocytes and Epithelial Cells of the Lung. It is caused by Jaagsiekte sheep retrovirus.

Carcinoma that arises from the Pancreatic Ducts. It accounts for the majority of cancers derived from the Pancreas.

A malignant Neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic Epithelial Cells. (Stedman, 25t [..]

A heterogeneous group of sporadic or hereditary Carcinoma derived from Cells of the Kidneys. There are several subtypes including the clear Cells, the papillary, the chromophobe, the collecting duct, [..]

An Adenocarcinoma with a hard (Greek skirrhos, hard) structure owing to the formation of dense Connective Tissue in the stroma. (From Dorland, 27th ed)

A malignant Tumor of the Skin appendages, which include the Hair, Nails, Sebaceous Glands, Sweat Glands, and the Mammary Glands. (From Dorland, 27th ed)

An anaplastic, highly malignant, and usually Bronchogenic Carcinoma composed of small ovoid Cells with scanty Neoplasm. It is characterized by a dominant, deeply basophilic nucleus, and absent or indi [..]
