In a biopsy, a physician removes all or a section of a tumor through surgical means or by using a large bore needle to obtain a sample. The pathologist then analyzes the sample under a microscope and makes the diagnosis for a particular type of cancer such as ACC based upon the shape, structure, framework (stroma), color and growth pattern of the cells. ACC tumors are characterized by a distinctive pattern in which abnormal “nests” or cords of certain cells (epithelial cells) surround and/or infiltrate ducts or glandular structures within the affected organ. These structures are typically filled with a mucus-like material or contain abnormal fibrous membranes (hyaline membranes).
