BEN'S NOMENCLATURE REVIEW - as promised:)

Based on parenchymal components: benign or malignant

• Suffix –oma attached to cell of origin (i.e. chondroma, fibroma, osteoma)

A benign epithelial tumor projecting from the surrounding surface. A

           -Papilloma: benign epithelial neoplasm producing microscopic or macroscopic finger-like projections from the surface. Projections are exophytic since they show outward growth from the surface.

            -Adenoma: benign epithelial neoplasm which forms glandular patterns or is derived from glands (i.e. colonic adenoma).

Hamartoma of the breast

            -Hamartoma: benign mass of disorganized mature, specialized cells or tissue indigenous to a particular site (i.e. hamartoma of the breast)

Misnomas (malignant but don’t sound like it)	Mixed Tissue
-        lymphoma -        multiple myeloma -        melanoma -        seminoma -        mesothelioma -        hepatoma (hepatocellular carcinoma) -        hypernephroma	-        Teratoma o   Tissue from germ lines in abnormal sites o   Mature and immature o   Benign, ovaries/testes are common targets -        Hamartoma o   Tissue that’s in normal site but not organized properly o   benign
