Q

atypia

A

Atypia is deviation from the normal. The condition of being uncharacteristic or lacking uniformity nuclear atypism of cells characterizes certain precancerous conditions.

The condition of being irregular or not conforming to type. Morphological atypia is very important in tumor investigation.

divided into tissue and cellular atypia

Q

gompertzi curve

A

Discovered by Benjamin Gompertz, a nineteenth-century actuary, the Gompertzian growth curve describes the complex pattern of tumor growth.

The curve has an early, almost exponential growth rate followed by slower growth rate which reaches a plateau as tumors grow larger in size.

Q

Benign tumor nomenclature

A

Attaching the suffix-oma to the cell origin of
the name of organ and derived tissue cell + oma
e.g. adenoma of thyroid. adeno- refers to glandular tissue

More detail:
The name of organ and derived tissue/cell +
morphologic character + oma
e.g. skin papilloma, ovarian cyst adenoma

Q

malignant tumor nomenclature

A

Carcinoma: Malignant tumors of epithelial
cell origin.

The name of organ and derived tissue/ cell +
carcinoma.
e.g. adenocarcinoma of thyroid.

More details:
The name of organ and derived tissue/ cell +
morphologic features + carcinoma

e.g. papillary carcinoma of skin, ovarian

Q

Blastoma

A

is “special” nomenclature

caused by malignancies in precursor cells, often called blasts. The suffix -blastoma is used to imply a tumor of primitive, incompletely differentiated (or precursor) cells, or
nervous tissue, most of them are malignant.

e.g. Medulloblastoma, retinoblastoma,
nephroblastoma
