gum·mas

(gŭm'ă, ă-tă, -ĕz),
An infectious granuloma that is characteristic of tertiary syphilis, but does not always develop, and that may be solitary (as large as 8-10 cm in diameter) or multiple and diffusely scattered (1 mm or less in diameter). Gummata are characterized by an irregular central portion that is firm, sometimes partially hyalinized, and consisting of coagulative necrosis in which "ghosts" of structures may be recognized; a poorly defined middle zone of epithelioid cells, with occasional multinucleated giant cells; and a peripheral zone of fibroblasts and numerous capillaries, with infiltrated lymphocytes and plasma cells. As gummas become older, an irregular scar or rounded fibrous nodule persists.
Synonym(s): syphiloma

gumma

[gum′ə] pl. gummas, gummata
Etymology: AS, goma, gum
1 a granuloma, characteristic of tertiary syphilis, varying from 1 mm to 1 cm in diameter. It is usually encapsulated and contains a central necrotic mass surrounded by inflammatory and fibrotic zones of tissue. Infectious organisms of the genus Treponema may be found in a gumma. The lesion may be localized or diffuse, occurring on the trunk, legs, and face and on various internal organs, especially the liver. It can also form in the brain, leading to neurological problems. Rupture of a gumma produces a shallow ulcer that heals slowly.
2 a soft granulomatous lesion that sometimes accompanies tuberculosis.

gumma

One of the principle features of late (tertiary) SYPHILIS. The gumma is a localized mass of GRANULATION TISSUE, with a necrotic centre of a gum-like consistency. It occurs as a result of toxic destruction of tissue and can occur anywhere in the body, including the intestines, the liver and the brain.
