| aggregated lymphatic nodules | Lymphoid organs located in the sub mucosal tissue of the mammalian gut containing very high proportions of IgA secreting precursor cells. The patches have B and T dependent regions and germinal centres. A specialised epithelium lies between the patch and the intestine. Involved in gut associated immunity. (18 Nov 1997) |
| Albini's nodules | Minute fibrous nodule's on the margins of the mitral and tricuspid valves of the heart, sometimes present in the neonate and representing foetal tissue rests; described previously by Cruveilhier. Compare: nodule of semilunar valve. (05 Mar 2000) |
| apple jelly nodules | Descriptive term for the papular lesions of lupus vulgaris, as they appear on diascopy. (05 Mar 2000) |
| Aschoff nodules | <pathology> Small granulomas composed of macrophages, lymphocytes and multinucleate cells grouped around eosinophilic hyaline material derived from collagen. Characteristic of the myocarditis of rheumatic fever. (18 Nov 1997) |
| Bohn's nodules | Tiny multiple cysts in newborns. They are found at the junction of the hard and soft palates and along buccal and lingual parts of the dental ridges and are derived from epithelial remnants of mucous gland tissue. (05 Mar 2000) |

| Gamna-Gandy nodules | Small firm spheroidal or irregular foci that are yellow-brown, brown, or rustlike in colour, occurring chiefly in the spleen in such conditions as congestive splenomegaly and sickle cell disease, and consisting of relatively dense fibrous tissue or collagenous fibres impregnated with iron pigment and calcium salts; probably result from organization and scarring of sites where small perivascular haemorrhages occurred. Synonym: Gamna-Gandy nodules, Gandy-Gamna bodies, siderotic nodules. (05 Mar 2000) |
| malpighian nodules | Small nodular masses of lymphoid tissue attached to the sides of the smaller arterial branches. Synonym: folliculi lymphatici lienales, malpighian bodies, malpighian corpuscles, malpighian glands, malpighian nodules, splenic corpuscles, splenic lymph nodules. (05 Mar 2000) |

| milkers' nodules | An infection of cows' udders by pseudocowpox virus, a member of the Poxviridae, that is transmitted to the fingers and hands of milkers, producing nodules and lymphangitis, and occasionally widespread papular or papulovesicular eruptions; human infection is transferable to uninfected cows. Synonym: milkers' nodes, paravaccinia, pseudocowpox. (05 Mar 2000) |
| picker's nodules | Lichenified skin nodules seen in prurigo nodularis. (05 Mar 2000) |
