G(IX) congeneic mouse strains, C57BL/6-G(IX) (+)(B6-G(IX) (+)) and 129-G(IX) (-), have been derived from the prototype strains, B6(G(IX) (-)) and 129(G(IX) (+)). The hybrids, (B6-G(IX) (+) x 129)F(1) (G(IX) (+)F(1)) and (B6 x 129-G(IX) (-))F(1) (G(IX) (-)F(1)), differ only in regard to genetic loci controlling G(IX) antigen expression. G(IX) (+)F(1) mice spontaneously produce G(IX) antibody and often show signs of autoimmune disease and lymphoproliferative disease. G(IX) (-)F(1) mice and mice of the two parental strains (B6-G(IX) (+) and 129) of G(IX) (+)F(1) do not produce G(IX) antibody and seldom show signs of these diseases. G((ERLD)), and G((RADA1)), antibodies, natural thymocytotoxic autoantibody, and antinuclear antibodies were produced by G(IX) (+)F(1) mice. However, these four antibodies were also found in the other strains. G(IX) (+)F(1) mice develop pronounced diffuse glomerulonephritis similar to that found in systemic lupus erythematosus in man. Incidence studies in which mice were examined according to age rather than state of health showed that the lesions occurred in 38% of G(IX) (+)F(1) mice but not in G(IX) (-)F(1), B6-G(IX) (+), or 129 mice. Lymphoproliferative lesions were either reticulum cell sarcoma (RCS) type A or reactive lymphoid hyperplasia (RLH). RCS occurred more often in G(IX) (+)F(1) (38%) than in G(IX) (-)F(1) (12%) or B6-G(IX) (+) (8%). No RCS occurred in mice of the 129 strain. RLH occurred in G(IX) (+)F(1) mice (10%) but not in the other strains. From these results, the following conclusions are drawn: (i) Severe glomerulonephritis and the increased occurrence of lymphoproliferative lesions in these animals depend on the presence of G(IX) antigen; (ii) besides genes controlling G(IX) antigen expression, other genes from both parental strains are required to create the basis in the progeny F(1) mice for the development of these diseases; and (iii) the chronic production of G(IX) antibody may be necessary for the development of the severe glomerulonephritis and for the increased occurrence of lymphoproliferative diseases in G(IX) (+)F(1) mice.

The development of a reticulum cell sarcoma in the lung of a patient with systemic lupus erythematosus treated with azathioprine for 18 months is described. This possible hazard of immunosuppressive therapy is discussed in relation to patients with SLE.

Enlargement of the cheeks may be due to a multitude of disorders, congenital, neoplastic, and in particular inflammatory. Congenital facial anomalies include cutaneous (and osseous) hemihypertrophy of the face and unilateral angiomatous malformations (e.g. Sturge-Weber-Krabbe Syndrome). Buccal enlargement due to dermal tumours include localized haemangiomas and lymphangiomas, lipomas and other benign connective tissue neoplasms, generalized disorders of the lymphatic or reticuloendothelial system including mycosis fungoides, reticulum cell sarcoma and other soft tissue malignancies, and cutaneous manifestations of malignant haemoblastoses, in particular chronic lymphatic leukaemia. Within the very large group of inflammatory skin swellings of the face a review is made of some bacterial pyodermias, severe forms of acne vulgaris, herpes zoster, lupus vulgaris, erysipelas, rosacea, steroid dermatitis, lupus erythematosus (discoid and systemic), toxic dermatitis, allergic eczema, urticaria, Quincke's oedema, and the Melkersson-Rosenthal syndrome. The importance of prevention and early detection of steroid-induced dermatitis is emphasized. This disorder, which is a pseudo-inflammatory disfiguring complication of prolonged topical steroid abuse, ranks in frequency with the skin problems most often seen in dermatological practice.

Red lunulae are associated with rheumatoid arthritis, systemic lupus erythematosus, alopecia areata, cardiac failure, hepatic cirrhosis, lymphogranuloma venereum, psoriasis, carbon monoxide poisoning, twenty-nail dystrophy, and reticulosarcoma. We examined four patients with red lunulae. Three had chronic obstructive pulmonary disease. Two of these three were alcohol abusers and were without any of the conditions previously associated with red lunulae. Two of the four also had palmar erythema. Histopathologic examination of the red lunula in one of the four cases did not show signs of neovascularization. We report our findings in these patients, which suggest that red lunulae result from increased arteriolar blood flow, a vasodilatory capacitance phenomenon, or changes in the optical properties of the overlying nail so that normal blood vessels become more apparent.

Three breeding lines, originating from dogs with SLE, have been established. Two lines were initiated by mating a female with SLE with a normal male. The third line resulted from a mating of two affected dogs. Brother-to-sister matings have reached the third generation in each line. In addition, backcross and outcross matings were carried out. More than one-third of the autopsied dogs had thymic abnormalities. The commonest lesion was a lymphoid follicle; the thymus of one dog contained multiple granulomas, and in one animal a reticulum cell sarcoma of the thymus was found. Multiple serological abnormalities, including positive LE cell tests, anti-nuclear antibodies (ANA), and rheumatoid factor, were found in the progeny. The development of ANA appeared unrelated to the incidence of positive LE cell tests. About 10% of the animals had rheumatoid factor in their serum. Control populations of dogs; including house pets; two other, unrelated lines of inbred dogs; and normal dogs housed in the same facility as the SLE colony did not have these abnormalities. The incidence of positive LE cell tests in the inbred, backcross, and outcross matings was not consistent with any conventional genetic mechanism of inheritance. It is conceivable that the results can be explained by vertical transmission of an infectious agent in a genetically susceptible individual.
