[Treatment of cutaneous nevocarcinomas].

For long, malignant melanoma of the skin was never treated other than surgically; in spite of considerable effort in this field, a large number of them remained with a very poor prognosis. In the severest cases, it was noted that the prognosis was little influenced by recent therapeutic progress. The latter, however, in the light of recent experience, seemed to justify the hope which was placed in it initially. The object of this report is to relate modern progress in the treatment based on clinical and pathological findings. It is the result of work undertaken during recent years by the research group on malignant melanomas of the Lariboisiére-Saint-Louis hospitals.

[Hyperlipoproteinemias in psoriasis].

The hyperlipoproteinaemia truly characteristic of psoriasis is the type IV or major endogenous hypertriglyceridaemia. It is found in 39 p. 100 of patients with psoriasis as compared to 18 p. 100 of our controls (though 6 p. 100 of the French population according to Turpin and De Gennes). It appears to be definitely genotypic, environmental factors playing only a minor role. This study would tend to integrate psoriasis into the category of the metabolic diseases, coinciding with the notion of troubles with glucose metabolism in psoriatics, since it is now accepted that 80 p. 100 of type IV hyperlipoproteinaemias are pre-diabetic.

Antibody patterns to herpesviruses in kaposi's sarcoma: serological association of european kaposi's sarcoma with cytomegalovirus.

Sera from patients with Kaposi's sarcoma (KS) were examined for antibody titres to cytomegalovirus (CMV), Epstein-Barr virus (EBV) and herpes simplex virus (HSV) types 1 and 2 by four techniques: indirect haemagglutination (IHA), complement fixation (CF), virus neutralization (NT) and indirect immunofluorescence (IF). The patients were classified, according to the stage of disease, as progressive and regressive. Control sera were obtained from healthy adults, matched for age, sex, race, socioeconomic status and geographic location, as well as from patients with melanoma, some of whom were receiving chemotherapy similar to that given to the KS patients. All KS sera contained CMV-neutralizing antibodies. Seventy-five percent of the European KS patients, mainly regressors, showed elevated anti-CMV titres by IHA with a significant increase in the geometric mean over the corresponding healthy adult group and the melanoma group. An overrepresentation of high anti-CMV titres, although less marked, was found by CF. There was no significant association with antibodies to EBV, HSV-1 and HSV-2 related antigens. By contrast, the African KS patients, mainly progressors, did not show a serologic association with CMV or with EBV and HSV-1 and 2. The implication of these results is discussed.

The lichen planus-like eruption after bone marrow transplantation.

A lichen planus-like eruption was seen in four patients after bone marrow transplantation. The skin and mucous membrane appearance closely mimicked lichen planus. The histopathology was also very similar to lichen planus. The occurrence of a lichen planus-like eruption (LPLE) after an immune basal cell damage related to the graft-versus-host reaction raised the question of the immune nature of this eruption. The correlation found between biological signs of graft-versus-host reaction and the out-break or relapse of the lichen planus-like eruption supports the hypothesis that the skin changes could be a sign of a chronic immune response against recipient epidermis.

Cytotoxicity of lymphocytes from healthy subjects and from melanoma patients against cultured melanoma cells.

The in vitro cytotoxicity of lymphocytes from forty-seven melanoma patients and thirteen healthy subjects for cultured melanoma cells was studied using a 51Cr release assay. Two different melanoma cell lines were used as target cells: one cultured in suspension (SK Mel1) and one tissue culture line growing as a monolayer (NK I1). The lymphocytes from most healthy subjects were found to be cytotoxic for these cultured cells, with individual variations. These repeatable cytotoxic reactions could not be explained on the grounds of previous isoimmunization. The lymphocytes from melanoma patients were also cytotoxic for the melanoma cell lines, but the highest degree of cytotoxicity was found in patients with primitive and localized tumours, and not in patients with metastases.

[Cutaneous manifestations of chronic atrophic polychondritis and their relation to aphtosis].

A young woman aged 23 showed the clinical feature of relapsing polychondritis. This disease included recurrent inflammation of right ear, nasal rib and larynx cartilages. She had also arthritis of ankle and wrist. She never had aphtosis before her cartilaginous disease. Buccal and genital erosions similar to aphtae occurred before each recurrent attack of cartilage inflammation. In one instance aseptic vesiculo-pustular and erythema nodosum like lesions occurred. This case raises the question of whether this is a never reported association of two diseases or relapsing polychondritis may have dermatological symptoms bordering aphtosis. The latter hypothesis is supported: firstly by the fact that skin symptoms of aphtosis had been reported separately in cases of relapsing polychondritis (buccal aphtae, pustular eruption, erythema nodosum, recurrent thrombophlebitis); secondly by a case very similar to our (Thivolet, see text) showing a typical feature of relapsing polychondritis with a complete dermatological aspect of aphtosis.
