[Paraneoplastic acrokeratosis]. / Acrokératose paranéoplasique (A. P. N.).

The authors discuss the main features of paraneoplastic acro keratosis, a new cutaneous marker of malignancy. Clinically, the condition begins at the extremities of the limbs and spreads upwards secondarily. The eruption is psoriasis-like squamous erythema of the face, hands and feet. Nail changes are present from the onset. These lesions are always associated with a malignant epithelioma, usually of the spino-cellular type localised in the upper respiratory and digestive tracts. Surgical cure of the primary malignant tumour leads to regression of the skin lesions which reappear in case of relapse.

Acrokeratosis paraneoplastica--a new cutaneous marker of malignancy.

The historical background and the main clinical features of a specific paraneoplastic dermatosis, acrokeratosis paraneoplastica, are reviewed. Typical features are erythematous scaly lesions on the extremities, ears and bridge of the nose, associated with a malignancy, most frequently in the laryngopharyngeal region.

[The association tretinoin-erythromycin base: a new topical treatment for acne. Results of a multicentric trial on 347 cases (authors transl)]. / L'association tretinoïne-erythromycine base: nouveau traitement local de l'acné. Etude multicentrique sur 347 cas.

A multicentric trial involving ten dermatological departments was conducted to evaluate the efficacy and tollerance of ANTIBIO-ABEREL (an association of Tretinoin and Erythromycin base) in 347 patients with persistant acne. Complete healing or considerable improvement was obtained in 85% of cases. This new treatment was active against both inflammatory lesions (papules and pustules) and retentional elements (microcysts and open comedones). It was also rapidly active, as very favorable results were obtained in ten weeks or less, in more than half of the cases. The tolerance was remarkable (less than 1% of cases had to interrupt treatment). This product represents an important progress as compared to Tretinoin alone. No other local or systemic therapy, especially long term antibiotherapy, is required.

[Leg ulcer. Vascular and thrombosis factors. Each responsibility of those factors? (author's transl)]. / Ulcères de jambe. Facteur vasculaire et facteur de thrombose. Quelle part de responsabilité peut-on attribuer à chacun?

In this paper the authors try to specify the leg ulcers physiopathology. They have first studied the vascular deficits, and they are able to conclude that this deficit is not the only factor responsible for the thrombosis. They try to rediscover the factors which could lead to the thrombosis, on the created local conditions (circulatory slackening, cooling, ischemia), by using clinical and biological "check-ups" as well as an exploration of the clotting. In many patients we find an anomaly such as: clotting "check-ups" disturbance, thrombocyte hyperaggregability, fibrinolysis deficit, antithrombin III deficit, cryoprecipitate, circulating immune complexes, hepatic "check-up" alteration. It is difficult to establish an accurate relation between these anomalies and a thrombosis but the frequent existence of such anomalies makes us think that they play a part in the ulcerations coming-up.

[Paraneoplastic acrokeratosis]. / Paraneoplatische Akrokeratose.

Paraneoplastic acrokeratosis is a distinctive dermatosis observed only in patients with either carcinoma of the upper respiratory and digestive tract or with metastatic lymphnodes in the cervical or mediastinal region. The characteristics of this dermatosis are: acral beginning, erythematous, squamous and hyperkeratotic plaques with centripedal spreading and healing only after successful treatment of the carcinoma. An allergic or toxic skin reaction to a substance formed by the tumor cells is discussed as causative agent. The author gives a review of the symptoms, the course of the disease, of histological and biochemical data and of the differential diagnosis as reported in the literature.

[Dermatology and polyposis of the gastro-intestinal tract (author's transl)]. / Dermatologie et polypose digestive.

The authors study three rare syndromes which are characterized by the association of cutaneous manifestations with an intestinal polyposis: Gardner's syndrome, Peutz-Jeghers-Touraine's syndrome, Cronkhite-Canada's syndrome. The Gardner's syndrome is transmitted with an autosomal prevalence, and its vital prognosis remains very porr. It is characterized by the association of various cutaneous manifestations such as fibromas, freckles, etc. with osteomas, neuro-fibromas and polyps of the large bowel. Its severity is related to the very early malignant degeneration of digestive polyps. The Peutz-Jeghers-Touraine's syndrome is transmitted in an autosomal prevalence and its vital prognosis is benign. The cutaneous manifestations are the very early occurrence of lentigines on the face, around the hiatus, and on the lips. The polyps are situated on the small bowel, and are the source of important functional phenomenons; their malignant change is rare. The Cronkhite-Canada's syndrome is rare. Its etiology is unknown and its prognosis is very poor. Its manifestation is the association of more or less wide-spread cutaneous pigmentations, alopecia, and onyxis with a digestive syndrome secondary to a pseudo-polyposis which is the origin for afecal and serous diarrhea, a cause for very severe denutrition. The diagnosis and the treatment of these three syndromes are discussed.

[Immunodiffusion and immunoelectrophoretic techniques applied to psoriasis (author's transl)]. / Techniques d'immunodiffusion et d'immuno-électrophorèse appliquées au psoriasis.

Serum and scales of skin obtained from normal and psoriatic subjects are tested and estimated by immune diffusion and immune electrophoresis technics. The authors relate technics to produce rabbit's antibodies towards psoriatic serums and extracts of skin. Results coroborate the quantitative modifications of immunoglobulins and show in addition the presence of multiple precipitations lines in the alpha and gamma regions. Lastly, in psoriatic scales a globulin is found, which is not present in normal scales or normal serums.

[Dermatosis caused by bone graft material (author's transl)]. / Manifestations cutanées provoquées par le matériel métallique d'ostéo-synthèse.

Cases of dermatosis caused by surgical implants are not infrequently observed. They are represented by many clinical forms. The pathology slides most often reveal a more or less dense dermal infiltration associated with signs of allergic angeitis. The pathophysiology is described as an intermediate or retarded hypersensibility or continuous non-specific antigen stimulation. The diagnosis is confirmed by the cure following removal of the surgical implants since the epicutaneous tests are not always fiable. We noted two patients whose clinical profile ressembled that of hematodermie.
