[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.

[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.

[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.

[Hereditary Sipple syndrome (author's transl)]. / Syndrome de Sipple héréditaire.

This entity, isolated by Gorlin, is characterized by the presence of cutaneous and mucous neuromas, facial disfiguration resembling acromegalia as well as morphological changes to the extremities similar to those produced by Marfan's disease. These factors are also associated with multiple endocrinological neoplasms type II of Sipple's syndrome. In other words, malignant tumors developing from thyroid "C" cells as well as from bilateral benign pheochromocytoma (neoplasias which derive from the A.P.U.D. system). It is considered to be hereditary in nature and transmitted as a dominant trait. Its evolution is triphasic, and the prognosis is extremely dismal. There may exist incomplete or benign forms, in the course of which the endocrinological neoplasms may appear very late or not at all. Generally, the diagnosis is easy. This entity can be calssified with other diseases stemming from the neural ridge, in other words "neurocristopathies" but in spite of these similarities with disease of the same embryological origin, it would seem that this particular entity is genetically autonomous. The only effective treatment is surgical, for thyroid neoplasms, as well as neoplasms occurring in the medullo-adrenal glands. It should be noted that this line of treatment must be undertaken with the utmost precaution.

[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.

[Vogt-Koyanagi-Harada disease. About two observations (author's transl)]. / Maladie de Vogt-Koyanagi-Harada. A propos de 2 observations.

After a reminder of clinical symptoms and development of the V.-K.-H. disease, some histological and clinical observations are related. The clinical observations are very characteristic of the V.-K.-H. disease. There are only two notable points: in both observations, a very low lymphocytic reaction to phytohemaglutinin and in the first observation, the presence of an anemia with parallel evolution to the uveitis. The histological examination of the depigmented area shows an infiltrate as described by Perrot, around the involved area in vitiligo. Ultrastructural study identifies 250 angströms wide particles that appear to be particles of alpha-glycogene, well developed amyelinic endings, and lastly, lymphocytoid cells closely joined with dendritic cells having internal granulations. These aspects have already been found in the iris by the Japanese authors, and they evoked an immunological mechanism.

[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.

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.
