[Palmoplantar and disseminated porokeratosis: immunohistochemical study].

We present a new case of porokeratosis plantaris palmaris et disseminata (PPPD), observe in it a histological picture of cornoid lamella in palms, soles, arms, legs and trunk. In this dermatosis, mediant lectins and involucrin to establish keratinocytes alteration. The immunohistochemical studies have reveals not normal formation in the envelope cornea, and fundamentally D-galactose show a marked diminution in the cell membrane.

[Ultrastructural study of a case of argyria].

The authors studied by transmission electron microscopy a case of cutaneous argyria. Found round and oval forms into which there are a silver granules forming rings. Those images sequencied permit hypothesized that the winning of the solved silver by phagocytes into which are precipitate and eliminate out of the cell.

Argyria↗

[Lectin staining of a Merkel cell tumor].

The authors studied a Merkel's cell tumor with lectins. There is pattern of normal epidermis, but we see the N-acetyl-glucosamine an oligosaccharide not present in epidermis.

Acetylglucosamine↗

[Immunologic parameters in patients with acuminata condylomas].

A study is made of the state of cell and humoral immunity in patients with genital warts. The results show an increase in the T-suppressor lymphocyte population (T8+) (p less than 0.011) of these patients, which reduces the T-helper/T suppressor ratio (T4 +/T8 +). No alterations are observed in the humoral immunity on analyzing seric immunoglobulin concentration (IgA, IgG, IgM), complement factors (C3, C4), or their functionality (CH50).

[Risk factors for the recurrence of spinocellular epithelioma. Study of 650 cases].

An evaluation is made of the clinical and histological parameters of 650 cases of spinocellular epithelioma. The statistical analysis shows tumor relapse to be related to tumor size, evolution time, relapse following previous treatments, earlier cutaneous lesions, Broders' grading, acantholysis, inflammatory infiltrate and type of treatment applied.

Biopsy↗

[Effect of bornaprine in localized hyperhidrosis].

Therapeutic action of bornaprine on localized forms of hyperhidrosis is studied in 12 patients. 50% improved after a week treatment. Other patients showed an acceptable change in the third or fourth week. Side effects only appeared in one patient.

Adult↗

[Changes in surface oligosaccharides in precancerous skin lesions].

The authors studied 5 cases of the actinic keratoses, 3 cases of the leukoplakia and 2 cases of the cutaneous horn with the lectins specifics on the oligosaccharides of the keratinocyte's membrane. The patterns in each disease are described according to grade of differentiation.

Cell Membrane↗

[Study of the circulating lymphocytes populations in systemic scleroderma, chronic discoid lupus erythematosus and dermatomyositis].

The authors studied the peripheral blood lymphocytes in any autoimmune diseases. In scleroderma the T-lymphocytes and ratio T4/T8 are decreased and B-lymphocytes are normal. In the LEDC the T-lymphocytes are decreased and B-lymphocytes are increased. In dermatomyositis the B-lymphocytes are increased and T-lymphocytes are decreased, the ratio T4/T8 is normal.

Chronic Disease↗

[Peripheral blood lymphocyte populations in 2 cases of Behçet syndrome].

The lymphocytes subsets in peripheral blood were studied in two patients with Behçet's syndrome. The finding about the decrease of T lymphocytes with the ratio elevated and specially the increase of B lymphocytes favors the hypothesis of predominance of the antibody formation over the cellular cytotoxicity.

Adult↗

[Immune staining of Paget's cells].

The authors studied with the technic of PAP a case of the Paget extramammary. The presence of the precursors of the human milk in these cells in a date for to thing than Paget extramammary is the origin eccrine or apocrine.
