[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.

Lectin application is used to study 12 cases of ichthyosis, 8 cases of Darier's disease and two of acrokeratosis verruciformis, establishing comparative patterns with normal skin.

[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.
