Immunoglobulin A pemphigus associated with immunoglobulin A gammopathy and lung cancer.

Immunoglobulin (Ig)A pemphigus is a rare disease marked by a vesiculopustular eruption characterized by intercellular IgA deposition in the epidermis. It has clinical and histopathological heterogeneity and encompasses two subgroups: subcorneal pustular dermatosis type and intraepidermal neutrophilic IgA dermatosis type. IgA pemphigus has been rarely associated with monoclonal IgA paraprotein, myeloma and B-cell lymphoma in the past.

Human immunodeficiency virus infection and pregnancy.

Human immunodeficiency virus infection profoundly affects the medical community and is spreading rapidly in women of childbearing age worldwide. Transmission of HIV from mother to child can occur in utero, during labor, or after delivery through breast-feeding. Most of the infants are infected during delivery.

Polymorphic eruption of pregnancy.

Polymorphic eruption of pregnancy (PEP) is a benign, self-limiting, pruritic disorder of pregnancy, which usually affects the primigravida during the last trimester or immediately postpartum. Its pathogenesis is unclear and its clinical manifestations are variable, leading frequently to an incorrect diagnosis. In cases of PEP the histological findings are nonspecific and the laboratory results, including direct immunofluorescence (DIF) and indirect immunofluorescence (IIF), are negative.

Early cutaneous alterations in experimental sepsis by Pseudomonas aeruginosa.

Background: To evaluate whether histopathologic findings of skin in sepsis by Pseudomonas aeruginosa correlate with the clinical course.

Methods: Histological alterations after bacterial challenge by one susceptible (A) and two multidrug-resistant isolates (B and C) of P. aeruginosa were studied in 18 rabbits.
