Mycetomas: an epidemiological, etiological, clinical, laboratory and therapeutic review.

Mycetoma is a chronic suppurative disease of the skin and subcutaneous tissue, characterized by a symptomatic triad: tumor, fistulas and grains. It can be caused by fungi (eumycetoma) and bacteria (actinomycetoma), with similar clinical features. Diagnosis is based on the clinical presentation and identification of the etiological agents in the tissue, by mycological/bacteriological, histopathological and immunohistochemical tests.

Bullous pemphigoid in a 3-month-old infant: case report and literature review of this dermatosis in childhood.

Bullous pemphigoid is an autoimmune subepidermal blistering dermatosis that is uncommon in childhood. We report a case of a female infant, 3 months old, which presented clinical and laboratory data for the confirmatory diagnosis of bullous pemphigoid. The authors used immunohistochemical staining for collagen type IV that allowed the differentiation of bullous pemphigoid from other subepidermal bullous diseases.

Study of dermatoses in kidney transplant patients.

Objectives: to evaluate the frequency of dermatoses in kidney transplant recipients.

Methods: kidney transplant recipients with suspected dermatoses between March 1st 2009 and June 30th 2010.
