Intercellular IgA dermatosis.

We report three cases of intercellular IgA dermatosis (IAD) and review the literature. IAD is a spectrum of vesiculobullous or vesiculopustular diseases mediated by intercellular IgA deposition. The clinical picture may vary from a vesiculopustular eruption with centrifugal evolution mainly involving the trunk and extremities, to the typical picture of classic pemphigus variants (foliaceus, vegetans).

Dermatitis artefacta.

Self-inflicted dermatoses mainly refer to psychiatric disturbances such as psychoses, mental retardation, and personality disorders. Diagnostic clues are found in the nature and the evolution of the lesions as well as in the ambivalent combination of dependency on doctors and hostility toward them revealed in the patient's medical history. Management of dermatitis artefacta patients means dealing with the complex emotional issue of a basic antagonism in the dermatologist-patient relationship.

Livedo racemosa generalisata and stroke.

The authors describe three young female patients with generalized livedo racemosa and cerebral infarction. The radiologic and biopsy findings point to a widespread vasculopathy, involving small and mid-sized arteries. The histologic examination of the temporal artery biopsy in two patients gives additional evidence for a chronic endarteritis as possible underlying cause of this disease entity.

Reticular telangiectatic erythema after implantation of a pacemaker.

A case of a telangiectatic erythema appearing after implantation of a pacemaker is described. The eruption cleared completely after removal of the battery.
