Thiopronine-induced herpetiform pemphigus: report of a case studied by immunoelectron microscopy and immunoblot analysis.

We report a case of herpetiform pemphigus induced by thiopronine. Direct immunoelectron microscopy performed on peribullous skin showed IgG deposits predominantly located in the extracellular portion of desmosomes. By immunoblot analysis using bovine tongue extracts as the antigen, the patient's serum recognized a 160-kDa polypeptide which comigrated with desmoglein I. This study underlines the contribution of immunoblot analysis to the diagnosis of atypical cases of pemphigus, and confirms that herpetiform pemphigus may be a clinical variant of pemphigus foliaceus.

Subcutaneous changes in dermatomyositis.

We report the case of a 42-year-old woman with concomitant panniculitis and dermatomyositis. Painful, indurated lesions on the buttocks, thighs, arms, abdomen and breasts were associated with proximal muscle weakness. Skin biopsy revealed lobular panniculitis, and vacuolar degeneration of epidermal basal cells. Direct immunofluorescence was negative. Serum muscle enzyme (creatinine-phosphokinase) levels were elevated, and electromyography demonstrated a myositic process. Muscle biopsy showed an inflammatory myositis. These results were consistent with dermatomyositis associated with panniculitis. Only five cases of this association have been reported previously. The relationship between these two conditions is discussed.
