Recurrent erysipelas caused by group B streptococcus organisms.

Group B beta-hemolytic streptococcus (GBS) has emerged as a major cause of neonatal infections. Serious GBS infections in adults occur most frequently when predisposing illness is present. Recurrent erysipelas caused by GBS is reported in a woman who had chronic lymphedema after a radical hysterectomy and radiation therapy. Type III GBS was identified from cultures of vulvar vesicles, vaginal mucosa, and blood. Prophylactic penicillin V potassium therapy prevented further episodes of erysipelas. Group B beta-hemolytic streptococcus should be considered a possible cause of erysipelas or cellulitis.

Cutaneous Mycobacterium kansasii infection presenting as cellulitis.

An immunocompromised renal transplant patient developed a cellulitis-like lesion on the leg. This lesion and subsequent periarticular lesions proved to be due to Mycobacterium kansasii. Although cutaneous infection due to these microorganisms is rare, in selected cases it should be considered in the differential diagnosis.

Erysipelas.

Erysipelas is a superficial cellulitis that affects the skin and subcutaneous tissues. There is also prominent lymphatic involvement. Group A streptococci are the usual cause of this painful infection, but the responsible organisms cannot always be cultured from the fiery red, edematous, sometimes vesicular rash. A fulminating case developed in the left leg of a man whose veins had been harvested four months earlier for coronary artery bypass surgery.

[Pseudo-Kaposi sarcoma].

Case report about a 45 year old man with hyperkeratotic papules and plaques on both lower legs now persisting for more than 20 years. After detection of arterio-venous shunts the initial clinical and histological diagnosis of Kaposi-sarcoma had to be replaced by the diagnosis of pseudo-Kaposi's sarcoma, a benign reactive process. In the pathogenesis of this disease arteriovenous shunts are of great importance.
