Cutaneous toxoplasmosis.

Nine patients with cutaneous toxoplasmosis had slowly regressing erythema-multiforme-like eruptions or lichenoid, papulonodular and purpurictelangiectatic disorders. The most common histologic finding was subacute histiolymphocytic perivasculitis with frequent demonstration of the parasite. Another group of patients showed similar clinical and histological findings, but the parasite was not evidenced in these.
