A Case for Diagnosis (Purpura Annularis Telangiectodes?). Presented by Dr. S. E. Sweitzer, Minneapolis.
A. D., a 70 year old white man, was admitted to the Minneapolis General Hospital on Jan. 11, 1944, complaining of ringlike red spots on the right leg and in the axillas of about two weeks' duration. The lesions began as small rings on the thighs, increased in number and in size and spread to the chest. They did not itch, nor were they painful. The lesions when first seen varied from plaques 1 cm. in diameter to rings about 4 cm. in diameter. These did not blanch on diascopy. The patient had severe stasis dermatitis and resultant scarring and large varices. One lesion on the medial portion of the right thigh was blanched with ethyl chloride, and after the resultant erythema subsided it was gone.
Serologic reactions for syphilis were negative. Repeated
