Abstract :
A 61-year-old opium addicted male admitted to the hospital with a history of a fairly good health, until four weeks before his ad- mission, when he became febrile with an axillary temperature of 38.4 °C. Then he developed tender, erythematous and indurated plaques over the front of his both knees, which became ulcerative in a few days. Thereafter, the lesions spread to his right thigh. Physical examination at the time of admission revealed two indu- rated and ulcerative satellite plaques with a violaceous base and sharp, but irregular borders, surrounded by petechiae in several areas on both his knees and the anterior aspect of his right thigh. The lesions measured from 5 to 18 cm in diameter. Both feet were edematous(Figure 1 A B). Axillary temperature was 38 °C, heart rate was 104, and blood pressure was 124/78 mmHg.
