[Two cases of eruptive pyoderma gangrenosum associated with cocaine use].
We present the cases of 2 regular cocaine users aged 30 and 37 years who developed a cutaneous condition with an identical presentation and a similar clinical course. The lesions first appeared as eruptions on the back and then spread to other parts of the body. They consisted of painful inflammatory nodules that developed into abscesses and ulcers that grew outwards. They had a granulomatous base and irregular violaceous edges. The results of histopathologic studies were compatible with the clinical diagnosis of pyoderma gangrenosum, and additional tests ruled out underlying diseases. After several therapeutic failures with usual treatments, the patients responded quickly to infliximab after interrupting their cocaine consumption. The association between pyoderma gangrenosum and cocaine use was clear as both suffered clinical relapses at the same time as they started using the drug again.
