title: Ecthyma gangrenosum: a rare cutaneous manifestation caused by pseudomonas aeruginosa without bacteraemia in a leukaemic patient--a case report.
abstract: Ecthyma gangrenosum is a rare and invasive cutaneous infection caused by Pseudomonas aeruginosa in the majority of cases, typically affecting immunocompromised patients, particularly those with neutropenia. We report a rare case of ecthyma gangrenosum in the absence of bacteraemia presenting as a solitary necrotic ulcer in a female patient with acute lymphoblastic leukaemia. A culture from the ecthyma lesion revealed the presence of Pesudomonas aeruginosa, but the results of repeated blood cultures were negative. The patient responded well to amikacin to which the isolate was susceptible in vitro. Considering high rate of mortality, early diagnosis and prompt effective treatment is mandatory.
