Ecthyma gangrenosum: A case report in a child with acute lymphoblastic leukaemia

AimWe present a case of Ecthyma gangrenosum (EG) affecting left thigh in a child with acute lymphoblastic leukaemia (ALL) with an aim to raise awareness about this condition.Case presentationA 7-year-old female child who presented with lethargy, pallor and lumps to inner lip was diagnosed with B-cell precursor ALL. She was started on treatment as per UKALL 2011 guidelines Regime B. On day 28, she developed neutropenic sepsis along with a new lesion in her left thigh. She was started on intravenous Meropenum, Gentamicin and Caspofungin. The clinical diagnosis of EG was made based on lesion progression, positive blood and wound swab & tissue cultures for Pseudomonas aeruginosa and patient's immunocompromised status. The wound healed with secondary intention following debridement. We present a series of photographs to demonstrate her remarkable improvement.DiscussionEG occurs in 1-30% of cases of Pseudomonas sepsis; other bacteria and fungi can be associated with this condition. It is identified more in oncology patients as seen in our patient. A multidisciplinary team approach should be provided in 3 stages with empirical antibiotics, followed by targeted antibiotics or antifungals & surgical debridement. Our patient was treated in similar fashion and made a good recovery.ConclusionIt is a rare skin condition associated with a high mortality. We suggest all clinicians to be vigilant about this condition to be able to provide accurate diagnosis and prompt treatment to improve the overall prognosis.
