Mycobacterium abscessus infection in a patient with ornithine transcarbamylase deficiency and liver transplant.

Rapidly growing mycobacteria, including Mycobacterium abscessus, have become a common cause of post-procedural infections and are notoriously difficult to diagnose and treat. Here, we report a 10-month-old male status post-orthotopic liver transplantation due to ornithine transcarbamylase deficiency who presented with a 4-month history of hypertrophic and friable granulation tissue of surgical wounds refractory to treatment with broad spectrum antibiotics and surgical debridement. Skin biopsy and tissue culture yielded a diagnosis of M abscessus infection that demonstrated excellent clinical response to appropriate antibiotic and surgical treatment.
