The prevalence of infections by nontuberculous mycobacteria (NTM) has steadily increased over the past decades, especially in immunocompromised patients.

Case presentation

We present a patient with IgA-deficiency and mixed cutaneous infection by two slowly growing mycobacteria, Mycobacterium (M.) haemophilum and M. kansasii.


Cutaneous M. haemophilum infections most often result from HIV or transplantation-associated immunosuppression. Rarely, M. haemophilum may also infect healthy patients or iatrogenically immunosuppressed patients without transplantation. M. kansasii is one of the most frequent NTM and large awareness exists about its involvement in human diseases. Mycobacterial diagnosis of cutaneous infections should be considered in long-lasting skin lesions.
