Abstract
Mycobacterium haemophilum and crusted scabies are rare cutaneous diseases reported in distinct immunocompromised hosts. M. haemophilum is a skin and soft tissue infection, whereas crusted scabies is an infestation of the skin. Whereas scabies infestation is readily diagnosed, M. haemophilum infection poses a diagnostic challenge due to its rarity as well as varied clinical and histologic presentations. Although both scabies infestation and M. haemophilum have been reported in the literature separately, to our knowledge no previous reports have described these diseases occurring simultaneously in an iatrogenically immunosuppressed patient. We report herein a rare case of concomitant M. haemophilum and scabies infestation in a 38-year-old woman with dermatomyositis on multiple immunosuppressive agents.
Highlights
Mycobacterium haemophilum is a slowgrowing nontuberculous mycobacterium that causes skin and soft tissue infections in immunocompromised hosts.[1]
While scabies infestation can be diagnosed with a scraping and direct microscopy, M. haemophilum infection poses a diagnostic challenge due to its broad clinical presentation, nonspecific histopathological findings, and culture requirements.[1,4]
We report a case of concomitant M. haemophilum infection and scabies infestation in a 38-year-old woman on multiple immunosuppressive agents for dermatomyositis
