Strongyloides stercoralis infection in allogeneic stem cell transplant: a case report and review of the literature

Strongyloides stercoralis infections may be documented in low-endemicity areas, particularly in immigrants from endemic areas. The case of a patient from Bangladesh, an immigrant to Italy who developed a S. stercoralis infection after allogeneic stem cell transplant, is described, and 7 further cases are reviewed. Because of the atypical clinical presentation, the low predictive role of the eosinophil count, and the low sensitivity of the microbiological tests, diagnosis of strongyloidiasis is a challenging problem. When a case of S. stercoralis infection is suspected, previous exposure may be the only clue to guide the diagnostic approach.
