Leishmaniasis masquerading as pyoderma gangrenosum in a non-endemic area: A case report.

Pyoderma gangrenosum (PG) can be difficult to diagnose, leading to diagnostic delay which affects patient outcomes and increases health care utilization. Among different scenarios of diagnostic delay, atypical infections can mimic PG. Here, we present a case of extensive cutaneous leishmaniasis initially misdiagnosed as the superficial granulomatous variant of PG and describe diagnostic clues to aid in differentiation.
