Coexistence of two illnesses in the same patient may result in atypical manifestations of either or both diseases. A case of hepatitis B virus-related cirrhosis in a patient who presented with a pharyngeal mucosal mass lesion as a manifestation of superadded Leishmania infection is presented here. The clue to the diagnosis was the origin of the patient from an area highly endemic for leishmaniasis and the presence of unexplained polyclonal hypergammaglobulinaemia. The patient responded very well to therapy with amphotericin B with complete disappearance of the mucosal lesion.
