Mucosal leishmaniasis due to Leishmania (Viannia) panamensis in Colombia.: Clinical characteristics

The Leishmaniases are a group of diseases whose clinical presentation is in part determined by the infecting species. Until recently, mucosal leishmaniasis was attributed exclusively to Leishmania (Viannia) braziliensis; however, the capacity of other species of the subgenus Viannia to invade mucosal tissue has been documented. This report examines the clinical characteristics of 23 parasitologically diagnosed patients with mucosal leishmaniasis due to L. (V.) panamensis from the Pacific Coast of Colombia seen at CIDEIM between 1985 and 1996. Most of the mucosal lesions 74% (17 of 23) were mild, with a short time of evolution (median = 2.5 months) and were present concomitantly with an active cutaneous lesion in 61% (14 of 23) of the cases. The simultaneous presentation of mucosal and active cutaneous lesions contrast with classical descriptions of mucosal leishmaniasis caused by L. (V.) braziliensis, and highlights the importance of early diagnosis of mucosal disease by the examination of mucosa in all cases of cutaneous leishmaniasis.
