LRC is characterized by slowly progressing lesion(s) that appear after a variable period of time, from months to years, in or around the scar of an apparently clinically healed sore.<\/jats:p><jats:p><jats:bold>Patients and methods\u2002<\/jats:bold> Six patients are reported who presented with crusted, papular lesions located on the edge of a healed scar, with a mean of 18.2\u00a0months of slowly progressive evolution. The isolated strains of <jats:italic>Leishmania<\/jats:italic> parasites were characterized by enzyme electrophoresis. Eleven enzyme systems were assayed. Skin biopsies from the active border of the lesions were taken for histopathology.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> Tissue sections showed a granulomatous, lymphohistiocytic, dermal infiltrate containing Langhans\u2019 giant cells. The anamnestic data, together with the clinical and histopathologic findings, support the diagnosis of LRC. The isoenzyme profile of <jats:italic>Leishmania<\/jats:italic> parasites isolated from five of the six patients identified them as <jats:italic>Leishmania<\/jats:italic> (<jats:italic>Viannia<\/jats:italic>) <jats:italic>panamensis<\/jats:italic>.<\/jats:p><jats:p><jats:bold>Conclusions\u2002<\/jats:bold> These findings are the first reported evidence of LRC within the clinical spectrum of American tegumentary leishmaniasis in Ecuador, and of its causative agent. The existence of LRC has future implications for both disease treatment and vaccine
