title: Ulcerated upper lip tumour: diagnostic procedure.
abstract: A Mediterranean Spanish woman, aged 56 years and in good health, presented with a nodule above her upper lip, which had rapidly evolved to central ulceration with crusting. As part of the work-up, samples were taken for microbiological and histopathological investigation. At the follow-up appointment the lesion had almost disappeared and a small fibrotic area of scarring remained. The diagnostic procedure to distinguish between localised cutaneous leishmaniasis and keratoacanthoma, both characterised by rapidly growing nodules on the face, is presented in this case-based article.
