Jorge Lobo's Disease (JLD) is a chronic granulomatous cutaneous mycosis caused by Lacazia loboi. The most typical lesions are keloid-like growths preferentially located on limbs and ears. To the best of the authors' knowledge, only one labial case has previously been reported. We describe the case of a man who presented with a left-sided papulonodular lesion of 10 years' duration on the vermillion border of the upper lip. A successful surgical resection of the lesion was performed and there was no recurrence in eight years of follow-up.

A 55-year-old, retired, male, dark-skinned farmer (Acará, PA) who had lived in Belém (PA) for 36 years presented in 1998 with a mildly pruriginous lesion on the upper lip of 10 years' duration. The lesion, which was located on the left of the upper lip, was dome-shaped and papulonodular, measured 1.0 cm and had a central depression and firm consistency. Jorge Lobo's disease (JLD) was confirmed by direct and histopathological examination. General clinical tests and additional tests requested (complete blood count; ESR; blood glucose level; glycosylated hemoglobin; serum levels of immunoglobulins and complement; anti-HIV antibodies; cell immunology; and urinalysis) did not show any alterations worthy of note. A wedge excision of the lesion was performed. Surgical margins were clear and there was no recurrence of the lesion in eight years.
JLD is a chronic granulomatous infection produced by the yeast-like fungus Lacazia loboi 1 that primarily affects farm laborers between the ages of 21 and 40 years.2 To the authors' knowledge, there is only one case of a patient with a lesion on the lip among the 490 cases recorded worldwide up to 20063.4
