ABSTRACT
Lobomycosis or lacaziosis is a chronic granulomatous fungal infection caused by Lacazia loboi. Most cases are restricted to tropical regions. Transmission is believed to occur through traumatic inoculation in the skin, mainly in exposed areas. It is characterized by keloid-like nodules. There are only a few hundred cases reported. The differential diagnoses include many skin conditions, and treatment is difficult. The reported case, initially diagnosed as keloid, proved to be refractory to surgical treatment alone. It was subsequently approached with extensive surgery, cryotherapy every three months and a combination of itraconazole and clofazimine for two years. No signs of clinical and histopathological activity were detected during follow-up.

Lacaziosis or Jorge Lobo's disease is a fungal, granulomatous, chronic infectious disease caused by Lacazia loboi, which usually affects the skin and subcutaneous tissue. It is characterized by slow evolution and a variety of cutaneous manifestations with the most common clinical expression being nodular keloid lesions that predominate in exposed areas. We report the case of a patient who had an unusual clinical presentation, with a single-plated lesion on the back. Histopathological examination confirmed the diagnosis of Lacaziosis.

There are six diseases that WHO considers as the major threat in developing countries, leprosy, filariasis, malaria, schistosomiasis, Chagas disease and leishmaniasis; and of these only malaria does not present skin lesions. These diseases are among the so called tropical diseases found in countries of tropical climate, usually infections and infestations considered exotic and rare in European and North American countries. It is extremely important for doctors of all countries to be able to provide correct pre travel counseling and to make early diagnosis and treatment, thus avoiding dissemination of these dieases to non endemic areas. The authors review some important tropical diseases seen in Brazil, as paracoccidiodomycosis, lobomycosis, myiasis, tungiasis, and cutaneous schistosomiasis and discuss new information about them.
