Lobomycosis is a subcutaneous mycosis of chronic evolution caused by the Lacazia loboi fungus. Its distribution is almost exclusive in the Americas, and it has a particularly high prevalence in the Amazon basin. Cases of lobomycosis have been reported only in dolphins and humans. Its prevalence is higher among men who are active in the forest, such as rubber tappers, bushmen, miners, and Indian men. It is recognized that the traumatic implantation of the fungus on the skin is the route by which humans acquire this infection. The lesions affect mainly exposed areas such as the auricles and upper and lower limbs and are typically presented as keloid-like lesions. Currently, surgical removal is the therapeutic procedure of choice in initial cases. Despite the existing data and studies to date, the active immune mechanisms in this infection and its involvement in the control or development of lacaziosis have not been fully clarified. In recent years, little progress has been made in the appraisal of the epidemiologic aspects of the disease. So far, we have neither a population-based study nor any evaluation directed to the forest workers.

“…Así mismo, se ha propuesto que las células de Langerhans juegan un papel en la modulación del sistema inmune, ocasionando evasión en la presentación del antígeno fúngico. 2,4,5 Clínicamente, la enfermedad se caracteriza por lesiones pleomórficas. La presentación más común es la nodular, con una lesión sólida, localizada, de superficie lisa y brillante, semejante al aspecto de una cicatriz queloide.…”

“…En orden de frecuencia se describen: extremidades inferiores (32%), oído externo (25%), extremidades superiores (22%), cara (7%), diseminado (8%), sacro (3%), tórax (2%) y cuello (1%). 5 Dentro de las complicaciones puede existir restricción de movimientos en lesiones yuxtaarticulares, compromiso estético, infección secundaria por piógenos y degeneración hacia carcinoma epidermoide. 5,6 El examen directo de las lesiones revela levaduras de pared gruesa, refringentes, de doble contorno, que miden aproximadamente 5 x 14 µm.…”

RESUMENLa lacaziosis es una rara micosis cutánea y subcutánea, de evolución crónica, ocasionada por el hongo profundo Lacazia loboi. Ha sido descrita principalmente en regiones tropicales y subtropicales. Clínicamente se caracteriza por lesiones cutáneas de aspecto queloideano y progresión lenta. La enfermedad se presenta más frecuentemente en adultos varones que desempeñan actividades laborales en el campo. Se presenta el caso de un paciente masculino de 68 años, agricultor, con una dermatosis crónica localizada en el miembro superior derecho, caracterizada por una neoformación compuesta por múltiples lesiones nodulares de aspecto queloideano con una lesión satélite proximal. El diagnóstico histopatológico fue compatible con una lacaziosis. PALABRAS CLAVELacaziosis, lobomicosis, Lacazia loboi, micosis cutánea profunda, zoonosis. ABSTRACTLacaziosis is a rare cutaneous and subcutaneous mycosis, caused by the fungus Lacazia loboi. It has been mainly described in the tropical and subtropical regions. The disease has a slow and chronic clinical progression, characterized by keloid-like cutaneous lesions. Most cases have been described in adult males who work in the countryside. We present the case of a 68 year old male, farmer, with a chronic dermatosis localyzed in his upper right arm, composed of multiple nodular lesions of keloidian aspect with a proximal satellite lesion. The hystopathological diagnosis revealed a deep fungal mycosis compatible with lacaziosis.
