ABSTRACT
Resumen La cromoblastomicosis es una infección fúngica de la piel y del tejido subcutáneo, de evolución crónica, causada por hongos dematiáceos que se caracterizan por presentar melanina en su pared celular. La enfermedad se presenta en todo el mundo, principalmente en regiones tropicales y subtropicales. En Chile, solo hay un reporte de caso humano hace más de 30 años. Se presenta el caso de un varón de 46 años, haitiano, residente en Chile, con placas verrucosas en la zona tibial anterior de un año de evolución. El diagnóstico de cromoblastomicosis se confirmó al observar células muriformes en la histopatología y colonias dematiáceas en el cultivo micológico; además, en la miscroscopía directa se observaron conidias compatibles con Fonsecaea spp. Luego de seis meses de tratamiento con antimicóticos sistémicos y crioterapia, se logró la remisión completa de las lesiones.
Abstract Chromoblastomycosis is a fungal infection of the skin and subcutaneous tissue, of chronic evolution, caused by dematiaceous fungi. The disease occurs worldwide, mainly in tropical and subtropical regions, but in regions like Chile there is only one report of a human case more than 30 years ago. We present the case of a 46-year-old Haitian man, resident in Chile, with verrucous plaques in the right anterior tibial area of one year of evolution. The diagnosis of chromoblastomycosis was confirmed when muriform cells and dematiaceous colonies were observed in the histopathological analysis and the direct microscopy, respectively. After six months of treatment with systemic antimycotics and cryotherapy, complete remission of the lesions was achieved.

Abstract Sweet syndrome is an inflammatory disease characterized by fever, neutrophilia, papules and erythematous plaques, and a skin neutrophilic infiltrate. Syphilis has been reported among the infectious causes of Sweet syndrome. Syphilis can present atypical manifestations; a rare presentation is nodular syphilis, characterized by nodules with granulomas and plasma cells at histopathology. This case report presents a 20-year-old woman patient, with plaques and nodules, and systemic symptoms. The histopathological exam revealed both non-tuberculoid granulomas and a dense infiltration of polymorphonuclear neutrophils in the dermis. These findings, plus laboratory abnormalities, characteristic of both conditions, were conclusive for Sweet syndrome and nodular syphilis association.

El nevo sebáceo o nevo de Jadassohn es un hamartoma cutáneo congénito poco frecuente formado por múltiples estructuras cutáneas. Presenta potencial de transformación a una variedad de neoplasias epidérmicas benignas y malignas, que suelen presentarse de manera individual. Si bien esta descrito en la literatura, es inusual el desarrollo de más de una neoplasia sobre un nevo sebáceo. En esta publicación se presenta el caso de un hombre de 62 años con una lesión de 3 años de evolución, cuyo estudio histopatológico demostró la presencia de un carcinoma basocelular y un siringocistoadenoma papilífero sobre un nevo sebáceo de Jadassohn.
Nevus sebaceous of Jadassohn is an infrequent cutaneous congenital hamartoma, formed by multiple cutaneous structures. It possesses a transformation potential to benign and malignant epidermic neoplasms, that usually present individually. Even though a few cases have been published, the coexistence of two or more tumors is rare. We hereby present the case of a 62 years old male, with a nevus sebaceous of Jadassohn history, that after excisional biopsy showed the presence of a basal cell carcinoma associated to a syringocystoadenoma papilliferum.
