San Andrés y Providencia son islas colombianas en el mar de las Antillas. San Andrés tiene 68.283 habitantes y allí se han registrado casos de lepra en inmigrantes provenientes del interior colombiano. Providencia tiene 5.037 habitantes e, históricamente, los programas de salud no tenían registros de la enfermedad; no obstante, en el 2009 se confirmaron dos casos de lepra multibacilar histioide y, posteriormente, otros dos, lo cual representa una prevalencia de 8 casos por 10.000 habitantes y la la convierte en un sitio hiperendémico para lepra. Inicialmente, se diagnosticó lepra histioide en una niña de 14 años y, durante su estudio, se encontró la misma forma clínica de la enfermedad en su padre. Recientemente, se detectó lepra multibacilar en otro miembro de la misma familia y, lepra indeterminada, en una niña de otro núcleo familiar.El objetivo de este trabajo fue presentar estos casos clínicos ante la comunidad científica y los entes de salud pública, y llamar la atención de las autoridades de salud sobre la necesidad de establecer programas de vigilancia epidemiológica continua en la isla, incorporando las nuevas herramientas disponibles en el Programa de Control de la Lepra.

Conjugal leprosy Objectives Determining the occurrence of leprosy amongst couples and establishing the type of leprosy in index and secondary cases. Methods The characteristics of leprosy were studied between 1980 and 2000 in Atlántico Department located on the Colombian Caribbean Coast. Clinical histories of patients registered in the Leprosy Control Programme were reviewed. Clinical exams were performed and personal interviews carried out with couples suffering from leprosy. Results Twenty-six married couples were found to be suffering from leprosy, representing 5,4 % of leprosy cases detected during the study period. They were aged from 20 to 89. 65,4 % of the index cases were men and 22 (84,6 %) were multibacillary, lepromatous cases; two had indeterminate leprosy and two were suffering from tuberculoid leprosy. Sixty-one percent of the secondary cases were paucibacillary patients, 42 % of them being tuberculoid. No paucibacillary cases were associated with multibacillary leprosy in the couples. Only two couples had consanguinity. None of the couples had had leprosy at the time of being married. The time between leprosy being detected in index cases and the disease being detected in secondary patients varied from 5 to 40 years. Disabilities were more common in the feet and to a higher degree in lepromatous index cases who had had the disease for a longer time than the secondary cases because these were more frequently paucibacillary patients who had a disease having shorter evolution. Conclusions In spite of ongoing, prolonged contact, conjugal leprosy is not frequent and requires several years to develop in the second person. Lepromatous leprosy in index cases was more frequently associated with leprosy in the couple. When the primary case was paucibacillary, no multibacillary leprosy occurred in the secondary case.

La conidiobolomicosis es una micosis subcutánea que se localiza generalmente en la línea media facial; es causada por un hongo saprófito de suelos y vegetales secos, propio de regiones intertropicales, que afecta principalmente a hombres adultos. El agente etiológico Conidiobolus coronatus pertenece a la clase de los Zigomicetos, orden Entomoftorales; se caracteriza por hifas cortas y gruesas, generalmente aseptadas, que crece entre 30°C y 37°C y produce granulomas nasales. Se informan a continuación los hallazgos histológicos de un caso de conidiobolomicosis en un paciente de 31 años de raza negra, natural y procedente de la región de Urabá, quien presentaba deformidad mediofacial con edema de nariz, labio superior e imágenes polipoides en senos maxilares con destrucción del tabique nasal. La biopsia demostró inflamación granulomatosa necrosante difusa en la dermis profunda e hipodermis asociada con eosinófilos y fenómeno de Splendore-Hoeppli, en cuya zona central se ubicaban espacios aparentemente vacíos que contenían el hongo que no se tiñó con HE, pero que sí lo hizo con las coloraciones de PAS y Grocott lo cual permitió la observación de hifas de paredes gruesas y rígidas, con torsión central y extremos cónicos.Palabras clave: conidiobolomicosis, Conidiobolus coronatus, micosis subcutáneas, entomoftoromicosis, rinoentomoftoromicosis, cigomicosis. Conidiobolomycosis: a case report with histophathologic findingsConidiobolomycosis is a subcutaneous mycosis of the facial midline affecting primarily adult males. It is caused by the saprophytic fungus, Conodiobolus coronatus, present in soils and dried vegetables, characteristic of intertropical regions. C. coronatus belongs to the class Zygomycetes, order Entomophthorales; it is a fungus composed of thick, short hyphae that grows at temperatures between 30°C and 37°C and causes nasal granulomas. The histologic findings are described of a case of conidiobolomycosis in a 31-year-old male, born and resident in the Urabá region of Colombia. He presented with a mid-facial deformity of the nose and upper lip edema, and polypoid images in the maxillary sinuses with destruction of the nasal septum. The biopsy revealed a diffuse inflammatory lesion located in the deep dermis and in the hypodermis corresponding to a necrotizing granuloma. Associated eosinophils and the presence of the Splendore-Hoeppli phenomenon were noted in the vacant central zone which apparently corresponded to location of the fungal hyphae. They did not stain with HE stain, but reacted to the PAS and Grocott staining techniques and appeared as rigid, thick-walled hyphae, centrally twisted and with cone-shaped endings.
