Pediatric Degos disease is rare, with only 36 cases reported in the medical literature. Classically the diagnosis has been established according to pathognomonic histopathologic findings, but when these features are not present, there may be a delay in diagnosis. We report the second congenital case of Degos disease, highlighting the clinical and dermoscopic findings.
La vacuna Bacillus Calmette-Guerin (BCG) que se administra a los recién nacidos de países con alta incidencia de tuberculosis puede ocasionar reacciones locales hasta infección diseminada en pacientes inmunocomprometidos. Reportamos el caso de un lactante varón de seis meses con antecedente de haber recibido vacuna BCG al nacer, y presentar cuadros infecciosos a repetición, nódulos violáceos blandos en tronco y extremidades con presencia de bacilos ácido alcohol resistentes (BARR) en la histopatología y en cultivo de piel; el estudio molecular reportó la presencia de Micobacterium bovis BCG. En la tomografía se observó opacidades intersticiales en pulmones y en el lavado gástrico se identificó BAAR. El estudio genético del paciente y de la madre reveló la presencia de mutación en el gen IL2RG confirmando el diagnóstico de inmunodeficiencia combinada severa, recibe tratamiento con inmunoglubolina humana y esquema antituberculosis con isoniacida, rifampicina y etambutol. Presentamos el caso por la implicancia en el pronóstico de vida de estos pacientes y por la necesidad de un diagnóstico preciso y oportuno.
Cutaneous expressions in cytomegalovirus infection are rare and their clinical manifestations in immunosuppressed patients are diverse; for example, ulcerative forms. Therefore, cytomegalovirus infection should be considered in the differential diagnosis of ulcers in immunosuppressed patients.We reported an immunosuppressed child with severe oral ulcerative lesions of torpid evolution, associated with cytomegalovirus infection, diagnosed by laboratory and histopathological examinations.
