RESUMEN
Se describe el caso clínico de un paciente de 34 años de edad, quien acudió a consulta de Dermatología por presentar máculas eritematosas pruriginosas generalizadas. A los 3 meses con tratamiento específico comenzó a presentar febrículas vespertinas y adenopatías cervicales dolorosas, por lo que se indicó una baciloscopia en ambos codos y pabellones auriculares, pero no se halló el Mycobacterium leprae; además se realizó biopsia por aspiración con aguja fina de un ganglio cervical, cuyo resultado reveló una tuberculosis ganglionar. Finalmente se diagnosticó una coinfección por lepra y tuberculosis ganglionar, dos enfermedades producidas por el Mycobacterium, cuya coexistencia es rara.
