Curso Internacional de Dermatopatología
Claves histológicas diagnósticas
Prof. Dr. D. J. Santa Cruz
Aun cuando el diagnóstico histológico en dermatopatología es un proceso deductivo complicado que integra información clínica, histológica y de laboratorio. A veces, algunos hallazgos diagnósticos pueden tener una sorpresiva capacidad diagnóstica. Algunos de ellos pueden ser marcadores únicos de una enfermedad, cuando otros son específicos de una familia de condiciones clínicas compartiendo la misma constelación de cambios histológicos.
