The international standardization of diseases is a complex process that requires a specialized team. The aim of this work is to clarify and suggest some corrections for a probable misunderstanding during the translation of ICD-10 code A30 into Portuguese, in which the terms borderline and dimorfo (dimorphous) are used as different subcategories and not as synonyms; moreover, the designation lepromatosa (lepromatous) should be replaced by virchoviana (virchowian) considering that in Brazil, the word lepra (leprosy) was abolished from official texts by a Federal Act in 1995.
