The paper reports a study of 34 sweat gland tumours, 3 of which were malignant. In line with recent publications on the topic, no immunophenotype is identified which could differentiate between pathologies of an eccrine as opposed to apocrine origin. With regard to the possibility of distinguishing malignant from benign tumours, the paper reconfirms the importance of CEA which is the only immunomarker common to all the malignant forms examined.
