Intracellular acidic mucins and their identification in diagnostic cytology

Exfoliative, abrasive and aspiration cytology were increasingly relied upon for tissue diagnosis of tumours. The established histological stains for the differentiation of mucin and non-mucin-secreting tumours are not ideal for alcohol-fixed cytology smears and a more reliable cytological technique for the preservation and staining of intra-cellular acidic mucins using Alcohol Alcian Blue 8GX is presented.
