Mucin histochemistry in tumours of colon,ovaries and lung

Aim: to confirm the presence of mucin production using haematoxylin and eosin (h&e) stain as the gold standard and to describe the types of mucins produced in tumours of lung,colon and ovaries using various types of histochemical techniques. methods: the resection specimens and biopsies from tumours of colon (n=16),ovaries (n=13) and lung (n=5) were included and stained with h & e to determin the histological diagnosis for selecting tissues with mucin production. slides were stained with pas,alcian blue,high iron diamine - alcian blue,meyer's mucicarmine and alcian blue - pas to demonstrate the mucin production and to identify types of mucins. results: in the present study we observed predominance of acid mucins over neutral mucins. in addition in these cases we observed sulphomucin predominating over sialomucin. conclusion: mucin histochemistry can effectively determine the types of mucins.
