On microscopic examination, wide areas of atrophy, ulceration, and squamous metaplasia of the epithelial duct lining were seen, as was a surrounding patchy chronic inflammatory infiltrate with extensive fibrosis.
Epithelial duct metaplasia, proliferation, and atypia may be seen in CP in association with obstruction and inflammation, but severe dysplasia is not common and could represent a premalignant lesion that should alert the pathologist to submit more sections in order to exclude an adjacent invasive carcinoma.
In some areas, epithelial ducts that contained carcinoma were present within the sarcomatous neoplasm (figure 1, C).
