Forty-one specimens taken from lesions in the post-cricoid region of patients with the Paterson-Kelly syndrome have been examined. Most webs consist of normal oesophageal mucosa which may be associated with underlying muscle and nerve lesions. Strictures also show a chronic non-specific inflammation often with epithelial changes and sometimes squamous carcinoma. Other lesions observed clinicall...

Investigations of wound healing of the cricoid cartilage, its epithelium and subepithelial layer were performed in an experimental model.
