title: Pseudotumors and mimickers of malignancy  of the head and neck pathology.
abstract: We are summarizing some of the difficult pitfalls in tumors of the head and neck, which we have encountered in our biopsies referred for consultation as well as from our routine praxis in the last 20 years. Shortly we are presenting the following lesions of head and neck: multifocal sclerosing thyroiditis, mucoepidermoid carcinoma of the thyroid, solid cell nests, Chievitz organ, rhomboid glossitis, ectopic parathyroid, signet ring cell change of salivary glands, mucocele, epithelial misplacement of the vocal cord squamous cell epithelium, and angiomatoid nasal polyps.
