title: Squamous cell carcinoma of the thyroid: a diagnostic dilemma.
abstract: Four cases of primary squamous cell carcinoma of the thyroid gland are reported. Thorough evaluation confirmed these lesions to be of primary thyroid origin rather than from metastasis or direct invasion from contiguous structures. These cases illustrate the aggressive nature of the disease and the propensity for local and distant metastases. The clinicopathologic data presented here underscore the challenge in diagnosis and treatment of this rare entity.
