Thyroid cancer coexisting with Hashimoto's thyroiditis at King Khalid University Hospital, Saudi Arabia.

A retrospective record review was performed on all patients with thyroid carcinoma treated at King Khalid University Hospital (KKUH) during the period 1985 to 1993. Eighty one cases were identified of which 10 patients had coexistent Hashimoto's thyroiditis documented histologically. Of these ten patients, nine were females with a mean age of 32.2 years. There was one male aged 55 years. Five patients were treated with near total thyroidectomy while the others had subtotal thyroidectomy. The relationship between thyroid carcinoma and Hashimoto's thyroiditis continues to be a controversial subject. This relationship is discussed including the epidemiological and therapeutic implications of the coexistence of these two pathologies.
