Adenoid cystic carcinoma of the thymus gland: a rare tumor.

Thymic carcinomas are rare malignant neoplasms. We present a case of adenoid cystic carcinoma of thymus in a 65-year-old woman that was initially misdiagnosed and was treated as non-small cell carcinoma of the lung. We describe the clinical and pathologic features of this extremely rare thymic epithelial tumor, with survival at 2 years and 6 months of follow-up.
