Abstract
Both of Pituitary adenoma (PA) and Rathke cleft cyst (RCC) are the most common and benign sellar lesions. Generally, the origin of RCC is considered to be derived from remnants of Rathke punch, while PA is formed by proliferation of the anterior wall of Rathke pouch. Although they have a possibility to share a common embryological origin, the coexistence of PA and RCC is extremely rare. Here, the authors report a 50-year-old male patient who was found to have a large cystic sellar lesion, and surgical resection revealed components of a RCC coexisting with a PA. This collision reminded us of the possibility of RCC coexisting with PA. Furthermore, a clinicopathologic relation of them were reviewed and investigated.
