INTRODUCTION: Epidermoid cysts (EC) are lesions developing from neuroectodermal epithelial cells. They represent 1-2% of all intracranial tumors and are usually found in cerebellopontine angle and parasellar regions. To the best of our knowledge, only 27 cases have been reported of EC in sellar and suprasellar region. In 12 cases out of the 27, surgery was done by craniotomy means. The 7 most recent manuscripts (with 15 patients described) share in common the use of endoscopic endonasal approach (EEA) to perform surgical removal. RESULTS: In this paper, we report the safe removal of epidermoid cysts arising from the pituitary using an EEA in two patients, which should be the sixth such description in literature. In both cases, resection and evolution was favourable. DISCUSSION: Surgical resection is the treatment standard for epidermoid cysts, with total resection including the cyst wall to prevent recurrence when possible. The degree of resection obtained is limited by adherence to nearby neural and vascular structures. The advent of EEA approaches has allowed safe maximal resection especially in midline lesions nearby sellar and suprasellar compartiments.
