INTRODUCTION: Cystic sellar salivary gland-like lesions (CSSLs) are exceedingly rare, with fewer than a dozen case reports. They contain amorphous colloid identical to Rathke cleft cyst contents, but the cyst wall additionally shows cohesive aggregates of benign salivary glands. We report three new examples. MATERIALS AND METHODS: Two cases were seen at University of Colorado Denver and one at Memorial Sloan Kettering (MSK). Molecular testing was attempted on two of three. RESULTS: Case 1 is a 20-year-old female who presented with panhypopituitarism and was found to have a suprasellar mass that proved to be a CSSL. She received no postoperative adjuvant therapy, but recurrence of headaches and blurred vision 2 years later prompted return to medical attention. A much smaller local cyst recurrence was now accompanied by a thickened, bulbous infundibular stalk. Second resection yielded a gliotic infundibular stalk and amorphous mucin, but no residual salivary-like glands. She is without further recurrence on 6-year follow-up. Case 2 is a 29-year-old female with headache; while seen initially at a tertiary care center, diagnosis was only made after consultation at MSK. Case 3 is 68-year-old female who had originally presented with apoplexy to an outside hospital 7 years prior to surgery and diagnosis. Molecular testing was uninformative on case 1 and negative for mutations or fusions on case 3. CONCLUSION: Few pathologists or neuropathologists have encountered CSSLs in their practices; case 1 produced recurrence and significant infundibular stalk damage, and case 3 originally manifested apoplexy, features not previously reported.
