Abstract: The presence of salivary gland tissue in the sella turcica has rarely been reported, mainly after pituitary examination at autopsy. Only
five symptomatic cases have previously been described, mainly associated with Rathke’s cleft cyst. We report a 17-year-old boy presenting with
headaches and hyperprolactinemia. The MRI showed a 19 mm sellar mass that at surgery revealed as a cystic lesion filled with mucinous
fluid. The histological examination documented the presence of ectopic salivary gland tissue in the wall of a Rathke’s cleft cyst. The present
report focuses on the possible pitfalls when dealing with unusual sellar lesions, and the need of increased awareness of this rare condition.
Keywords: Salivary gland tissue, pituitary, Rathke’s cleft cyst
