Introduction:

the term pituitary tumor groups a series of miscellaneous diseases and corresponds to primary tumor lesions of the pituitary parenchyma.

Objective:

to characterize patients with pituitary tumors seen at the "Hermanos Ameijeiras" Clinical Surgical Hospital between 2017 and 2019.

Methods:

observational, descriptive, longitudinal and prospective study of patients with a diagnosis of pituitary tumors seen in the outpatient clinic of Pituitary Diseases and the Endocrinology Service of the Clinical Surgical Hospital "Hermanos Ameijeiras" between 2017 and 2019. The sample consisted of 267 patients. The individual medical records of the patients were used for data collection. Descriptive statistics were used.

Results:

female sex predominated (79,03 %) and patients with non-functioning pituitary tumor (59,93 %), followed by those with prolactin-secreting tumors (31,46 %). Only in one patient with non-functioning pituitary tumor the finding was incidental. The most common symptom expressed by the patients was headache (85,77 %). In each functioning tumor an excess production of the specific hormone was determined. A predominance of patients with microadenomas was found (70,79 %).

Conclusions:

Pituitary tumors were common in female patients, with predominance of the non-functioning type and microadenomas. Although the diagnosis may be incidental, many patients present with mass effect symptoms such as headache. Patients present with increased tumor-specific hormones.
