Pituitary adenomas (PAs) are abnormal benign tumors that develop in the pituitary gland. This study aimed to assess the prevalence of different types of PAs with an indication for trans-sphenoidal surgery in a well-defined population referred to Loghman Hakim Hospital during 2001-2013. In this retrospective study, the prevalence rate and symptoms associated with pituitary mass and hormone excess in operated patients were investigated. The diagnosis was verified after retrieval of clinical, hormonal, radiological, and pathological data. Demographic data were collected in all cases. Descriptive analysis, t-test, one-way analysis of variance and Fischer exacts test were used. A total of 278 patients with PAs who underwent surgical interventions were evaluated. Most of the patients were aged 40-50 years with an average of 41 ± 14. The most prominent complaint was pressure effect, which was detected in 153 cases (55.2%). At the second place, hormonal disorders were observed in 125 cases (44.8%). Type of pituitary tumors were: Prolactinomas (29.1%), growth hormone (GH)-producing tumors (25%), nonfunctioning PAs (28.4%), adrenocorticotropic hormone (ACTH)-producing tumors (2.1%), thyroid stimulating hormone (TSH)-producing tumors (0.7%), GH/prolactin (13.6%), GH/ACTH (0.3%), and TSH/ACTH (0.3%). Fifty-seven patients presented with recurrent adenomas. Pituitary apoplexy was found in 11 patients. One case of Sheehan syndrome was recorded among these. The correlations between clinical symptoms and patients, age and sex were not significant. The overview of demographic characteristics in Iranian patients with PAs with surgical indication has been discussed in the present investigation. The prevalence of different types of PAs and the most common clinical symptoms have been demonstrated.
