REPORT ON RARE TUMORS AND TUMOR-LIKE CONDITIONS OF THE PITUITARY (WITH A 10-YEAR REVIEW)

The objective of this work was to analyse 10 years of experience of the Clinical Department of Pathology &#8220 ; Ljudevit Jurak&#8221 ; in pituitary expansive neoplastic processes diagnostics. Our special attention was paid to rare pituitary tumours. Various types of pituitary tumours were evaluated according to age and sex, with exception of pituitary adenoma. Study was designed as a retrospective review of the records of patients who underwent surgery of pituitary tumours between January 1989 and February 1999. The distribution of tumours was analysed according to age at surgery, sex, size and patohistological type of the tumour. Total of 238 pituitary tumours was diagnosed during the last 10 years. The most common conditions were Adenoma glandulae hypophiseos (95, 8%). Rare conditions were diagnosed in 10 cases (4, 2%). Average age at diagnosis was 43, 4 years. Male to female ratio was 1:1. Average age of patients with rare pituitary tumours was 45, 52 years, with male to female ratio of 1:1, 3. In comparison with more common pituitary expansive processes it can be concluded that rare conditions emerge at any age and regardless to sex . Until now only few studies have attempted such an analysis as the one presented here. Most of the published data suggested that frequency of different types of pituitary tumours vary according to age and sex. Our report confirms those observations with addition of possibility of diagnosing rare and unexpected conditions and tumours among any age group in both genders.
