Clinical and endocrine aspects of pituitary tumors

ABSTRACT

To study the clinical spectrum and endocrine profile of pituitary tumors presenting to a tertiary care endocrine center. Retrospective analysis of clinical and hormonal data of patients with pituitary tumors admitted in the Endocrinology Department of Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir India between January 1989 and December 1998. Over a period of one decade, 75 subjects were diagnosed to have pituitary tumors. Somatotroph adenoma was the most common pituitary mass lesion seen [44/75] and followed in the decreasing order of frequency, by non-functioning pituitary tumor [12/75], prolactinoma [11/75] and corticotroph adenoma [8/75]. Overall there was a male preponderance [male to female ratio was 4134]. Subjects with somatotroph adenoma presented with classical features of acromegaly mean fasting and post glucose suppression growth hormone levels were 34.04 +/- 11.67 and 36.47 +/- 6.64 ng/ml. Eleven subjects [9 females and 2 males] had prolactinoma; females presented with the classical symptom complex of amenorrhea-galactorrhea while males presented with headache, visual disturbances and impotence. The 12 subjects with nonfunctioning pituitary tumors presented with features of mass lesion. Of the 8 subjects [6 females and 2 males] with corticotroph adenomas, 2 were confirmed to have periodic hormonogenesis. In an endocrine center, functioning pituitary tumors are more often seen than non-functioning tumors
