The concomitant presence of three histopathologically different entities in the pituitary gland is a rare occurrence. Most publications identify at least two distinct pathologies, mainly, a pituitary adenoma coexisting with a second intrasellar lesion. We present a case of a 71-year-old female referred for evaluation and treatment of acromegaly. Questioning revealed she was experiencing facial palsy, visual disturbances, and syncopal spells for several weeks. When laboratory evaluation showed elevated somatomedin (IGF-I) levels and an oral glucose tolerance test failed to demonstrate any suppression of her growth hormone (GH) values, an MRI of the pituitary revealed a sellar mass. A presumptive diagnosis of pituitary adenoma was established. The patient underwent transsphenoidal resection of the sellar mass, which proved to be a large B-cell lymphoma (Stage I-E) associated with areas of adenoma and lymphocytic hypophysitis.

Acromegaly is always complicated with comorbidities and increased mortality. The disease activity and mortality outcomes are highly correlated to the level of growth hormone and insulin-like growth factor 1. A variety of clinical manifestations of acromegaly have been reported. We present a unique case where a 49-year-old male was diagnosed with acromegaly with a first manifestation as an episode of diabetic ketoacidosis. Because he refused any suggestion of treatment, a recurrent episode of diabetic ketoacidosis with pituitary apoplexy occurred. A huge B-cell lymphoma displaying as a huge facial mass followed within 1 year of the diagnosis of acromegaly. Death from advanced cancer ensued 3 years later. This clinical experience strongly reinforces the urgency of controlling growth hormone and insulin-like growth factor 1 as soon as possible once acromegaly is diagnosed.
