The case of a patient with a massive intraventricular hemorrhage arising from a pituitary chromophobe adenoma is described. This rare and disastrous complication was ascribed to the large suprasellar extension of the tumor and its close proximity to the floor of the third ventricle. Hemorrhage in the tumor extended along the path of least resistance and ruptured into the third ventricle. A partially treated hyperviscosity syndrome and chemotherapy for an unrelated malignancy (multiple myeloma) may have predisposed the patient to the necrosis and hemorrhage in the pituitary tumor.

To explore the expression of pituitary tumor-transforming gene (PTTG) in elderly patients with multiple myeloma (MM) and its relationship with MM, the expressions of PTTG mRNA were detected in bone marrow mononuclear cells (BMMNC) from 33 patients with MM and 10 normal controls by using reverse transcriptase-polymerase chain reaction (RT-PCR). The results showed that the expression of PTTG mRNA in MM patients (0.3415 +/- 0.2172) was significantly higher than that in normal controls (0.0590 +/- 0.0233) (P < 0.05). It is concluded that the overexpression of oncogene PTTG may be related to genesis and progression of MM. It provided a new ideas to study the pathogenesis and gene therapy for MM patients.

The study was purposed to explore the expressions of pituitary tumor transforming gene and c-myc gene in patients with multiple myeloma (MM) and its relationship with pathogenesis of MM. Expressions of pituitary tumor transforming gene and c-myc gene mRNA in BMMNC from 33 patients with MM and 10 normal controls were detected by reverse transcriptase-polymerase chain reaction (RT-PCR). The results showed that the expressions of pituitary tumor transforming gene and c-myc gene mRNA were significantly higher in MM patients those that in normal controls (p<0.05). The expression of pituitary tumor transforming gene mRNA was significantly correlated with the expression of c-myc gene (r=0.801, p<0.05). In conclusion, the overexpressions of pituitary tumor transforming gene and c-myc gene may be related to the pathogenesis and progression of MM.

A case of multiple myeloma presenting as a plasmacytoma and mimicking a pituitary tumor is reported. The importance of recognizing the existence of plasmacytoma in the differential diagnosis of sellar and parasellar tumors is stressed, as it leads to important differences in management. The literature is reviewed. Patients presenting with plasmacytoma with symptoms of a pituitary adenoma have an average age of 58 years; the male to female ratio is 3:1; diplopia, headache, and progressive visual loss are the most important symptoms; third, sixth, and fourth cranial nerve palsies are the most common signs; and pituitary function is usually normal. CT scan of the sellar region is the imaging modality of choice; pathologically, light and electron microscopy are invaluable in making the correct diagnosis. Making the correct diagnosis allows further appropriate investigation for systemic disease and consequent management.

Intrasellar plasmacytoma is a rare pituitary tumor, which originates from monoclonal plasma cells in a single lesion. Knowledge of its features comes from case reports only. Here, we present an interesting case of a 77-year-old woman with a presumptive diagnosis of non-functioning pituitary adenoma, as based on both clinical and radiological examinations. Following endoscopic endonasal transsphenoidal surgery, the definitive diagnosis of intrasellar plasmacytoma was made by immunohistochemical analysis of the sellar mass. Intrasellar plasmacytoma is rare, but it should be evaluated in the differential diagnosis of a pituitary mass due to its different therapeutic approach and prognosis, since it can frequently progress to multiple myeloma.
