The rate of extracapsular extension was found to be directly proportional to the number of axillary lymph nodes involved and the stage of disease. Extracapsular extension had significant prognostic value in both univariate and multivariate analysis for DFS and DMFS but not OS. The reason for ECE not affecting OS might be related to the much more dominant prognostic effect of the involvement of four or more axillary nodes on OS. Studies with more patients are needed to demonstrate that ECE is a likely independent prognostic factor for OS.

We report the rare case of a 43-year-old woman with a simultaneous meningioma of the sphenoid wing and an amyloid-containing prolactinoma. The patient, who presented with a 17-year history of amenorrhea, and galactorrhea, was found to have a 10-mm mass in the pituitary gland. During excision of this lesion, another mass was noticed, which was located in the sphenoid wing. Both lesions were completely excised. Histopathological examination revealed that the pituitary tumor was a prolactinoma with diffuse amyloid deposition and that the second tumor was a typical meningioma. The coexistence of a prolactinoma containing amyloid and a meningioma is very rare in the literature, so this case is presented here with its histochemical and immunohistochemical features. We discuss the significance of prolactinoma containing amyloid and the simultaneous presentation of these two tumors.
