Primary lymphoma of the uterine corpus (PLUC) is an extremely rare neoplasm. We report a case of PLUC in a 78-year-old woman with vaginal bleeding without hepatosplenomegaly, adenopathies, or bone marrow infiltration, classified as stage I. A diagnosis of diffuse large B-cell lymphoma was made in endometrial curettage tissue. Immunohistochemical study(More)

Lymphocytic hypophysitis should be included in the differential diagnosis of hypopituitarism at any age. The association with idiopathic retroperitoneal fibrosis suggest an autoimmune origin for this(More)
