Beta-2 microglobulin amyloidosis presenting as bilateral ovarian masses: a case report and review of the literature.
We report a case of systemic beta-2 microglobulin amyloidosis (B2M) in which the initial clinical presentation was that of bilateral ovarian masses. A 56-year-old woman who had been on renal dialysis for 12 years because of familial glomerulonephritis underwent a total hysterectomy and bilateral salpingo-oophorectomy for suspected ovarian malignancy. Pathologic findings included extensive amyloid infiltration of both ovaries, fallopian tubes, and focal perivascular deposition in the myometrium. The diagnosis of amyloidosis was confirmed with Congo red stain, B2M immunohistochemistry, and electron microscopy. Systemic amyloidosis in renal dialysis patients commonly presents as bone and/or joint disease, although visceral involvement has been reported. This is the first report in the English language literature to describe amyloidosis presenting as bilateral ovarian masses.
