UNASSIGNED: A 90-year-old @entity1 was referred to our hospital because of abdominal distension and pretibial @entity4 . No @entity5 were palpable in either breast. Her abdomen was distended and palpitation was noticed. Laboratory examination revealed @entity2741 and elevated levels of @entity5 markers(PIVKA- II , CEA, CA19-9, SCC). Contrast-enhanced computed tomography(CT) showed @entity1143 and @entity843 , an approximately 17-mm high-contrast mass in the D area of the left breast, and osteolysis of the dorsal lumber spine. We initiated treatment for @entity1143 , @entity843 , and @entity2741 . However, on her 11th day in the hospital, hematemesis was observed and the @entity1 died. We suspected @entity3 of a @entity5 , but a @entity75 had not been identified; therefore, an autopsy was performed. Autopsy showed a 17-mm mass in the D area of the left breast. Histopathological examination showed the growth of a signet-ring cell @entity5 that was immunohistochemically ER-positive, @entity7273 -positive, and @entity5962 -negative. The @entity1 was diagnosed with primary @entity0 derived from @entity1137 . We reported a rare case of primary @entity0 with a review of literature.
