ABSTRACT
We present two autopsy cases of refractory ascites/hydrothorax associated with systemic deposition of low-molecular weight dextran that had been used in hemodialysis over an extended period. The most striking autopsy findings in both cases were dense accumulation of dextran-laden macrophages in sinusoids of reticuloendothelial organs. These accumulated macrophages seemed to have disturbed blood and lymph flow. Based on these findings, we concluded that the persistent ascites and hydrothorax were attributable to systemic deposition of dextran, especially the accumulation of dextran-laden macrophages in the reticuloendothelial organs. We suggest that dextran solution should immediately be designated as contraindicated for hemodialysis patients.

Differentiation of endocervical adenocarcinomas involving the uterine corpus from primary endometrial (EM) carcinomas involving the cervix is, not only clinically but also pathologically, often difficult. We report a case of gastric-type endocervical adenocarcinoma involving the corpus that could be correctly diagnosed because it was a unique endocervical adenocarcinoma subtype. A 69-year-old woman who presented with abnormal genital bleeding was diagnosed as having a uterine adenocarcinoma on pathological examination of EM biopsy. Preoperative imaging findings and a surgical specimen showed that the tumor was mainly located in the corpus and involved the cervix. We considered at first that the tumor was an EM adenocarcinoma invading into the cervix. However, results of an immunohistochemical examination indicated that it was a gastric-type mucinous adenocarcinoma derived from the endocervix. Our final pathological diagnosis was a gastric-type endocervical adenocarcinoma spreading to the uterine corpus.
