“…Primary cystadenocarcinoma of the spleen is extremely rare. All the reported cases were mucinous type [2], [4], [5], [6], [7], [8], [9]. The hypothesized origins of these tumors include (1) ectopic pancreatic tissue; (2) ectopic intestinal tissue; and (3) invaginated mesothelium of the splenic capsule [2], [6].…”

The commonly seen primary malignant neoplasms of the spleen are angiosarcoma and lymphoma. We present a case of serous cystadenocarcinoma of the spleen. It was presumed to be originated from dropped nonmalignant ovarian tissue, which was accidentally implanted to the splenic surface during hysterectomy and bilateral salpingooophorectomies for torsion of right fallopian tube 9 and half years ago and transformed into serous cystadenocarcinoma later. Computed tomography demonstrated a multilocular predominantly cystic tumor with internal soft tissue components in the spleen.

“…The exact histogenetic mechanism of splenic mucinous cystic tumors is unknown except those arising from heterotopic pancreatic tissues [1]. However, mucinous cysts are usually found in association with the cystadenoma of pancreas, pseudomyxoma peritonei and mucocele of appendix [7]. Only few cases, in which the tissue of origin was un-defined, are documented in the literature [3-7].…”

A Rare Case of Primary Mucinous Cystadenoma of Spleen

Mucinous cystadenomas are relatively uncommon benign cystic tumors. Most of them are found in the ovary, pancreas, and appendix. Primary mucinous cystadenoma of spleen is extremely rare and only countable cases have been recorded. These are assumed to arise from heterotopic pancreatic tissue or invaginated spleenic capsular mesothelium. We present a rare case of primary mucinous cystadenoma of spleen without pancreatic tissue in it. Exact tissue of origin could not be determined.KeywordsCystadenoma; Splenic cyst; Pseudomyxoma peritonei

A case of splenic low-grade mucinous cystadenocarcinoma resulting in pseudomyxoma peritonei

et al. 2010

Primary splenic mucinous cystadenocarcinoma (MCCa) is extremely rare, and only six cases appear to have been reported previously. We present herein a case of primary splenic MCCa resulting in pseudomyxoma peritonei (PMP). A 66-year-old Japanese woman presented to a hospital with a chief complaint of upper abdominal pain and a 7-year history of splenic cyst. Cyst rupture was noted on computed tomography, and splenectomy was performed. The abdominal cavity was filled with a large amount of gelatinous ascites, with the appearance of PMP. On the cut surface, multiple cysts containing mucinous material were found within and outside the spleen. Microscopically, splenic parenchyma was occupied by large mucinous pools focally lined with mucinous epithelial cells and mesothelial cell-like cells, which were considered benign. Outside the spleen, a low-grade MCCa component was found. No ectopic pancreatic or intestinal tissue was identified. Although most PMP cases are known to be caused by low-grade mucinous appendiceal tumor, the present case represents the first report of a splenic MCCa resulting in PMP.
