Primary Retroperitoneal Mucinous Cystadenocarcioma Involving the Splenic Hilum

Primary retroperitoneal mucinous cystadenocarcinoma is a rare tumor, and it is similar to its ovarian counterpart, but it is without any evidence of ovarian, pancreatic or any other extra-retroperitoneal origin. The histogenesis of this neoplasm remains uncertain. Mucinous or colemic metaplasia of the retroperitoneal mesothelium has recently been proposed as its origin. A 39-year-old woman was diagnosed with a 13-cm cystic lesion in the left retroperitoneum; this was mucinous cystadenocarcinoma and no primary tumor was identified. We report here on a primary retroperitoneal mucinous cystadenocarcinoma that involved the splenic hilum, and we include a review of literature.

Splenic Lymphangioma of the Spleen in an Elderly Patient

A splenic cystic lymphangioma is a very rare benign condition, and is classified as one of the cystic proliferations of the spleen. They are considered to result from developmental malformation of the lymphatic system and can be divided roughly into two types according to the extent of the disease: the isolated type, where only the spleen is involved, and the widespread type, where splenic involvement is an expression of multiple organ involvement. Thery are usually seen in children and often found incidentally. Herein, a case of cystic lymphangioma of the spleen in an elderly woman is presented, with emphasis on the rarity of cases in old age and on the problems of differential diagnosis in relation to other cystic proliferations of the spleen.
