A case report of robot-assisted laparoscopic left renal mucinous cystadenocarcinoma radical nephrectomy and review of literature

Abstract

Background: Mucinous cystadenocarcinoma (MC) of the kidney is a rare renal epithelial tumor originating from the renal pelvic urothelium. There are only a few published reports on MC. Due to its rare and unknown tissue origin, its diagnosis is difficult which almost can be diagnosed through the pathological method.Case presentation: In this case report, we report a female patient whose chief complaint was low back pain lasting for one month. The three-dimensional computed tomography scan of the urinary system detected approximately 7 cm of a left renal cystic mass. The renal cystic mass was diagnosed as MC after robot-assisted laparoscopic radical nephrectomy. The MC originated from the kidney after completing colorectal adenocarcinoma and ovarian adenocarcinoma.Conclusions: We reported a case of MC of the kidney which was a rare renal tumor. We not only aimed to present an unusual case of MC and review the previous literature on its pathology and differential diagnosis, but also used new method to treat this type of tumor.

A Very Rare Case of Metastases to the Nasal Cavity from Primary Rectal Adenocarcinoma

“…Both the CK7-/CK20 + phenotype and CDX2 antibody expression are highly specific and sensitive markers of the origin of colorectal cancer, and the specificity of CK7-/CK20 + is 97.6%. [5] In our case, expression of CK20 and CDX2 with no expression of CK7, though does not rule out a primary tumour completely, but does strongly point towards metastasis from the colorectal carcinoma. This is a good example that even with all state-of-the-art diagnostic facilities available, it is impossible to call the tumour in the nasal cavity a primary or secondary with 100 per cent certainty.…”
