A case of large sized angiomyolipoma with atypical clinical presentation is reported. The retroperitoneal mass, showed by ultrasonography, was mainly made by fat tissue, as showed by CT and MRI, and it was associated with focal, probably metastatic, liver lesions. The diagnostic hypothesis of retroperitoneal liposarcoma with liver metastases was made. In the same time a colon neoplasm was found and US-guided biopsies of both the liver lesions and the retroperitoneal mass were carried out. The former were found to be metastases from colon cancer while the latter was a renal angiomyolipoma. The reported case underlines that renal angiomyolipoma if large sized and with atypical clinical presentation may be difficult to differentiate from retroperitoneal, even malignant masses. The hystological evaluation by means of needle biopsy or surgical resection becomes therefore mandatory.

A preoperative inferior vena cava (IVC) filter is reported to be effective in surgical cases with proximal deep venous thrombosis (DVT) or in which pulmonary embolism (PE) has already developed, and considered to be at high risk of developing secondary fatal PE during or after surgery. However, guidelines for using an IVC filter have yet to be established. The patient in the present report had two huge tumors, ascending colon cancer and renal angiomyolipoma, which occupied the entire right half of the abdomen, coexisting PE, DVT and tumor thrombus in the right renal vein. Secondary PE is fatal in the perioperative period, therefore, the vena cava filters were preoperatively inserted into the supra- and the infrarenal IVC. We successfully removed the tumors without complications. The patient is alive without tumor recurrence and PE or recurrent DVT 1 year and 6 months after surgery. The coexistence of two huge abdominal tumors as potential causes of PE and DVT is extremely rare, and we could have safely undergone the operation, using two vena cava filters in the supra- and infrarenal IVC.

We describe how we resected a hepatic angiomyolipoma and ascending colon cancer synchronously via laparoscopic left lateral segmentectomy and laparoscopic right colectomy, respectively. The patient was a 72-year-old man, admitted to our hospital after a liver tumor and ascending colon cancer were detected during a general health check. Computed tomography (CT) showed a hypervascular liver tumor mimicking hepatocellular carcinoma, 2 cm in diameter, in segment 3 of the liver. The ascending colon cancer was diagnosed as T2N0M0, Stage I. The left lateral liver and right colon were mobilized laparoscopically and hepatic transaction, followed by resection and anastomosis of the colon, were performed extracorporeally through the same 7-cm upper median incision. This type of laparoscopy-assisted combined resection is useful to obtain a pathological diagnosis of the liver tumor and to remove the entire tumor in a minimally invasive and cosmetic manner.

While the presence of multiple primary malignancies in the same patient is a well described phenomenon, there is no clear association between various histological subtypes of renal cell carcinoma (RCC) and the synchronous presence of colon malignancies. We present the rare case of an 81-year-old female patient suffering from chromophobe renal cell carcinoma (chRCC) and an angiomyolipoma of her left kidney, synchronous with an adenocarcinoma of the caecum. While there is an established connection between RCC and colon cancer, a literature review is performed to specify this association in regard to chRCC and the synchronous presence of colon malignancies.
