The histologic diagnosis was based on the presence of signet ring

The histologic diagnosis was based on the presence of signet ring cells filled with cytoplasmic mucus-containing vacuoles compressing and displacing the nucleus into a peripheral crescent alongside the cell wall. The component signet ring cells are variable; it is >75% in almost half the cases.5 Our first case was an invasive tumor, which extended to the perivesical fat. Indeed, the insidious progression

of this entity explains the local character already advanced at diagnosis. At the time of diagnosis, about 25% of patients have distant metastases and approximately 50% have stage IV disease.6 Primary signet ring cell carcinoma of the urinary bladder has an ominous prognosis as it is diagnosed at an advanced stage. The treatment is surgical and consists of an early radical cystectomy. Resection is often incomplete with

no clear margins on the specimen.7 Considering the rarity of this histologic type of tumor, there is no consensus regarding the management after HKI 272 surgical care. Chemotherapy and radiation therapy are discussed. Adjuvant chemotherapy with 5-fluorouracil associated with adriablastin or bleomycin seems to give favorable responses, by analogy with stomach plastic linitis.8 Our second patient had no palliative chemotherapy because of altered general condition. The primary SRCC of the urinary bladder is a rare and aggressive tumor; the histologic I-BET151 purchase type justifies a surgical strategy associated with a multidisciplinary approach. Prognosis is poor although some patients may benefit from surgical resection. Adjuvant chemotherapy should be discussed even if consensual attitude has not been defined. “
“A rare variant of lipoma, angiomyxolipoma (vascular myxolipoma) was first reported by Mai et al1 in 1996. The tumor was composed of an admixture of myxoid stroma, mature adipose tissue, and vascular crotamiton channels. Since then, an additional 17 cases have been reported across a broad age range and in different locations. We report the first case in English medical literature of renal angiomyxolipoma in an adult male. Among adult soft-tissue tumors, adipose tissue tumors are by far the most common.

Although ordinary subcutaneous lipomas do not represent a major diagnostic problem, the remaining benign tumors and tumor-like lesions of adipose tissue can be more challenging, especially if occurring at unusual locations and/or containing other tissue elements.2 and 3 Our case will be the 18th reported case of angiomyxolipoma and the first of renal origin. A review of the literature along with a discussion of diagnosis and follow-up are illustrated in the report. We report a 43-year-old man who presented to our urology clinic with left flank pain of 1-year duration. On investigation, he was discovered to have bilateral kidney masses and splenomegaly after a computed tomography (CT) scan (Fig. 1). Radiologic findings were highly suspicious for lymphoma in the presence of splenomegaly and distal ileal wall thickening.
