[Sarcomatoid carcinoma of the bladder in a 25-year-old man].

A 25-year-old patient with a rapidly growing sarcomatoid carcinoma of the urinary bladder is reported. The diagnosis was made on the basis of extended atypical proliferations of spindle or pleomorphic cells in the area of pelvic floor and the radix of the penis. The tumor showed invasion of the blood and a high Ki-67 growth fraction up to 40%. Immunohistochemically, the reactions with antibodies against cytokeratin, EMA, and vimentin were positive, while negative results were obtained in reactions with antibodies against desmin, actin, PSA, S 100, human epithelial antigen (Ber-EP4), and cytokeratin 13. The differential diagnosis against myosarcomas, pseudosarcomatous lesions, and inflammatory pseudotumours is discussed. After radical surgery a pelvic recurrence and pulmonary metastases developed, which led to the patient's death 3 months later. This case shows that sarcomatoid carcinomas of the urinary bladder can be found even in young people.

Arsenate ion reduction in non-living biological materials.

The reduction of arsenate ion to arsenite ion by a variety of tissues was widely distributed, and not a property of any particular tissue. The nature of the reduction was investigated by using various chemical inducers and inhibitors and is believed to be chemical in nature.

The determination of arsenite and arsenate ions in fish and shellfish by selective extraction and polarography.

Arsenite ion, as arsenic trichloride was extracted into benzene from strongly acidified tissue homogenates. Following this, arsenite was extracted from the benzene into water, made up in 1N HCl and analyzed polarographically. Arsenate ion, left in the homogenate after arsenite extraction is isolated in exactly the same way following treatment of the homogenate with cuprous ion to reduce arsenate to arsenite ion. Treatment of the acidified homogenate with cuprous ion prior to extraction gives a homogenate which is readily analyzed for total "inorganic" arsenic. The method was efficient to a maximum level of about 20 mug inorganic arsenic since at higher levels lower recoveries were found. Analysis of a variety of marine biological specimens, with levels of total arsenic up to 40.5 ppm, indicated little of this arsenic was present in an inorganic form. Post mortem reduction of arsenate to arsenite was found to occur rapidly in fish tissue.
