ABSTRACT
A 46-year-old man presented with an unusual angiosarcoma of skin and urinary bladder, clinically suggestive of Kaposi's sarcoma (KS). Histologically, the pattern was that of an anaplastic angiosarcoma with only minimal regions considered characteristic of KS. It is suggested that this rare type of angiosarcoma may be closely related to, if not best classified as, an anaplastic variant of KS. The cutaneous lesions responded to intralesional vinblastine. The association of anaplastic angiosarcoma with homosexual sexual practices should be investigated along with those cases having the classical histologic characteristics of Kaposi's sarcoma.

A new articulated teaching attachment with a single joint is described. The attachment allows a 360-degree rotation in 3 planes (sagittal, horizontal and frontal) by the 3 rotary unions at the single joint with only 2 tubes. Simultaneous observation by 2 persons and the operator is achieved by combining 2 of these optical units. The attachment may be sterilized by soaking. It can be dismantled for cleaning and for replacement of any damaged parts. Finally, it facilitates taking still photographs, movies and television endoscopy without interference to the operator.
