[Cystosarcoma phyllodes of the lacteal glands].

Thirty-three cases of phyllode cystosarcoma were diagnosed in the course of 21 years at the Tumour Department of the Berlin School of Medicine (Charité). Ten of them were found to be in sarcomatous degeneration. Metastasation was positively established in four of these ten cases, and locally delimited recurrences were recorded from two. Metastasation in cases of phyllode cystosarcoma has been found to occur rarely through regional lymph nodes. Therefore, routine removal of those lymph nodes is not considered necessary.
