All patients
were female and radical surgical procedure, total excision or resection was performed four times,
and partial excision once. In all patients the postoperative course was uneventful and they are all
alive and well. Examined by conventional histological and special immuno-histochemical stains
the tumors fulfilled diagnostic criteria for these rare cystic growths. The cyst wall was composed
