anonymous Right OVARY, cyst : Cystic adult granulosa cell tumour. 100%. Important differential diagnosis includes sex cord tumour with annular tubules (SCTAT). More blocks may be taken to look for more characteristic areas of SCTAT. The cores and the basement membrane-like material in SCTAT are PAS-positive. One-third of cases of SCTAT are associated with Peutz-Jeghers syndrome.  90
