FACCIN12 From the Departments of Morbid Anatomy of University College Hospital Medical School, London and the Royal Cornwall Hospital (Treliske), Truro, Cornwall, UK SUMMARY Two further cases of 'female adnexal tumour of probable Wolffian origin' are described Both were retroperitoneal and presented a unique histology of uniformly close-packed gland spaces. solid islands, cords, and diffuse areas. A small hamartoma in a female fetus, part of which resembled the tumours, was traced to an area of near apposition with some paroophoron canals, providing further evidence of a Wolffian origin. The literature of this and some other putative Wolffian tumours is briefly reviewed, and the relation to rete adenomas is discussed. True tumours of the broad ligament are uncommon fibroids and a grapefruit-sized tumour extending and many of them resemble primary tumours of the from the lateral pole of the right ovary between the ovary and uterus (Gardner et al., 1957).
