Berry Hart performed ovariotomy on a woman in the fifth month of pregnancy, and removed a dermoid of the left ovary ‘enlarged to about the size of a man’s brain by recent hæmorrhage due to the twisting of a pedicle’. The patient died on the ninth day. A frozen section was made of the pelvis, and on inspecting the cut surface the right ovary, converted into a dermoid, was found incarcerated by the gravid uterus. Many cases have been published in which ovariotomy has been undertaken during the late months of pregnancy, or shortly after delivery, and the surgeons have been astonished to find both ovaries converted into tumours; in very many instances they were dermoids. Cases of this kind have been recorded by Knowsley Thornton, F. Page, Cullingworth, Berry Hart, Malcolm Campbell, and others, including myself. These observations demonstrate that a woman may have both her ovaries occupied by dermoids, yet the glands are capable of yielding fertilizable ova. Campbell relates that Brewis, in performing an ovariotomy during pregnancy, attempted to conserve some ovarian tissue by resecting the dermoids; this proved impracticable, and both ovaries were excised. Miss Ivens records a case in which a woman thirty-five years of age was five months pregnant and required ovariotomy on account of an incarcerated ovarian dermoid. In the course of the operation both ovaries were found to contain dermoids. A tumour was successfully excised from each. Pregnancy continued undisturbed. REFERENCES CAMPBELL, M.
