A case of hydrocolpos.

Hydrocolpos has received little attention during the past decade (Dewhurst, 1963; Cook and Marshall, 1964). Consequently many doctors are not aware of this retention cyst of the vagina and when seen it is often misdiagnosed. On the other hand the related disorder of haematocolpos usually found at puberty is well known and more often suspected than confinned. Cook and Marshall (1964) recalled that of the 49 cases of hydrocolpos in infants under 10 months recorded up to date of their study only 26 were diagnosed before treatment. The case mortality was 35%. Of the 16 patients who underwent laparotomy when undiagnosed, eight had a hysterectomy because malignant disease was suspected. In view of these startling figures a further case of hydrocolpos is reported.
