[Coexistence of a partial hydatiform mole and a viable twin pregnancy. A case seen at the Sokode regional hospital (Togo)].

A case was seen of partial hydatidiform mole coexisting with a viable twin pregnancy. Apart from prematurity which created early problems in caring for these girls twins, born with a good Apgar score and birth weights of 1400 g and 1350 g, the outcome was satisfactory for both the mother and daughters, who thrived marvelously. The incidence of this clinical form of trophoblastic disease which is 1/10,000 deliveries in our series confirms it rarity as reported by many authors.
