Cells with cytologic and immunohistochemical features of Leydig cells are normally present in the ovary and the ovarian hilum, are testosterone-producing, and have been referred to as ovarian hilus cells. Rarely these cells form nests or nodules in extraovarian sites such as the mesovarium or mesosalpinx. Because they are so rare, these nodules can present a diagnostic challenge when first encountered. This report describes 2 such incidental nodules in the mesosalpinx associated with a small paratubal cyst and suggests that the term Leydig cell nodule be preferred over the nonspecific and confusing historical term ovarian hilus cell nest.
