Nontrophoblastic pathology of the female genital tract and peritoneum associated with pregnancy.

This report reviews the clinical and pathological features of nontrophoblastic lesions that involve the female genital tract and peritoneum and are typically or exclusively associated with pregnancy or the puerperium. The majority of them are nonneoplastic lesions that may be confused with a neoplasm on clinical or pathological examination. Pregnancy-related changes within gynecological tumors that may create problems in histological interpretation also are discussed briefly.
