Abdominal wall implantation of an endocervical-like mucinous borderline tumor.

Abstract

We present the case of a 21-year-old woman in whom development of a bulky abdominal wall metastasis in a laparotomy scar led to discovery of bilateral endocervical-like mucinous borderline tumors in normal-sized ovaries. Tumor implants were also present in the mesosalpinx and a pelvic lymph node. We hypothesize that the abdominal wall metastasis resulted from seeding at the time of a prior exploratory laparotomy for trauma, before the ovarian tumors were discovered. We present evidence to support our theory of mechanical implantation of borderline tumor and explore other mechanisms leading to extraovarian mucinous neoplastic involvement.
