A case study is reported of incomplete excision of a sessile leiomyoma
of the posterior cervix followed by rapid tumor growth of the same re
gion in a pregnancy commencing 2 months later, Cesarean section for pl
acenta previa was followed 10 days later by hysterectomy for massive h
emorrhage. The tumor was considered, following multiple review, to be
a leiomyoma of the cervix with mitosis consistent with recent pregnanc
y, Widespread peritoneal recurrence occurred within 3 months requiring
further laparotomy for excision of widespread tumor and ligation of i
nternal iliac arteries, Death occurred 4 weeks later with widespread p
eritoneal occurrence, No postmortem was performed, The case emphasizes
the rare potential for malignant change in histologically benign leio
myomas with no indications to this potential apart from biological beh
avior. (C) 1996 Academic Press, Inc.
