Ovarian carcinoma commonly has an insidious onset. By the time the dia
gnosis is made, advanced disease is usually present. Rarely does a pat
ient have acute symptoms which require immediate medical attention and
lead to the correct diagnosis. A 40-year-old white female presented w
ith lower abdominal pain, nausea, and light-headedness. Physical exami
nation revealed a markedly tender lower abdomen with the right lower q
uadrant slightly more tender than the left. Hemoglobin level was noted
to have decreased 2.6 g/dl over 16 hr. At exploratory laparotomy, 150
0 cc of blood and a ruptured right ovarian mass were found. Pathologic
analysis revealed a malignant mixed mesodermal tumor of the right ova
ry and an endometrioma of the left ovary. In conclusion, ovarian carci
noma may present as an acute abdomen because of intra-abdominal hemorr
hage. It should be part of the differential diagnosis in a woman with
an acute surgical abdomen and a hemoperitoneum. (C) 1994 Academic Pres
