Tuba ovarian abscesses formation from decidualized ovarian endometrioma after appendiceal endometriosis presenting as acute appendicitis in pregnancy

Acute appendicitis with appendicial endometriosis is a very infrequently encountered condition during pregnancy. Decidualization is the hypertrophy of endometrial stromal cells by the effect of progesterone. Similarly, in pregnancy, ectopic stromal endometrial cells in endometriosis can also be transformed by the same mechanism and ectopic decidua [deciduosis] may occur. Here we report a 30 year old pregnant woman presenting twice with acute abdominal symptoms requiring surgery for appendicial and ovarian endometriosis and deciduosis. We emphasize that deciudualized endometriosis may first present during pregnancy with acute abdomen necessitating emergency laparotomy and complicating the course of gestation. To our knowledge only 9 cases in which decidualized endometriotic tissue causing acute abdomen necessitating surgery during pregnancy were reported in the literature. What makes our case special is that the patient needed two laparotomies during the pregnancy period which was a very stressful situation for both the patient and the physicians

Expression of matrix metalloproteinase-2 and survivin in endometrioid and nonendometrioid endometrial cancers and clinicopathologic significance / 부인종양

OBJECTIVE: To determine matrix metalloproteinase-2 and survivin expressions in endometrial cancers, their relation to clinical and histologic parameters and to investigate any difference in the expression of these markers between endometrioid and nonendometrioid cancers. METHODS: Ninety-five patients with endometrial cancer, were included. Matrix metalloproteinase-2 and survivin expressions were analyzed immunohistochemically from paraffin-embedded tissues by using specific monoclonal antibodies. RESULTS: Survivin nuclear expression was higher in endometrioid cancer as compared to nonendometrioid cancer (p=0.040), but there was no difference for cytoplasmic survivin and matrix metalloproteinase-2 expressions between type I and type II carcinomas. Survivin cytoplasmic staining was significantly lower in patients with deep myometrial invasion (p=0.038). Nuclear expression of survivin is decreased in histologic grade 3 tumors compared to grade 1 and 2 tumors (p=0.013), but there is no difference between grade 1 and 2. We did not find any statistically significant difference between survivin or matrix metalloproteinase-2 expressions and survival. CONCLUSION: Survivin and matrix metalloproteinase-2 are present in endometrioid and nonendometrioid cancers. Grade 1 and 2 tumors and carcinomas having myometrial invasion less than 50% have higher survivin expression. These results supports that, survivin may play an important role in early stage tumors and early phases of tumor development. We did not find any association between matrix metalloproteinase-2 expression and classical prognostic factors in endometrial cancer and both proteins were not associated with survival.
