BACKGROUND-
The incidence of Dermoid ovarian cyst is 15-20% of all ovarian neoplasm, which is a common entity.
Mesenteric cyst is one of the very rare entities with incidence of 1 in 2,00,000 and Mesenteric Dermoid cyst are even rarer entity amongst all of the mesenteric cysts with incidence of 1:1,00,000.
Both mesenteric cyst & mesenteric dermoid cyst have good prognosis.
Here we report a rare abdominal tumor, which was initially diagnosed clinically as an ovarian dermoid cyst but operative and histology revealed mesenteric dermoid cyst.
Case: A 36-year multipara presented with abdomino-pelvic mass gradually increasing in size since 1 year with recent onset of abdominal pain..
Physical examination revealed abdominal mass upto 26cm*20cm size, globular, nontender, variegated surface, mobile, cystic to solid in consistency.
CECT abdomen & pelvis revealed a large well defined, abdomino-pelvic 14.42123.1 cm heterogeneous mass with areas of fat density and calcifications, suggestive of neoplastic mass ,likely teratoma.
Tumor markers : AFP, B-hCG and CA-125 all within normal limit.
Patient was managed surgically after necessary pre- operative investigations.
Laparotomy findings revealed a huge solid mesenteric mass (22cm*20cm) weighing 6.5kgs. Small bowel & both ovaries were adhered & was separated from mass by fine dissection. Postoperative period was uneventful.
Histopathological examination showed mature cartilage, osteoid formation, fibro-adipose connective tissue, focal lymphoid aggregates, congested blood vessels, focal mature neuronal component and no immature elements seen, confirming dermoid cyst.
