Abstract
A 36-year-old female patient who had noticed a bulge in her right inguinal area since 5 years prior, came to our hospital complaining of pain in the area since 3 days ago. The bulge could not be reduced. A manual reduction was tried at the clinic without success. Echo study revealed a lesion of 4cm in size with multiple anechoic area. An operation was performed with diagnosis of an incarcerated inguinal hernia with suspicion of an ovary as its content. A tumor with thick wall was connected to the hernia sac at the level of the pubic tubercle and the internal ring. The tumor was 9 × 4cm in size, cystic with yellowish serous fluid. Pathohistological study revealed a nodular or papillary growth of mesothelial cells with weak nuclear atypism. Immunostaining was HBME-1 positive, calretinin and p 53 negative, MIB-1 positive in 0.1 % and the presence of hyperplasia of mesothelium was suspected. Together with macroscopic findings of the excised specimen, the diagnosis of multilocular mesothelial cyst was made. Postoperatively no recurrence of the cyst was observed in 18 months of follow-up. This is a rare case, but its possibility should be considered as a differential diagnosis in case of multilocular disease in a echo study. Also the history of trauma as the cause should be checked at the time of the interview of the patient.
