Dobroćudni multicistični peritonejski mezoteliom s oponašanjem ginekološke patologije

Benign multicystic peritoneal mesothelioma is a rare pathology that arises from the abdominal peritoneum. It has an affinity to develop on the surfaces of pelvic viscera. It predominantly occurs in women of reproductive age. The most used form of treatment is complete surgical removal. We report a case of a a 21-year-old female patient who presented with unclear diffuse abdominal pain. Transvaginal ultrasound and magnetic resonance imaging of the abdomen and pelvis revealed multiple functional cysts in the projection of the right and left ovary and free fluid in the pouch of Douglas. Laparoscopy was performed and multicystic tumor with thin, smooth walls, filled with clear serous content was found in lesser pelvis spreading to the left paracolic region and under the spleen. The multicystic mass was removed. Histologic examination revealed cystic formations filled with mucous content and formed from connective tissue outside and single row epithelium-mesothelium inside. Definitive diagnosis was benign multicystic mesothelioma of the abdominal peritoneum. The patient was well at one year follow-up.Dobroćudni multicistični peritonejski mezoteliom je rijetka bolest koja nastaje iz abdominalnog peritoneja. Obično se razvija na zdjeličnom peritoneju, najčešće u žena generativne dobi. Najuobičajeniji način liječenja je potpuno kirurško uklanjanje. Prikazujemo slučaj 21-godišnje djevojke koja nam se javila s nejasnom difuznom boli. Transvaginalni ultrazvuk i magnetna rezonanca trbuha i zdjelice otkrili su višestruke funkcionalne ciste u projekciji desnog i lijevog jajnika i u Douglasovu prostoru. Učinjena je laparoskopija i nađen je multicistični tumor s tankim glatkim zidovima ispunjenim bistrom seroznom tekućinom u maloj zdjelici, koji se širio u lijevu parakoličnu regiju i ispod slezene. Multicistična masa je uklonjena. Patohistološka analiza je otkrila cistične formacije ispunjene sluzi i građene od vezivnog tkiva izvana i jednorednim epitelmezotelom iznutra. Konačna dijagnoza je bila dobroćudni multicistični mezoteliom abdominalnog peritoneja. Bolesnica se redovito kontrolira bez znakova bolesti
