Retrorektal kistler gelisimsel kistler olup, kökenlerine ve histopatolojik özelliklerine göre; dermoid kist, rektal duplikasyon kistleri ve kistik hamartomlar (Tailgut kistleri) olarak siniflandirilabilirler. Dermoid kistler çogunlukla overian yerlesim göstermekle beraber, mediastende, retroperitoneal bölgede ve nadiren retrorektal lokalizasyonda da görülebilmektedirler. Retrorektal kistler genellikle asemptomatik olsalar da rektal dolgunluk, defekasyon düzensizlikleri, karin agrisi ve disparoni gibi sikayetlere neden olabilirler. Çogunlukla rutin pelvik muayene ve görüntüleme yöntemleri ile rastlantisal olarak taninirlar. Genellikle benign lezyonlar olmalarina ragmen malign transformasyon ve enfeksiyon gelisme riskleri nedeni ile tani konuldugunda cerrahi olarak çikarilmalari gerekmektedir. Bu yazida eriskin bayan hastada, rutin pelvik muayene esnasinda fark edilen ve cerrahi olarak çikarilan retrorektal dermoid kistin tani ve tedavisi irdelenmistir
Retrorectal cysts are developmental cysts, and according to their origin and histopathological features, they are classified as dermoid cysts, rectal duplication cysts and cystic hamartomas (tailgut cysts). Although dermoid cysts have mostly ovarian localization, they can be seen in mediastinal, retroperitoneal, and rarely, retrorectal localizations. Although retrorectal cysts are usually asymptomatic, they might cause problems such as rectal fullness, defecation disorders, abdominal pain, and dyspareunia. They are incidentally diagnosed mostly on routine pelvic examinations and with imaging methods. Though they are usually benign lesions, after the diagnosis, they should be surgically removed because of the risks of malignant transformation and infection. In this article, we examined the diagnosis and treatment of a retrorectal dermoid cyst, which was discovered during the routine pelvic examination and surgically removed from an adult female patient
