Retrorectal Dermoid Cyst

Abstract

Background: Retrorectal cyst are rare lesions. Their clinical presentation is nonspecific, thus hampering their detection and frequently leading to misdiagnosis. According to their origin and histopathologic features, rectorectal cysts are classified as epidermoid, dermoid, enteric (tailgut cysts and cystic rectal duplication), and neurenteric cysts. Here we present the clinical, radiological and surgical findings in a case with a retrorectal dermoid cyst. Case Report: A 47-year-old male patient presented with rectal fullness and pain. MRI and CT studies revealed a noncalcified, unilocular, cystic mass lesion with well-defined borders. On MRI, self-contained fat spheres were detected inside the cyst. The cyst was excised completely by laparotomy. Pathological assessment revealed a dermoid cyst. The patient’s postoperative period was uneventful, and there was no recurrence during a 2-year follow-up. Conclusion: Complete surgical excision is indicated to establish the diagnosis and avoid complications of retrorectal cysts.

“…12 On the other end, patients may present with septic complications, including chemical peritonitis due to tumour rupture or abscess formation. [13][14][15] Patients also may present with chemical peritonitis related to dermoid rupture. 4,8 Chronic infection of dermoid cysts is a known complication with associated local abscess and fistulous tract formation to adjacent structures, including the skin.…”

“…4,8 Chronic infection of dermoid cysts is a known complication with associated local abscess and fistulous tract formation to adjacent structures, including the skin. 12,15 From here, a detailed physical exam, including a neurologic exam to assess for neurologic deficiency, and a digital rectal examination is vital and usually demonstrates an intact rectal mucosa with a posterior extra rectal bulge displacing the posterior rectal wall anteriorly. 11 The importance of digital rectal examination is evident for surgical planning.…”

“…Patients also may present with chemical peritonitis related to dermoid rupture ( [4 , 8] . Chronic infection of dermoid cysts is a known complication with associated local abscess and fistulous tract formation to adjacent structures, including the skin [12 , 15] . In this case, the patient was initially diagnosed with a chronic prostate abscess without consideration for an MCT even though he lacked infectious symptoms and had essentially negative cultures.…”
