Developmental cysts as a source of perianal abscesses, sinuses and fistulas

Presacral epidermoid cyst: Report of a case

“…Developmental cysts include dermoid, epidermoid, and mucus-secreting cysts, and their presence is due to a certain developmental error during the formation of the embryo. 1 The generally accepted definition in describing an epidermoid cyst is as follows: an epidermoid cyst has stratified squamous epithelium with keratohyaline granules, but no skin appendages. 4 Most patients with presacral tumors complain of nonspecific symptoms, which generally depend on the local extent of the tumor, its size and site, and whether or not the parts are necrotic or infected.…”

“…An epidermoid cyst is one such lesion, and the etiology is due to a developmental error during the formation of the embryo. 1 The rarity of its occurrence and its anatomical site may make it difficult for the examining physician to diagnose and treat this disorder. Of a variety of surgical approaches advocated for presacral tumors, 2,3 a growing number of transsacral approaches have recently been selected.…”

Tumors of the Retrorectal Space

“…15 As a result, this dimple is commonly discovered in association with drainage, leading to a misdiagnosis of fistula, sinus, or perianal abscess, and a delay in definitive treatment because of the failure to appreciate the underlying pathology. 1,18 In fact, many retrorectal masses are discovered only after a CT scan is obtained for refractory perianal suppuration or fistula. The clinician should always keep the possibility of a retrorectal mass in the differential diagnosis for any patient with recurring perianal pathology without a clear source.…”

A Complicated Case of Pregnancy Involving a Presacral Epidermoid Cyst

“…A precise classification and description of each feature have been described in detail previously 1 .…”

“…Presacral or retrorectal developmental cysts are rare 1 . The presacral epidermoid cyst, which is a developmental cyst, arises from remnants of embryonic tissues and is detected most often in women of reproductive age.…”
