PURPOSE A retrorectal developmental cyst (tailgut cyst, epidermoid cyst, dermoid cyst, teratoma, and duplication) is very rare disease, and the symptoms are not characteristic so that sometimes this disease is still misdiagnosed as a supralevator abscess or a complex anal fistula. We would like to present a clinical approach to this disease. METHODS We retrospectively examined the charts of 1...

Epidermoid cysts, true dermoid cysts and teratoid cysts compose the spectrum of cystic teratomas, which are defined as neoplasms whose tissue are derivatives of more than one germ layer, foreign to that part of the body from which the tumor arises. Epidermoid cysts of the floor of the mouth are rare lesions and are much less common than dermoid cysts in the head and neck. This case reports a 43...

BACKGROUND Cranial dermal sinuses are rare and occur most frequently in the posterior fossa and along the midline. Likewise, supratentorial dermoid cysts are very uncommon. METHOD We report a unique case of an adult female patient with both a supratentorial dermoid cyst and an incomplete dermal sinus tract. RESULTS The patient is a 31-year-old female, who presented with a new onset complex ...

BACKGROUND Dermoid cyst is the most frequent benign ovarian tumor. Spillage of cyst contents during surgery is common and can rarely lead to chemical peritonitis. CASE REPORT A patient presented 3 days after attempted laparoscopic removal of bilateral dermoid cysts. On examination, she had a low-grade fever, rebound tenderness with guarding, and a markedly elevated white blood cell count. A ...

Dermoid cysts of the head and neck are rare lesions. An unusual dermoid cyst in the subcutaneous tissue of the mastoid region is easily confused with lymph node abnormalities; therefore, diagnosis and treatment are often challenging. We describe a 22-year-old male with an unusual dermoid cyst in the subcutaneous tissue of the mastoid region whose only complaint was a retroauricular lump, which ...

BACKGROUND Intraperitoneal spillage of dermoid cyst content, if not followed immediately by abundant peritoneal lavage, can cause a chemical peritonitis with subsequent adhesion formation. STUDY DESIGN We performed an open clinical study in a university hospital. Forty-four consecutive ovarian dermoid cysts were removed intact from 40 premenopausal women operated on between October 1993 and D...
