Endometriosis coexisting with a dermoid cyst of the ovary is extraordinarily rare, although both these benign conditions are said to be common in women in the reproductive age group. There are only two previous case reports,which is evident from our literature review from January 1960 through January 2010. Acute abdomen is one of the greatest diagnostic challenges and easily ignored by the clinicians to exclude the possibility of gynecologic illness. A 35-year-old woman was referred by the doctor in Family clinic. She experienced a three-day period of severe right lower abdominal pain and intermittent vomiting. Ultrasonography identified a bilocular, cystic, hypoechoic, and hyperechoic tumor, 7 cm × 6 cm × 6 cm in the right adnexal region. Laparoscopic cystectomy was performed under the impression of ovarian cyst with torsion or hemorrhage. The frozen section was benign and appendiceal status was adequate. Histopathologic examination described an ovarian cyst composed of endometrial-type lining with stromacells (endometriosis) and benign teratoma tissue with plenty of skin appendages and sebaceous glands. We report this unusual and interesting ovarian mass to remind physicians that the usage of the Endobag after cystectomy, the benefits on minimizing operative time, spilled opportunity, and postoperative complications. Laparoscopic techniques for large ovarian masses might be considered. The experience of the surgeon is also very important to prevent misdiagnosis or complication. Further follow up is mandatory for this simultaneous finding of ovarian endometriosis with coincidental dermoid cyst as a separate pathology in single ovary of such a nature. It also presents a challenge to the clinicians and to the pathologists.

A dermoid cyst of the head and neck region is a relatively infrequent occurrence and accounts for only 6.9% of all dermoid cysts. Its anatomical distribution is the orbit, floor of the mouth, other midline and nose in the order of frequency. A dermoid cyst of the parotid gland is extremely rare, and due to this and the absence of pathognomonic findings, it is often difficult to diagnose preoperatively. Thus thorough and careful examination including ultrasonic study is needed to evaluate this lesion. It must be differentiated from malignant tumors and other cystic lesions. Dermoid cysts usually recur after simple excision, so it is mandatory to excise it completely with a parotidectomy. This paper presents two cases of parotid gland dermoid cyst with a brief review of the literature.

Dermoid tumors in the medial canthal area are rare, but when present they commonly adhere to the lacrimal canaliculi. Three patients presented with a mass in the medial canthal area. The authors performed excisional biopsies, and the masses were diagnosed as dermoid tumors. In two patients, canalicular lacerations were found after mass excision, which suggested that the masses had been firmly adherent to the lacrimal canaliculi. The lacerated canaliculi were repaired after bicanalicular silicone intubation. In the remaining patient, lacrimal silicone intubation was performed at the beginning of surgery, and the mass was successfully dissected from the canaliculi, leaving them intact. Excision of dermoid tumors in the medial canthal area requires careful dissection to avoid canalicular laceration. Bicanalicular silicone intubation at the beginning of surgery is helpful for the identification of the canaliculi and for the prevention of canalicular laceration during dermoid tumor excision.

Dermoid sinuses and meningoceles are seldom encountered in the cervical region. Besides, to the best of our knowledge, the coexistence of these types of congenital abnormalities with recurrent meningitis, as well as with mirror movement, has never been reported before. A 14-year-old female with the diagnosis of recurrent meningitis was referred to our clinic from the Department of Infectious Diseases. She had a cervical meningocele mass that was leaking cerebro-spinal fluid (CSF) and an associated mirror movement symptom. Spina bifida, dermoid sinus and meningocele lesions were demonstrated at the C2 level on computed tomography (CT) and magnetic resonance imaging (MRI). She underwent an operation to remove the sinus tract together with the sac, and at the same time the tethered cord between the sac base and the distal end of the spinal cord was detached. The diagnosis of dermoid sinus and meningocele was confirmed histopathologically. These kinds of congenital pathologies in the cervical region may also predispose the patient to other diseases or symptoms. Herein, a case of meningocele associated with cervical dermoid sinus tract which presented with recurrent meningitis and a rare manifestation of mirror movement is discussed. Neurosurgeons should consider the possible coexistence of mirror movement and recurrent meningitis in the treatment of these types of congenital abnormalities.
