Review
RATIONALE
Most of the mature teratomas are found in the ovaries. Extragonadal teratomas are extremely rare. To date, there are only a handful of reports of uterine cervical teratomas documented in the English literature.
PATIENT CONCERNS
Herein we describe a rare case of a 40-year-old patient who was presented to our hospital for a cervical polypoid mass, which was finally confirmed to be mature solid teratoma in uterine cervix.
DIAGNOSES
Histological examination of the polypoid mass was found to consist of ciliated pseudostratified columnar respiratory epithelium, intestinal epithelium and smooth muscle tissue, adipose tissue and mature glial component, epidermis, and skin adnexa. Meanwhile, no history of abortion, dilatation, and curettage was present in this patient, so implantation of fetal tissue was excluded. Therefore, we make a diagnosis of uterine cervical mature teratoma.
INTERVENTIONS
Tumorectomy was performed after discovering the cervical polypoid mass.
OUTCOMES
The patient had been followed-up for next 3 months after surgery and no recurrence was documented until now.
LESSONS
Though teratomas of the uterine cervix are extremely rare, more attention should be paid on this rare but possible tumor for appropriate treatment in these patients.

While mature cystic teratomas are relatively common ovarian neoplasms typically comprising of multiple embryologic cell types, a specific monodermal subtype involving thyroid tissue, struma ovarii, can rarely be seen. This case reviews typical imaging characteristics with MRI and ultrasound of struma ovarii and details possible complications from these masses with intraoperative and histologic correlation.

OBJECTIVES
The aim of this multicentre retrospective study was to review the clinical data, outcomes and histopathological features of cats that had been treated for ocular surface dermoids.
METHODS
Thirteen cats from various private practices in France with a clinical diagnosis of ocular surface dermoid were included in the study.
RESULTS
The mean age of the study population at the time of diagnosis was 5 months. There were nine males and four females. Three different breeds were domestic shorthair (n = 7), Birman (n = 4) and Havana Brown (n = 2). Two of the four Birmans were related (same sire). The two Havana Browns were also related (same sire). All of the dermoids were unilateral. Five of the dermoids were strictly conjunctival. Four affected both the conjunctiva and the cornea. Three affected both the conjunctiva and the eyelid, and one was strictly corneal. They were located in various positions: temporal (n = 9), inferonasal (n = 1), dorsonasal (n = 1) and dorsotemporal (n = 1). The last dermoid was heterogeneous and involved the nasal, dorsal and temporal quadrants. Concurrent eye diseases were observed in five patients: four cats exhibited associated eyelid agenesis and one cat exhibited persistent iris-to-iris pupillary membranes. Ten dermoids were surgically excised with no recurrences. Surgery was not performed for three cats: one cat died a few days after diagnosis and two cats were lost to follow-up after initial presentation.
CONCLUSIONS AND RELEVANCE
Ocular surface dermoids are a rare condition in cats that can be treated successfully by surgical excision. Although our study reports only a small number of cases, the observation of ocular surface dermoids in two related cats in two different breeds indicates that genetic transmission is likely.

OBJECTIVE
Dermoid is a rare disease located in the head and neck and only sporadic cases were previously reported. Surgery with different operational paths is the best solution to the disease. We aimed to analyze the clinical characteristics and outcomes of surgical approach for treating dermoid originated from the middle ear and Eustachian tube.
METHODS
In this retrospective case series, four cases of dermoids of the middle ear and Eustachian tube, treated by endoscopic-assisted surgical approach were reviewed and analyzed.
RESULTS
Patients' ages ranged from 7 months to 16 years. All cases involved the middle ear, eustachian tube, and the parapharyngeal space. Postoperative follow-up ranged from 6 months to 11 years. No facial nerve paralysis was observed during or after surgeries. Treatment was efficient in the four cases, with no residual symptoms during post-operative follow-up.
CONCLUSIONS
Dermoid of the middle ear involving the eustachian tube usually appears in children of early age. Surgical resection with assistance of endoscope has satisfying outcome for these cases.

Review
BACKGROUND
Mature cystic teratoma of the ovary is classified among the benign ovarian germ cell neoplasms, and its malignant transformation occurs very rarely (in about 2%). As a result of nonspecific signs and symptoms, preoperative diagnosis of theses malignancies is a challenge to clinicians, resulting in delayed diagnosis (in advanced stages) and poor outcomes.
CASE PRESENTATION
We report the case of a 43-year-old Iranian woman with progressive distension of the abdomen and hypogastric pain, who was diagnosed with squamous cell carcinoma transformation in a mature cystic teratoma of the ovary confirmed by histopathology examination. Total abdominal hysterectomy, bilateral salpingooophorectomy, and comprehensive staging surgery were performed for the patient, and she was scheduled for chemotherapy after the surgery. She responded well to the treatment and is currently continuing her chemotherapy process.
CONCLUSION
There are a great number of reports in the literature regarding mature cystic teratoma of the ovary transformation into malignancy, so these neoplasms must be considered as a possible differential diagnosis and should be evaluated in older individuals with abdominal pain and palpable mass, or those with considerable tumor diameter and raised serum tumor markers.

Review
BACKGROUND
The ovary is the most common site of occurrence of mature cystic teratomas (dermoid cysts). These are the most common ovarian germ cell tumor in the reproductive age group, accounting for 10-20% of all ovarian neoplasms, with a 1-2% risk of malignancy. A cecal dermoid cyst is a rare entity with only ten cases having been reported so far, eight of which could be retrieved as the rest were reported in different languages. None of these cases were managed laparoscopically. Here we present the first case of cecal dermoid managed laparoscopically.
CASE PRESENTATION
A 35-year-old nulliparous Indian Hindu woman presented with complaints of on and off abdominal pain for 10 months. The abdominal examination revealed a well-defined mass of about 10 × 5 cm size, palpable in the right iliac fossa. On sonography, it was suggestive of a right-sided ovarian dermoid cyst. The lesion measured 10 × 7 × 5 cm on a contrast-enhanced computed tomogram (CT) scan. It was well defined and hypodense and located in the right lower abdomen. The ovarian tumor markers were normal. On laparoscopy, the uterus, bilateral tubes, and ovaries were found to be healthy. The cyst was seen arising from the right medial wall of the cecum at the ileocecal junction, which was excised laparoscopically. Histopathological study revealed it to be a mature cystic teratoma.
CONCLUSION
Ovarian mature cystic teratoma commonly has an indolent course and can present with palpable abdominal mass, pain, or vomiting due to complications like torsion, hemorrhage, or infection. Alternatively, these cysts can be asymptomatic and incidentally detected. Clinicians should be aware of the variety of presentations of dermoid cysts of the bowel as well as mesentery. The exact location of the teratoma eluded us till the laparoscopy despite adequate imaging including a contrast-enhanced CT scan having been performed preoperatively. We are reporting this as it is a rare entity, and this knowledge will help gynecologists and surgeons make an appropriate surgical decision.

The literature on long-term outcome after resection of intraspinal dermoid and epidermoid tumors is limited. The purpose of this study was to review the progression-free survival (PFS), overall survival (OS), and long-term outcome in a consecutive series of 57 patients with intraspinal dermoid and epidermoid tumors. Retrospective study. A total of 57 patients who underwent surgery at our institution between 2002 and 2010 were reviewed. Patients outcome were determined using the Japanese Orthopaedic Association score (JOA) and the McCormick score. The follow-up data were 100% complete and the median follow-up time was 9.2 years. Gross total resection was performed in 21 patients (36.84%) and subtotal resection in 36 patients (63.16%). The PFS and OS at 8 years were 78.95% and 100% respectively. A good outcome was observed in 56.14% of patients based on the JOA and McCormick score. The univariate analysis showed that a tumor size of more than 4 cm, subtotal resection and sphincter disturbances were the influencing factors of poor outcome. The gold standard treatment for intraspinal tumors is gross total resection, but the operation needs to protect the remaining nerve function as much as possible and follow-up should be focused on patients with a high risk of poor outcome.
