Review
Facial teratomas are uncommon tumours in children that distort the face and may be associated with functional problems. They are less common than cervical teratomas though they are often grouped together and considered an emergency due to their tendency to cause respiratory compromise. They tend to be large and cause cosmetic issues; hence usually noticed early and medical help sought promptly by parents. The close proximity of facial teratomas to structures like eyes, parotid gland, facial nerve, vessels and brain makes them challenging and requires a patient and meticulous exploration during surgery. We present a case of an 11 month old girl with left sided temporal teratoma. Well planning of the incision and complete excision of the tumour with careful sparing of the facial nerves and parotid gland yielded good result.

INTRODUCTION
Endobronchial teratoma is sporadic disease. The study aims to present a case with endobronchial teratoma with a brief literature review. A 26-year-old male presented with a history of frequent attacks of chest infection for the last two years. Chest examination showed diffuse wheeze all over the left side of the chest. Chest x.ray showed opacification involving all of the left side of the chest with elevated left hemi diaphragm while computed tomography scan confirmed complete collapse of the left lung with consolidations and air bronchogram. Flexible bronchoscopy showed near-total obstruction of the left main bronchus. Under general anesthesia, left pneumonectomy was performed. The result of the histopathological examinataion showed mature teratoma.
CONCLUSION
Endobronchial teratoma is an exceedingly rare type of intrathoracic teratoma that mainly affects males and is usually diagnosed at the 3rd decade of life; lobectomy or pneumonectomy are optimal managements for these cases.

Melanosis is a rare benign entity defined by the deposition of brownish-black pigment in a wide variety of organs especially the gastrointestinal tract, peritoneum, fallopian tubes and ovaries. Melanosis of the fallopian tube is widely known as pigmentosis tubae. Literature has mentioned ovarian teratomas and serous cystadenomas to be associated with the ovarian and peritoneal melanosis. We report five such cases of tubo-ovarian melanosis. The cases include mature teratoma and serous cystadenoma as well as melanosis of the fallopian tubes with otherwise normal ovarian histology. The importance of recognising this entity lies in its differential diagnosis.

INTRODUCTION AND IMPORTANCE
Mediastinal teratoma is the most common mediastinal germ cell tumor. Mature mediastinal teratomas are infrequent and often found incidentally.
CASE PRESENTATION
We report the case of a 14-year-old girl who was presented dyspnea for 2 years. A computed tomography of the chest revealed a 19 cm heterogenous right-sided anterior mediastinal mass suggesting mature teratoma. The mass compressed vital structures. The tumor was considered resectable. By hemiclamshell approach, we punctured the tumor and aspirated its contents. The tumor was totally resected en bloc with a cuff of pericardium, phrenic nerve and azygos vena. The pericardial defect was repaired using Mersilene mesh. Histopathology of the tumor revealed a mature cystic teratoma. Postoperative course was uneventful.
CLINICAL DISCUSSION
Complete surgical excision is the treatment of choice for mediastinal mature teratoma. The choice of incision for removing the tumor depend on the tumor size, location and the relashionships with the associated vital structures. Lengthy incisions were required for the safe mobilization of the tumor. In addition, contents aspiration through a small incision in the giant tumor wall helped improve tumor mobilization.
CONCLUSION
Appropriate surgical strategy for a well selected case maintains functional status and results total tumor resection.

Review
BACKGROUND
Mature teratoma is the most common germ cell tumor as it represents 95% of germ cell tumors. Although common in children and young adults, ovarian teratoma can occur at any age. Mature teratomas are composed of mature tissues representing elements derived from more than one embryonic germ layer (ectoderm, mesoderm, and endoderm), with ectodermal derivatives being the usual predominant component; however, the finding of a well-differentiated cerebellum is extremely rare.
CASE PRESENTATION
A 20-year-old Saudi female presented to the emergency department with severe abdominal pain of 1-day duration. Pelvic ultrasound showed a large ovoid- to bilobed-shaped cystic pelvic structure extending to the lower abdomen. The patient underwent left ovarian cystectomy. Microscopic examination showed a cyst wall with skin tissue, including adnexal structures (sebaceous glands), a well-differentiated cerebellum, and mature glial tissue. After extensive sampling, no immature component was identified. Thus, the final diagnosis of a mature cystic teratoma with well-differentiated cerebellum was established. The patient was well postoperatively and was discharged in a stable condition.
CONCLUSION
We report this case of well-differentiated cerebellum within ovarian teratoma to expand the pool of cases reported in literature of this extremely rare entity, as only 22 cases with such findings have been reported in literature to the best of our knowledge. This finding poses a diagnostic challenge to the pathologist due to its rarity and its similarity to immature teratoma. We thus emphasize that thorough sampling of ovarian teratoma is of paramount importance and to keep the aforementioned diagnosis in mind and not confuse it with immature elements, especially in intraoperative consultation and frozen sections.

OBJECTIVE
The occurrence of posterior fossa teratomas in adulthood is extremely rare. In this study, we aimed to report our experience with two cases of posterior fossa mature teratoma in adults who underwent surgical resection. We also performed a systematic review of published papers available to date.
METHODS
We retrospectively reviewed the electronic medical records of patients who had onset of posterior fossa teratomas in adulthood at our institute between 1995 and 2020. We evaluated the clinical, radiographic, and pathological features of mature teratomas at the posterior fossa in adulthood. Furthermore, we searched the PubMed, EMBASE, and Web of Science database and reviewed published articles.
RESULTS
We found 507 articles on database review; of them, 102 were duplicates and 389 were excluded based on the inclusion criteria. Finally, 16 cases of posterior fossa from the web search and related articles. Subsequently, we added two cases that underwent surgery at our institute. We analyzed a total of 18 cases of mature teratomas. Headache was the most common (55.6%) symptom. The teratomas showed heterogeneous signals on magnetic resonance imaging. Thirteen patients (72.2%) had lesion at midline, five patients (27.8%) had calcification. Surgical resection was performed in all patients. No studies reported recurrence after resection.
CONCLUSION
The occurrence of posterior fossa teratomas in adulthood is difficult to diagnose at the initial stage. Radiographic diagnosis alone can lead to misdiagnosis. Pathological confirmation is essential. Surgical resection is a curative option for posterior fossa teratomas in adulthood.

The teratomas are derived neoplasms of totipotent embryonic cells and are extremely rare. We reported a Renal tumor on the right in a 36 years old patient, incidentally detected by imaging exams as a large and complex cystic lesion. Radical nephrectomy was performed with histopathological diagnosis of mature teratoma.

BACKGROUND
Benign mature teratomas are the most common type of anterior mediastinal germ cell tumor. Mature intrapericardial teratomas are generally diagnosed during infancy because of symptoms of cardiac compression. In contrast, mature adult intrapericardial teratomas are extremely rare, accounting for less than 1% of mature intrapericardial teratomas. We describe herein a case of a mature intrapericardial teratoma in an asymptomatic adult.
CASE PRESENTATION
A 52-year-old woman was found by computed tomography during a health checkup to have an anterior mediastinal mass. She was asymptomatic and hemodynamically stable with no evidence of heart failure. The preoperative provisional radiological diagnosis was a mature intrapericardial teratoma. A median sternotomy revealed an approximately 5-cm diameter protruding intrapericardial mass with a smooth surface. The mass was completely resected. Histopathological examination resulted in a diagnosis of a mature intrapericardial teratoma. The patient did well and has no evidence of recurrence 5 years after surgery.
CONCLUSIONS
Mature intrapericardial teratomas in adults are extremely rare. Given the risks of malignant transformation, rupture, compression of the heart, and infection, excision is indicated to prevent development of serious manifestations.

Dermoid cyst is a congenital and benign disease with most occur on the head and neck. It is rarely that occur on the nasal tip and nasal septum at same time and rarely repair of using nasal septum mucosa. The authors treated a child with dermoid cyst in the nasal tip and septum. Only the dermoid cyst at the tip of the nose caused the change of appearance. Dermoid cyst of nasal septum did not cause any clinical symptoms. She underwent excision of the dermoid cyst at the tip of the nose and endoscopic surgery for the dermoid cyst in the nasal septum and used the nasal septum mucosa for repair at the same time. After 6 months of recovery, the appearance of the nasal tip recovered well without obvious scar, the nasal septum area recovered well, and the local stoma was unobstructed without recurrence. The authors found that this kind of nasal septal cyst with no clinical symptoms can achieve good therapeutic effect through endoscopic surgery and repair of using nasal septum mucosa, with less damage, rapid recovery, and good prognosis.
