Abstract
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, benign neoplasm of neural crest origin that predominantly involves the craniofacial region, involvement of the epididymis being extremely rare, with about 30 cases reported. We report an unusual case of a 5-month-old male with MNTI in the epididymis. The patient underwent orchiectomy. Half a year later, there was no sign of recurrence. Whether preoperative examination or intraoperative frozen examination, the tumor may easily be misdiagnosed as malignancy. Melanotic neuroectodermal tumor of infancy should be included in differential diagnosis in infants presenting with fast-growing scrotal swelling.

Abstract
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare benign neoplasm that can be mistaken for malignancies due to its unfamiliarity among clinicians and aggressive clinical appearance. We herein contributed by reporting an additional case of MNTI characterized by an extensive extraoral protrusion in a 2-month-old infant. The lesion involved the anterior maxilla, cheek, and infraorbital region, resulting the displacement of the nose to the contralateral side, and measuring approximately 10 cm in size. Surgical resection of the lesion was performed. After a 6-month follow-up, the patient has shown no evidence of recurrence. The rapid growth and aggressive behavior of MNTI emphasize the importance of an early diagnosis and prompt intervention in order to achieve favorable outcomes.

Abstract
Melanotic neuroectodermal tumor of infancy (MNTI) is an uncommon pigmented neural crest tumor primarily found in infants. We presented a case report of successful surgical management of MNTI in an 11-month-old female. A total of 178 articles discussing 249 cases of MNTI were identified through literature search. Literature review of 250 cases of MNTI including the current case report was conducted considering study parameters such as age and gender of the patient, location of the lesion, levels of vanillylmandelic acid, management options, and outcome after treatment. Statistical review of the data showed that MNTI predominantly affects the anterior maxilla in infants less than six months of age. Recurrence of the lesion shows a significant association with age of the individual and treatment method employed. This study reports a 2.4% mortality rate, 2% malignancy rate, and a recurrence rate of 15.2%, with recurrence times ranging from 15 days to 20 months. We advocate a minimum follow-up of four months to two years to monitor recurrence.

Abstract
Melanotic neuroectodermal tumour of infancy (MNTI) is a locally aggressive neoplasm of neural crest origin. It is primarily a paediatric tumour, and 95% of the cases occur in children below 1 year. The tumour mainly affects the head and neck region. It shows a predilection for the craniofacial sites and the most common site affected is anterior maxilla. Microscopically, it is characterized by a biphasic population of neuroblastic cells and pigmented epithelial cells. Although generally considered as a benign tumour, it can invade the adjacent muscle and bone, causing destruction of the involved site. The rapidity in growth and the aggressive clinical behaviour of the tumour can be deceptive and hence lack of familiarity with the clinical characteristics of the tumour may often lead to an erroneous diagnosis of malignancy. The treatment of choice for MNTI is excision, and it is usually curative. Extensive surgery in a child may interfere with the normal growth and development of the facial structures and reconstruction can be very challenging in infants. Hence, early diagnosis is critical for the effective management. Clinical findings, histopathological features, and differential diagnosis of a classic case of melanotic neuroectodermal tumour of infancy are discussed.

Abstract
Melanotic neuroectodermal tumors of infancy (MNTI) are a rare type of benign tumor that affects the head and neck region. MNTI represents (68-80%) of the tumors in the maxillary region. This tumor is usually located in the alveolar crest, skull, mandible, and brain. Although this tumor is considered benign, it can grow rapidly, with a high risk of recurrence and interference with functions of infancy, such as feeding and breathing. It is also frequently harmful to the surrounding soft and hard tissues or adjacent sensitive vital structures. This study aimed to review the pathological, clinical presentation, and treatment of melanotic neuroectodermal tumors in infancy and the role of dentists in these cases.

Abstract
To the best of our knowledge, thus far there are no reported cases of melanotic neuroectodermal tumor of infancy (MNTI) with multiple complications. In this case report, we describe the clinical phenotype of MNTI in a 9-month-old female infant associated with tetralogy of Fallot (TOF), a congenital heart defect, and congenital hypothyroidism (CH). Our study showed that the growth of MNTI was delayed by a lower dosage of levothyroxine (L-T4) that was prescribed to treat CH because of the presence of TOF, a severe congenital heart disease. However, the standardized dosage of L-T4 improved thyroid function but stimulated the rapid growth of MNTI. Our report demonstrated that treatment with L-T4 affects the progression of MNTI. Our findings demonstrated the role of thyroid hormone in MNTI growth and progression. Furthermore, our study suggested that the treatment of co-morbidities in children with MNTI requires careful consideration of their effects on the growth and progression of MNTI.

Abstract
Melanotic neuroectodermal tumor of infancy is a rare pigmented pediatric tumor seen at craniofacial sites with the most common site being maxilla. This tumor arises from neural crest origin with a polyphenotypic expression of epithelial, neuroblastic, and melanotic markers. It is a locally aggressive tumor with rapid, expansile, and destructive growth. The tumor has fairly high chances of recurrence and malignant transformation, if not diagnosed and treated with time. There is no standard protocol for management owing to its rarity. Hereby, we present one such case of a 2-month-old male child with rapidly enlarging upper jaw swelling. The patient was treated with wide local excision, followed by two cycles of chemotherapy. The patient is in follow-up and doing well with no evidence of any local recurrence or metastasis till date.

Abstract
Melanotic neuro-ectodermal tumor of infancy (MNTI) is an extremely rare tumor. The purpose of this study was to describe the imaging features of maxillary bone MNTIs and introduce the key points for clinical diagnosis of MNTI. We retrospectively reviewed four patients with histology-proven MNTIs arising from the maxillary bone. All patients underwent ultrasonic inspections, CT and/or MR scanning. Combined with previously literature, the imaging features were comprehensively evaluated and analyzed. All MNTIs showed a firm, non-ulcerated rapidly-growing soft-tissue swelling with pigmented (blue-colored or black-colored or gray-colored) mucosa. The onset ages were younger than 6 month-old. CT images showed osteolytic or expansive bone destruction of the involved maxillae, fragmentary cortical bone, "free-floating" tooth germs, with or without spiculated/sunburst periosteal reaction. The tumor appeared lightly hyper-intense on T2-weighted sequences, while isointense or lightly hypo-intense or lightly hyper-intense signal on T1-weighted sequences. Enhanced images all displayed heterogeneous enhancement. No metastasis features of lymph nodes or abdominal organs were demonstrated by cervical and abdominal ultrasonic inspections. As a conclusion, accurate recognition of the imaging features of MNTI combined with history and clinical manifestations (early infancy, painless, firm, pigmented mucosa, non-ulcerating lesion) can provide clues for diagnosis of this rare entity.

Abstract
RATIONALE Melanotic neuroectodermal tumor of infancy (MNTI) is a rare tumor originated from neural crest cells with the potential for recurrence and metastasis. The peak age for the disease is during the first year after birth. The current therapy is primarily surgery. The patient reported here is the first case of MNTI treated with metformin. PATIENT CONCERNS A case of a 4-month-old infant with a history of swelling in the mouth for 1 month. DIAGNOSIS The tumor was diagnosed using radiology, pathology, and immunohistochemistry, and it was performed with complete surgical resection. Unfortunately, the tumor recurred 3 months after surgery. INTERVENTIONS We prescribed metformin for the infant. OUTCOMES Currently, after 9 months of treatment, the tumor is well controlled without apparent side effects. LESSONS The case presented suggested that metformin may be an underlying therapy for MNTI.

Abstract
BACKGROUND The aim of this study was to integrate the available data published on radiation-induced sarcoma of the oral cavity into an analysis of its clinical features, treatment modalities and prognostic factors. METHODS An electronic search was undertaken in September 2019. The eligibility criteria included publications that had enough clinical and histological information to confirm the diagnosis. RESULTS Forty-two publications with 122 radiation-induced sarcoma of the oral cavities (RISOCs) were included. The mean latency period was 114 months and mean radiation total dose was 62.5 Gy. The tumors were more prevalent in males between 50 and 60 years old and the mandible was the most affected site. Osteosarcoma was the most prevalent histological type and patients were mostly treated with radical surgery. CONCLUSIONS RISOC showed a poor survival rate of 15.1% in 5-year follow-up. Gender and histological type were independently associated with survival.

The aim of this study was to integrate the available data published on Liposarcomas (LPSs) of the oral cavity into an analysis of its clinical features, treatment modalities, and prognostic factors. An electronic search was undertaken in January 2019. The eligibility criteria included publications that had enough clinical and histological information to confirm the diagnosis. Forty-five publications (104 LPSs) were included. The lesion was more prevalent in males from the fifth to seventh decades of life. Treatment (P = .03) and distant metastasis (P = .0001) were independently associated with survival. A lower possibility of recurrence was statistically associated with age (younger patients) (P = .03), tumor size (smaller than 2.8 cm) (P = .001), and treatment (radical surgery) (P = .04). LPS presents a good survival for patients after 5 years of follow-up (66.4%). Patients who were treated with conservative surgery and presented with distant metastasis showed poor prognosis.

Abstract
Gingival lesions rarely occur in newborns. However, when present, they commonly worry the parents and impair the infant's feeding, thus affecting growth. Such lesions are usually nonneoplastic in nature, although malignancies may develop; therefore, specimens must be submitted for histopathologic examination. A 2-month-old girl presented with a 10-mm nodule on the anterior lower alveolar ridge in association with natal tooth extraction and neonatal tooth eruption. The lesion was excised with high-power laser under local anesthesia, and a histopathologic diagnosis of a peripheral ossifying fibroma was made. In addition to peripheral ossifying fibromas being rare in newborns, the use of high-power lasers for surgical procedures in newborns have been proven to be safe, comfortable, and efficient.
