Objectives: The objectives of this study were to review our experience with pediatric melanoma of the head and neck and discuss proper diagnostic protocols and suggest a possible treatment algorithm.
Study Design: The authors conducted a retrospective chart review of patients under the age of 18 who underwent treatment for melanoma of the head and neck at a tertiary care university hospital.
Results: Six patients were identified in the last 25 years at our institution. Four patients had melanomas in the auricle, one in the cheek, and one in the forehead. All occurrences identified presented in the past 7 years. All were treated with wide local excision. Three patients received sentinel lymph node biopsy, one received a neck dissection after identification of positive sentinel nodes, and two patients received postoperative interferon therapy. No surgical complications were reported. At the time of this submission, no patients were found to have recurrence of the disease.
Conclusions: Pediatric melanoma of the head and neck may be managed effectively using current techniques used in treating adult patients. The use of sentinel lymph node biopsy is recommended when the depth of invasion cannot be determined from original biopsy, the original pathologic diagnosis is ambiguous, or depth of invasion from biopsy is sufficient to warrant its use. In addition, the use of adjuvant interferon alpha-2b is recommended in patients at high risk for recurrence.

: With the rise in prevalence of diagnostic genetic techniques like RNA sequencing and whole exome sequencing (WES), as well as biological treatment regiments for cancer therapy, several genes have been implicated in carcinogenesis. This review aims to update our understanding of the Neurofibromatosis 2 (NF2) gene and its role in the pathogenesis of various cancers. : A comprehensive search of five online databases yielded 43 studies that highlighted the effect of sporadic NF2 mutations on several cancers, including sporadic meningioma, ependymoma, schwannoma, mesothelioma, breast cancer, hepatocellular carcinoma, prostate cancer, glioblastoma, thyroid cancer, and melanoma.

The discovery of tumor-derived neoantigens which elicit an immune response through major histocompatibility complex (MHC-I/II) binding has led to significant advancements in immunotherapy. While many neoantigens have been discovered through the identification of non-synonymous mutations, the rate of these is low in some cancers, including head and neck squamous cell carcinoma. Therefore, the identification of neoantigens through additional means, such as aberrant splicing, is necessary.

Background: Sinonasal mucosal melanoma has poor survival despite multimodality treatment. While the impact of immunotherapy (IT) on metastatic cutaneous melanoma is well-defined, there are relatively little data on sinonasal mucosal melanoma.
Objective: We sought to define immunotherapy outcomes in patients with sinonasal mucosal melanoma.

Background And Objectives: Since the publication of the German Cooperative Oncology Group Selective Lymphadenectomy Trial and Multicenter Selective Lymphadenectomy Trial II (MSLT2) trials, the treatment paradigm for node-positive melanoma has shifted from completion lymph node dissection (LND) to nodal ultrasound surveillance. We sought to identify the impact of this practice change on postoperative outcomes in a national cohort.
Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients diagnosed with truncal/extremity malignant melanoma who underwent axillary/inguinal LND.
