Neurofibromas are frequently present in the skin, but are uncommon in the oral and maxillofacial region. There are three histological variants of neurofibroma: localized, diffuse, and plexiform. The plexiform histological variant of neurofibroma is the least common and is a rare occurrence in the oral cavity. Furthermore, plexiform neurofibroma is usually pathognomonic of neurofibromatosis type 1. A case of solitary plexiform neurofibroma of the tongue with no evidence of neurofibromatosis in a 50-year-old female Chinese patient is reported here. The lesion presented as a single, large, well-circumscribed rounded mass in the left hemi-tongue. The tumour was completely excised. No recurrence was observed at the 6-month follow-up.

Background: Peripheral nerve sheath tumors (PNSTs) encompass entities with different cellular differentiation and degrees of malignancy. Spatial heterogeneity complicates diagnosis and grading of PNSTs in some cases. In malignant PNST (MPNST) for example, single cell sequencing data has shown dissimilar differentiation states of tumor cells.

NF1 encodes the multifunctional tumour suppressor protein, neurofibromin, which is best known for its causative role in Neurofibromatosis type 1 and in regulating MAPK signaling. Neurofibromin, in a context-specific manner, is involved in various tumorigenic processes, including those in melanocytes. This study investigated whether NF1 loss can collaborate with oncogenic GNAQ to promote melanoma in the dermis or eyes, where the G alpha q pathway is almost always activated.

Background: Plexiform neurofibromas (PNs) are histologically benign peripheral nerve sheath tumors associated with neurofibromatosis type 1 (NF1) and often lead to significant morbidity due to growth. Management includes watchful waiting, surgery for partial debulking, and, since recently, systemic treatment with MEK inhibitors. However, due to the scarcity of natural history studies, our understanding of the natural progression of PNs to guide clinicians in deciding in whom and when to intervene is scarce.

The MEK inhibitor selumetinib induces objective responses and provides clinical benefit in children with neurofibromatosis type 1 (NF1) and inoperable plexiform neurofibromas (PNs). To evaluate whether similar outcomes were possible in adult patients, in whom PN growth is generally slower than in pediatric patients, we conducted an open-label phase 2 study of selumetinib in adults with NF1 PNs. The study was designed to evaluate objective response rate (primary objective), tumor volumetric responses, patient-reported outcomes and pharmacodynamic effects in PN biopsies.

Objective: In Japan, selumetinib is used in pediatric patients with neurofibromatosis type 1 (NF1) and symptomatic inoperable plexiform neurofibroma (PN). However, there have been no real-world reports on Japanese patients. In this study, we reported a single-center, short-term experience with selumetinib after its approval in Japan.
