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.

Median mandibular cyst is defined as an odontogenic cyst in a rare midline location. In spite of this definition, there have been two reports of a peculiar lesion, so-called "ciliated" median mandibular cyst associated with vital teeth, the origin of which cannot be explained in terms of odontogenic epithelium multipotentiality. We describe a thorough profile of an additional example.

Background: While early intervention in psychosis (EIP) programs have been increasingly implemented across the globe, many initiatives from Africa, Asia and Latin America are not widely known. The aims of the current review are (a) to describe population-based and small-scale, single-site EIP programs in Africa, Asia and Latin America, (b) to examine the variability between programs located in low-and-middle income (LMIC) and high-income countries in similar regions and (c) to outline some of the challenges and provide recommendations to overcome existing obstacles.
Methods: EIP programs in Africa, Asia and Latin America were identified through experts from the different target regions.

Malignant mesenchymal tumors are a diverse group of aggressive cancers originating from mesenchymal cells in connective tissues such as bone, muscle, cartilage, and fat. These tumors often invade surrounding tissues and metastasize to distant organs, posing significant treatment challenges. Among them, malignant mesenchymal tumors located in the distal femur are particularly rare, with limited reports detailing effective surgical and functional reconstruction strategies following wide resection.

The cratonic crust contains abundant mineral deposits of metals such as gold, copper and rare earths and is underlain by a thick mantle lithosphere rich in the volatiles carbon, sulfur and water. Although volatiles are known to be key components in metallogenesis, how and where they are distributed in the cratonic lithosphere mantle and their role in the initial enrichment of metals have not been sufficiently explored. Here we compile sulfur and copper contents of global cratonic peridotites, identifying sulfide-rich and copper-rich continental roots at depths of 160-190 km at cratonic margins.
