Small cell osteosarcoma in gnathic bones in the maxilla: case report in a pediatric patient.

Small cell osteosarcoma (SCOS) is a rare variant of conventional osteosarcoma, characterized by tumor cells of small size and uniform morphology, which can lead to diagnostic confusion with other small cell tumors, requiring a detailed diagnostic approach. The manifestation in a child adds a degree of complexity, as the management of malignant tumours in paediatric patients requires specific considerations to minimize the long-term side effects of oncological treatment and preserve the structural and functional development of the orofacial region. This report concerns an 8-year-old female patient referred to the Oral and Maxillofacial Surgery outpatient clinic with progressive swelling in the right maxillofacial region, initially asymptomatic, but progressing to pain and difficulty chewing.

Preparation of -Myrcene-Chitosan Nanoparticles and Their Uptake and Toxicity in Larvae.
