Background: Rhabdomyosarcoma (RMS), a rare malignant tumor, frequently affects pediatric patients, with 35%-40% occurring in the head and neck. This study analyzes the clinicopathologic profile of pediatric head and neck rhabdomyosarcomas from Brazil, Guatemala, Mexico, and South Africa.
Methods: We reviewed 44 cases from 10 Oral and Maxillofacial Pathology services, conducting immunohistochemical analyses of desmin, myogenin, Myo-D1, and Ki67, with quantification via QuPath software.
Background: Aspergillosis is a fungal disease caused by the inhalation of fungal spores of the genus spp. This fungus mainly affects the lungs but can spread and infect the maxillofacial region through the bloodstream or inoculation of the fungus after extraction or endodontic treatment, especially in the upper posterior teeth. The disease has nonspecific clinical manifestations that hinder its early diagnosis.

Microscopically, a proliferation of bland spindle cells interspersed with collagen fibers and prominent staghorn-like blood vessels was observed. Immunohistochemical analysis revealed strong positivity for CD34, Bcl-2, CD99, and STAT-6, confirming the diagnosis of Solitary Fibrous Tumor (SFT).

Materials And Methods: Clinical data from 3 patients diagnosed with STK were obtained from the archives of the Laboratory of Oral Pathology at the Federal University of Rio de Janeiro- Brazil from 2020 to 2023. Two oral pathologists reviewed conventional hematoxylin and eosin-stained slides of each case.
Article Synopsis
- The study analyzes the characteristics of oral reactions to injectable soft tissue fillers, focusing on 151 patients, predominantly females averaging 54.9 years old.
- Most reactions occurred about 20.4 months after injection, often presenting as painless nodules in the lips, with silicone and polymethylmetacrylate being the most common fillers used.
- Key findings showed differences in reaction patterns based on the type of filler and highlighted the importance for clinicians to recognize these potential reactions when assessing asymptomatic nodules in older female patients.
