Collagenous fibroma (desmoplastic fibroblastoma) is a recently described rare benign tumor. Since this tumor was characterized by Evans in 1995, fewer than 100 cases have been reported in English literature with the largest series published by Miettinen and Fetsch. Preoperative radiological diagnosis is important to avoid over-treatment and unnecessary extensive procedures, but is difficult because diagnostic imaging findings for collagenous fibroma have not been established. Here we report the US and MRI appearance of a lesion localized deep under the deltoid muscle in a 34-year-old woman with a palpable painless mass. Histological findings were consistent with a collagenous fibroma. As far as we know, this is the first description of US appearance of a collagenous fibroma in English literature.

Desmoplastic fibroma (DF) is an uncommon benign bone tumor that typically affects the facial bones, with cerebral cranium involvement being extremely rare. We report a unique case of DF in the parietal bone of a 28-year-old woman, notable for its rapid growth during pregnancy-a phenomenon not previously documented. The imaging features of this case also differ from all but one previously reported case.

Objectives: Microvascular free tissue transfer (MVFTT) for head and neck reconstruction is infrequently performed in pediatric patients. There is a paucity of data on perioperative airway management in pediatric MVFTT, such as the need for tracheostomy, which can pose higher morbidity to young patients due to potential long-term effects on the softer, more pliable laryngotracheal cartilage. Our objective was to report airway outcomes on pediatric patients undergoing MVFTT after segmental mandibulectomy with or without tracheostomy.

Background/aim: Desmoplastic fibroblastoma, also known as collagenous fibroma, is a rare benign mesenchymal neoplasm that primarily arises in the subcutaneous tissue of upper extremities and limb girdles. The knee is an uncommon location for desmoplastic fibroblastoma. Recent studies have demonstrated the presence of immunoreactivity for FOS like 1 (FOSL1) and rearrangements of FOSL1.

Article Synopsis
- The study aims to compile and summarize information about desmoplastic fibroma in the jaw bones, focusing on its key characteristics.
- A systematic review identified 66 articles detailing 96 cases, revealing a higher prevalence in females and younger patients, particularly affecting the mandible, with painless swelling as the primary symptom.
- Surgical removal is the standard treatment with a recurrence rate of 10.8%, and histopathological analysis shows specific cellular and molecular features that require more research for understanding the tumor's development.
