Nodular fasciitis is a benign tumor, resulting from reactive proliferation composed of fibroblastic/myofibroblastic cells. Due to its rapid growth and high cellularity it may be mistaken for sarcoma. Despite the possibility of spontaneous regression, excision is the treatment of choice. A 24-year-old female patient presented with a nodule on the zygomatic region with 3 months of evolution. Excisional biopsy was performed. Histopathological examination associated with immunohistochemical markers HHF35, AML and Ki-67 allowed diagnostic confirmation. The main relevance of the case presented is its rare location, suggesting its inclusion among the differential diagnoses of tumor lesions on the face.

Fibromatosis-like metaplastic carcinoma (FLMC) is a rare subtype of metaplastic carcinoma of the breast. Diagnosing this entity poses significant challenges, particularly in core biopsies due to limited sampling and overlap with benign spindle cell lesions such as nodular fasciitis and fibromatosis. We present an example of FLMC in an asymptomatic middle-aged woman.

Nodular fasciitis is a benign, usually self-limiting myofibroblastic proliferation with a predilection for the upper extremities, trunk, and head and neck, and almost all of which harbor the fusion. Since nodular fasciitis is not widely recognized to arise within the joints, it may therefore cause diagnostic confusion in this uncommon setting. We report an unusual tumor of an 11-year-old patient who presented with a 6-month history of right elbow swelling and pain.

Fibromyxoid aSoft Tissue Tumor With PLAG1 Fusion-The First Case in an Adult Patient.

Genes Chromosomes Cancer

November 2024

Department of Pathology and Molecular Medicine, Second Faculty of Medicine, Charles University and Motol University Hospital, Prague, Czech Republic.

With the expanding possibilities of human genome research in recent years, the number of cases of soft tissue tumors that we are able to classify into the correct subgroups and to reveal their molecular profile is increasing. Among such tumors, we can also consider neoplasms that have a specific fusion of genes, in our case namely the pleomorphic adenoma gene 1 (PLAG1) and its partner. PLAG1 gene fusions were previously associated mainly with salivary gland pleomorphic adenomas, lipoblastomas, myoepithelial tumors, uterine epitheloid, myxoid leiomyosarcomas, and, recently, with PLAG1-rearranged fibromyxoid soft tissue tumors.

Clinicopathological Characteristics and Favorable Prognosis of Pediatric Cutaneous Nodular Fasciitis: A Case Series.

Clin Exp Dermatol

November 2024

Department of Dermatology, Beijing Children's Hospital, Capital Medical University, National Center for Children's Health, Beijing, China.

Article Synopsis
  • - Cutaneous nodular fasciitis (cNF) is a rare, non-cancerous growth that can be mistaken for cancer due to its rapid development and similar appearance under a microscope.
  • - A study of 15 pediatric cNF cases found that most occurred in kids around 6 years old, primarily on the head and neck, and revealed specific genetic changes (like the MYH9-USP6 fusion) in many samples.
  • - The research emphasizes the benign nature of cNF, highlighting that most cases can resolve on their own without surgery and stresses the importance of proper diagnosis to prevent unnecessary treatments, especially in areas that are cosmetically sensitive.
