Overview
Diagnostic study of choice
- Biopsy is the most important and conclusive diagnostic procedure for desmoid tumor
- After biopsy, electron microscopy is performed to obtain further clarity and confirmation for the diagnosis
- Spindle cells of desmoid tumors appear to be myofibroblasts on electron microscopy which represents an abnormal proliferation of myofibroblasts, which normally disappear gradually during the later stages of wound healing
- Immunohistochemical stains are done to look for nuclear accumulation of beta-catenin
- Regardless of the site, 90% of desmoids show nuclear reactivity (has relatively high specificity)
