Background Diagnosis of fibrous tumors can be challenging and expensive due to the use of special stains. Objective Determine the usefulness of fluorescence microscopy in the evaluation of elastic pattern on H&E stained slides. Methods A total of 228 slides were evaluated by fluorescence microscopy for elastic tissue patterns and sensitivity and specificity determined for relevant comparisons. Results Fluorescence microscopy was found to be useful especially in the case of distinguishing dermatofibroma (DF) vs dermatofibrosarcoma protuberans (DFSP) and also dermatomyofibroma (DMF) vs other fibrous tumors. Limitations In some cases, excessive background staining made it difficult to interpret. Conclusion Evaluation of elastic tissue patterns by fluorescence microscopy in fibrous tumors is a cheap and efficient means to further delineate these often challenging tumors.
