AB  - Spindle cell lipomas (SCLs) containing minimal fat are rare and can be 
      diagnostically challenging due to their similar radiographic appearance to other 
      benign and malignant tumours. SCLs are benign lipomatous tumours that typically 
      occur in middle aged to elderly men as slow-growing, painless masses in the 
      subcutaneous tissue of the posterior neck, shoulders or back. However, rarely 
      these tumours can arise in unusual locations such as the lower extremities. We 
      present an unusual case of a lipid poor SCL occurring in the lower extremity. 
      Initial clinical and radiographic findings were suspicious for a malignancy. Two 
      core biopsies demonstrated benign fibro collagenous tissue, so a marginal 
      excision was performed. Final histopathological and immunohistochemical stains 
      confirmed the diagnosis of an SCL. Radiologists, pathologists and oncologic 
      surgeons should be aware of this lipomatous tumour's potential to present in 
      unusual locations with minimal fatty components to increase confidence in 
      radiologic-pathological concordance.
