title: Recurrent bilateral mammary fibromatosis (desmoid tumor) imaged with technetium-99m pentavalent dimercaptosuccinic acid [99mTc-(V)DMSA] scintimammography.
abstract: BACKGROUND
  Breast fibromatosis is a rare, benign, recurring, locally destructive entity.
  
  
  METHODS
  A 35-year-old woman underwent right-sided lumpectomy, revealing fibromatosis with epithelial hyperplasia. Two years later, she was re-evaluated due to a three times as large mass recurrence on X-ray mammography. (99m)Tc-(V)DMSA scintimammography revealed diffuse increased radiotracer uptake occupying the entire breast. A less widespread similar uptake was observed in the contralateral breast. Mammography did identify neither the posterior margins of the mass nor the left-sided lesion. The patient underwent mastectomy and left-sided open biopsy, revealing bilateral fibromatosis. Ki-67 expression was moderate.
  
  
  CONCLUSIONS
  (99m)Tc-(V)DMSA scintimammography can provide information regarding the nature of the lesion, its extent and bilateral involvement (especially in dense breasts) and could prove useful as a predictor of its potential for recurrence.
