Fibromatosis of the breast; another diagnosis of cancer like lesions: About 4 cases reports

Summary

Introduction and importance: Desmoid fibromatosis is a benign monoclonal fibroblastic tumor that was first reported in 1832 and arises from musculoaponeurotic structures. It is an uncommon tumor that can mimic breast carcinoma in both hits clinical and radiological presentation. This entity mainly affects patients in their fourth and fifth decades of life. Case presentation: Our four patients were of young women in their 2nd and 3rd decade that consulted for masses of the breast. These lesions were suspicious for malignancy in both their clinical and radiological features despite not having any family history of breast carcinoma. Clinical discussion: Only histology provides the diagnosis, it is locally invasive, non-metastatic but with a high potential of recurrence and the sole treatment is complete and wide local excision with clear margins. Conclusion: Although it is a rare clinical scenario, the presence of an unusual breast or chest wall tumor such as a desmoid tumor should be considered when obvious breast changes and history do not correlate with routine diagnostic measures.
