Mammary DTF originates from fibroblasts and myofibroblasts within the breast tissue, representing 0.2% of all breast tumors. This study aims to present and discuss the clinical presentation and management of seven cases of breast DTF. Methods This single-center case series was conducted at the breast clinic of Smart Health Tower in Sulaymaniyah, Iraq. It included all patients diagnosed as breast DTF by histopathological examination, with those lacking complete data excluded. The patients were treated and managed between January 2021 and August 2024. Results This study involved seven female patients with a mean age of 35.29 ± 14.29 years. Clinically, six of them (85.71%) presented with a non-tender palpable breast mass, while one patient (14.28%) reported breast pain. Ultrasound revealed hypoechoic lesions in all cases. The average size of the masses was 29.43 ± 17.26 mm. All patients underwent wide local excision of the breast mass. Histopathological examination confirmed the diagnosis of DTF in all cases. Conclusion Diagnosing a desmoid tumor of the breast can be difficult, as it can mimic breast carcinoma. The Wide local excision is often the preferred treatment to prevent future recurrences.
