Abstract
Background and clinical significance: Phyllodes tumors (PTs) are rare stromal neoplasms originating in the connective tissue of the breast, distinct from carcinomas that arise from the ducts or lobules. These tumors exhibit a broad spectrum of morphologic features and are traditionally classified as benign, borderline, or malignant. Case presentation: We present the case of a 71-year-old female diagnosed with a malignant PT and treated at our hospital. The patient noticed a gradually enlarging lump in her right breast over several months. Mammography was inconclusive, but an ultrasound later revealed a lobulated, firm mass, classified as BIRADS 5. Physical examination identified a 20 cm mass, and core needle biopsy suggested a borderline PT. Following lumpectomy, pathology confirmed a malignant tumor with narrow surgical margins (0.1 cm). Although mastectomy was recommended to achieve wider margins, the patient opted for adjuvant radiotherapy. She received 50 Gy in 25 fractions to the whole breast, followed by a 16 Gy boost to the tumor bed in 8 fractions. The treatment was well tolerated and completed successfully. Initially, the patient’s therapeutic management was delayed due to a combination of personal and organizational factors. However, the process was later streamlined through the use of a novel digital tool developed to facilitate the entire patient journey within our hospital system. Conclusions: This case highlights the diagnostic complexities of PTs, the critical need for effective collaboration between specialties, and the importance of timely treatment planning for optimal patient outcomes.
