Abstract
MethodsA systematic search on Google Scholar was conducted for English-language studies on breast carcinoma within fibroadenomas. Studies on fibroadenomas with no malignant components, review articles, pre-prints, incomplete data, and those published in suspicious journals were excluded.ResultsOn ultrasonography, 28 masses (36.8%) appeared benign, and 20 (26.3%) were suspicious, with ultrasonographic data unavailable for the remaining tumors (36.8%). Mammography data were available for 50 tumors, revealing 27 benign lesions (54%) and 23 suspicious lesions (46%).
Among the 17 lesions with available magnetic resonance imaging data, five were benign lesions (29.4%), and 12 were suspicious (70.6%). Cytology evaluation among 46 tumors revealed that 20 (43.5%) were benign, 24 (52.2%) were malignant, and two (4.3%) were suspicious. The most commonly performed surgery was wide local excision (50.7%), followed by mastectomy (32.9%).
On histopathology, 11 tumors exhibited more than one pathology. Ductal carcinoma in situ was the most frequent finding (40.8%), followed by invasive ductal carcinoma (28.9%) and lobular carcinoma in situ (28.4%). Recurrence was observed in one case (1.4%), and metastasis occurred in two cases (2.8%).ConclusionAlthough rare, carcinomas arising within fibroadenomas may present considerable challenges in preoperative diagnosis, whether through imaging or cytology.
Therefore, clinicians may find it necessary to approach fibroadenomas with increased caution.
