title: [Value of fine needle aspiration cytology in the diagnosis and management of fibroadenoma of the breast].
abstract: Cytological and histopathological biopsies were obtained from 121 breast lumps clinically diagnosed as fibroadenomas. Of these 98.3 percent of the lesions were benign. The cytological diagnosis was benign in 95.1 percent of 101 (83.4% of total) cases confirmed as fibroadenomas, histopathologically, but inadequate for diagnosis in 4.9 percent. The remaining 20 lesions included one breast cancer and one primary malignant lymphoma. In this group aspiration cytology was inadequate for diagnosis in 20 percent of the cases (P < 0.05). The cytological reports cast suspicion in the two malignant cases. No lesion with benign cytology was subsequently shown to be malignant. Ninety-five (78.5%) cases of the lesions, representing 72 women under 35 years of age, which has been clinically diagnosed as fibroadenomas, showed fibroadenoma, histopathologically, in 89.5% of these cases. The other 26 (21.5%) lesions in 21 patients, who were over 35 years in age, had 61.5 percent fibroadenomas, cytological results cast suspicion of fibroadenoma in 87.1 percent of these cases. The other 16 histopathologically diagnosed fibroadenomas in patients over 35 years of age showed 62.5% were cytologically suspected of being fibroadenomas (P < 0.025). As a result of this study it is reasonable to suggest that a typical clinical fibroadenoma can be treated conservatively in women under 35 years, but only if an adequate cytological smear obtained by fine needle aspiration does not show malignant of suspicious cells.
