Objective: The main objective of this study was to determine the distribution of fibroadenoma according to tumor size and women age, to define the share of fibroadenoma in total number of breast punctures and to determine the frequency of fibroadenoma in the left and right breast. Materials and methods: The study included 1135 samples of breast nodules punctured at the Department of Radiology and 11 breast nodules punctured at the outpatient department of the Department of Clinical Cytology KBC Split, from January 1, 2020 to December 31, 2020. Data on the results of cytological analysis of puncture nodes in the breast were obtained by inspecting medical records (computer database KBC Split). Results: Out of 1135 samples of breast nodules punctured at the Department of Radiology and 11 nodules punctured at the outpatient department of the Department of Clinical Cytology KBC Split, 85 punctured nodules were diagnosed as fibroadenoma, which represents a share of 7.41%. The highest incidence was in women in the age group of 40 to 50 years, while only two women (2,4%) diagnosed with fibroadenoma were older than 50. Fibroadenoma was more prevalent in the right breast - 48 women (56.5%) and in 37 (43.5%) women in the left breast, respectively. The largest number of patients, 35 of them (41.52%) had a tumor smaller than 11 mm, while in only one woman (1.2%) exceeded 40 mm. It was found that there was no relationship between women’s age and tumor size as well as presentation in the left or right breast. Conclusion: Cytology plays a significant role in the diagnosis of fibroadenoma. FNA cytology is a quick, simple and not so aggressive and painful method. Once the cytological diagnosis is established radiological follow up is recommended. If markedly increased or with cytological signs of atypia, surgery is recommended.
