Results: 117 cases were retrieved, all women, with a median age of 53 years. Of these, 101 pairs of CB/resection specimens were obtained. CB diagnosis was RS without atypia in 79 cases, RS with atypia in 19 cases and RS with in situ carcinoma in 3 cases. After excision, 21/79 (26,6 %) cases diagnosed as RS without atypia were upgraded: 17 to atypia, 3 to in situ carcinoma and 1 to invasive carcinoma. Of those cases diagnosed on CB as RS with atypia, 9/19 (47, 4 %) were upgraded: 8 to in situ carcinoma and 1 to invasive carcinoma. Conclusion: Our results support the excision of all lesions diagnosed on biopsy as RS. *FM and MC are joint first authors.
