Corrigendum to "European guidelines for the diagnosis, treatment and follow-up of breast lesions with uncertain malignant potential (B3 lesions) developed jointly by EUSOMA, EUSOBI, ESP (BWG) and ESSO" [Eur J Surg Oncol 50 (1) (January 2024) 107292]

The authors would like to point out the following corrections to Figs. 5 and 7 within the article. The legend for Fig. 5 should be:[Formula presented] The citation of Fig. 5 within the text should also be removed from its current position in the first sentence in the following paragraph on Page 5 and appear as follows: The classic lobular neoplasia cells are of either type A (small uniform nuclei with inconspicuous nucleoli and scanty cytoplasm) (Fig. 4) or type B (larger nuclei with more conspicuous nucleoli and moderate cytoplasm); neither is high-grade. Florid LCIS comprises a proliferation of type A or type B classic LCIS cells involving large acini or ducts (>40− 50 cells in largest diameter of an acinus and/or minimal intervening stroma between acini) [2,28].The lesion in its pure form on core biopsy is categorized as either B4 (UK) or B5a. PLCIS is diagnosed when the lesion comprises high-grade nuclei and is categorized as B5a. Classical LCIS can be associated with luminal calcification and comedo-necrosis and hence identified mammographically. Calcification is even more likely with PLCIS and florid LCIS. While classic LCIS is strongly and uniformly positive for ER and negative for HER2, PLCIS can be ER-negative and HER2-positive, a feature that can help distinguishing both lesions in difficult cases [32–34] (Fig. 5). FEA is characterized by low-grade (monomorphic) cytological atypia with one to several layers of mildly atypical cuboid to columnar cells in a flat architecture. Nuclei are round and uniform with inconspicuous nucleoli, similar to the nuclei that characterize low-grade DCIS, resembling the monomorphic cytological atypia of low-grade DCIS [17]. FEA is often associated with intraluminal secretions and calcifications in dilated TDLU (Fig. 7). Fig. 7 is incorrect and should appear as per the below image.[Formula presented] The authors would like to apologise for any inconvenience caused.
