Histological findings of GBMTs with ss invasion. a, A GBMT was observed by EUS. The LHEL was thickened (arrows). b, Histological image of the specimen. The ss seemed edematous and was thickened (bar). c, Slight ss invasion was observed (arrowhead). Tumor invasion at the mp can be observed at both ends, with the tumor dividing the mp (arrows). d, A thickened LHEL was also observed in this specimen. e, The ss became thickened, as shown in Fig. 4b (bar). A GBMT with ss invasion was observed (arrowhead). f, The GBMT invaded the ss across the mp (arrowheads: ss invasion, arrows: mp). ss, subserosa; GBMT, gallbladder malignant tumor; EUS, endoscopic ultrasonography; LHEL, lateral hyperechoic layer; mp, muscularis propria
