When observed grossly in the peritoneal cavity, an accessory spleen may appear as one or more dark red to black nodules that have a smooth surface and range from less than a millimeter to several millimeters in diameter. These small nodules of splenic tissue have been observed in the mesenteric attachment of the spleen ( Figure 1 , arrowhead), pancreas, and elsewhere in the abdominal cavity. Histologically, accessory spleens may have all or some splenic components, such as the capsule, trabeculae, red pulp, and/or white pulp ( Figure 2 ). ## 英文原文 · Recommendation Accessory spleen should be diagnosed but not graded. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0409.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0418.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
