A bizarre parosteal osteochondromatous proliferation (BPOP) is a rare, benign, osseous tumor that presents as an exophytic cortical growth consisting of bone, cartilage, and fibrous tissue. However, the identification of BPOP by preoperative imaging along with appropriate diagnosis and treatment without recurrence is challenging, particularly for BPOPs that rarely develop in certain parts of the body. Herein, we report a rare case involving a BPOP at the sesamoid bone of the hallux that was first suspected on preoperative computed tomography imaging. There has been no recurrence 3 years after surgical resection.
怪异型骨旁骨软骨瘤样增生（BPOP）是一种罕见的良性骨肿瘤，表现为一种由骨、软骨和纤维组织构成的外生性皮质生长。然而，通过术前影像学检查来识别BPOP，并进行恰当诊断和治疗且不复发具有挑战性，尤其是对于在身体某些部位很少发生的BPOP。在此，我们报告一例罕见病例，该病例涉及拇趾籽骨处的BPOP，术前计算机断层扫描成像首次怀疑为此病。手术切除3年后未出现复发。
