The object of this presentation is to discuss the characteristics of a few primary bone tumors (osteochondroma versus chondrosarcoma), as presented in the literature, in relation to a specific lesion that the authors encountered. The specific lesion, an unusual osteochondroma arising from the plantar aspect of the first metatarsal, had a few characteristics of its own that are presented. This case report includes the pertinent history and clinical findings of the lesion with associated radiographic laboratory and pathology results that are very essential in determining an accurate differential diagnosis. The surgical discussion and postoperative care is important in discussing the particular characteristics of this tumor and the pattern of its regrowth. Recurrence of a lesion of this type is very rare and, when it does occur, must undergo much scrutiny. This regrowth is the most perplexing characteristic of this tumor and the reason for the lengthy presentation. The final diagnosis remained osteochondroma with benign postoperative ectopic bone formation. It is the authors' opinion that this is a very atypical lesion in the study of bone tumors and is a worthwhile presentation to the literature as such.
本报告的目的是讨论文献中呈现的一些原发性骨肿瘤（骨软骨瘤与软骨肉瘤）的特征，并结合作者遇到的一个特定病变进行探讨。这个特定病变是一个起源于第一跖骨足底侧的不寻常骨软骨瘤，它有自身的一些特征。本病例报告包括该病变的相关病史、临床发现以及相关的影像学、实验室和病理结果，这些对于准确的鉴别诊断至关重要。手术讨论和术后护理对于探讨该肿瘤的特殊特征及其复发模式很重要。这种类型病变的复发非常罕见，一旦发生，必须进行详细检查。这种复发是该肿瘤最令人困惑的特征，也是进行冗长报告的原因。最终诊断为骨软骨瘤伴良性术后异位骨形成。作者认为，在骨肿瘤研究中这是一个非常不典型的病变，因此值得在文献中进行报告。
