Pseudomalignant osseous tumor of soft tissues is a rare tumor of the hand. Histopathologic differentiation of this benign lesion from malignant lesions is difficult because mitotic figures are common in typical cases, but bizarre pleomorphic and hyperchromatic nuclei never occur. Wide excision is adequate in most cases, but ray resection is indicated when this benign lesion recurs after wide excision, invades the vital structures, or causes severe functional impairment. Review of the literature revealed 15 cases of this lesion in the digits of the hand, including our case. Of these 15 cases, misdiagnosis of malignancy in three cases and loss of function in an additional four cases led to ray resection.
软组织假恶性骨肿瘤是一种罕见的手部肿瘤。由于在典型病例中常见有丝分裂象，但奇异的多形性和深染核从未出现，所以将这种良性病变与恶性病变进行组织病理学鉴别很困难。大多数情况下广泛切除就足够了，但当这种良性病变在广泛切除后复发、侵犯重要结构或导致严重功能障碍时，则需行射线切除。文献回顾显示，包括我们的病例在内，手部手指有15例这种病变。在这15例中，3例被误诊为恶性，另外4例因功能丧失而行射线切除。
