An unusual cause of inability to flex the interphalangeal joint of the thumb in a patient with von Recklinghausen's disease is reported. A tumor in the cubital fossa and the basic characteristics of this disease led to a preoperative misdiagnosis of anterior interosseous nerve paralysis. However, surgical exploration and histological examination showed that the correct diagnosis was rupture of the flexor pollicis longus tendon caused by intratendinous proliferation of a neurofibroma. This is the first report in the English-language literature of a flexor tendon rupture caused by intratendinous tumor proliferation.
报告了1例患有冯雷克林霍增氏病（神经纤维瘤病）的患者，其拇指指间关节无法屈曲的罕见病因。肘窝处的肿瘤以及该疾病的基本特征导致术前误诊为骨间前神经麻痹。然而，手术探查和组织学检查显示，正确诊断为神经纤维瘤腱内增生导致拇长屈肌腱断裂。这是英文文献中关于腱内肿瘤增生导致屈肌腱断裂的首例报告。
