Một quang phổ rộng của khối ung thư và các tổn thương có thể xảy ra tumorlike trong tay và cổ tay, mặc dù với tần số ít hơn đôi chút trong phần khác của cơ thể. Một sự hiểu biết kỹ lưỡng của các chẩn đoán phân biệt của các thương tổn luận án và một chiến lược toàn diện để đánh giá là trung tâm chăm sóc hiệu quả. | Tumorlike Lesions and Benign Tumors of the Hand and Wrist Ann-Marie Plate MD Steven J. Lee MD German Steiner MD and Martin A. Posner MD Abstract A broad spectrum of tumorlike lesions and neoplasms can occur in the hand and wrist although with somewhat less frequency than in other parts of the body. A thorough understanding of the differential diagnosis of these lesions and a comprehensive strategy for evaluation are central for effective care. Plain radiographs are diagnostic for most bony lesions whereas magnetic resonance imaging may be necessary to help differentiate a benign soft-tissue lesion from the rare malignant neoplasm. In spite of the complex anatomy adherence to proper oncologic principles most often will lead to a satisfactory outcome. J Am Acad Orthop Surg 2003 11 129-141 Lesions of the hand and wrist may originate in either soft tissues or bone. They can be divided into two groups tumorlike lesions and true neoplasms with the latter subdivided into benign and malignant tumors. Although there are a relatively large number of lesions and subtle variations established principles of tumor management provide a logical and systematic approach to both diagnosis and treatment. Collaboration with a musculoskeletal radiologist and a pathologist is frequently important for arriving at the correct diagnosis and applying the proper treatment. Although many of these lesions can occur in other parts of the body their presentation and treatment may differ in the hand and wrist. Classification Benign neoplasms have been clinically classified into three types latent active and locally aggres-sive.1 Latent tumors either remain unchanged or heal spontaneously and therefore may not require treat ment other than observation. An example is a soft-tissue hemangioma undergoing involution. Active tumors continue to grow but are constrained by anatomic boundaries. They usually require surgery either by intralesional or marginal excision. Common examples are enchondromas and .
