Retrospective analysis of upper limb soft tissue tumor in 635 cases

Abstract

Objective To study the characteristics of soft tissue tumor of upper extremity and explore the influences of related factors on benign and malignant tumors. Methods The clinical data of all the cases with upper extremity soft tissue tumors were collected and analyzed retrospectively from January 2013 to December 2015. Statistical analysis was performed on the characteristics of the disease and the related factors on benign and malignant tumors. Results A total of 635 cases of upper extremity soft tissue tumors were retrospectively analyzed, most of which were benign. The pathological types of benign tumors were as follows: ganglion cyst, hemangioma, epidermoid cyst, lipoma and giant cell tumor of tendon sheath. The incidence rate of ganglion cyst, lipoma and giant cell tumor of tendon sheath was higher in female, while epidermoid cyst was higher in male. The average age of onset was concentrated in 40 to 60 years of age. Lipoma is bigger than other tumors. Ganglion cysts occur more frequently in the wrist, lipoma in the forearm, hemangioma, epidermoid cyst and giant cell tumor of tendon sheath in the fingers. Gender, age, size and location of the tumor affected whether it was benign or malignant. Conclusion Most of the soft tissue tumors in upper extremity were benign. Considering the characteristics of the disease is help to diagnosis. Large soft tissue tumors in the forearm of elder men were probably malignant.
