Epidemiological and histopathological analysis of soft tissue tumors of the hand - 9 years of experience from a single center

Abstract

Objectives: The spectrum of soft tissue tumors of the hand is wide. The type of tumor can vary based on demographicfactors, such as a patient’s gender and age. Furthermore, certain tumors arise more commonly in particular locations on thehand. This study aimed to determine the incidence and recurrence rates of soft tissue tumors of the hand and to discuss themost common types of tumors based on tumoral parameters, demographic data, and histopathological findings with a briefreview of the literature.Methods: We analyzed the clinical data and the pathology reports of all patients who underwent surgery in our hand andmicrosurgery department between January 1, 2007, and January 1, 2016. We evaluated the demographic data, surgicalinformation, tumor type, size and location, histopathological diagnoses and immunohistochemical findings. We also determinedthe recurrence rates of the patients after a 2-year follow up.Results: In our center, 302 surgical resections were performed between January 1, 2007, and January 1, 2016. Ganglion,which is a pseudotumoral lesion, was the most common space occupying lesion (n=102, 34%). Of the 302 resections, 66%were tumoral cases (n=200). Giant cell tenosynovial tumor (n=55, 27.5%) was the most common benign tumor, followed byglomus tumor (n=34, 17%), pyogenic granuloma (n=15, 7.5%), and cystic hygroma (n=14, 7%).Conclusion: In accordance with the literature, in the present study, most of the patients (99%) that underwent surgery hadbenign diagnoses. Synovial sarcoma was the only malignant tumor observed in the study population.
