Abstract

Purpose: Deep palmar tumors of the hand are very rare, and reported cases are usually benign. The most important issue is frequent anatomical variations with challenging surgical exposure and excision of these lesions. Some case reports or a small series of patients have been reported in the literature. The aim of this study was to present our experience with the deep palmar tumors of the hand. Patients and Methods: In the study, retrospective analyses of 43 patients treated with deep palmar tumors of the hand between January 1998 and June 2015 were evaluated. Tumors and tumor-like pathologies of the deep palmar space of the hand were retrospectively evaluated according to age, gender, localization, preoperative symptoms, size, site, treatment methods, histopathology, and early and late complications. Statistics and data analyses were also performed. Results: All 43 pathologies were benign, and histopathologic diagnoses were 10 lipomas, 8 ganglions, 5 giant cell tumor of the tendon sheath, 4 schwannomas, 3 hemangiomas, 3 palmar fibromatosis, 2 epidermal cysts, 2 neurofibroma, 1 angiolymphoid hyperplasia with eosinophilia, 1 granuloma, 1 calcifying aponeurotic fibroma, 1 digital fibroma, 1 foreign body granuloma, and 1 lipofibromatous hamartoma. The most common complication was temporary numbness and paresthesias of the digits. Marginal excision was performed in 40 patients, excision with nerve grafting in 2 patients (with neurofibroma) and carpal tunnel release in one patient with lipofibromatous hamartoma. Conclusion: In the deep palmar space of the hand, pathologies are closely associated with tendons, muscles, and neurovascular structures. Preoperative magnetic resonance imaging is helpful for the preoperative diagnosis, evaluating tumor extension, and successful surgical planning. Level of Evidence: IV Therapautic
