Introduction: Tumors in the hand are rare, and malignant tumors in the hand are peculiar; However, primary pseudotumoral lesions of the hand, such as ganglion, are very frequent. Most of the tumors found in the bone and soft tissue can be presented in the same way in the hand but their frequency and distribution is different. Despite the low incidence of benign and malignant tumors in the hand, these can be locally invasive or compromise the hand function. The main objective of this study is to determine the epidemiology, types, location and management of tumors and pseudotumors of the hand in adults in the Mexican population., Material and Methods: We designed a retrospective study by review of clinical records of patients in our institution with diagnosis of tumors or pseudotumors in hand from January 2007 to December 2016 evaluating variables such as age, gender, laterality, Diagnosis, histological lineage, localization and treatment., Results: Our study comprises 215 patients with an average age of 44.23 years, predominantly women. Pseudotumors are the most frequently encountered (synovial cyst), followed by benign soft tissue tumors, benign bone tumors, and, finally, malignant tumors., Discussion: After all we suggests a possible new classification for the hand that is simple, reproducible and give guidance for treatment. The need for a classification system is imminent to standardize diagnostics, guide future research, focus treatments and preserve hand function.
