Rare Benign Tumors and Tumor-Like Lesions of the Hand without Skin Damage—Clinical, Imagistic and Histopathological Diagnosis, Retrospective Study

Abstract

Background: The broad spectrum of diagnoses and clinical features of hand tumors and the absence of pathognomonic signs often lead to an inaccurate or delayed diagnosis. However, only a few reports have comprehensively referenced the diagnosis and clinical features of hand tumors. This study intends to highlight the clinical, imaging and histological characteristics of uncommon hand tumors or tumor-like lesions. Methods: In this retrospective study, we report a series of 80 patients diagnosed with rare hand tumors and tumor-like lesions without skin damage. Age, gender, tumor location, imaging examinations and clinical and laboratory findings were analyzed. The histopathological exam established the final diagnosis. Surgery was indicated and performed in all cases. Results: This study included: neurofibroma, glomus tumor, lipoma, schwannoma, epidermal inclusion cyst and idiopathic tenosynovitis with “rice bodies.” We have described the clinical, imagistic and histopathological particularities of these tumors. Surgical management included the complete removal of tumors, with no recurrence recorded within two years and overall high patient satisfaction. The most common findings were lipomas and the rarest neurofibromas. Conclusions: To optimize the care of hand tumors and reduce diagnostic and treatment errors, knowledge of hand tumor types and their clinical and laboratory characteristics is necessary for every surgeon.

Solitary Glomus Tumor on the Base of the Right Thumb: A Rare Case Report and a Literature Review from Saudi Arabia

“…The direct complete excision offered a greater chance of a cure and thus a better functional outcome. 53,54 Documenting occurrence of glomus tumor cases in unusual locations in the literature raises awareness of this condition and reduces the time needed for diagnosis, which could be very long and contribute to severe morbidity to the patient. In order to completely remove glomus tumors and prevent recurrence, accurate preoperative localization is essential.…”

Various hand tumors: over 20 years of clinical experience in Korea

“…As a very sophisticated and functional body part, the diagnosis and treatment of bone and soft tissue tumors of the hand are important. Most tumors originate from soft tissue, and most of them show benign findings [1,2]; however, benign tumors of the hand are less common than in other sites, and some are rare [3,4]. Therefore, a diagnosis based solely on clinical features is difficult, requiring extensive knowledge.…”

“…Therefore, a diagnosis based solely on clinical features is difficult, requiring extensive knowledge. Only a few clinical studies have comprehensively addressed the characteristics and diagnosis of tumors or tumor-like lesions in the hand [1,5,6]. The purpose of this study is to find out the types of hand tumors in Korean and to review the diagnostic modality usually used.…”
