Demographic Characteristics, Anatomical Distribution, and Clinical Presentations of Lipomatosis Tumors Arising from Hand and Wrist

Abstract

The aim of this study is to analyze demographic characteristics, anatomical distribution, and clinic presentations of the lipomatosis masses in hand and wrist. The hand and wrist magnetic resonance (MR) images of 2,453 patients were evaluated retrospectively. Nineteen cases were included in the study that is seen fat component in mass in MR images. Patients' age, sex, and clinical symptoms were noted. The size and the localization area of the mass were evaluated. Ordinary lipomas were detected in 18 (95%) patients, and fibrolipomatous hamartoma of the median nerve was detected in 1 patient (5%). Benign ordinary lipomas were most frequently observed in palmar and ventral sides. Lipomas located in palmar area tend to be bigger size comparing with other locations. Deep-seated lipoma is localized in central area frequently. In ordinary lipoma cases, patients are generally (78%) asymptomatic. The most frequent clinical symptom is limitation in movement depending on mass dimension.

A Case of Intramuscular Lipoma of Thenar Eminence With a Short Review of Published Hand Lipoma Case Reports

“…The presence of thick unyielding palmar fascia is believed to cause the larger lipomas to present peripherally on the palm and along the carpal tunnel, and at the same time, the palm due to its unique anatomy and gap under the palmar fascia gives rise to deceptively larger lipomas than other sites [ 8 , 9 ]. While operating, the same anatomical configuration necessitates the need for more extensive dissection [ 10 , 11 ]. Some of the lipomas can be seen extending across from the dorsum to the palmar aspect of the hand and need a dual incision on the hand to completely remove them [ 8 ].…”

“…In most cases, MRI imaging can delineate the diagnosis with good accuracy but in cases of radiological uncertainty, an image-guided biopsy has been recommended by Cribb et al [ 15 ]. Interestingly, there were cases where the MRI showed a malignant potential but was completely ruled out after biopsy [ 10 ].…”

Giant Lipofibromatous Hamartoma of Median Nerve in a Child

“…Also, macrodactyly of the involved limb or digit can be present in 66% of the cases 1 . The WHO classification of soft tissue tumors categorizes LFH as an adipocytic tumor, due to hypertrophy of mature fat and fibroblasts in the epineurium 2 . Table 1 presents a list of 15 cases obtained in a PubMed search of articles between 2012 and 2022 using the terms (Fibrolipomatous hamartoma) AND (median nerve).…”

Simultaneous Median and Ulnar Compression Neuropathy Secondary to a Giant Palmar Lipoma: A Case Report and Review of the Literature

“…However, a palmar subaponeuratic lipoma is the most common type of location. In a study that reviewed 18 cases of hand lipoma, 14 (78%) cases were located in the deep palmar area [ 2 ]. A deep-seated palmar lipoma may cause nerve compression syndromes when settled in the hand due to the limited space.…”
