Suspected adipose tumours of the hand and the potential risk for malignant transformation to sarcoma: a series of 14 patients

Abstract

A case report of multi-compartmental lipoma of the hand

“…However, the dorsal approach reduced the post-operative pain compared to a double approach procedure, thus granting a faster recovery in the post-operative period due to lower swelling and scarring, and preventing the direct exposition and dissection of the ulnar neurovascular bundles and of the flexor tendons. This could explain why, in the present case, there was no reduction of both the grip and pinch measurement, while a strength reduction using a volar approach has been previously reported [ 4 ]. Finally, the natural history of the present case that remained asymptomatic and slowly growing for a decade represents a diversion from the majority of the hand-located lipomas, that naturally tend to have a faster grow-rate and can be rarely asymptomatic at the stage of the one discussed in the present report.…”

“…These lesions are characterized by a progressive enlargement and they can compromise the hand functionality. Giant lipoma sizing ≥50 mm should be removed due to the possibility of malignant transformation to sarcoma, despite the rare occurrence in the hand [ 4 , 5 ]. As reported by several reviews of the literature, lipomas infiltrating the deep layers of the hand are surgically approached and removed through the palmar aspect [ 6–11 ].…”

Atypical Sites of the Lipoma on the Hand and Fingers: Clinical and Imaging Features and Surgical Outcomes

“…Lipomas with a size greater than 10 cm are defined as “giant lipomas”, and are associated with a higher risk of malignancy [ 23 , 24 , 25 ]. A giant palmar lipoma infiltrates the deep layers of the hand [ 8 , 26 , 27 ].…”

Tumour in a tumour: a well-differentiated spindle cell sarcoma within a forearm lipoma

“…Although they are usually subcutaneous, they can occur in any tissue plane including intramuscular, however, tumours deep within the fascia account for <1% of all lipomas 6. They were historically considered rare in the upper extremity, particularly the hand, however, this concept has changed over time 7–10…”
