Diagnostic imaging of the tumor mass. (A) Ultrasound shows an encapsulated iso-hyperechoic avascular lesion extended dorsally from the II to the V metacarpal bone. (B) Axial, (C) coronal and (D) sagittal MRI images show a large hyperintense well-defined mass occupying the left hand recesses from the III to the IV.

It bridged the anterior and posterior compartments of the left hand (Figure 1(A)). The hyper intense mass extended from the volar to the dorsal surface of the left hand involving the superficial cutaneous plans (Figures 1(B-D)).
Surgical procedure and aspect of the tumor mass. (A) Curved skin incision over the IV inter-metacarpal space. (B) Inter-metacarpal ligament between the fourth and the fifth metacarpal bones. (C) The mass was pulled dorsally and dissected. (D) Lobular fatty mass after removal.

The mass was dorsally approached through a curved skin incision over the IV inter-metacarpal space (Figure 2(A)). The inter-metacarpal ligament between the fourth and the fifth metacarpal bones was left intact as there was enough space for the mass to be pulled dorsally and dissected (Figures 2(B,C)). It appeared as a lobular fatty mass (Figure 2(D)).
