Giant Pilomatrixoma Presenting in the Posterior Thorax, a Rare Location and the Largest Described

Figure 1

The scoutogram (a) reveals a very large bulky mass within the posterior midback. Sagittal (b) and axial contrast enhanced CT images ((c) and (d)) show a large heterogeneous mass which is not completely imaged and partially extrinsically compressed in the gantry. The mass demonstrates central area of hypodensity consistent with necrosis as well as scattered, coarse calcifications. This mass is in close proximity to the superficial skin and subcutaneous tissue without much involvement of deep structures.
