A 65-year-old Taiwanese woman presented with a 10-year history of a slow-growing asymptomatic mass in her left preauricular area. Her medical history was unremarkable, and no pertinent family history was reported.
Physical examination revealed a movable, elastic, nontender subcutaneous nodule, measuring approximately 2 cm in diameter, in the left preauricular area (Figure 1). The nodule was excised for histologic examination (Figure 2 and Figure 3).
