A 61-YEAR-OLD woman was referred with a 3-week history of a nontender, walnut-sized, preauricular mass. The mass spontaneously resolved 2 days before her appointment. During her visit, however, she was noted to have 2 firm, 1.5×1.0-cm nodules on her scalp that had appeared 4 months before her office visit. She had been told by her family physician that the nodules were sebaceous cysts, and no further treatment was recommended. Her medical history was noncontributory.
The physical examination revealed some firmness over her right temporomandibular joint, but no discrete mass was appreciated. Clear saliva was milked from Stenson ducts. The 2 nodules on her head were firm. One was violaceous. By palpation, they were more adherent to the surrounding tissue than is normally noted with sebaceous cysts. No lymphadenopathy was palpated, and the findings of the rest of the examination were normal. Excision of the scalp lesions was recommended.
