Because of the critical anatomic position of the parotid duct, malignancy of this structure presents a serious cosmetic and surgical management problem both to the patient and to the physician. The paucity of experiences and therapeutic guides in the literature is attributable to the rarity of this disease entity, only six cases having been reported. No case of parotid duct malignancy in which carcinogenic constituents of carbon black are implicated has heretofore been reported.
Goforth1 reported an anaplastic epidermoid carcinoma in the parotid duct of a 60-year-old woman. The tumor was excised, along with a small segment of the duct and a small amount of cheek tissue. The excisional site was treated with radium. A single cervical lymph node revealed metastatic cancer. A radical neck lymph node dissection was not performed. The patient died of widespread tumor metastases one and one-half years later.
