Cutaneous squamous cell carcinoma has a relatively low metastatic rate (0.5% to 16%), but patients with the disease should always be evaluated for possible regional nodal involvement. We reviewed the records of 37 patients with metastatic disease among the 388 patients with head and neck cutaneous squamous cell carcinoma who were treated at New York University Medical Center between 1961 and 1992. In this group of patients the most common primary sit was the cheek or preauricular region and the most common metastatic site was the level I neck lymph nodes. Seven patients (18%) had metastases at initial presentation. Among the remaining patients the average time to the development of metastases was 19 months. Nineteen patients (51%) had recurrence at the primary site before metastasis; 11 (30%) developed metastases with control of the primary tumor. Analysis of the records of 31 patients treated for cure revealed that 13 were treated by surgery, 2 by radiation therapy, and 16 by a combination of surgery and radiation therapy. During the mean follow-up period of 49 months, 11 (35%) of these 31 patients died of their disease. Recurrence of the primary tumor appeared to increase the risk for nodal and distant metastases.

Metastases are occasionally associated with cutaneous squamous cell carcinoma but only rarely with basal cell carcinoma There are approximately 200 cases of metastases from basal cell carcinoma reported in the world literature. We describe 6 additional cases. All of our patients demonstrated recurrence at the primary site before they developed their metastases, Metastases presented in subcutaneous tissue, cervical lymph nodes, bone, and lung between 1.5 and 14 years after initial treatment of the primary lesion The long interval seen in these patients between the initial treatment of the primary and the development of metastases underscores the need for long-term follow-up in what is often thought to be a nonaggressive, nonmetastasizing malignancy.
