Cutaneous Metastasis of Head and Neck Malignancy

Abstract

ABSTRACT Background Noncutaneous cancers of the head and neck occasionally metastasize to skin. We present a case series of patients with skin metastases from non-cutaneous malignancies of the head and neck. A literature review is presented to assess the morphology, pattern of distribution, and morbidity of skin metastases. Methods Relevant cases were identified by a dermatopathologist and cases were reviewed. A literature search yielded 94 cases which were also included. Results The most common primary site, histology, and location of spread was the thyroid gland (42%), squamous cell carcinoma (42%), and scalp (25%) respectively. Skin metastases typically present as a discrete nodules, but the distribution varies. Metastases to skin can occasionally be a patients presenting complaint, but irrespective of timing of presentation portend a poor prognosis. Conclusion Skin metastases are clinically rare, and when present typically herald a poor overall prognosis. Information regarding their distribution and clinical presentation is of importance to the surgeon and oncologist. How to cite this article Emanuel H, Emanuel P.
