Nasopharyngeal carcinoma with cutaneous metastases

Cutaneous metastases from nasopharyngeal carcinoma are extremely rare and associated with a poor prognosis.

We retrospectively reviewed 820 patients with nasopharyngeal carcinoma treated over a 20-year period in the radiotherapy department of Farhat Hached hospital in Sousse and Ibn Khaldoun Medical centre, Hammam Sousse. Two of these patients presented cutaneous metastases. The skin lesions appeared during radiotherapy and 3 months after treatment of the primary tumour. Cutaneous metastases present as multiple painless nodules and erythematous plaques. Cutaneous metastases were associated with other metastatic sites (liver, bone). One patient received chemotherapy. Both patients died in a context of rapidly progressive disease.

Nasopharyngeal carcinoma with cutaneous metastases is a rapidly fatal disease. In the light of these two cases and a review of the literature, patients with this disease are aged between 30 and 63 years with a marked male predominance. Cutaneous metastases are correlated with a more advanced primary tumour. The main sites are the trunk and scalp. There is no standard treatment modality for this disease and survival does not exceed 9 months.
