Abstract

We report a case of malignant melanoma of the right neck with lung metastasis, which was found 22 years after the primary lesion excision, lymph node dissection, and adjuvant therapy. A 47-year-old woman was given a diagnosis of malignant melanoma of the right neck in 1987, and underwent surgical excision and cervical lymph node dissection, as well as OK432 local administration. The tumor had a Breslow tumor thickness of 0.6 mm and was identified as pT1aN0M0, Stage IA. Since no local recurrence or metastasis were observed after a year, she stopped periodic follow-up examinations. Twenty-two years after the initial treatment, an abnormal shadow was detected by chest X-ray and PET/CT revealed a nodule at the posterior segment of the right lung (S2). A right superior lobe resection and mediastinal lymph node dissection were performed. Metastatic malignant melanoma of the lung and lymph node metastases were diagnosed by histological examination. No recurrence or metastasis have been found after 6 courses of DAC-Tam therapy. Because malignant melanoma can metastasize even after 22 years, it is necessary to carefully monitor patients with malignant melanoma.
