Abstract
Introduction: The synchronous malignant melanoma of the neck and papillary thyroid cancer is rare but severe condition. Here, we describe the case of a patient with papillary thyroid cancer and melanoma invasivum cutis.
Case report: A 49-year-old man had a change on the neck at the last 3-4 months that he accidentally noticed. He had hoarse voice, was afebrile, did not sweat more than usual and feel exhausted, without rash or itching. MR examination of the neck and upper mediastinum before the surgery indicated a hyperintense focal change in the left thyroid gland which dimensions was 19 x 15 mm and several hyperintense inhomogeneous lymph glands of the jugular chain, on the both sides, with different sizes. On the basis of the conducted analyzes, in addition to total thyroidectomy, two-sided functional dissection of the lymph nodes of the neck was performed. The pathohistological diagnosis of the left lobus was: Carcinoma papillary glandulae thyreoideae invasivum (G-I, nG-I, pT2, Lx, Vo). CT of head, neck and thorax were made, where it was noticed that the CT of the head and lungs were normal. PET/CT findings indicated that there was no rest or recurrence of the tumor.
Conclusion: The message from this case report is that when diagnosing and treating thyroid cancer, the observed changes in the neck lymph nodes also indicate cancers of non-thyroid pathology such as malignant melanoma.
