CUTANEOUS METASTASES of well-differentiated thyroid carcinoma (DTC) are very rare and infrequently they are the presenting feature. In these cases immunohistochemical determination of thyroglobulin (Tg) on the metastatic lesion led to the diagnosis of the thyroid cancer. We present the case of a 65-year-old female who noticed early in 2002 a pigmented nodule approximately 1 cm in diameter on her scalp. In March 2003 the nodule was removed and histopathology revealed “cutaneous metastasis from solid carcinoma of follicular type”. Immunohistochemistry of the cutaneous specimen was positive for Tg thus allowing the diagnosis of metastatic differentiated thyroid cancer.

Abstract
CUTANEOUS METASTASES of well-differentiated thyroid carcinoma (DTC) are very rare and infrequently they are the presenting feature. In these cases immunohistochemical determination of thyroglobulin (Tg) on the metastatic lesion led to the diagnosis of the thyroid cancer. We present the case of a 65-year-old female who noticed early in 2002 a pigmented nodule approximately 1 cm in diameter on her scalp. In March 2003 the nodule was removed and histopathology revealed “cutaneous metastasis from solid carcinoma of follicular type”. Immunohistochemistry of the cutaneous specimen was positive for Tg thus allowing the diagnosis of metastatic differentiated thyroid cancer.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
