Isolated Skin Metastasis From Papillary Thyroid Carcinoma: A Rare Presentation

Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy and is often characterized by a high rate of regional lymph node involvement. However, distant metastasis is uncommon, and cutaneous metastases are particularly rare, occurring in fewer than 0.1% of cases. This report presents an unusual case of isolated skin metastasis as the first manifestation of distant spread in PTC. The case highlights the diagnostic challenges associated with this rare presentation, explores potential mechanisms underlying cutaneous dissemination, and underscores the significance of a multidisciplinary approach to management. The findings emphasize the importance of long-term surveillance and meticulous pathological evaluation in patients with PTC, particularly in cases with atypical metastatic patterns.
