Skin Metastasis of Laryngeal Carcinoma Presenting as Multiple Eruptive Nodules.

Metastasis of head and neck squamous cell carcinoma (SCC) to the skin of this region is extremely rare and reported in 1-2% of cases. The cutaneous metastases of head and neck cancers often present as multiple papulonodular lesions; however, sporadic cases of solitary or multiple keratoacanthoma-like lesions are reported. We describe a rare case of cutaneous metastases of laryngeal SCC presenting as multiple eruptive keratoacanthoma-like lesions with concomitant scrofuloderma in an area of previous radiotherapy.
