CUTANEOUS METASTASES FROM PRIMARY CARCINOMA LARYNX - A RARE PRESENTATION

The incidence of secondary cutaneous deposits from squamous cell carcinoma larynx is very rare. We report a sixty nine year old male who was diagnosed with squamous cell carcinoma of larynx who was treated with radiotherapy and chemotherapy, presented with multiple grouped nodules over the neck in a zosterifom pattern. Eventhough nodular, plaque-like, exuberant growth and sclerodermoid skin metastases have been described in laryngeal carcinoma, metastases to the skin in a grouped pattern is uncommon with only one case reported so far in the literture. The possible hypothesised cause of dermatomal metastatic distribution my be secondary to perineural lymphatic invasion and invasion of dorsal root gangliaby malignant cells.
