Paraneoplastic rash as the presenting feature of squamous cell carcinoma of the lung.

We report on the case of a man who presented with a severe, pruritic rash 5 months prior to diagnosis of a resectable lung malignancy. A rash is a rare presentation of squamous cell carcinoma of the lung but may be the only feature of a potentially curable malignancy. Treatment of the underlying malignancy resulted in complete resolution of the rash.
