Unknown: a warm, painful nodule on the back

Dermatol Online J. 2012 Aug 15;18(8):9.

Abstract

A 67-year-old man presented with a complaint of a painful nodule on his back for approximately two months. On exam, a violaceous, firm, warm, indurated nodule measuring 3.5 x 2 cm was observed. Nine months prior to presentation, he was diagnosed with a moderately differentiated squamous cell carcinoma (SCC) of the left upper lobe (stage 1b), which was removed via video-assisted thoracoscopic wedge resection. Diagnosis of metastatic SCC secondary to traumatic seeding at a trocar port site was made. To our knowledge, this has not been previously described in the literature.
