Zosteriform cutaneous metastases from squamous cell carcinoma of the stump of an amputated arm.

The clinical appearance of skin metastases varies over a wide morphologic spectrum, cutaneous metastases mimicking herpes zoster being rare. We now report the case of an 83-year-old male with zosteriform cutaneous metastases secondary to a squamous cell carcinoma (SCC) which developed in the stump of an amputated arm. The pathogenesis is speculative, but in this case, the zosteriform distribution might well be explained by perineural lymphatic invasion and spread.
