Abstract:
A 91-year-old Hispanic man with a diffuse large B-cell lymphoma of the stomach that was currently being treated with immunosuppressive therapy was referred for evaluation of a biopsy-proven squamous cell carcinoma in situ (SCCis) on the left mid-region of his back. The lesion had apparently been present at birth and had recently started to itch, become red, and progressively enlarge.
