The patient is a 40-year-old white female with a renal transplant greater than ten years ago. She currently has a nodule in the skin located on the left jaw line that has been present since June, 1999. A previous biopsy elsewhere reportedly demonstrated a lymphoplasmacytic infiltrate with a predominance of lambda positive plasma cells. This was felt to represent a cutaneous marginal zone lymphoma. This current biopsy specimen is submitted to further characterize the lymphoplasmacytic lesion in the skin.
