title: Tumor seeding associated with bone marrow aspiration and biopsy.
abstract: A 53-year-old man with small-cell lung carcinoma underwent bone marrow aspirations and biopsies for tumor staging and harvest for autologous bone marrow infusion. Fourteen months after bone marrow aspiration and biopsy, a subcutaneous lesion grew over the posterior iliac crest, and a biopsy specimen disclosed small-cell carcinoma. To our knowledge, this is the first case report of tumor seeding associated with bone marrow aspirate and biopsy.
