Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of post-transplant lymphoproliferative disorder (PTLD) diagnosed on an inguinal lymph node biopsy with CT scan evidence of lymphadenopathy in the chest, abdomen and pelvis if the bone marrow is also involved?
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of intrasinusoidal diffuse large B-cell lymphoma involving lymph nodes, the liver and the bone marrow? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of Langerhans cell histiocytosis with extensive bony metastatic disease and lymphadenopathy? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is primary site coded when lymphoma is initially found in both lymph nodes and bone marrow, the pathology report is unavailable, and the physician only states that both areas are involved? See Discussion.
