AGGRESSIVE NON HODGKIN LYMPHOMA (NHL) EBMT 2015 CLINICAL CASE

CLINICAL CASE Mr L. N. 64 year old presented with a microcytic anemia: Hb: 11.3 g/100ml MGV: 79 fl And an iron deficiency: Serum iron: 5 μ mol/L Ferritin: 8.5 μ g/L

An ileo-coloscopy evidenced a submucosal tumor (30x40 mm) The biopsies revealed a lymphomatous polyposis expressing CD20 CLINICAL CASE

The thoraco-abdominopelvic CT scan highlighted: Mediastinal lymph nodes Bilateral axillary lymph nodes A splenomegaly (19 cm) A bulky retro-pancreatic mass (60x40 mm) A bulky colic mass (80x65 mm) with adjacent lymph nodes Inguinal lymph nodes. The trephine bone marrow biopsy did not evidenced lymphomatous invasion. CLINICAL CASE

Question 1: What is the clinical stage based on these informations? CLINICAL CASE

NHL - Initial Staging Evaluation of number and location of cancerous lymph nodes Stage IStage I : single Lymph Node region or single extra lymphatic organ/site (IE) Stage IIStage II: 2 or more LN regions on the same side of the diaphragm or single extra nodal site with adjacent nodes (IIE) Stage IIIStage III: nodal regions on both sides of the diaphragm Stage IV: disseminated involvement of one or more extralymphatic organs: bone marrow, liver, brain… Ann Arborr staging I –IV, B: presence of symptoms: unexplained fever, unexplained >10% weight loss, sweats

After review of the biopsy samples, the final conclusion is: Mantle Cell Lymphoma (MCL) CLINICAL CASE
