Mantle cell lymphoma

Bone marrow involvement of mantle cell lymphomaの症例

 
BM involvement of MCL02.jpg

骨髄骨梁間に密なASD-Giemsa陰性の小型~中型円形細胞の浸潤が認められる.

MCLは60-90%の症例で骨髄に浸潤する. *1*2*3*4*5. 骨髄浸潤の最も一般的なパターンは, focal random(限局性, ランダム)で, 80%以上の症例でみられる.

骨梁間(interstitial)には約50%, びまん性浸潤は20~30%の症例でみられる。*1,*6 とくに, 傍骨梁浸潤は45%の症例に認められる. 時には、濾胞性リンパ腫に似た傍骨梁のみの浸潤を認めることもある. まれに、顕著な類同内浸潤を伴う症例も報告されている。*7
