Thymus in Lymphoma

Lymphoma is a disease of lymph organs.
The thymus and lymph nodes are lymph organs.

Mediastinal widening can result from enlargement of both of these.

However, if the question is talking about the anterior mediastinum then it must be the thymus not lymph nodes.

There's a new classification of lymphoma and one of them is not called Mediastinal Lymphoma and it represents 5% of cases and it affects the thymus to read more about go here http://emedicine.medscape.com/article/203681-overview

my confusion was because i was just thinking of lymph nodes as only source of lymphoma:eek: .even if i was not thinking of thymus i should have thought of mediastinal lymph nodes!
anyhow,now after checking the link,i have new q! how come we can have lymphoma of B cells in thymus?? should not all thymus lymphomas be of T cell?
?
