Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma that makes up about 2.5% of non-Hodgkin lymphomas in the US. It usually presents at advanced stages in the 5th and 6th decades of life with generalized lymphadenopathy and bone marrow involvement. There may also be involvement of peripheral blood, spleen, liver, gastrointestinal tract (lymphomatoid polyposis), Waldeyer's ring, lung, and pleura.The characteristic translocation is t(11;14),involving CCD1 and the heavy chain locus.
Goodpasture syndrome is a rare but serious autoimmune disease that attacks the lungs and kidneys. The disease occurs when the body's immune system mistakenly produces antibodies against collagen in the lungs and kidneys. Collagen is a protein that helps form connective tissue.
