WBC Disorders Flashcards
Toxic granulatiins, dohke bodies, cytoplasmic vacuoles seen in
Leukocytosis
Lymphoid neoplasm
Tumors of B cells, T cells, and NK cells
Myeloid neoplasams
Acute myeloid leukamias
Myelodysplastic syndrome
Myeloproliferative neoplasm
Histiocytoses
Proliferative lesions of macrophages and dendritic cells
Acute lymphoblastic leukemia(ALL)
Mostly BCells
Mutation in NOTCH 1 for TCell development
B cell mutation are PAX 5,TCF3, ETV6 AND RUNX1
Chronic lymphocytic leukamia
Make predominance
Deletions in 13q14.3, 11q and 17p and trisomy 12q
Overexpression of antiapoptotic protein BCL2
Smudge cells or disrupted tumor cells are seen in
Chronic lymphocytic leukemia
Ritcher syndrome
Cll or sll transform into more aggressive tumor into diffuse large B cell lymphoma
Indolent waxing and waning course seen in
Follicular lymphona
Involves chromosomal translocations involved in BCL2 gene of chromosome 18 and IGH locus on Chromosome 14
Diffuse large b cell lymphoma
Treatment anti cd 20 (rutiximab)
Due to BCL 6 overexpression
Break point in bcl6 at chromosome 3q27
Most common type of non hodgkin lymphoma
Burkitt lymphona
Translocations of MYC gene on chromosome 8
Tingile body macrophages seen in
Burkitt lymphoma we can see as starry sky appearance
Splenomegaly and pancytopenia seen in
Hairy cell leukemia and acute myeloid leukemia and in splenomegaly
Mutation in threonine kinase BRAF
DOWNSTREAM OF RAS IN MAPK SIGNALING
Multilobed or clover leaf nuclei seen in
Adult TCell leukemia
Involves cd4+Tcrlls in adults infected by HTLV 1
Involves CD4+ and involves skin with 3 types of phases
Mycosis fungoides
Patch phase
Plaque
Tumor phase
