Primary cutaneous B-cell lymphoma (PCBCL) is an heterogeneous group of lymphoproliferative disorders, which account for 25-30% of all primary cutaneous lymphoma and include three main histotypes: 1) primary cutaneous marginal zone B-cell lymphoma (PCMZL); 2) primary cutaneous follicular center cell lymphoma (PCFCL); 3) primary cutaneous diffuse large B-cell lymphoma (DLBCL), leg type (PCDLBCL-LT). PCMZL and PCFCL are indolent lymphomas, with an excellent prognosis despite an high rate of cutaneous recurrences; in contrast, PCDLBCL-LT is clinically more aggressive and usually requires to be treated with multi-agent chemotherapy and anti-CD20 monoclonal antibodies. PCDLBCL-LT histologically consists of large round cells (centroblasts and immunoblasts), is characterized by strong bcl-2 expression, in the absence of t(14;18) translocation, and resembles the activated B-cell type of nodal DLBCL. Recently, the term primary cutaneous DLBCL-other (PCDLBCL-O) has been proposed to include diffuse lymphomas composed of large transformed B-cells that lack the typical features of PCDLBCL-LT and do not conform to the definition of PCFCL. Some clinical studies suggested that such cases have an indolent clinical course and may be treated in a conservative manner; however, data regarding the actual prognosis and clinical behaviour of these peculiar cases are still too limited. The spectrum of primary cutaneous DLBCL also encompasses some rare morphological variants, such as anaplastic or plasmablastic subtypes and T-cell rich B-cell lymphoma, and some recently described, exceedingly rare DLBCL subtypes, such as intravascular large B-cell lymphoma and EBV-associated large B-cell lymphoma of the elderly, which often present in the skin.
Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am.
Very much believe in "Sing your own song - weave your own tapestry"
Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow.
Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue.
Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet.
Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys.
Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
