Other comments
Precursor T-cell leukemia/lymphoma 40% of lymphomas in childhood. Lymphoblasts with irregular nuclear contours, condensed chromatin, small nucleoli and scant cytoplasm without granules. TdT, CD2, CD7 It often presents as a mediastinal mass because of involvement of the thymus. It is highly associated with NOTCH1 mutations. Most common in adolescent males.
Follicular lymphoma 40% of lymphomas in adults Small "cleaved" cells (centrocytes) mixed with large activated cells (centroblasts). Usually nodular ("follicular") growth pattern CD10, surface Ig 72–77% Occurs in older adults. Usually involves lymph nodes, bone marrow and spleen. Associated with t(14;18) translocation overexpressing Bcl-2. Indolent
Diffuse large B cell lymphoma 40 to 50% of lymphomas in adults Variable. Most resemble B cells of large germinal centers. Diffuse growth pattern. Variable expression of CD10 and surface Ig 60% Occurs in all ages, but most commonly in older adults. Often occurs outside lymph nodes. Aggressive.
Mantle cell lymphoma 3 to 4% of lymphomas in adults Lymphocytes of small to intermediate size growing in diffuse pattern CD5 50% to 70% Occurs mainly in adult males. Usually involves lymph nodes, bone marrow, spleen and GI tract. Associated with t(11;14) translocation overexpressing cyclin D1. Moderately aggressive.
B-cell chronic lymphocytic leukemia/lymphoma 3 to 4% of lymphomas in adults Small resting lymphocytes mixed with variable number of large activated cells. Lymph nodes are diffusely effaced CD5, surface immunoglobulin 50%. Occurs in older adults. Usually involves lymph nodes, bone marrow and spleen. Most patients have peripheral blood involvement. Indolent.
MALT lymphoma ~5% of lymphomas in adults Variable cell size and differentiation. 40% show plasma cell differentiation. Homing of B cells to epithelium creates lymphoepithelial lesions. CD5, CD10, surface Ig Frequently occurs outside lymph nodes. Very indolent. May be cured by local excision.
Burkitt's lymphoma < 1% of lymphomas in the United States Round lymphoid cells of intermediate size with several nucleoli. Starry-sky appearance by diffuse spread with interspersed apoptosis. CD10, surface Ig 50% Endemic in Africa, sporadic elsewhere. More common in immunocompromised and in children. Often visceral involvement. Highly aggressive.
Mycosis fungoides Most common cutaneous lymphoid malignancy Usually small lymphoid cells with convoluted nuclei that often infiltrate the epidermis, creating Pautier microabscesses. CD4 75% Localized or more generalized skin symptoms. Generally indolent. In a more aggressive variant, Sézary's disease, there is skin erythema and peripheral blood involvement.
Peripheral T-cell lymphoma-Not-Otherwise-Specified Most common T cell lymphoma Variable. Usually a mix small to large lymphoid cells with irregular nuclear contours. CD3 Probably consists of several rare tumor types. It is often disseminated and generally aggressive.
Nodular sclerosis form of Hodgkin lymphoma Most common type of Hodgkin's lymphoma Reed-Sternberg cell variants and inflammation. usually broad sclerotic bands that consists of collagen. CD15, CD30 Most common in young adults. It often arises in the mediastinum or cervical lymph nodes.
Mixed-cellularity subtype of Hodgkin lymphoma Second most common form of Hodgkin's lymphoma Many classic Reed-Sternberg cells and inflammation CD15, CD30 Most common in men. More likely to be diagnosed at advanced stages than the nodular sclerosis form. Epstein-Barr virus involved in 70% of cases.

Famous quotes containing the word comparison:

    [Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?
    Sarah M. Grimke (1792–1873)

    In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.
    Henry David Thoreau (1817–1862)

    From top to bottom of the ladder, greed is aroused without knowing where to find ultimate foothold. Nothing can calm it, since its goal is far beyond all it can attain. Reality seems valueless by comparison with the dreams of fevered imaginations; reality is therefore abandoned.
    Emile Durkheim (1858–1917)
