Increase in the number or proportion of lymphocytes in the blood. [from HPO]

Persistent polyclonal B-cell lymphocytosis (PPBL) is characterized by chronic, stable, persistent, and polyclonal lymphocytosis, the presence of binucleated lymphocytes in the peripheral blood, and a polyclonal increase in serum IgM. It is significantly associated with cigarette smoking (summary by Cornet et al., 2009). [from OMIM]

A neoplasm characterized by the absence of atypical or malignant cytological and architectural features, and absence of invasive features or metastatic potential. [from NCI]

Classic Hodgkin lymphoma is a lymph node cancer of germinal center B-cell origin. Hodgkin lymphoma tumors consist of a minority of malignant cells, known as 'Reed-Sternberg' (RS) cells, mixed with reactive lymphocytes and other benign inflammatory cells. A defining feature of RS cells is the presence of 2 nuclei (summary by Salipante et al., 2009). [from OMIM]

Behavior or an act aimed at harming a person, animal, or physical property (e.g., acts of physical violence; shouting, swearing, and using harsh language; slashing someone's tires). [from HPO]

A disease involving leukocytes. [from MONDO]

A rare genetic multiple congenital anomalies/dysmorphic syndrome characterized by almost complete lack of B-cells and severe hypogammaglobulinemia, anomalies of the hands and feet, urogenital malformations, and characteristic facial dysmorphism (including microcephaly, highly arched eyebrows, hypoplastic alae nasi, and micrognathia). Most patients are developmentally normal, although moderate mental retardation has also been described. [from ORDO]

A subtype of classic Hodgkin lymphoma with scattered Hodgkin and Reed-Sternberg cells and a nodular or less often diffuse cellular background consisting of small lymphocytes and with an absence of neutrophils and eosinophils. (WHO, 2008) [from NCI]
