(kas′ĕl-măn) [Benjamin Castleman, U.S. pathologist, 1906–1982] ABBR: CD. An occasionally aggressive illness marked by excessive growth of lymphoid tissue either localized in a single lymph node group (unicentric) or in multiple regions of the body (multicentric).
INCIDENCE: The disease is rare; it occurs in about 1 in 1,000,000 people.
CAUSES: Although the cause is not precisely known, its associations with HIV/AIDS, Kaposi sarcoma, and human herpesvirus 8 infection have led some to propose that it has an infectious basis.
SYMPTOMS AND SIGNS: Many people experience no symptoms for unicentric CD; however, patients with a very large mass may experience: a feeling of fullness in the upper abdominal area; a lump under the skin in the lymph node area (neck, armpit, or groin); weight loss; cough; or anemia. For multicentric CD, symptoms usually include fever, night sweats, loss of appetite, weight loss, weakness, fatigue, enlarged lymph nodes, enlarged liver or spleen, and/or nerve damage in the hands or feet.
DIAGNOSIS: Biopsy of an enlarged lymph node.
TREATMENT: Localized disease responds well to surgical resection. Widespread disease can sometimes be treated effectively with chemotherapy, corticosteroids or immunotherapy. CD patients with HIV have a more difficult time eradicating the disease than non-HIV infected patients because of the other diseases that are usually associated with HIV.
PATIENT CARE: The health care team supports the patient medically and psychologically by providing education about the disease and its treatment, answering questions, providing comfort, and alleviating anxiety. SYN: angiofollicular lymph node hyperplasia.
