Which is a common clinical manifestation of Hodgkin disease?

A. Painful, enlarged lymph nodes is incorrect because in Hodgkin disease, the lymph node enlargement is usually painless. Painful nodes are more commonly associated with infections or inflammatory conditions, where the immune response triggers tenderness and discomfort. In Hodgkin disease, the cancerous lymphocytes infiltrate the nodes without causing acute inflammatory pain. B. Enlarged, firm, nontender lymph nodes is correct. The classic presentation of Hodgkin disease is the presence of firm, rubbery, nontender lymphadenopathy, most often in the cervical, supraclavicular, or mediastinal regions. The nodes are typically mobile early in the disease but may become fixed as the disease progresses. This type of lymphadenopathy is usually gradual and persistent, often discovered incidentally by the patient or during a routine exam. The nontender nature is a key distinguishing feature from infectious lymphadenopathy. C. Petechiae is incorrect because petechiae result from thrombocytopenia or coagulation disorders, not Hodgkin disease. While advanced Hodgkin lymphoma may eventually affect the bone marrow and platelet production, petechiae are not an early or common manifestation. D. Bone and joint pain is incorrect because this is not a typical presenting symptom of Hodgkin disease. Bone involvement may occur only in advanced stages, usually with other systemic symptoms.
