Which lymphoma typically shows a predictable pattern of lymph node spread?

• A. Presence of Reed-Sternberg cells and predictable lymph node spread pattern.
• B. Heterogeneous group of lymphoid cancers with variable aggressiveness and unpredictable spread.
• C. Malignancy of melanocytes in skin.
• D. Malignancy of plasma cells in bone marrow.

Answer: (A)

Hodgkin lymphoma tends to spread in an orderly, contiguous way through adjacent lymph node groups, rather than jumping to distant sites. This predictable pattern is a hallmark of the disease, reflecting how the cancer cells move along lymphatic pathways from one nodal region to the next. The presence of Reed-Sternberg cells in the lymph node biopsy is the classic histologic feature that identifies this lymphoma type. So, the option that links Reed-Sternberg cells with a predictable, stepwise spread through neighboring nodes best matches Hodgkin lymphoma. By contrast, many non-Hodgkin lymphomas show more variable, noncontiguous spread and can involve extranodal sites, while melanoma and multiple myeloma describe cancers of different cell types altogether.
