Diagnostic Considerations

Failure to diagnose cancer is one of the most frequent reasons for medical malpractice actions. Accordingly, any suggestive symptoms should be thoroughly investigated. In the setting of a known cancer, failure to diagnose the correct subtype of lymphoma and subsequent use of treatment for a different type of lymphoma or other malignancy that is not optimal therapy for mucosa-associated lymphoid tissue (MALT) lymphoma (MALToma) is a medicolegal hazard.

In addition to the conditions listed in the differential diagnosis, other problems to be considered include the following:

  • Extranodal lymphoma
  • Gastric lymphoma
  • Low-grade non-Hodgkin lymphoma (NHL)
