What does it mean when a fine needle aspiration shows atypical monomorphic lymphocytes?
Finding atypical monomorphic lymphocytes in a fine needle aspiration (FNA) of your left axillary (armpit) lymph node suggests abnormal lymphocytes are present, but this result alone isn't enough for a complete lymphoma diagnosis.
FNA biopsies use very small needles that collect limited cell samples. While they can detect abnormal cells and may be useful for checking cancer relapse, the sample is typically too small to confirm a lymphoma diagnosis or determine the specific subtype.
Your doctor will likely recommend additional testing, which may include:
- An excisional or core needle biopsy to get a larger tissue sample
- Immunophenotyping to identify specific cell markers and determine if the cells are B cells or T cells
- Chromosome tests to check for genetic mutations
- Flow cytometry to analyze cell characteristics in more detail
These additional tests are important for determining the exact type of lymphoma, evaluating prognosis, and choosing the most effective treatment options. It's understandable to feel anxious waiting for more definitive answers, but getting a complete diagnosis will help your medical team create the best treatment plan for your specific situation.
