Abstract
OBJECTIVES: Establish and validate optimal minimal immunohistochemistry panels for usage in a staged algorithmic manner for precise diagnosis of B-cell lymphomas in countries with limited resources. Suggest short panels of immunostains to be used in referring units that refer suspected lymphomas to specialist diagnostic centers in resourceful countries.
METHODS: Significant proportion of six B-cell lymphomas has characteristic morphology requiring a short panel of confirmatory immunostains. The rest would go through five different algorithms.
RESULTS: 812 cases in which a B-cell lymphoma or an HIV-associated lymphoma was suspected on morphological grounds were evaluated. This led to arriving at a specific diagnosis of 799 B-cell lymphomas. A correct diagnosis was achievable in 69% cases with the application of three to five antibodies; others required additional work-up.
CONCLUSIONS: The panels/algorithms assist pathologists in practicing lymphoma diagnostics in countries with limited resources and in making lymphoma referrals to specialist centers.
