Members of the CAP Surgical Pathology Committee are asking for your assistance in providing material for future mailings of the Performance Improvement Program in Surgical Pathology (PIP).

The following list includes some of the specimens that are desirable, but all surgical pathology diagnoses are considered for inclusion in PIP. The CAP will gratefully accept any well-fixed prion disease-free paraffin embedded diagnostic material. Tissue submitted in formalin (wet tissue) will not be accepted. Approximately 30 paraffin blocks are required to provide the glass slides for a single case. The CAP will accept blocks with multiple pieces of tissue if it is more convenient. The CAP cannot accept wet tissue donations for the PIP program.
