RESUMO
OBJECTIVES: To overcome the challenges associated with molecular and cytogenetic (MG) education in hematopathology (HP), a monthly joint HP/MG conference with specific curricular goals was established and evaluated by the participants. METHODS: All cases from the HP/MG conference over 56 months were reviewed. To assess the educational impact, a survey was distributed to current/former HP/molecular genetic pathology fellows and faculty. RESULTS: During the study period, a total of 252 cases covering MG testing considered important for HP fellowship training were presented. The 100 most recent cases since 2018 discussed findings of diagnostic (85%), prognostic (40%), or therapeutic (10%) importance. A broad range of technologies were discussed such as karyotyping, cytogenetic fluorescence in situ hybridization studies, microarrays, polymerase chain reaction-based tests, next-generation sequencing, and Sanger sequencing. Twenty-three (95.8%) of 24 survey respondents agreed that the conference achieved all of its goals, and all agreed it was worth implementing. CONCLUSIONS: This educationally based HP/MG conference supplements existing rotations, didactic presentations, and consensus case conferences and enhances MG education in HP without excessive time commitment or need for extensive in-house MG testing. It also contributes to enhancing HP knowledge among the MG faculty and fellows.

OBJECTIVES: Given the increased complexity of molecular and cytogenetic testing (MOL-CG), the Society for Hematopathology Education Committee (SH-EC) was interested in determining what the current expectations are for MOL-CG education in hematopathology (HP) fellowship training. METHODS: The SH-EC sent a questionnaire to HP fellowship program directors (HP-PDs) covering MOL-CG training curricula, test menus, faculty background, teaching, and sign-out roles. These findings were explored via a panel-based discussion at the 2018 SH-EC meeting for HP-PDs. RESULTS: HP fellows are expected to understand basic principles, nomenclature, and indications for and limitations of testing. Interpretation of common assays is within that scope, but not necessarily proficiency in technical troubleshooting of testing or analysis of complex raw data. CONCLUSIONS: The consensus was that HP fellows should understand the components of MOL-CG testing necessary to incorporate those results into an accurate, clinically relevant, and integrated HP report.

OBJECTIVES: The biannual Fellow In-Service Hematopathology Examination (FISHE) assesses knowledge in five content areas. We examined the relationship between taking the FISHE and performance on it with outcomes on the first attempted American Board of Pathology Hematology subspecialty certifying examination (ABP-HE). METHODS: The pass rate between the ABP-HE candidates who took the spring FISHE and those who did not were compared. The likelihood of fellows passing the ABP-HE based on their percentiles on the FISHE was also assessed. RESULTS: ABP-HE candidates who took the spring FISHE had a higher pass rate (96.4%) than those who did not (76.1%, P < .001). Spring FISHE performance, including total percentile and percentiles in four of five FISHE content areas, was only a weak predictor of passing the ABP-HE. CONCLUSIONS: Candidates who take the spring FISHE do better on the ABP-HE than those who do not. Most fellows passed the first attempted ABP-HE regardless of FISHE performance. Whether this is due to fellows making use of the FISHE as a self-evaluation tool to help identify and then correct their knowledge deficiencies remains to be determined.

Lymphoplasmacytic infiltrates in the breast, a modified skin appendage, include lymphocytic lobulitis, other nonspecific benign proliferations, and mucosa-associated lymphoid tissue (MALT)-type lymphoma. Distinguishing these entities, all of which may be B-cell rich and may have associated sclerosis, can be difficult. In addition, the proportion that represents IgG4-related disease is unknown, and the similarity of MALT lymphomas to primary cutaneous marginal zone lymphoma is uncertain. To address these questions, the clinical, histologic, and immunohistochemical features of 50 benign and malignant breast lymphoplasmacytic infiltrates (10 lymphocytic lobulitis, 1 granulomatous, 19 not otherwise specified, 20 MALT lymphomas) were evaluated. Compared with the MALT lymphomas, benign cases had a less dense infiltrate (P < .001), fewer but more histologically apparent germinal centers (P < .001), and more marked fibrosis (P < .0001). Greater than 60% B cells were present in 23% (7/30) benign cases versus 75% (15/20) MALT lymphomas (P = .0003). Plasma cells were predominantly IgG+ in 83% (24/29) benign cases and predominantly IgM+ in 73% (14/19) MALT lymphomas (P < .0001). None of the benign cases had greater than 50 IgG4+ plasma cells/high-power field, and only 1 lymphocytic lobulitis case had an IgG4/IgG ratio exceeding 40% and no clinical evidence for extramammary IgG4-related disease. Although there may be some overlapping features, routine histopathology together with limited immunohistochemical stains can distinguish benign from neoplastic lymphoplasmacytic infiltrates in the breast. Despite frequent sclerosis, the breast is not a common site of unrecognized IgG4-related sclerosing disease. Although there are similarities, breast MALT lymphomas can be separated from cutaneous marginal zone lymphoma.
