Studies comparing the prognostic role of RUNX1 mutations (RUNX1mut) in acute myeloid leukemia (AML) and acute myeloid leukemia-with myelodysplasia-related changes (AML-MRC) are limited. Our study examines the genetic profile of 118 RUNX1mut AML patients including 57 AML with RUNX1mut and 61 AML-MRC with RUNX1mut and 100 AML, NOS patients with wild type RUNX1 (RUNX1wt). Results revealed that AML-MRC patients with RUNX1mut had shorter median overall survival (OS) (11 ± 3.3 months) when compared to AML with RUNX1mut (19 ± 7.1 months) and AML, NOS with RUNX1wt (not reached) (p = .001). The most common concurrent mutations observed in AML-MRC with RUNX1mut patients were DNMT3A, SRSF2, ASXL1, and IDH2 while in AML with RUNX1mut patients were ASXL1, SRSF2, TET2, IDH2, and DNMT3A. ASXL1 and TET2 mutations appeared to adversely affect OS in AML-MRC, but not in AML with RUNX1mut. Concurrent RUNX1/DNMT3A mutations, in contrast had negative impact on OS in AML with RUNX1mut, but not in AML-MRC with RUNX1mut.

BACKGROUND: Lichenoid granulomatous dermatitis (LGD) is an uncommon reaction pattern for which clinical correlates can be difficult to establish. LGD combines vacuolar degeneration with variable types of granulomas. OBJECTIVE: To determine clinical correlates of LGD. METHODS: The laboratory information systems at the University of Florida, the Medical College of Wisconsin, and Inform Diagnostics Research Institute were queried to identify 56 cases of LGD. Cases were reviewed for information regarding eosinophils, plasma cells, deep perivascular infiltrates, granuloma subtype, parakeratosis, epidermal atrophy, psoriasiform epidermal changes, pseudoepitheliomatous hyperplasia, periadnexal inflammation, vasculitis, and red blood cell extravasation. RESULTS: The most common clinical correlates were drug eruption (39.3%, n = 22) and lichenoid keratosis (19.6%, n = 11). Tattoo reaction, postherpetic dermatitis, and scabies or postscabietic dermatitis each accounted for 7.1% (n = 4) of cases. Pigmented purpuric dermatosis and lichen striatus each accounted for 5.4% (n = 3) of cases. Dermal eosinophils (P = .005) and psoriasiform epidermal changes (P = .055) were associated with drug hypersensitivity. Perineural (P = .049) and perifollicular (P = .003) inflammation were associated with tattoo reaction and postherpetic dermatitis. Red blood cell extravasation was helpful in cases of pigmented purpuric dermatosis (P = .049). LIMITATIONS: This study is limited by its retrospective nature and statistical power. CONCLUSION: Dermal eosinophilia, psoriasiform epidermal changes, periadnexal inflammation, and red blood cell extravasation might aid in the clinical diagnosis of patients with LGD.

AIM: The objective of this study was to define the rates of discrepancy between outside pathological diagnoses and secondary reviews. MATERIALS AND METHODS: We assessed the rates of discordance between outside diagnoses and secondary reviews, categorizing by organ site and minor or major (affecting patient care) discordances. RESULTS: A total of 9,289 consecutive surgical pathology (SP) and cytopathology (CP) cases reviewed in 2015 were identified. For 8,191 outside SP cases reviewed, the overall discordance rate (DR) was 14.2% (2.2% major, 12.0% minor). Specifically, neuropathology had the highest DR (10.9%), cutaneous and breast the lowest (1.1% each). Among 1,098 CP cases, the total DR was 13.7% (3.0% major, 10.7% minor). The majority of CP cases (1,066) were non-gynecological and had a total DR of 13.4% (2.7% major, 10.7% minor). CONCLUSION: While major DR was low, certain subspecialties had high DRs. This project can help identify areas where focused education could help improve pathological diagnostic accuracy for cancer.
