Relationship of red splenic arteriolar hyaline with rapid death: a clinicopathological study of 82 autopsy cases

Abstract

Abstract Background Little is known about the relationship between splenic arteriolar hyaline and cause of death. The purpose of this retrospective study was to evaluate the clinicopathological significance of splenic arteriolar hyaline in autopsy cases and estimate the applicability of hyaline for diagnosing the cause and rapidity of death. Methods Archival data and histological slides from 82 cases were reviewed retrospectively. One section of each spleen was evaluated microscopically. The tinctorial pattern of splenic arteriolar hyaline was examined with Heidenhain’s Azan trichrome stain, and the relationships between this pattern and age, cause of death, and rapidity of death were investigated. Results Fifty-four cases demonstrated hyaline change, with 3 different tinctorial patterns: red, blue, and a combination of red and blue. The 3 patterns coexisted in various proportions in each tissue section. Frequency of the blue pattern increased with age (P P Conclusions Estimation of splenic arteriolar hyaline with Heidenhain’s Azan trichrome stain is useful for assessment of the cause and rapidity of death.
