Abstract
Wischnewski spots were first described as a common finding in gastric mucosa of decedents exposed to hypothermic environmental conditions. In recent literature, they were also reported in cases of diabetic ketoacidosis, pancreatitis, and fatal burns. Although Wischnewski spots are not specific to cases of hypothermia, we present a case that further supports this contention. We report a case of a middle-aged woman with type 2 diabetes who died of complications of hyperosmolar hyperglycemic state. Although there were no features of hypothermia, she presented with Wischnewski spots in the gastric mucosa. On histology, the gastric mucosa contained brown-black pigmentations with no neutrophilic infiltration. Biochemical analysis from vitreous humor and femoral blood showed marked elevation of glucose levels, low concentration of ketone bodies, pseudohyponatremia, and prerenal azotemia. The autopsy findings in this case discussion shed light to the possible genesis and pathophysiology of Wischnewski spots and highlight an additional differential diagnosis for these lesions.
