Fig. 1. Histologically, colliquation necroses
are observed, mainly in the
white brain substance of corpus
medularis, appearing as brighter foci,
extensively vacuolized and with a reticular
structure. H/E, Bar = 30 µm.

of muscle fibres (waxy degeneration).
Swol len homogeneous muscle
fibres, having lost their striated pattern,
with increased eosinophilia.
Centrally, necrobiotic lesions resulting
in muscle cell degradation (Zenker’s
necrosis). H/E, Bar = 25 µm.
