It can be seen in neurogenic atrophy


Target fibers :

:dart: It can be seen in neurogenic atrophy.
:dart:They appear as a centrally located dark staining patch on Gomori’s modified trichrome
best demonstrated by NADH-TRpreparations.

:dart:Characteristically, there is a pale core with no NADH-TR activity, rimmed by a darkly stained ring and surrounded by a more normal staining peripheral zone.

:dart:Substantial variation in fiber diameter with atrophic and hypertrophic fibers typical for neurogenic atrophy is also present in this specimen; these features are usually not seen in central core disease.
