I just came across this interesting article published in the Indian Journal of Dermatology, Venereology and Leprology about appearances in Dermatopathology. Dermatopathologists give different terms to describe various morphological appearances of different lesions so as to help them identify them. Although most of the terms I read were known to me, I came across new terms that I have not known before:

Antler like/ Stag horn appearance: Downgrowth of elongated rete ridges with pigmentation at the tips in Dowling Degos disease

Camel foot appearance: Regular acanthosis with elongated rete ridges seen in psoriasis

Flame-thrower-like appearance: Telogen hair in vertical section showing irregular shaggy border and lined with esinophilic trichilemmal keratin

Owl's eyes appearance of verruca plana: Koilocytes with peri-nuclear halos in verruca plana

Picket fence appearance of the granular deposits of IgA and C3 in DH

Ravelled wool appearance: The abnormal elastic fibres in PXE forming a tangled mass resembling woolen threads

Septate tomato appearance: Epidermal invagination and numerous eosinophilic viral inclusion bodies of molluscum contagiosum resembling a septate tomato on scanning view

Tri-layered (Stripped) appearance of LSEA

Dermatopathologists are really cool!!!

This is the article citation in case anyone is interested in further reading:
