Dyskeratotic cells
What is a dyskeratotic cell down the microscope? In the epidermis it is pink because of either early or abnormal keratinisation .Ocassionally a bit of a basophilic nucleus may persist. Unfortunately a variety of other terms are used in describing these cells in different conditions.
Kamino bodies - definitely basement membrane
Civatte bodies - dyskeratotic cells in the upper dermis
Colloid bodies - interface dermatitis, may be basement membrane and immunoglobulin
Cytoid bodies - same as colloid bodies
Corps ronds and Grains - acantholytic dyskeratotic cells seen in Dariers and other acantholytic disorders
Apoptotic, dyskeratotic and necrotic keratinocytes can all look the same!
You come across these terms most in Darier's disease, Lichen planus, Graft versus Host disease, Warty dyskeratoma, Spitz nevi (Kamino bodies) and Incontinentia pigmenti
