Common terms:
*Acanthosis = thickening of the prickle layer (stratum spinosum) of epidermis.<ref>[http://dictionary.reference.com/browse/acanthosis http://dictionary.reference.com/browse/acanthosis]</ref>
{| class="wikitable sortable"
*Acantholysis = loss of intercellular connections in the epidermis.
! Term
*Dyskeratosis = abnormal keratinization, often refers to keratinization below the stratum granulosum; keratinization above may be abnormal (dependent on body site).
! Meaning
*Parakeratosis = retention of nuclei in the stratum corneum, normal in mucous membranes.
! Reference
*Spongiosis = epidermal intercellular edema;<ref>{{Ref PBoD|1230}}</ref> cells appear to have a clear halo around 'em.
