is usually more abundant than in condyloma acuminatum.
Labrador Retrievers can suffer from hereditary nasal parakeratosis
However, according to some authors, large numbers of neutrophils in parakeratosis
in the viable epidermis or neutrophils forming intraepidermal collections, as well as more numerous extravasated erythrocytes in the epidermis and necrosis more emphasized in the upper part of the epidermis, are features more common in HFMD (24), which was also present in our case to some extent.

, epidermal hyperplasia, absence of granular layer, accumulation of neutrophil in Malpighian layer, elongation of rete ridges and dilated capillaries in superficial dermis 2.
Histopathology showed hyperkeratosis, parakeratosis
, elongation of rete ridges and mild perivascular mononuclear infiltrate.
Histopathologic findings revealed parakeratosis
, acanthosis cell layer thickening, irregular elongation of rete ridges, dilated dermal blood vessels, and perivascular lymphomonocytic infiltration in the dermis [Figure 1]d.
or zinc deficiency disease in the pig.
In PLEVA, focal parakeratosis
and crusting is present.
Histopathology: The histopathological features are unique and specific for porokeratosis, the presentation of invagination which is a parakeratosis
column, the presentation of coronoid lamella--closely packed parakeratotic cells in thin column, which presented along the course of the most upper layer (stratum corneum).
Different levels of parakeratosis
and acanthosis may be seen in all the diseases.
The histological findings of skin biopsy are frequently non-characteristic thinning of the granular layer and stratum corneum, psoriasiform hyperplasia and less common compact parakeratosis
with large nuclei, subcorneum or intracorneum splitting, presence of clear cells in the upper epidermis or stratum corneum, dyskeratosis, dermal infiltrate with neutrophils and/or eosinophils and dilated blood vessels in the superficial dermis (6).
