Compact orthokeratosis, wedge-shaped hypergranulosis, irregular acanthosis, colloid bodies, flattened rete ridges, liquefactive degeneration of basal layer
, and Max Joseph's space.
In sequence, the cells of the epidermis basal layer
go through a dimorphism, changing from their original cubic form to a cylindrical one, when observing the production of the basal membrane.
Surface-zone (of basal layer
) scales in ventral interciliary field reduced to terminal field (0 = a, 1 = p)
Another finding in our present study was that eIF6 was deficient in the basal layer
of epidermis of proliferative phase and recurrence in regressive phase.
5 and 6) labeled cells were found in the basal layer
of the epithelium as well as in the lepidotriquias escleroblastos.
(1) Staining should be present in the basal layer
with extension upwards to involve at least one-third of the epithelial thickness.
The BCC is a common skin cancer that arises from the cells of the basal layer
of the epithelium or from the external root sheath of the hair follicle.
WT1 expression was detected more in nuclei of cells, however few of the cells showed cytoplasmic expression.WT1 was found weak or absent in the basal layer
and in the infiltrating nest of cells.
Histopathologic examination of hyperpigmented lesions has shown diffuse hypermelanosis of the entire epidermis with no melanin incontinence and a sparse perivascular lymphocytic infiltrate in the dermis in a previous study.4 Similar findings of increased basal layer
pigmentation and lymphocytic infiltrate were noted in this study, but in addition melanophages were also seen in the dermis.
The cells superficial to the basal layer
are polyhedral and often exhibit intracellular edema.
Melanoma is a type of skin cancer that develops in the pigment-producing melanocytes in the basal layer
of the epidermis.
A histopathologic examination of the atrophic pigmented plaques showed thickening of the basal layer
, increased melanin pigmentation, flattening of the dermal papillae, and mild perivascular lymphocytic infiltration (Fig.
