What does hypergranulosis mean?
Hypergranulosis means an increased number of cells in the granular layer of the skin. The granular layer is found near the surface in a part of the skin called the epidermis. Hypergranulosis is a non-cancerous change. The granular layer is a normal part of the skin and is usually 1 to 2 cells thick.
What is Hypogranulosis?
Hypogranulosis. Epidermis is thin over dermal papillae (thinned suprapapillary plates) Regular acanthosis, often with clubbed rete ridges. Relatively little spongiosis. Dilated capillaries in dermal papillae.
What is epidermal acanthosis?
Acanthosis. Acanthosis is a thickening of the epidermis and elongation of the rete ridges due to thickening of the spinous layer +/- enlargement of rete pegs.
What is focal Parakeratosis?
Parakeratosis is a mode of keratinization characterized by the retention of nuclei in the stratum corneum. In mucous membranes, parakeratosis is normal. In the skin, this process leads to the abnormal replacement of annular squames with nucleated cells.
What is Psoriasiform hyperplasia?
A nonspecific, histologically defined appearance that consists of regular elongation of rete ridges, suprapapillary thinning, mild spongiosis, telangiectasis of blood vessels in the papillary dermis and fusion of foot processes. Aetiology. Seborrhoeic dermatitis, late secondary syphilis.
What causes perivascular lymphocytic infiltrate?
A prominent perivascular neutrophilic inflammatory cell infiltrate can be associated with neutrophilic urticarial reactions (fig 7A), dermatitis herpetiformis, early IgA dermatosis, early Sweet’s syndrome,26–28 early connective tissue disorders such as lupus erythematosus, early herpetic infection, and acute …
What causes acanthosis?
Acanthosis nigricans skin patches occur when epidermal skin cells begin to reproduce rapidly. This abnormal skin cell growth is most commonly triggered by high levels of insulin in the blood. In rare cases, the increase in skin cells may be caused by medications, cancer, or other medical conditions.
What is hyperplastic epidermis?
Term: epidermal hyperplasia. Definition: overdevelopment or increased size, usually due an increased number of cells in the epidermis.
What deficiencies cause parakeratosis?

- Cryotherapy.
- Oral isotretinoin.
What does hypergranulosis mean for the granular layer?

What are the symptoms of wedge shaped hypergranulosis?
Compact hyperkeratosis and wedge-shaped hypergranulosis that corresponds to the openings of follicles and acrosyringia Irregular epidermal hyperplasia with a sawtooth appearance, and a bandlike, predominantly lymphocytic infiltrate in the superficial dermis that obscures the dermoepidermal junction
Why do I have a lot of congestion in my chest?
