Acantholysis is the loss of intercellular connections, such as desmosomes, resulting in loss of cohesion between keratinocytes, [1] seen in diseases such as pemphigus vulgaris. [2] It is absent in bullous pemphigoid , making it useful for differential diagnosis .
Grover's disease (GD) is a polymorphic, pruritic, papulovesicular dermatosis characterized histologically by acantholysis [2]: 529 with or without dyskeratosis. [3] Once confirmed, most cases of Grover's disease last six to twelve months, which is why it was originally called "transient". However it may last much longer.
Canthotomy (also called lateral canthotomy and canthotomy with cantholysis) is a surgical procedure where the lateral canthus, or corner, of the eye is cut to relieve the fluid pressure inside or behind the eye, known as intraocular pressure (IOC). [1]
Image at right shows influx of inflammatory cells including eosinophils and neutrophils in the dermis (solid arrow) and blister cavity (dashed arrows), and deposition of fibrin (asterisks). [15] However, the diagnosis of bullous pemphigoid consist of at least 2 positive results out of 3 criteria: [19] Pruritus and/or predominant cutaneous blisters
Clinically, mild glycogenic acanthosis is a normal finding, and does not progress to esophageal cancer or to stricture. [4] It is not related to leukoplakia, and is not dysplastic or premalignant. It was originally thought to be associated with gastroesophageal reflux disease (GERD), but the association is not entirely clear. [ 2 ]
Histologic image showing a section of epidermis. Stratum spinosum labeled slightly below center. The stratum spinosum (or spinous layer/prickle cell layer) [1] is a layer of the epidermis found between the stratum granulosum and stratum basale. [2]
Acanthocytes, from peripheral blood, under light microscopy. Note the irregularly shaped, non-circular cells in the image. Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections.
Early actinic keratosis with parakeratosis, with black arrows indicating one of multiple retained nuclei in the stratum corneum. Parakeratosis is a mode of keratinization characterized by the retention of nuclei in the stratum corneum. [1]
