Sarcoidosis, an inflammatory disease, involves the skin in about 25% of patients. The most common lesions are erythema nodosum, plaques, maculopapular eruptions, subcutaneous nodules, and lupus pernio. Treatment is not required, since the lesions usually resolve spontaneously in two to four weeks.
Here is a list of dermatologic disorders on Wikipedia that would benefit from additional clinical images. Amelanotic melanoma - a single image of a canine lesion; Pemphigus vulgaris - single clinical image; Bullous pemphigoid- single clinical image; Urticarial vasculitis- no clinical images; Chloracne- single image (not very helpful)
The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3] Within the latter type, the hairs occur in structures called pilosebaceous units , each with hair follicle , sebaceous gland , and associated arrector pili muscle. [ 4 ]
Image-guided radiation therapy is a form of external beam radiotherapy where the patient is positioned with the organs to be treated accurately matched in position to the treatment field, to reduce the dose to nearby organs which are not being treated. Many organs inside the body move by millimeters relative to the external skin surfaces, and a ...
Incisional biopsies can include the whole lesion (excisional), part of a lesion, or part of the affected skin plus part of the normal skin (to show the interface between normal and abnormal skin). Incisional biopsy often yield better diagnosis for deep pannicular skin diseases and more subcutaneous tissue can be obtained than a punch biopsy.
SPECT image (bone tracer) of a mouse MIP Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1]
Images are typically retrieved via wireless data transfer to an external receiver. [27] Augmented reality. The endoscopic images can be combined with other image sources to provide the surgeon with additional information. For instance, the position of an anatomical structure or tumor might be shown in the endoscopic video. [28] Image enhancement
Many diseases cause sweat gland dysfunction: Acromegaly, a result of excess growth hormone, causes the size of sweat glands increase, which leads to thicker skin. [71] Aquagenic wrinkling of the palms, in which white papules develop on the palms after exposure to water, can sometimes come with abnormal aquaporin 5 in the sweat glands. [72]
