Dermatitis is a term used for different types of skin inflammation, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to covering the entire body. Dermatitis is also called eczema but the same term is often used for the most common type of skin inflammation, atopic dermatitis.
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable.
Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye.
Acral lentiginous melanoma (ALM) is a type of skin cancer. It typically begins as a uniform brownish mark before becoming darker and wider with a blurred, irregular border. ALM is most frequently seen on the foot of a person with darker skin but can also be found in non-sun exposed areas such as the palms, soles, and under finger and toenails. It may become bumpy and ulcerate. When under the nail it typically appears as dark longitudinal streaks. As it grows, ALM may also spread to other areas of the body.
Permanent makeup, also known as permanent cosmetics, derma-pigmentation, micro-pigmentation, semi-permanent makeup and cosmetic tattooing, is a cosmetic technique which employs tattooing techniques to replicate the appearance of traditional makeup. By implanting pigments into the dermis, long-lasting designs are created such as eye liner, eyebrows, and lip color. This procedure appeals to a diverse range of people; from those who want to make their daily routines more simple to individuals with medical conditions. By eliminating the need to apply traditional makeup regularly, permanent makeup has become a very convenient and effective solution. More than an aesthetic technique, permanent makeup plays a crucial role in procedures of reconstructive type.
Allergic contact dermatitis (ACD) is a form of contact dermatitis that is the manifestation of an allergic response caused by contact with a substance; the other type being irritant contact dermatitis (ICD).
Tattoo removal is the process of removing an unwanted tattoo. The process of tattooing generally creates permanent markings in the skin, but people have attempted many methods to try to hide or destroy tattoos.
Tetrazepam is a benzodiazepine derivative with anticonvulsant, anxiolytic, muscle relaxant and slightly hypnotic properties. It was formerly used mainly in Austria, France, Belgium, Germany and Spain to treat muscle spasm, anxiety disorders such as panic attacks, or more rarely to treat depression, premenstrual syndrome or agoraphobia. Tetrazepam has relatively little sedative effect at low doses while still producing useful muscle relaxation and anxiety relief. The Co-ordination Group for Mutual Recognition and Decentralised Procedures-Human endorsed the Pharmacovigilance Risk Assessment Committee (PRAC) recommendation to suspend the marketing authorisations of tetrazepam-containing medicines across the European Union (EU) in April 2013. The European Commission has confirmed the suspension of the marketing authorisations for Tetrazepam in Europe because of cutaneous toxicity, effective from the 1 August 2013.
Tattoo inks consist of pigments combined with a carrier, used in the process of tattooing to create a tattoo in the skin. These inks are also used for permanent makeup, a form of tattoo.
Rosai–Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy or sometimes as Destombes–Rosai–Dorfman disease, is a rare disorder of unknown cause that is characterized by abundant histiocytes in lymph nodes or other locations including the skin, sinuses, brain and heart. Individuals with the disorder often present with enlarged lymph nodes and a nodular red skin rash. The main causes of morbidity with the illness are systemic infection from impaired immune response and organ dysfunction from histiocyte deposition throughout the body.
Amelanotic melanoma is a type of skin cancer in which the cells do not make any melanin. They can be pink, red, purple or of normal skin color, and are therefore difficult to diagnose correctly. They can occur anywhere on the body, just as a typical melanoma can.
Melanocyte protein PMEL also known as premelanosome protein (PMEL), silver locus protein homolog (SILV) or Glycoprotein 100 (gp100), is a protein that in humans is encoded by the PMEL gene. Its gene product may be referred to as PMEL, silver, ME20, gp100 or Pmel17.
Phytophotodermatitis, also known as berloque dermatitis, margarita photodermatitis, lime disease or lime phytodermatitis is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent followed by exposure to ultraviolet A (UV-A) light. Symptoms include erythema, edema, blisters, and delayed hyperpigmentation. Heat and moisture tend to exacerbate the reaction.
Cutaneous amoebiasis, refers to a form of amoebiasis that presents primarily in the skin. It can be caused by Acanthamoeba or Entamoeba histolytica. When associated with Acanthamoeba, it is also known as "cutaneous acanthamoebiasis". Balamuthia mandrillaris can also cause cutaneous amoebiasis, but can prove fatal if the amoeba enters the bloodstream It is characterized by ulcers. Diagnosis of amebiasis cutis calls for high degree of clinical suspicion. This needs to be backed with demonstration of trophozoites from lesions. Unless an early diagnosis can be made such patients can develop significant morbidity.
Granuloma gluteale infantum is a cutaneous condition that appears in the anogenital region of infants as a complication of diaper dermatitis. According to some, no granulomas are found.
Skin cancer, or neoplasia, is the most common type of cancer diagnosed in horses, accounting for 45 to 80% of all cancers diagnosed. Sarcoids are the most common type of skin neoplasm and are the most common type of cancer overall in horses. Squamous-cell carcinoma is the second-most prevalent skin cancer, followed by melanoma. Squamous-cell carcinoma and melanoma usually occur in horses greater than 9-years-old, while sarcoids commonly affect horses 3 to 6 years old. Surgical biopsy is the method of choice for diagnosis of most equine skin cancers, but is contraindicated for cases of sarcoids. Prognosis and treatment effectiveness varies based on type of cancer, degree of local tissue destruction, evidence of spread to other organs (metastasis) and location of the tumor. Not all cancers metastasize and some can be cured or mitigated by surgical removal of the cancerous tissue or through use of chemotherapeutic drugs.
Iodopropynyl Butyl Carbamate (IPBC) is a water-soluble preservative used globally in the paints & coatings, wood preservatives, personal care, and cosmetics industries. IPBC is a member of the carbamate family of biocides. IPBC was invented in the 1970s and has a long history of effective use as an antifungal technology.
The process or technique of tattooing, creating a tattoo, involves the insertion of pigment into the skin's dermis. Traditionally, tattooing often involved rubbing pigment into cuts. Modern tattooing almost always requires the use of a tattoo machine and often procedures and accessories to reduce the risk to human health.
CP-GEP is a non-invasive prediction model for cutaneous melanoma patients that combines clinicopathologic (CP) variables with gene expression profiling (GEP). CP-GEP is able to identify cutaneous melanoma patients at low-risk for nodal metastasis who may forgo the sentinel lymph node biopsy (SLNB) procedure. The CP-GEP model was developed by the Mayo Clinic and SkylineDx BV, and it has been clinically validated in multiple studies.
