Introduction Pityriasis rosea is a common benign skin disease, or exanthema seen in children and adults. It was first described in 1798 by British physician Robert Willan (1757–1812) under the name roseola annulata.(1) In 1860, the French doctor Camille Melchior Gilbert named the exanthema pityriasis rosea.(2) Since then, much was done to describe the rash of pityriasis rosea but much still remains to be discovered regarding its cause and treatment. The more usual annular variety was first described by another French dermatologist Pierre-Antoine-Ernest Bazin in 1862.(3) Jean Baptiste Emile Vidal, another French dermatologist, described pityriasis circiné et marginé in 1882.(2,3) It has fewer and larger lesions, often localized at the axillae or groins, and runs a longer course.(4) The herald patch was first described by a French …show more content…
Between 9% and 16% of patients develop ulcers or plaques in the mouth. It is relatively unusual, however, for patches to appear on the face. A small minority of patients may have the herald patch as the only sign of pityriasis rosea.(6,7,9) Pityriasis rosea is accounting for 3% of visits to dermatologists in the United States and Canada. The overall prevalence of the disease in the general North American population is thought to be about 0.13% in males and 0.14% in females. It is rare in infants and the elderly; most cases are diagnosed in persons between the ages of 10 and 35 years.(10,11) It tends to cluster in families, which is one reason why some researchers have been investigating various viruses as possible causes; however, it is not known to spread by casual

My struggle with acne scars started when I was 14. When my acne started to clear up I began to see multiple small depressions on my face, specifically on my cheeks. I did my research and found out that
Lupus is often hard diagnose because the symptoms mimic other disorders. The most distinctive sign of lupus is a butterfly shaped rash across the cheeks.
This disease is called, facial tumor disease. It can spread just by a single bite. There is still no cure for this disease, but the scientists are still working on it. (“Tasmanian Devil, Sarcophilus harrisii”).
What are these red patches of skin on my body that I can’t ever help from scratching? It is eczema, which is defined as a medical condition in which patches of skin become inflamed, with blisters that cause itching and bleeding. Genetics take a role in the possibility of having eczema, after comes the diagnosis, then being prescribed the treatment needed, and lastly their prognosis.
Other lesions, such as eczema, body lice, insect bites, fungal infections, poison ivy, and various forms of dermatitis can make a person susceptible to this infection.... ... middle of paper ... ... The New York Times.
From 166 A.D. to 180 A.D., The Antonine Plague spread around Europe devastating many countries. This epidemic killed thousands per day and is also known as the modern-day name Smallpox. It is known as one of deadliest plagues around the world.
This parasite is spread through the bite of sandflies. There are three different types of infections and they each show varying degrees of severity. The cutaneous form produces mild skin ulcers, mucocutaneous produces ulcers in the mouth and nose, and the visceral form of the disease starts with skin ulcers and then fever, low red blood cell count, and an enlarged spleen and liver. The parasite is detected by a microscope and visceral can also be found by doing blood tests. 12 million people are in infected in 98 different countries and 2 million new cases are found every year. The disease also kills around 20 to 50 thousand people a year.
...may have the same symptoms. The symptoms are red bumps that may bleed if the sores are picked over.
The initial infection begins with a prodromal phase with characteristic features of pain, itching, paresthesia, dysesthesias (unpleasant sensations), and sensitivity to touch in any of the dermatomes.6In a few days at the affected site, a unilateral rash begins to appear. .The chest being the most common site, followed by face, lesions typically affects the ophthalmic distribution of the trigeminal nerve.6 This rash subsequently becomes into a vesicle, which resolves into a scab .It has been observed that most patients get complete resolution in 4 to 6 weeks6
Histoplasmosis is a type of fungus that lives in the environment, mainly in areas of birds or bats dropping in humid areas. It is not a series condition unless it spreads throughout the body. One can develop this by breathing in spores of fungus in areas with bird or bat droppings. It is usually transmitted through spores becoming airborne by demolition projects. This fungus grows mainly in central southeastern and mid- atlantic states. This fungus thrives in in damp soil and rich organic material. People can still get histoplasmosis again if they previously had it, but he illness would likely be more milder. The reproductive spores of this fungus are extremely light and can float into the air when dirt or any other contaminated material
Impetigo can occur in the bullous and nonbullous forms. Winn et al. (2006) stated it is a highly contagious bacterial infection of the superficial layers of the epidermis. Impetigo is caused by S.aureus in 80-90% of cases and in 10-20% of cases by S.pyogenes (p. 634). Nonbullous impetigo is caused by a host response to the bacterial infection, whereas a staphylococcal toxin causes bullous impetigo (Cole and Gazewood, 2007, p. 859). Nonbullous impetigo is more common and accounts for approximately 70% of reported impetigo diagnoses as described by (Cole and Gazewood, 2007, p. 859). In the same article Cole and Gazewood (2007) go on to describe the pathophysiology of nonbullous impetigo which starts as a single papule or red macule that rapidly turns into a vesicle. The vesicle breaks easily and forms an erosion of skin, soon after the liquid matter dries and forms a characteristic honey-colored crust that may be pus-like (p 859-860). Impetigo seems to be overwhelmingly spread by autoinoculation and tends to affect areas subject to environmental trauma, such as the extremities or the face as seen in the case of the patient described above (Cole and Gazewood, 2007, p. 859-860). In 2003, Brown, Shriner, Schwartz, and Janniger, stated, patients can easily auto inoculate themselves and pass the infection to others after excoriating an infected site. This allows a rapid distribution of infection, especially in places that have a high population of children such as schools and daycare. Children normally are normally infected through contact with other children, but fomites are another infection source as well. When adults are infected, they usually develop impetigo from contact with children or adults but can also contract an infection...
The symptoms of psoriasis differ from type to type, although inflamed, scaly lesions are present in all five types. The most common form of the disease, plaque psoriasis, is identified by small bumps that begin to grow and become scaly. These lesions flake easily, but removing these patches can cause the tender skin below to bleed. In the Guttate type, small, individual, red drops form. This type does not have as much scaling as plaque psoriasis. The drops usually clear up on their own, but may also reappear as a different form of psoriasis, usually plaque. Inverse psoriasis usually occurs in places where the skin folds, such as the genitals, breasts, armpits or the backs of knees. This type will appear red, yet it will be smooth and dry. Also, no scaling will occur. Pustular psoriasis is a type that's significantly more rare. It is also more painful. In this type, blisters filled with non-infectious pus appear within a few hours and then dry up and peel within another two days. Severe medical risks exist for those who have this particular form of psoriasis, due to its side effects; exhaustion, anemia, weight loss, fever, chills, rapid pulse rate, severe itching and muscle weakness. Even less common than pustular psoriasis is erythrodermic psoriasis. This type is...
