Pigmented purpuric dermatosis refers to one of the three major classes of skin conditions characterized by purpuric skin eruptions.

Contents

Pigmented purpuric dermatosis are distinguished from other purpura by size (0.3–1 cm) and are most often seen in the lower extremities. [1] :829 Pigmentary purpuric eruptions may present with one of several clinical patterns. There may be overlapping characteristics among pigmented purpuric dermatosis and between their signs and those of other purpuric eruptions. [1] :829 Examples of the pigmented purpuric dermatosis group include: [1] :829–30

Although vascular damage may be present, it is insufficient for these conditions to be considered forms of vasculitis. [2]

A few very small non-blinded studies of treatment with narrow-band ultraviolet light have been reported as promising. [3]

Pityriasis rosea is a type of skin rash. Classically, it begins with a single red and slightly scaly area known as a "herald patch". This is then followed, days to weeks later, by an eruption of many smaller scaly spots; pinkish with a red edge in people with light skin and greyish in darker skin. About 20% of cases show atypical deviations from this pattern. It usually lasts less than three months and goes away without treatment. Sometimes malaise or a fever may occur before the start of the rash or itchiness, but often there are few other symptoms.

Purpura is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes. They measure 3–10 mm, whereas petechiae measure less than 3 mm, and ecchymoses greater than 1 cm.

<span class="mw-page-title-main">Schamberg disease</span> Medical condition

Schamberg's disease, is a chronic discoloration of the skin found in people of all ages, usually only affecting the feet, legs or thighs or a combination. It may occur as a single event or subsequent bouts may cause further spread. It is most common in males. It is named after Jay Frank Schamberg, who described it in 1901. There is no known cure for this disease but it is not a life-threatening condition and is mainly of cosmetic concern, although, because it can appear so suddenly, so extensively and because it usually leaves permanent discoloration of the skin, it can cause understandable psychological concern. The skin lesions sometimes cause itching, which can be treated by applying cortisone cream. The cortisone cream will only help with the itching and does not improve the discoloration of the skin. Schamberg's disease causes no other symptoms beside skin discoloration and itching. The condition is caused by inflammation of capillaries near the surface of skin and subsequent leaking of red blood cells into surrounding tissues. As the red blood cells break down and get mostly resorbed, some of the iron released by the red blood cells remains in the skin and causes the characteristic rust-colored appearance. The cause of the capillary inflammation is usually unknown.

Gianotti–Crosti syndrome, also known as infantile papular acrodermatitis, papular acrodermatitis of childhood, and papulovesicular acrolocated syndrome, is a reaction of the skin to a viral infection. Hepatitis B virus and Epstein–Barr virus are the most frequently reported pathogens. Other viruses implicated are hepatitis A virus, hepatitis C virus, cytomegalovirus, coxsackievirus, adenovirus, enterovirus, rotavirus, rubella virus, HIV, and parainfluenza virus.

Transient neonatal pustular melanosis (TNPM), also known as pustular melanosis, is a transient rash common in newborns.

The rash usually fades over three to four weeks but may linger for up to three months after birth.[3] It can occur anywhere on the body, including the palms and soles.[1][2][3]

Domenico Majocchi (1849–1929) was an Italian dermatologist ,an histologist and anatomo-pathologist of great value and an extremely expert clinician, who discovered some pathologies such as the purpura annularis telangiectodes and the Fungal folliculitis.

Histopathology of dermatitis can be performed in uncertain cases of inflammatory skin condition that remain uncertain after history and physical examination.
