History
The disorder appears to have made a sudden appearance with a case of light sensitive seborrhoeid in 1957, which  is said to be the first nearest description of the condition. By 1964, the condition in adults became popularly known as perioral dermatitis, but without clear clinical criteria. In 1970, the condition was recognised in children. That all rashes around the mouth are perioral dermatitis has since been frequently debated. That this condition should be renamed periorificial dermatitis has been proposed. Darrell Wilkinson, 1919–2009, was a British dermatologist who gave one of the earliest definitive descriptions of perioral dermatitis and noted that the condition was not always associated with the use of fluoridated steroid creams. Signs and symptoms
A stinging and burning sensation with rash is often felt and noticed, but itching is less common. Often the rash is steroid responsive, initially improving with application of topical steroid. The redness caused by perioral dermatitis has been associated with variable level of depression and anxiety.Initially, there may be small pinpoint papules either side of the nostrils. Multiple small (1-2mm) papules and pustules then occur around the mouth, nose and sometimes cheeks. The area of skin directly adjacent to the lips, also called the vermillion border, is spared and looks normal. There may be some mild background redness and occasional scale. These areas of skin are felt to be drier and therefore there is a tendency to moisturise them more frequently.
Autoimmune polyendocrine syndromes (APS) occur when more than one autoimmune disease occurs in endocrine glands. These syndromes are also called Polyendocrine Autoimmune Disorders. In Type 3, autoimmune thyroiditis and another endocrine autoimmune disease are present, but the adrenal cortex is not involved. References
