If you find some submucosal bleeding points of varying sizes, it may be caused by various bleeding disorders or vitamin C deficiency. If there is mucosal congestion and swelling, and accompanied by bleeding points, it is called mucosal rash, mostly symmetrical, seen in scarlet fever, rubella, or certain drug poisoning.

Differential diagnosis

The symptoms of diffuse hyperemia of the oral mucosa caused by various diseases are mostly similar. At this time, it should be combined with other symptoms of the body and the combination of various tests to identify.

Vitamin C deficiency: Scurvy is a chronic disease caused by long-term lack of vitamin C (ascorbic acid, ascorbic acid). It is rare now, but in northern pastoral areas where vegetables and fruits are absent, or in urban and rural areas. Feeding children neglect complementary food supplements, especially in remote rural areas, still causing morbidity due to improper feeding. Since Pauling published the relationship between cold and vitamin C in 1970, the problems related to the function of vitamin C in the body and the high-dose clinical application have attracted the attention of many scholars.

Mucosal rash: The rash is reddish at the beginning of the rash, gradually dark red or bronze, not painful, itchy, rashes of different sizes, large numbers, symmetric distribution, isolated and scattered, mostly occurring in the chest, abdomen, torso and Back, but the face rarely happens. Patients with weak and malnourished can develop syphilitic pustules, often accompanied by high fever and systemic symptoms.

Foot and Mouth Disease (Foot and Mouth Disease), also known as aphthora fever, is a viral sexually transmitted disease that invades ungulates such as cattle, sheep and pigs. Very harmful to livestock. Occasionally, it is transmitted to people and causes illness.

Scarlet fever: Searlet fever is an acute respiratory infection caused by group A hemolytic streptococcal infection. Its clinical features are fever, angina, diffuse red rash of the whole body and obvious desquamation after rash. A small number of patients develop heart, kidney and joint damage due to allergies after illness.
