Petechia of the lower leg in a person with platelets of 3 due to ITP (immune thrombocytopenia).The most common cause of petechiae is through physical trauma such as a hard bout of coughing, holding breath, vomiting, or crying, which can result in facial petechiae, especially around the eyes.
Herpetic gingivostomatitis is an infection caused by the herpes simplex virus (HSV). The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.
Palatal petechiae. Petechiae on the soft palate are mainly associated with streptococcal pharyngitis, [6] and as such it is an uncommon but highly specific finding. [7] 10 to 30 percent of palatal petechiae cases are estimated to be caused by suction, which can be habitual or secondary to fellatio. [8]
In about 50% of cases, small reddish-purple spots called petechiae can be seen on the roof of the mouth. [26] Palatal enanthem can also occur, but is relatively uncommon. [16] A small minority of people spontaneously present a rash, usually on the arms or trunk, which can be macular (morbilliform) or papular. [16]
The cause is not completely understood, but it is thought that the condition represents a T cell mediated immune response which is triggered by a variety of factors. The individual ulcers (aphthae) recur periodically and heal completely, although in the more severe forms, new ulcers may appear in other parts of the mouth before the old ones ...
Denture-related stomatitis is a common condition where mild inflammation and redness of the oral mucous membrane occurs beneath a denture.In about 90% of cases, Candida species are involved, [4] which are normally a harmless component of the oral microbiota in many people.
A diagnosis can be made from clinical signs and symptoms, and treatment consists of minimizing the discomfort of symptoms. [5] It can be differentiated from herpetic gingivostomatitis by the positioning of vesicles - in herpangina, they are typically found on the posterior oropharynx, as compared to gingivostomatitis where they are typically found on the anterior oropharynx and the mouth.
Due to the strong association with denture-wearing, the lesion tends to occur more in adults than children. There is no gender predilection. [1] In people who wear dentures 24 hours a day, its incidence is around 20%. Inflammatory papillary hyperplasia almost exclusively involves the hard palate, specifically the vault of the palate.
