 Soft tissue hemmorrhages in pinpoint size. 
(Petechiae) 
 Soft tissues hemorrhages larger than 
pinpoint size (Ecchymoses) 
 Appear intraorally because of trauma or 
blood disease (Dyscrasia) 
 Trauma – red to purple lesions
TYPES OF INJURY: 
 Cheek biting 
 Coughing 
 Fellario 
 Trauma from prosthetic appliances 
 Injudicious hygiene procedures 
 Iatrogenic dental procedures
 Blood Dyscrasia 
 Red to purple macules 
 Minor trauma
 Color varies from red to blue to purple. 
 Lesions usually appear in areas 
accessible to trauma, such as: 
 buccal mucosa 
Lateral tongue 
Lips 
Junction of hard and soft palate
 Lesion secondary to blood dyscrasia 
may follow on insignificant trauma 
 Other clinical oral signs of blood 
dyscrasia: 
Gingival enlargement 
Gingivitis 
“Spontaneous” gingival hemorrhage 
Prolonged bleeding after oral surgery 
Loose teeth 
Mucosal ulcers
 Blood disorders 
 Dyscrasia 
 Lupus 
 Pemphigus Vulgaris 
 Lichen Planus 
 Lichenois Reactions
 Removing devices that are causing 
trauma & rechecking the px to make 
sure the lesions have resolved is 
necessary 
 Ice packs/ cold compresses, direct 
pressure 
 Steroids & antibiotic
 Excellent for bruises and hematomas 
 Good to guarded for immune-mediated 
vasculitis conditions 
 Depending upon whether the lesion is 
induced through trauma or wheter it is 
systemic, the prognosis will vary.
