This is the oral pathology case of a purple asymptomatic "bump" on the lower gums of a 74-year-old female patient. Clinical assessment reveals a 3 x 3 mm soft, fluctuant nodule located on the lower attached gingiva between teeth Nos. 27 and 28.
Presentation and patient history
A 74-yr-old female presented with the complaint of an asymptomatic “bump” on her lower gums (figures 1 and 2). The patient stated that the lesion had been present for 10 months. A previous general dentist had referred her to an endodontist who performed root canal treatment on her tooth. At that time, the endodontist lanced the lesion and a clear fluid came out. He then placed the patient on a prescription of the antibiotic amoxicillin. However, the papule did not disappear and became darker. The patient presented to a dermatologist for further evaluation.
Physical examination revealed a 3 x 3 mm purple papule located on the lower attached gingiva between teeth Nos. 27 and 28. Palpation revealed a soft, fluctuant nodule that was asymptomatic to the touch.
