The Case of the Hemorrhagic Gingival Mass

Case Challenge Number: 6

Diagnostic Information

Clinical Findings Clinical examination revealed a non-tender, bright-red pedunculated mass which arose from the buccal interdental papilla between teeth #19 and #20. (Figure 1) The mass tended to bleed easily upon manipulation. Generalized marginal gingivitis was seen throughout the mouth.

Bitewing Radiograph

A bitewing radiograph revealed slight bone loss at the crest of the alveolar bone between #19 and #20. (Figure 2) However, no obvious intrabony lesion was observed.

Additional Clinical History

During the review of the patient’s medical history, she stated she currently was five months pregnant.

Photomicrographs

Because the large size of the lesion was creating problems with eating and speaking, it was decided to excise the mass and submit it to the Oral Pathology Laboratory. Microscopic examination showed an ulcerated mass of granulation tissue that was covered by a thick fibrinopurulent membrane. (Figure 3)

This tissue was characterized by numerous capillaries which were engorged with red blood cells. (Figure 4)

There was an associated mixed inflammatory infiltrate which included polymorphonuclear leukocytes, lymphocytes, and plasma cells. (Figure 5)
