Presentation
Frequent bleeding from a gingival lesion.
Patient Data
Sessile to slightly elevated red mass of the left posterior mandibular gingiva between the 2nd premolar and the 1st molar.
The MRI sequences demonstrate a small soft tissue mass measuring 21 x 13 x 8 mm of the left posterior mandibular gingiva, isointense to the muscles on T1, slightly hyperintense on T2 with vivid homogeneous enhancement following IV contrast. It shows an extension to the interdental gingiva.
No adjacent mandibular lesion is seen.
Case Discussion
A pyogenic granuloma, also known as lobular capillary hemangioma, is a common benign vascular lesion found arising from the skin and mucous membranes.
Oral pyogenic granuloma commonly involves the gingiva 1. Also, it can occur on the lips, gums, cheeks, palate, buccal mucosa, nose, face, nails, and limbs.
Pyogenic granulomas most commonly arise secondary to a prior injury (chronic irritation and/or minor trauma), although spontaneous occurrence is also seen, as is growth within a capillary malformation.
