Pyogenic granuloma associated with guided tissue regeneration: a case report.
A pyogenic granuloma is an exuberant growth of granulation tissue secondary to irritation. Intraorally, it can present with a wide array of clinical appearances, ranging from a sessile lesion to an elevated mass. Pyogenic granulomas generally are soft, painless, and deep red to reddish-purple in color. They are usually 0.5 to 1.0 cm in diameter, more common in females, and often found on the keratinized tissue. This case is interesting because the pyogenic granuloma was found associated with guided tissue regeneration and the lingual alveolar mucosa. The lesion arose after demineralized freeze dried bone allograft and an expanded polytetrafluoroethylene (ePTFE) membrane were utilized to repair osseous defects. Five weeks after surgery, the patient presented for routine follow-up where suppuration associated with the membrane was noted along with an exophytic growth of the lingual alveolar mucosa. The ePTFE membrane was removed alone with an excisional biopsy of one of the growths. By 10 days after the removal of ePTFE, the lesion spontaneously healed. Histologic evaluation of the tissue was consistent with a pyogenic granuloma. This is the first case in the literature of a pyogenic granuloma associated with a routine guided tissue regenerative surgery using a non-resorbable membrane and allograft.
