Labial pyogenic granuloma related to trauma: A case report and mini-review

This paper reports a case of a labial pyogenic granuloma in the lower lip of a 15-year-old boy due to chronic trauma from the maxillary left central incisor. The case report is based on the CARE (CAse REport) Checklist developed by the Joanna Briggs Institute. A further aim is to present a mini-review about the link between labial pyogenic granuloma and trauma, through searching in three databases (MEDLINE, EMBASE, and Global Health) using a predefined search strategy and keywords. The Cochrane Library and PROSPERO were also searched for published and ongoing systematic reviews, respectively. Only five case reports were found that discussed the link between labial pyogenic granuloma and trauma. Chronic trauma was found to be the most common cause of pyogenic granuloma affecting the lip. Excisional biopsy was the preferable treatment due to the advantage of allowing histopathologic assessment, which is necessary to establish a definitive diagnosis. Dentists advise to include labial pyogenic granuloma in their differential diagnosis (ie, mucocele, cyst, abscess, hematoma, minor salivary gland trauma or tumor) when assessing lesions in the upper and lower lips, in particular when related to a history of trauma.
