RESUMO
BACKGROUND: Peripheral giant cell granuloma (PGCG) is an uncommon pathology that affects gingival or alveolar mucosa. Although PGCG can be associated with dental implants, little is known about this lesion and implant osseointegration as well as its etiopathogenesis and the treatments available. This study sought to report a rare case of PGCG associated with dental implant, emphasizing its clinical and histopathological aspects. CASE PRESENTATION: A 53-year-old man had an exophytic, reddish lesion, around a crown attached to a dental implant located in the left mandible. Radiographically, there was bone loss around the implant. After excisional biopsy, histological examination revealed a submucosal proliferation of multinucleated giant cells rendering the diagnosis of peripheral giant cell granuloma. Patient has been under follow-up for 6 months with no recurrence. CONCLUSIONS: Peri-implant lesions must be completely removed to prevent recurrence of PGCG and implant failure, even in cases suspected to be reactive. Besides, histological examination must be performed on all peri-implant reactions to achieve the appropriate diagnosis and, consequently, the best treatment and follow up.

Some malignant neoplasias induce the appearance of local or systemic manifestations at distant sites, which can act as indicators of their presence in a process named paraneoplastic syndrome. Granulomatous reactions have already been described related to malignancies. This report describes a case of synchronous orofacial granulomatosis and mucoepidermoid carcinoma and discusses the significance of this association.

Rhinoliths are calcified masses formed within the nasal cavity because of the solidification of mucus, debris, or foreign objects by gradual accretion of mineral salts. They are mostly asymptomatic and incidentally diagnosed, although some patients may complain of nasal discharge and obstruction. Ulceration of the nasal mucosa, facial swelling, and bone destruction are less frequently observed but bring about difficulties for differential diagnoses with several pathologic entities. This article presents a case of a 54-year-old woman with a rhinolith causing palatal perforation, focusing on the diagnostic process and histopathologic characteristics.
