A 7-year-old male patient, in good general condition, presented for a painful right lower genian mandibular tumefaction with inflamed skin persisting for more than 1 month. On palpation, the swelling was indurated and difficult to mobilize in deep planes. The patient had multiple mobile cervical lymphadenopathies in the jugulocarotid and spinal chains.

Intraoral examination revealed an ill-defined vestibular redness facing the erupting right mandibular first molar (46), which was painful to percussion. On probing, a distal pocket of 8 ml in depth was noted.

The panoramic radiograph (Figure 1A) was featureless. CT scan revealed a well-limited hypodense image without a condensation line, facing the vestibular side of the (46) and destroying the vestibular table from the outset (Figure 1C–E). The multilamellar periosteal reaction was also noted (Figure 1B). Narrow window sections (Figure 1F,G) revealed thickening of the masseter muscle and a partial thickening of the buccinator. Radioclinical confrontations were in favor of a potentially aggressive lesion. Biopsy confirmed the diagnosis of a vegetable foreign body inflammatory granuloma (Figure 1H). The treatment was the removal of the skin lesion with bone cavity curettage. The evolution was favorable.

The current case presents an uncommon oral disorder, known as foreign-body reaction, resulting from the implantation of food vegetable particles.¹ This rare clinical entity has received several nomenclatures, of which hyaline ring granuloma is the most current. According to the literature, it manifests in several areas, including the lung, gastrointestinal tract, and oral cavity. Women are less affected than men, with the highest incidence in adults. The mandible is more affected than the maxilla. This pathology is mostly reported in edentulous patients with prostheses. It is associated with odontogenic cyst walls, extraction sockets, deep periodontal pockets, and partially erupted teeth as in the present case.¹ We, herein, reported an unusual oral osseous lesion in a child with clinical and radiographic features possibly leading to misdiagnosis and inadequate treatment, including an excessively aggressive approach.² Once aware of this disorder, clinicians may prevent it, provide the proper diagnosis, and indicate the appropriate treatment.
