A teenager presents to the emergency department with a jaw mass after 3 months of multiple unsuccessful courses of antibiotics. On physical exam, a mandibular mass was evident with no other significant changes. CT scan showed a soft tissue mass suggestive of a slow-growing tumor and biopsy revealed an ameloblastoma (plexiform type). Surgical excision was performed with later reconstruction and full recovery was achieved six months later.
Jaw masses which fail to respond to antibiotic therapy should trigger imaging investigation, as neoplasms in early stages might be confused with dental abscesses, delaying adequate treatment.
A 17-year-old male teenager, previously healthy, with a smoking habit for the past 5 years, presents to the emergency department with a jaw mass starting 3 months before, associated with a progressive dysphagia for solids, but no history of fever or trouble breathing. He had already been treated twice with antibiotics admitting a dental abscess, with no success. The physical examination revealed a painful mandibular mass of stone consistency on the left side, measuring approximately 7 cm, with no inflammatory signs or adenopathies (Figure 1). He also had poor oral hygiene with multiple dental caries.

Initial ultrasound showed a deep bulky non-pure liquid collection, compatible with an abscess but CT scan eventually revealed a soft tissue mass in the left hemimandible measuring 60x60x40 cm, bone expansion with cortical reduction, without periosteal reaction, suggestive of slow-growing tumor (Figure 2). Incisional biopsy disclosed an ameloblastoma (plexiform type). Left hemimandibulectomy with condyle conservation and reconstruction with microanastomosed free flap of peronium was perfomed. Full recovery with physical therapy was achieved six months after.

Initial stages of jaw tumors usually present with a swelling or mass which can lead to being easily mistaken by infections and treated accordingly at first. Following unresponsive antibiotic therapy, additional investigation with imaging is set in motion, revealing a radiolucent or radiopaque lesion in the jaw and prompting a tissue diagnosis in order to correctly assess the best treatment . A slow growing mandibular mass without gross elevation of the inflammatory parameters should lead to suspect a neoplasm since odontogenic abscesses have a much more exuberant course.
Primary jaw neoplasms are broadly classified into odontogenic and nonodontogenic groups . The incidence of nonodontogenic tumors is twice that of odontogenic ones.
The odontogenic tumors are rare, constituting < 1% of oral tumors and they are classified according to their epithelial, mesenchyme and mixed origin . The unicystic ameloblastoma is a benign odontogenic tumor most frequently found in adolescents but the ameloblastoma (plexiform, desmoplasic, granular, acanthomathous and basaloid) is most common diagnosed in the fourth and fifth decades of live . They are both of epithelial origin but different entities with different incidences and prognosis. Ameloblastoma, although rare, benign and a slow growing tumor is locally aggressive and highly recurrent. Incisional biopsy is the gold standard for histopathologic diagnosis, after which radical surgical intervention with at least 10mm of margin is required for eradication of disease. After the resection, advanced reconstructive procedures are needed to restore the function and form of the jaws . Regarding children, craniofacial growth must be taken into account for the surgical excision and later reconstruction.
Jaw masses which fail to respond to antibiotic therapy should trigger imaging investigation, as neoplasms in early stages might be confused with dental abscesses, delaying adequate treatment. This delay often leads to a much more difficult resection and complex reconstruction techniques due to the size of the tumor.
