A 52-year-old female patient presented with facial injury suspicious for nasal bone fracture. During facial bone computed tomography (CT), a well-circumscribed cystic lesion was discovered incidentally on right side of the mandible (). The patient did not complain of any discomfort, pain, or numbness of the lower face. She also denied any trauma to the chin or significant surgical history.\nLateral radiographs showed a well-defined, radiolucent, ovoid lesion anterior to the right mandibular angle (). The coronal and sagittal CT images demonstrated a deficiency in the mandibular defect containing the soft tissue lesion in continuity with the submandibular gland (). Based on the radiological findings, the patient was diagnosed with a Stafne bone cavity, and regular observation was recommended.
Two well demarcated ovoid radiolucent lesions (right, 3.9×1.5 cm and left, 2.9×1.1 cm) were found incidentally in the anterior mandible of a 44-year-old female patient on her panoramic dental X-ray (). The patient did not show any symptom of radiolucencies. The radiological findings were interpreted as radicular cysts. Two fragments of tissue from the cavities were submitted for histological diagnosis. The biopsied tissue fragments showed normal salivary gland tissue with mixed serous and mucinous cells. These findings were otherwise unremarkable, except for the small amount of lymphoid cell infiltration that was discovered (). The clinical, radiological, and pathological findings were consistent with Stafne bone cavity.
