Bottom Line: The mass was a solid tumor associated with resorption of surrounding bone and expansion of the greater palatine canal.The histopathological diagnosis was a suspected malignant neurogenic tumor.No recurrence was noted 29 months after the operation.

ABSTRACT
The patient was an 84-year-old man who was referred to our hospital in mid-December 2012 for a close examination of a mass arising from the left side of the hard palate that was found by a local dentist. The initial examination revealed the presence of a 3.0-cm elastic soft, dome-shaped mass in the left hard palate. CE-CT showed a lesion of size 1.8 × 1.4 cm in the right hard palate, which extended upward and invaded the nasal cavity. The mass was a solid tumor associated with resorption of surrounding bone and expansion of the greater palatine canal. CE-MRI indicated that the mass extended upward and invaded the nasal cavity, and the mass showed hypointensity on T1-weighted images, hyperintensity on T2-weighted images, and an irregular margin with internal enhancement. Abnormal uptake of FDG on PET-CT (SUVmax = 5.2) was observed in the left hard palate. The biopsy site lesion rapidly increased in size and biopsy was performed again in January 2013 due to suspicion of a malignant tumor. The histopathological diagnosis was a suspected malignant neurogenic tumor. Therefore, the patient underwent partial maxillectomy and a split-thickness skin graft in late February 2013. No recurrence was noted 29 months after the operation.

Mentions: Initial oral findings showed a 3.0-cm elastic soft, dome-shaped mass in the right hard palate (Figure 1). CE-CT showed a lesion of size 1.8 × 1.4 cm in the right hard palate, which extended upward and invaded the nasal cavity (Figure 2(a)). The mass was a solid tumor associated with resorption of surrounding bone and an enlarged greater palatine canal (Figure 2(b)). CE-MRI indicated that the mass extended upward and invaded the nasal cavity, and the mass showed hypointensity on T1-weighted images, hyperintensity on T2-weighted images, and an irregular margin with internal enhancement (Figure 3(a)). Dynamic MRI revealed a plateau type lesion that was suspected to be a malignant tumor (Figure 3(b)). Abnormal uptake of FDG in PET-CT (SUVmax = 5.2) was observed in the left hard palate (Figure 4). Based on these findings, the patient was diagnosed with a malignant tumor in the left hard palate.
