Plasmacytoid Myoepithelioma of the Hard Palate: Surgical Excision with PRF-Assisted Healing and A Custom Stent : A Case Report
摘要
To present a rare plasmacytoid myoepithelioma of the hard palate managed with surgical excision, PRF and custom palatal stent.
Clinical PresentationA 48-year-old male presented with a slow-growing, asymptomatic, 3.0 × 2.0 × 1.5 cm firm palatal nodule.
InterventionCBCT revealed soft-tissue mass with slight bone erosion. Preoperative neurological examination was normal. Complete Surgical excision under general anesthesia was performed due to severe gag reflex and need for airway protection. The primary treatment included surgical excision with adequate tumor margins, sacrificing the greater palatine neurovascular bundle via ligation and cauterization for adequate tumor margins, and PRF as an adjunctive suportive healing measure stabilized in place by a custom stent.
OutcomeImmunohistochemistry (CK7+, SOX10+, S100 patchy positive, Calponin-, p63-, SMA-) confirmed benign plasmacytoid myoepithelioma. Patchy S100 is characteristic of this variant. Healing was uneventful. Expected palatal numbness occurred without functional impact. No recurrence at 6 months.
ConclusionPlasmacytoid myoepithelioma requires comprehensive assessment including neurological examination and patient counseling regarding potential nerve sacrifice. Combined PRF-stent protocol is a great adjunctive that optimizes healing. Bundle sacrifice for adequate margins is acceptable with minimal functional consequences.
