Background: Oral myiasis is a rare parasitic infestation primarily affecting vulnerable individuals with poor hygiene or underlying psychiatric illness. Chronic inflammation associated with prolonged infestation may create a microenvironment conducive to malignant transformation. Case Presentation: We report a rare case of a 40-year-old male with longstanding psychosis who presented with severe oral myiasis in the upper anterior gingivobuccal sulcus. Mechanical removal of larvae and debridement were performed, followed by incisional biopsy. Histopathological examination revealed intraoral basal cell carcinoma, an exceptionally uncommon malignancy in this location. Conclusion: This case highlights the potential association between chronic parasitic infestation and carcinogenesis in neglected psychiatric patients. Early detection, routine oral screening, and integrated multidisciplinary care are essential to prevent advanced presentations and improve outcomes.
