Synchronous oral cavity malignancy in identical twins-unusual coincidence of similarities

Abstract:
The multifactorial nature of head and neck squamous cell carcinoma (HNSCC) has led to increased efforts in establishing various risk factors. Well-known environmental risk factors for HNSCC include tobacco use, heavy alcohol consumption, immunosuppression, and more recently human papillomavirus infection. Familial clustering has been observed in cancers occurring at other sites, but not so much with oral squamous cell carcinoma (OSCC) without exposure to shared environmental risk factors. An unusual case of identical twins who presented with OSCC involving an identical site and exhibiting similar histological features is reported here. The two patients underwent identical surgery with curative intent, culminating in good outcomes. It appears that no other cases of identical twins with a similar presentation in time, anatomical site, and histopathology have been reported in the literature.
