ABSTRACT
Betel quid chewing is a common practice in many cultures and has been associated with various health risks, including an increased likelihood of developing squamous cell carcinoma (SCC). This case study presents a critical instance of metastatic SCC of the lower lip induced by betel quid chewing. A 45-year-old male with a history of betel quid chewing presented with a persistent and enlarging sore on his lower lip. A biopsy revealed SCC, and subsequent imaging confirmed metastasis to the lungs. This case highlights the potential for betel quid chewing to induce metastatic SCC and emphasizes the need for awareness and cessation of this habit to prevent such severe health outcomes. The aggressive nature of metastatic SCC warrants immediate and effective treatment strategies.
