A 64-year-old man had noticed a tumor in his upper lip, which gradually enlarged for approximately 30 years. The biopsy specimen suggested malignancy and therefore he was introduced to us for surgery. Physical examination revealed the soft tumor on his upper lip (Fig. 1). Blood count, biochemical tests and serous tumor markers such as ot-fetopro-tein (AFP), carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), prostate-specific antigen (PSA) and squamous cell carcinoma (SCC) were within normal limits. No lymph node swelling was palpable. Gallium and bone scintigraphy or systemic computed tomography did not show any evidence of malignant tumors.
