A 64‐year‐old man was admitted with complaints of abdominal pain and pollakisuria. A soft mass was palpable under his navel. Magnetic resonance imaging (MRI) revealed a 9 × 6 cm tumor, which was composed of a cystic lesion arising from the urachus and a solid mass component at the urinary bladder dome. Urine cytology specimens showed squamous cell carcinoma (SCC). Serum SCC level was increased and the tumor was removed surgically. Histological examination detected well‐differentiated SCC, which had invaded the urinary bladder and the peritoneum. The patient has been followed up without recurrence for 6 months.
