Merkel cell carcinoma presenting as a nasal dorsum mass: A case report and literature review

Figure 1 Two different angles of the nasal dorsum mass, showing a large 3 × 2 cm pedunculated mass with a wide base over the nasal dorsum (middle 1/3) that was purple (reddish blue) in color. A: Left angle; B: Right angle.

Figure 2  Computed tomography scan showing bone involvement of the lesion.

Figure 3 Multiple sequential multiplanar magnetic resonance images of the paranasal sinuses, with IV contrast showing a midline cutaneous pedunculated nasal mass that measured 1. 8 cm × 1.9 cm × 1.9 cm in the maximum axial and cell carcinoma dimensions, respectively. A-B: Heterogenous, predominantly high in T2; C-E: Isointense T1 signal with homogenous contrast enhancement in a post-contrast study.

Figure 4 Nasal dorsum mass before and after surgery. A: A pedunculated mass in the middle third of the nasal dorsum, with the pen marker showing a paramedian forehead flap before surgery; B: The paramedian forehead flap with excised lesion during surgery; C: Closure of the flap on the nasal dorsum and closure of the flap skin after surgery.
