  		Fig. 1A —65-year-old man with basal cell carcinoma of left temporal region. Axial T1-weighted unenhanced turbo spin-echo (TSE) image shows superficially ulcerated tumor penetrating superficial layer of fascia temporalis (arrow).

  		Fig. 1B —65-year-old man with basal cell carcinoma of left temporal region. Axial T1-weighted contrast-enhanced TSE image shows tumor enhances inhomogeneously.

  		Fig. 1C —65-year-old man with basal cell carcinoma of left temporal region. Coronal T1-weighted image shows that tumor reaches zygomatic bone (arrowheads), but there is uncertainty whether there is infiltration of bone.

  		Fig. 1D —65-year-old man with basal cell carcinoma of left temporal region. Coronal fat-suppressed T1-weighted image shows infiltration of zygomatic bone can be excluded. This finding was confirmed by histology.

  		Fig. 2A —51-year-old man with recurrence of basal cell carcinoma of left nasal region. Axial T1-weighted turbo spin-echo image shows tumor that extends into depth of skin. Thin layer of fatty tissue separates tumor from nasal cartilage. Interruption of continuity of this layer (arrows) suggests tumor infiltration of nasal cartilage.

  		Fig. 2B —51-year-old man with recurrence of basal cell carcinoma of left nasal region. Axial T1-weighted contrast-enhanced fat-suppressed image does not corroborate finding in A. There is no interruption of small layer of fat between tumor and cartilage (arrow).

  		Fig. 2C —51-year-old man with recurrence of basal cell carcinoma of left nasal region. Photomicrograph of stained specimen shows tumor (T) does not reach nasal cartilage (C). (H and E)

  		Fig. 3A —80-year-old man with suspicion of recurrent basal cell carcinoma of left nasal region. Axial T2-weighted turbo spin-echo image shows scar tissue in left nasolabial fold with extension to muscle layer. Surface is excavated, mimicking ulcerated recurrence of tumor (white arrow). MS = maxillary sinus. Black arrow = scar tissue. Star = mimic muscle.

  		Fig. 3B —80-year-old man with suspicion of recurrent basal cell carcinoma of left nasal region. Axial T1-weighted contrast-enhanced fat-suppressed image shows enhancement of superficial region of scar (arrowheads) and lack of enhancement of deeper scar tissue. Histology revealed acute and chronic inflammation of superficial scar layer and no recurrence of basal cell carcinoma.

  		Fig. 4A —54-year-old woman with nodule on left cheek. Axial T1-weighted unenhanced image shows small flat tumor nodule with central erosion (white arrow). Black arrow indicates mimic muscle.

  		Fig. 4B —54-year-old woman with nodule on left cheek. Axial T1-weighted contrast-enhanced image shows moderate enhancement of tumor (box).

  		Fig. 4C —54-year-old woman with nodule on left cheek. Photomicrograph of stained specimen shows close concordance with MR microscopy imaging. Solid arrows = tumor borders, open arrow = ulcerated tumor surface, V = vessels. (H and E)
