A 70-year-old man had painless, non-itchy nodules and plaques on the right side of his trunk for one month, which gradually increased in number and coalesced. He did not report systemic symptoms, comorbidities or medication use. Physical examination revealed firm, nonulcerated, red nodules and plaques on the right anterior trunk in a zosteriform distribution, crossing the T3-T8 dermal midline. Hard, mobile, nontender lymph nodes were palpated in the right inguinal region and right axilla. Possible diagnoses included shingles, skin malignancy, and inflammatory dermatoses. Histopathology showed clusters of epithelioid cells in the dermis with nuclear atypia; immunohistochemistry was positive for CKPan, CDX2 and CK20, negative for CK7. These findings confirmed skin metastases from a primary colorectal tumor. Computed tomography with contrast showed segmental changes.
