Summary
Cutaneous metastases can mimic herpes zoster, appearing in a dermatomal pattern. Skin biopsy is crucial for diagnosing these rare metastatic skin lesions and differentiating them from infections.
Area of Science:
- Oncology
- Dermatology
- Pathology
Background:
- Cutaneous metastases are observed in 2.5% to 5% of patients with malignant disease.
- The occurrence of skin metastases often correlates with the prevalence of specific malignancies in each sex.
- Malignant disease can present with unusual cutaneous manifestations.
Observation:
- Two cases of cutaneous malignancy presented in a dermatomal distribution.
- These presentations mimicked herpes zoster (shingles).
- Zosteriform eruptions require a broad differential diagnosis.
Findings:
- Metastatic disease can occur in a dermatomal pattern.
- The pathogenesis of metastatic disease in a dermatomal distribution warrants discussion.
- Differential diagnosis for zosteriform eruptions should include malignancy.
Implications:
- Skin biopsy is essential for accurate diagnosis of zosteriform eruptions.
- Early diagnosis of cutaneous metastases can impact patient management.
- Understanding rare presentations of cancer aids clinical practice.
