A Case of Zosteriform Cutaneous Metastasis from Lung Cancer / 대한피부과학회지

ABSTRACT

Cutaneous metastasis is a relatively rare complication of internal malignancy and has been reported in 0.7% to 9% of all malignant cancers. It may be an important clue for undiagnosed malignancies or even the prognosis of primary cancers. Cutaneous metastatic cancers vary in type and are rarely presented with zosteriform distribution. The lung is one of the most common primary sites of zosteriform cutaneous metastasis. We describe a 52-year-old man with a prior history of lung cancer in whom zosteriform cutaneous metastasis developed along the right T4-5 dermatome on his trunk. This case highlights the importance of the differential diagnosis of cutaneous metastasis with zosteriform distribution and the need of skin biopsy in order to confirm the early diagnosis.
