Cutaneous Metastasis from Lung Cancer: A Single-Institution Retrospective Analysis

Cutaneous Metastasis as the First Symptom

“…[1] Lung cancer is considered to be one of the most frequent sources of skin metastasis, especially in males. [2] Here, we reported a case with cutaneous metastases from squamous cell lung cancer.…”

“…The incidence of cutaneous metastasis in lung cancer is approximately 0.2–3.1%. [2] For different histologic types of lung cancer, discrepancies in the frequency of skin metastasis could be found. Some literatures reported that the most common histologic type causing skin metastasis was adenocarcinoma, while others reported that it could be squamous cell carcinoma, just like this case.…”

“…They were often covered with normal skin, and other clinical appearances included ulcerated, vasculitic, erysipeloides, and bullous forms. [123] Cutaneous metastases from internal malignancy can be located anywhere on the skin, especially in a region near the primary tumor. However, Chiu et al .…”

“…This interesting feature might be related to the rich blood flow and high temperature in the head. [23] Furthermore, other frequent sites of skin lesions include chest wall, back, abdomen wall, and extremities. In this case, the skin nodules with varied size could be seen on the face, lower limbs, right back, and fingertip.…”

Scalp Metastasis as the First Sign of Small-Cell Lung Cancer: Management and Literature Review

“…15 Skin metastasis from lung cancer is a rare clinical entity that has been reported to occur in 0.22% to 12% of patients with lung cancer. [1][2][3][4]6,10,[15][16][17] In most cases, metastases occur after the initial diagnosis and treatment of the primary lung tumor. 17 Skin metastasis as the initial manifestation of an underlying lung cancer is a very rare occurrence.…”
