Clinical and dermoscopic findings of cutaneous metastases: a case series

Dermoscopy and high‐frequency ultrasound provide diagnostic clues in a gastric adenocarcinoma with cutaneous metastasis as the initial presentation: A case report

“…4 These vascular structures within a cutaneous nodule should be regarded as an important clue for cutaneous metastasis. 5 However, it is worth noting that in the case of cutaneous metastases from gastric adenocarcinoma, the density of vessels tends to be lower and significant dilation may not occur, which could be a characteristic feature specific to this type of metastasis. On the other hand, cutaneous sarcoidosis can exhibit two distinctive dermoscopic structures: either focally distributed or diffuse structureless orange or yellowish-orange areas and well-focused linear or branching vessels.…”
