Milky red globules / areas
Although milky red globules are not seen frequently, when present, they are highly suggestive of invasive melanoma . They may be valuable in the recognition of thicker amelanotic/hypomelanotic melanoma (AHM), which often do not have many noticeable or identifying features. In AHM, milky red globules/red areas were reported in 31% of thin melanomas (1mm) and in 93.3% of thick melanomas (1mm), as compared with 17.3% and 9.1% of amelanotic /hypomelanotic benign melanocytic lesions and amelanotic/hypomelanotic non-melanocytic lesions, respectively. In another study, 4.7% of melanomas with vascular structures on dermoscopy contained milky red globules/areas, correlating with a PPV of 77.8%; only 0.5% of nonmelanoma lesions had these structures. Vascular blush, also known as erythematous blush, pink veil, or milky red areas, represents a red or pink region that corresponds to an area with increased vascularity. Thus, vascular blush can be seen in lesions, such as dermatofibromas, vascular tumors, such as pyogenic granulomas, inflammatory lesions, and both melanoma and nonmelanoma skin cancers. Although vascular blush can be seen in nevi, it tends to be more common and conspicuous in melanoma.
