Atlas of Dermoscopy; 2nd edition. Dermoscopy improves the recognition of benign-malignant compound tumors. Dotted vessels are defined as tiny red dots densely aligned next to each other in a more or less regular fashion.
D, Dermatofibroma pattern 10 or atypical with polymorphous, atypical vessels linear-irregular vessels, telangiectasias, and dotted vessels. Cutaneous amelanotic melanoma metastasis and dermatofibromas showing a dotted vascular pattern. Clinical data were obtained for each patient, including age, sex, and anatomical location of the specimen.
We appreciated a yellowish homogeneous area in 4. The histopathologic examination revealed an aneurysmatic dermatofibroma. Posteriormente, Puig y cols. Angiokeratomas are benign vascular lesions that histopathologically consist of dilated subepidermal vessels and, in most cases, are associated with an epidermal reaction that includes acanthosis or hyperkeratosis.
