The MF lesions were assessed dermoscopically. CD34 immunohistochemistry was performed to count dermal microvessel density (MVD). <b><i>Results:</i></b> The total dermal MVD was significantly higher in MF patients (19.77 ± 5.81) than in controls (4.44 ± 3.16; p = 0.013). Among them, there were 10.8 ± 4.1 sprouts of endothelial buds (clusters of cells per field) in patients and 2.4 ± 2 in controls (p = 0.000). The dotted pattern of blood vessels was the most frequently encountered pattern in the MF lesions by dermoscopy. <b><i>Conclusions:</i></b> Our findings support that neoangiogenesis is significantly increased in early MF lesions and that the main dermoscopic feature of MF is dotted blood vessels. 2015-06-03 00:00:00 Angiogenesis Dermoscopy CD34 Mycosis fungoides
