Mycosis fungoidesThis glossary term has not yet been described.

Even if being a neoplastic disease, mycosis fungoides is listed in this article as a major differential diagnosisThis glossary term has not yet been described. from several inflammatory skin disorders. In particular, differentiation between chronic dermatitisThis glossary term has not yet been described. and early stage mycosis fungoides is often highly problematic. In dermoscopical studies, significant differences have been shown: In contrast to the dotted vesselstiny pinpoint vessels flat melanocytic lesions inflammatory diseases Bowen disease in dermatitis, mycosis fungoides reveal short linear vesselsLinear mildly curved vessels considered irregular when different sizes shapes and curves with a haphazard or random distribution are presented and considered regular when short and fine (thin) linear vessels prevail various diagnoses and orange-yellowish areas. In addition, in mycosis fungoides a peculiar vascular structure is frequently observed consisting of a dotted and a linear component (spermatozoon-like structure). In the assessment of a chronic lesion previously diagnosed as dermatitis, dermoscopic examination is expected to reveal dotted vessels, occasionally combined with yellowish scales. Lesions under long-term treatment with topical steroids represent the only exception to this rule. When, instead, dermoscopy reveals linear vessels, the suspicion of mycosis fungoides rises strongly and in this case, patient’s managementThis glossary term has not yet been described. should be adjusted accordingly.[1]
