Sažetak

Desmoplastic neurotropic melanoma (DNM) is a rare melanoma
subtype that shows tropism for the nerves, perineural invasion correlates to
higher rate of local recurrence, poorer prognosis and worse morbidity. Given
the paucity of typical melanoma features, both clinical and pathological, this
confusing skin cancer may act as a pretender, thus leading clinician to misdiagnosis
and subsequent inappropriate conservative treatment. Sarcomatoid-
like cells rearrangement and absence of pigmentation can lead towards
sarcoma diagnosis, so specific skills are required to pathologist to properly recognize
this melanoma subtype. In this case report, we present an example of
how challenging can be the diagnosis, and how it can affect clinical outcome
