Dermoscopic features of mucinous carcinoma of the skin.
BACKGROUND
Dermoscopic features of nonpigmented skin lesions are seldom reported; dermoscopy might be useful in speculating pathologic features in the upper dermis.


OBJECTIVE
The objective was to identify additional dermoscopic criteria.


METHODS
Dermoscopy of the mucinous carcinoma of the skin occurring on the cheek of a 69-year-old man was performed.


RESULTS
We have shown characteristic dermoscopic features of whitish network and light-brown globules and they correspond to the pathologic findings of fibrous septum and mucinous deposition, respectively.


CONCLUSIONS
Dermoscopic examination seemed useful as an adjunct to the diagnosis of this rare nonpigmented malignant neoplasm.
