Dermoscopic features of mucinous carcinoma of the skin.

ABSTRACT

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