PRACTICAL DERMOSCOPY Slow-Growing Pink Papule

  • Published 2018 in

Abstract

Dermoscopy revealed a well-defined, erythematous-pink tumor (Fig. 2A) with prominent, more or less evenly distributed blood vessels, with characteristic cherry blossom images mostly at the periphery of the tumor (Fig. 2B), and pale pink structureless areas (Fig. 2A). With a suspected diagnosis of eccrine poroma, the lesion was excised and the histological findings confirmed the diagnosis. Eccrine poroma is an adnexal tumor derived from the intraepidermal eccrine duct or acrosyringium. It is typically located on the palms, soles, or fingers. Pigmented variants have been reported; clinically and dermoscopically these can mimic a pigmented basal cell carcinoma or malignant melanocytic lesion. The differential diagnosis of the nonpigmented variant includes basal cell carcinoma, squamous cell carcinoma, and hypoor amelanocytic melanoma. A number of dermoscopic patterns and structures have been associated with this tumor, almost all of them referring to the vessels in the lesions: glomerular vessels, hairpin vessels, and linear irregular vessels. Some authors draw attention to the presence of a whitish halo around these vessels, as occurs in keratinizing lesions, but which, in this
