Rapid Dermoscopic Changes in Nodular Melanoma

Dermoscopic evaluation of nodular melanoma.

IMPORTANCE Nodular melanoma (NM) is a rapidly progressing potentially lethal skin tumor for which early diagnosis is critical. OBJECTIVE To determine the dermoscopy features of NM. DESIGN Eighty-three cases of NM, 134 of invasive non-NM, 115 of nodular benign melanocytic tumors, and 135 of nodular nonmelanocytic tumors were scored for dermoscopy features using modified and previously descri...

Dermoscopic features of difficult melanoma.

BACKGROUND The dermoscopic diagnosis of cutaneous melanoma (CM) may be difficult because some CM lack specific dermoscopic features for melanoma diagnosis. OBJECTIVE To evaluate whether a diagnosis of CM could be achieved using the classic dermoscopic melanoma-specific criteria, we conducted a retrospective multicenter study of 508 CM samples. METHODS All the dermoscopic images were analyze...

Dermoscopic characteristics of nodular squamous cell carcinoma and keratoacanthoma

BACKGROUND Nodular squamous cell carcinoma (SCC) and keratoacanthoma (KA) may mimic a variety of other benign and malignant non-pigmented nodules. OBJECTIVES To analyze the dermoscopic characteristics of nodular SCC and KA. PATIENTS/METHODS Retrospective analysis of 50 nodular SCCs and 8 KAs collected from a tertiary dermatology referral center and a private dermatology practice in Melbourn...
