Wei Zhang et al. Skin Health Dis. .

Abstract

Squamous cell carcinoma of the penis is an uncommon cancer. Vascular feature on dermoscopy is common in all forms of invasive squamous cell carcinoma, and the presence of the specific vascular features is often used to aid diagnosis. Here, we reported a new dermoscopic finding-seaweed-like vascular pattern in squamous cell carcinoma of the penis.

Clinical manifestation, dermoscopic feature, and histological analysis. (a) Clinical manifestation. Red plaque was observed on his penis. (b) Dermoscopic feature. Dermoscopy of the lesion surface showed polymorphous vessels arranged radially in a pattern that resembles floating red seaweed. (c) Histological examination. Atypical squamous cells invading into the dermis, with some keratin pearls and multiple dysmorphic intratumoral vessels (Haematoxylin‐eosin stain; original magnification 10X.).
