# Multiple, Segmental, Non-Syndromic Basal Cell Carcinomas—Clinical, Dermoscopic and Histopathological Features

## TL;DR

A 72-year-old woman had four non-melanotic skin tumors confirmed as basal cell carcinomas with unique dermoscopic features.

## Contribution

This is the first report describing dermoscopic features of segmental/agminated basal cell carcinoma.

## Key findings

- Four amelanotic tumors on the left arm were confirmed as basal cell carcinomas via histopathology.
- Dermoscopy revealed polymorphic and arborizing vessels with non-specific malignant features.
- No recurrence was observed during a 3-year follow-up period.

## Abstract

We present a case of a 72-year-old woman with four amelanotic tumors on the left arm, without a history of skin cancer or sun exposure. Dermoscopy showed polymorphic and arborizing vessels, with some lesions displaying non-specific malignant features. Histopathology confirmed basal cell carcinoma (BCC) in all lesions. No signs of recurrence were observed during 3-year follow-up. Segmental/agminated basal cell carcinoma is a rare differential diagnosis of multiple clustered, painless pink tumors. To the best of our knowledge, this is the first report describing their dermoscopic features.
