# Pilar Cyst of the Dorsal Hand: A Rare Presentation of a Common Cyst

## TL;DR

A rare case of a pilar cyst on the hand highlights the variability in their presentation and diagnostic importance.

## Contribution

Reports a unique case of a pilar cyst in an atypical location on the dorsal hand.

## Key findings

- Pilar cysts can occur in areas with few hair follicles, such as the dorsal hand.
- The case emphasizes the need to consider pilar cysts in differential diagnoses for hand tumors.

## Abstract

Pilar cysts are common benign cysts of follicular origin that typically arise in areas of skin containing dense hair follicles such as the scalp. Here we describe a unique case of a young woman who was found to have a pilar cyst on the dorsum of her hand, a rather atypical location given the relative lack of pilosebaceous units. This case illustrates the variability in pilar cyst presentation and the importance of considering a pilar cyst in the differential diagnosis of a patient presenting with a tumor of the dorsal hand.
