# Linear Leucoderma Following Intralesional Steroid Injection

## TL;DR

A 23-year-old woman developed linear leukoderma, a rare skin condition, after receiving an intralesional steroid injection for a ganglion cyst.

## Contribution

The paper presents a rare case of linear leukoderma following a single intralesional steroid injection.

## Key findings

- Linear leukoderma occurred three months after a single intralesional steroid injection.
- The depigmentation was localized to the volar aspect of the left forearm.
- The case highlights the potential for rare complications despite localized steroid use.

## Abstract

Intralesional steroid injections avoid potential side effects associated with systemic administration, such as hypothalamus-pituitary-adrenal axis suppression, endocrine changes, allergic reactions, syncope, and blindness, but do not spare local side effects, such as pain, hemorrhage, ulceration, atrophy, hypopigmentation, calcification, secondary infection, granuloma formation, and allergic reaction. Linear leukoderma following intralesional steroid is a rare but known complication. Here, we report a case of a 23-year-old female presented with cutaneous linear depigmentation along the volar aspect of her left forearm developed three months following a single episode of injection triamcinolone acetonide for ganglion cyst.
