Discolored Toenails? It Might Not Be Fungus! Sorting Out Onychomycosis vs. Psoriasis

June 17, 20242 min read

Discolored, thickened, and crumbly nails can be a cause for concern. But before you jump to conclusions about fungal nails (onychomycosis), there's another player that might be mimicking the culprit: psoriasis. Here at West Haven Foot and Ankle Center, we understand the importance of an accurate diagnosis, and today, we'll delve into the world of differential diagnosis – where we differentiate between onychomycosis and psoriatic nails.

The Similarities: A Case of Mistaken Identity

Both onychomycosis and psoriatic nails can share some unsettling characteristics:

  • Discoloration: Yellow, white, or brown discoloration can plague nails affected by either condition.

  • Thickening: Nails may become abnormally thick and lose their smooth texture.

  • Crumbling: The affected nail plate can become brittle and prone to crumbling or breakage.

These similarities can make it challenging to distinguish between the two at first glance. So, how do we crack the code?

The Multifaceted Approach: Unveiling the Clues

Here at West Haven Foot and Ankle Center, we employ a multifaceted approach to differentiate between onychomycosis and psoriatic nails. This may involve:

  • Detailed history: Discussing your overall health, any previous nail issues, and any family history of psoriasis can provide valuable clues.

  • Thorough examination: Our podiatrists will meticulously examine your nails, looking for specific signs like pitting (tiny depressions) in psoriatic nails or involvement of multiple nails in fungal infections.

  • Diagnostic tests: In some cases, a nail clipping might be sent to a lab for microscopic examination or fungal culture to confirm the presence of fungus.

Why a Proper Diagnosis Matters

Identifying the root cause of your nail woes is crucial for effective treatment. Fungal infections typically require antifungal medications, while psoriatic nails are best managed through a combination of medications and therapies specific to psoriasis.
