What Is Fungal Acne?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Fungal acne, also known as Malassezia folliculitis, is a skin condition that is often mistaken for traditional acne. Unlike bacterial acne, which is primarily caused by the bacterium Cutibacterium acnes, fungal acne is caused by an overgrowth of yeast from the Malassezia genus. This condition can be challenging to diagnose and treat due to its similarity to bacterial acne.

Causes

Fungal acne is caused by an overgrowth of Malassezia yeast, which is a normal part of the skin’s microbiome. Factors that can contribute to this overgrowth include a warm and humid environment, excessive sweating, and the use of oily skin products. The yeast thrives in these conditions, leading to an infection of the hair follicles1 2.

Symptoms

The symptoms of fungal acne are similar to those of bacterial acne, which can make it difficult to distinguish between the two. Common symptoms include:

• Small, uniform red bumps that are often itchy
• Pustules that resemble acne
• Clusters of pimples that appear on the chest, back, and shoulders
• Skin irritation and inflammation1 3.

Diagnosis

Diagnosing fungal acne can be challenging due to its resemblance to bacterial acne. Dermatologists often rely on a combination of clinical examination and laboratory tests to confirm the diagnosis. A skin scraping or biopsy may be performed to identify the presence of Malassezia yeast. Additionally, a KOH (potassium hydroxide) test can be used to detect fungal elements in the skin sample3 4.

Pathophysiology

The pathophysiology of fungal acne involves the colonization of hair follicles by Malassezia yeast. This yeast feeds on the sebum produced by the sebaceous glands, leading to an inflammatory response. The inflammation results in the formation of pustules and papules, which are characteristic of fungal acne. Unlike bacterial acne, which is driven by the proliferation of Cutibacterium acnes, fungal acne is primarily a result of yeast overgrowth1 2 4.

Conclusion

Fungal acne is a common but often misdiagnosed skin condition caused by the overgrowth of Malassezia yeast. It presents with symptoms similar to bacterial acne, making accurate diagnosis crucial for effective treatment. Understanding the causes, symptoms, and pathophysiology of fungal acne can help in distinguishing it from other types of acne and managing it appropriately.
