Which of the following is false regarding scleroma of larynx?
**Core Concept**
Scleroma of the larynx, also known as rhinoscleroma, is a chronic granulomatous infection caused by the bacterium Klebsiella rhinoscleromatis. It primarily affects the nasal passages and upper respiratory tract but can spread to other areas, including the larynx.
**Why the Correct Answer is Right**
Scleroma of the larynx is characterized by the formation of granulomas, which are collections of immune cells that attempt to wall off the infection. These granulomas can lead to scarring and fibrosis, causing symptoms such as hoarseness, difficulty swallowing, and breathing problems. The infection can also cause the formation of ulcers and fistulas in the affected area.
**Why Each Wrong Option is Incorrect**
**Option A:** Scleroma of the larynx is a type of fungal infection, which is incorrect because it is caused by a bacterium, Klebsiella rhinoscleromatis.
**Option B:** Scleroma of the larynx is typically treated with antibiotics, which is correct. However, we are looking for the false statement.
**Option C:** Scleroma of the larynx is a type of cancer, which is incorrect because it is an infectious disease.
**Clinical Pearl / High-Yield Fact**
Scleroma of the larynx is a rare but serious condition that can be misdiagnosed as other conditions such as laryngeal cancer or tuberculosis. It is essential to consider this diagnosis in patients with chronic hoarseness or difficulty swallowing, especially if they have a history of exposure to Klebsiella rhinoscleromatis.
**Correct Answer:** C. Scleroma of the larynx is a type of cancer.
