Pseudo pelade is synonym of –
**Core Concept**
Pseudo-pelade is a rare, chronic form of cicatricial alopecia characterized by the gradual loss of hair follicles, leading to permanent scarring and atrophy of the scalp. This condition is distinct from other forms of alopecia due to its unique pathophysiology and clinical presentation.
**Why the Correct Answer is Right**
Pseudo-pelade is caused by the gradual destruction of hair follicles, leading to the formation of permanent scars and atrophy of the scalp. The exact mechanism is not fully understood, but it is thought to be related to the abnormal proliferation of collagen and the subsequent destruction of hair follicles. This condition is often associated with the presence of an underlying connective tissue disorder, such as lichen planus or lupus erythematosus.
**Why Each Wrong Option is Incorrect**
* **Option A:** Tinea capitis is a fungal infection of the scalp, which does not cause permanent scarring and atrophy. It is characterized by a sudden onset of hair loss, often accompanied by inflammation and scaling.
* **Option B:** Alopecia areata is an autoimmune disease that causes patchy hair loss, but it does not lead to permanent scarring and atrophy. The hair follicles in alopecia areata are typically preserved and can regrow.
* **Option C:** Central centrifugal cicatricial alopecia (CCCA) is a form of scarring alopecia, but it is distinct from pseudo-pelade due to its different clinical presentation and pathophysiology. CCCA typically affects the central scalp and is characterized by a gradual progression of hair loss.
**Clinical Pearl / High-Yield Fact**
Pseudo-pelade is often difficult to diagnose due to its rarity and nonspecific clinical presentation. A thorough medical history and physical examination, including a scalp biopsy, are essential for diagnosing this condition.
**Correct Answer:** C.
