L66.0
Pseudopelade
Clinical Classification Guidelines
Medical Intelligence & Overview
Pseudopelade, also known as 'false baldness,' is a condition characterized by the gradual loss of hair, resulting in smooth, scar-free patches on the scalp. This form of hair loss can resemble true cicatricial alopecia but differs because it does not involve scarring or inflammation. Often affecting women more than men, pseudopelade can be a distressing dermatological issue that impacts self-esteem and quality of life.
Causes & Symptoms
Clinical Causes: Progressive hair follicle destruction without inflammation Unknown exact trigger, but possibly linked to underlying dermatological or autoimmune conditions History of scalp trauma or surgery Genetic predisposition in some cases Possible association with other types of alopecia, like androgenetic alopecia
Key Symptoms: Gradual appearance of small, smooth, hairless patches on the scalp Scar-free and without signs of inflammation or redness Painless process, often noticed over months or years Patchy hair loss that enlarges slowly Absence of itching or burning sensations
Diagnostic & Treatment
Diagnosis Path: Diagnosis primarily relies on clinical examination of scalp patches that show hair loss without scarring or inflammation. Dermatologists may use a combination of patient history, visual assessment, and laboratory tests such as scalp biopsies to differentiate pseudopelade from other causes of alopecia. Dermoscopy, a non-invasive skin imaging technique, can also assist in evaluation, revealing characteristic features of hair loss patterns. It’s essential to rule out other conditions like cicatricial alopecia, which do involve scarring.
Treatment Protocols: There is no universally effective treatment for pseudopelade. Management strategies focus on slowing or halting hair loss and addressing any underlying factors. These options include:
