Inclusion Terms
- Lassueur Graham-Little Piccardi syndrome
Medical Intelligence & Overview
Other lichen planopilaris, classified under ICD-10 code L66.19, is a specific form of a skin condition that affects the scalp and leads to hair loss. It is part of a group of inflammatory skin disorders known as lichenoid conditions, which can cause scarring and permanent hair loss if not appropriately managed. This condition is associated with a rare syndrome called Lassueur Graham-Little Piccardi syndrome, characterized by a combination of scalp hair loss, non-scarring hair loss in other areas, and skin changes in other parts of the body. Understanding the key features of this disorder can help in recognizing its presentation and potential impact.
Causes & Symptoms
Clinical Causes: Autoimmune response where the immune system mistakenly attacks hair follicles Genetic predisposition in some cases Environmental triggers such as certain medications or allergens Possible links to other lichenoid skin conditions
Key Symptoms: Gradual thinning or patchy hair loss on the scalp Inflammation, redness, or scaling on affected areas of the scalp Presence of small, shiny, or scarred patches on the scalp Possible hair loss in other areas such as the eyebrows or body hair Skin changes like hyperpigmentation or erythema in affected regions In some cases, itching or burning sensations on the scalp
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of clinical examination, medical history, and laboratory tests. A scalp biopsy may be performed to confirm the presence of lichenoid tissue reaction and tissue scarring characteristic of lichen planopilaris. Dermoscopy, a non-invasive skin imaging technique, can also aid in identifying specific features such as perifollicular scaling and loss of follicular openings. Differential diagnosis should exclude other causes of hair loss, including alopecia areata and other scarring alopecias.
Treatment Protocols: While there is no cure for lichen planopilaris, several treatment options aim to reduce inflammation, slow progression, and minimize scarring. These may include:
