L43.0
Hypertrophic lichen planus
Clinical Classification Guidelines
Medical Intelligence & Overview
Hypertrophic lichen planus is a chronic inflammatory skin condition characterized by thick, raised, and often itchy lesions. It is a variant of lichen planus, an immune-mediated disorder that affects the skin and mucous membranes. The hypertrophic form is distinguished by its noticeably thickened, hyperkeratotic plaques commonly found on the lower extremities. While it shares many features with other types of lichen planus, hypertrophic lichen planus tends to be more persistent and resistant to treatment, often requiring specialized management strategies.
Causes & Symptoms
Clinical Causes: Immune system dysregulation leading to abnormal immune response Genetic predisposition may play a role in susceptibility Potential triggers such as certain medications, dental amalgams, or Hepatitis C infection Stress or psychological factors that can influence immune activity
Key Symptoms: Thickened, hyperkeratotic plaques that are raised and often itchy Lesions typically appear on the shins, ankles, or other lower extremities Lesions may have a reddish or purple hue Persistent patches that can become ulcerated or crusted Itching or discomfort in affected areas Possible scarring or pigmentation changes after healing
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily based on clinical examination by a healthcare provider, who observes the characteristic appearance and distribution of skin lesions. A skin biopsy may be performed to confirm the diagnosis by identifying specific histological features such as acanthosis, hyperkeratosis, and band-like lymphocytic infiltration. Additional tests may include screening for associated conditions like Hepatitis C or other underlying factors that could influence the disease course.
Treatment Protocols: Management of hypertrophic lichen planus involves reducing symptoms, controlling inflammation, and preventing scarring. Treatment options typically include:
