ICD-10: L14

The ICD-10 code L14 refers to "Bullous disorders in diseases classified elsewhere." This classification is part of the broader category of skin and subcutaneous tissue diseases, specifically addressing conditions characterized by the formation of blisters (bullae) that arise due to various underlying diseases.

Clinical Description

Definition of Bullous Disorders

Bullous disorders are conditions that lead to the development of fluid-filled blisters on the skin. These blisters can vary in size and may be caused by a range of factors, including autoimmune diseases, infections, genetic disorders, and other systemic conditions. The presence of bullae can indicate significant underlying pathology, necessitating thorough clinical evaluation.

Common Causes

Bullous disorders classified under L14 may arise from various diseases, including but not limited to:

• Autoimmune Diseases: Conditions such as pemphigus vulgaris and bullous pemphigoid, where the immune system mistakenly attacks the skin, leading to blister formation.
• Infectious Diseases: Certain infections, such as herpes simplex virus or staphylococcal infections, can cause blistering.
• Genetic Disorders: Conditions like epidermolysis bullosa, which is characterized by fragile skin that blisters easily.
• Dermatological Reactions: Allergic reactions or irritant contact dermatitis can also lead to blistering.

Symptoms

Patients with bullous disorders may present with:

• Fluid-Filled Blisters: These can be tense or flaccid, depending on the underlying cause.
• Erythema: Surrounding redness may be present, indicating inflammation.
• Itching or Pain: Blisters can be itchy or painful, affecting the patient's quality of life.
