Non-bullous

The adjective 'non-bullous' describes a condition or characteristic that is not characterized by the formation of bullae. Bullae are fluid-filled blisters, typically larger than 0.5 cm in diameter, found on the skin or mucous membranes. Therefore, 'non-bullous' implies the absence of these raised, blister-like formations. The term is frequently encountered in medical contexts, particularly in dermatology, where it helps differentiate between various skin conditions and disease presentations. The presence or absence of bullae can be crucial for diagnosis and treatment. The word emphasizes the lack of a specific symptomatic manifestation - the bullae. Assessment and diagnosis are guided by this physical feature.
