Phlyctenula is a term derived from the Greek word "phlyktein" meaning "to blister" or "to form small blisters". It refers to a small blister-like lesion or nodule that appears on the skin or mucous membranes. These lesions are commonly associated with certain skin or eye conditions and are typically characterized by their reddish color and elevated appearance.
In dermatology, phlyctenula refers to a specific skin condition known as phlyctenular keratoconjunctivitis. This condition primarily affects the eyes and is often caused by an allergic reaction or an infection, particularly tuberculosis. It is characterized by the formation of painful, raised nodules or blisters on the conjunctiva, cornea, or eyelids. Phlyctenular keratoconjunctivitis can lead to symptoms such as eye redness, itching, burning sensation, tearing, and sensitivity to light.
In some cases, the term "phlyctenula" is also used in pathology to denote a small blister-like lesion that appears in certain diseases or medical conditions. These lesions can occur on various parts of the body, including the skin, mucous membranes, or even internal organs. The term may be used to describe the appearance of such lesions in different medical contexts.
Overall, whether in dermatology or pathology, phlyctenula refers to a small blister-like lesion or nodule that can occur in various conditions, typically involving the skin, mucous membranes, or eyes.
