What is the name of the painful pretibial lesion associated with coccidiomycosis?

The painful pretibial lesion associated with coccidioidomycosis is known as erythema nodosum. This condition presents as painful, red nodules typically located on the anterior aspect of the legs, particularly around the pretibial area. Erythema nodosum is a form of panniculitis, which is inflammation of the fat layer under the skin, often in response to systemic infections, including coccidioidomycosis, among other causes.

Coccidioidomycosis, also known as Valley Fever, can lead to hypersensitivity reactions that manifest as erythema nodosum, making it a relevant clinical finding in affected patients. The appearance of these lesions can indicate the body's immune response to the fungal infection, serving as a key clinical sign in the evaluation of this disease.

In contrast, while ulcers, pustules, and fissures can be associated with various skin conditions and infections, they do not specifically identify the distinct presentation of lesions in coccidioidomycosis. Ulcers typically involve deeper skin layers and often result from underlying vascular or infectious processes, pustules are raised lesions filled with pus and generally indicate a bacterial infection, and fissures are cracks that occur in the skin
