Paraneoplastic Dermatoses - Bazex Syndrome.

Hello everybody,

So to continue our series on cutaneous manifestations of internal malignancies
Let's quickly learn about Bazex Syndrome.

Bazex syndrome — acrokeratosis
paraneoplastica is a paraneoplastic phenomenon associated with squamous cell carcinoma of the upper digestive tract.

Presents more commonly in Males and over the age of 40.

Presentation: Erythematous to violaceous psoriasiform plaques predominantly located in acral areas (especially the fingers, toes, nose, and helices).

Nail dystrophy, palmoplantar keratoderma, and alopecia are common.

In most patients, manifestations of Bazex syndrome precede the diagnosis of malignancy or the malignancy is diagnosed concurrently.

The lesions of Bazex syndrome are usually resistant to targeted therapies, but treatment of the neoplasm usually leads to resolution of the cutaneous findings, although not always.

Let's learn together!
