Acrokeratosis paraneoplastica with hepatoid adenocarcinoma of the lung : a rare case report

Background acrokeratosis paraneoplastica, also known as Bazex syndrome, is a rare acral psoriasiform dermatosis closely associated with squamous cell carcinoma, especially in the upper respiratory and gastrointestinal tracts. Case presentation : in this case, we will discuss the case of a patient presenting with chronic palmoplantar keratoderma with psoriasiform appearance revealing a hepatoid adenocarcinoma of the lung. Conclusions only a few cases of Bazex's paraneoplastic acrokeratosis have been published, and they are frequently associated with squamous cell carcinoma of the upper aerodigestive tract. The association with this histological variety, hepatoid adenocarcinoma, has never been reported.
