title: Psoriasiform dermatitis in a case of newly diagnosed locally advanced pyriform sinus tumour: Bazex syndrome revisited.
abstract: Acrokeratosis paraneoplastica of Bazex is a rare but important paraneoplastic dermatosis, usually manifesting as psoriasiform rashes over the acral sites. It often precedes diagnosis of the associated malignancy, usually that of upper aerodigestive tract squamous cell carcinoma. We present the case of a patient with a newly diagnosed pyriform sinus tumour and associated acrokeratosis paraneoplastica. To the best of our knowledge, this is the first reported case in the local literature.
