Bazex's syndrome (acrokeratosis paraneoplastica)—first case report of association with a bladder carcinoma

Bazex's acrokeratosis paraneoplastica is a clinically well‐defined entity consisting of a distal erythematosquamous eruption and nail dystrophy. It is always associated with neoplasia, mainly squamous carcinomas of the upper digestive and respiratory tracts; therefore, Bazek's acrokeratosis is considered to be a specific marker of internal malignancy. Two new cases of this syndrome are reported. The first was in a 41–year‐old man with a squamous cell carcinoma of the oesophagus, the second in a 73–year‐old man who presented with a transitional cell bladder carcinoma, an association not previously reported.
