Case presentation

A 56-year-old white woman who had previously been healthy had been admitted to hospital 6 months previously for 2 months due to fever for 1 week associated with an onset of pain in her left hemithorax. She was initially treated for community-acquired pneumonia with a respiratory quinolone and continued to experience pain, which was worse during expiration. She lost 8 kg over the period of her admittance and developed plaque and papules. A chest X-ray showed opacity with fairly precise limits in the lower third of the left hemithorax similar to a Hampton hump, which consists of a shallow wedge-shaped opacity in the periphery of the lung with its base against the pleural surface, associated with diaphragmatic clamping (figure 1A–C).
