What's your diagnosis? The patient doesn't have endocarditis, cyanotic heart disease, bronchial carcinoma, bronchiectasis, a lung abscess or empyema, fibrosing alveolitis, hepatic cirrhosis or IBD. He does have painful fingers. I'll post the correct answer in a few days!
Correct answer: Thyroid acropachy. In this disease, there’s subperiostal bone formation, clubbing and swelling of toes and fingers. The fingers are often painful. Other complications (e.g. ophtalmopathy and dermopathy) are possible, as well.
