A 39-year-old carpenter came to the clinic complaining of swelling and pain in his thumb. He noticed the lump about six months ago, but it has slowly increased in size over time. He denies any trauma or injury to the thumb. The lump was painless initially, but he has recently started experiencing mild discomfort, especially when using his thumb for gripping activities. On examination, a solitary, slightly mobile, dome-shaped nodule approximately 1 cm in diameter is seen on the volar aspect of the left thumb, just proximal to the interphalangeal joint and was tender to palpation. The skin overlying the nodule was unremarkable, without any signs of inflammation, as shown in the image. The range of motion of the thumb is slightly limited due to pain. Based on the patient’s history and physical examination.

Making the proper diagnosis is one of the most important aspects of any medical student’s or junior doctor’s clinical training and hence we created Clinical Edge Cases.

Ace Qbank Clinical Edge helps our students put their knowledge of symptoms and physical findings to test by applying clinical reasoning and assessment concepts to a series of common clinical vignettes. Problem-based learning is being used to focus on the cause behind the presentation of a simulated clinical case.

Each simulated Clinical Edge case contains a list of common causes of the presented condition, offers abundant references to the presented case, making additional information easy to find
