Causes: Other Infections
Aside from syphilis, there are several other infections that can lead to dactylitis. One example is blistering distal dactylitis, which can occur due to bacterial skin infections. This condition is characterized by the presence of large, painful blisters filled with fluid on the fingers and toes. In addition, rare infections such as tuberculosis and leprosy have also been associated with dactylitis.
Diagnosing Dactylitis
Identifying dactylitis can typically be done by doctors through visual examination of a patient’s digits. However, in some cases, imaging tests such as MRIs, ultrasounds, and x-rays may be necessary to confirm the presence of this symptom. It is also crucial to determine the underlying cause of dactylitis as part of the diagnostic process. Additional blood tests or joint fluid tests may be required for this purpose. Failing to address the underlying condition can result in serious complications, and even with treatment, dactylitis may recur.
