Small Vessel Vasculitis from Mycoplasma Infection and Concurrent Topical Nonsteroidal Anti-Inflammatory Drug (NSAID)...

Area of Science:

• Dermatology
• Rheumatology
• Infectious Diseases

Background:

• Vasculitis involves blood vessel inflammation, causing skin rashes and potential end-organ damage.
• Causes include autoimmune disorders, infections, and allergic reactions.
• Prompt recognition is crucial for effective management.

Purpose of the Study:

• To present a case of Mycoplasma-induced IgA vasculitis.
• To emphasize the importance of a broad differential diagnosis in vasculitis presentations.
• To highlight the need for early investigation and multidisciplinary care.

Main Methods:

• Case report of a 63-year-old woman presenting with petechiae, ecchymosis, and purpura.
• Initial diagnosis of hypersensitivity vasculitis after topical diclofenac use.
• Further investigation revealed Mycoplasma-induced IgA vasculitis.

Main Results:

• The patient required several months of multidisciplinary care for treatment and resolution.
• The case underscores the need for comprehensive workup in suspected vasculitis.
• Early identification of underlying causes (infection, autoimmune, hypersensitivity) is key.

Conclusions:

• Emergency physicians must consider a broad differential for rashes with petechiae and purpura.
• Investigating potential triggers like infections is essential.
• Timely, multidisciplinary management prevents complications and aids recovery.
