Isolated circinate balanitis successfully treated with topical tacrolimus.

Area of Science:

• Dermatology
• Rheumatology
• Urology

Background:

• Reactive arthritis classically presents with a triad of arthritis, conjunctivitis, and urethritis.
• Circinate balanitis is a recognized manifestation of reactive arthritis, typically occurring alongside other symptoms.
• Isolated presentations of circinate balanitis are less common, posing diagnostic challenges.

Observation:

• A case report of an adult male patient presenting with isolated circinate balanitis is detailed.
• Dermoscopic examination provided specific features aiding in the diagnosis of this isolated condition.
• The patient's response to treatment was monitored.

Findings:

• The study successfully identified and documented the unique dermoscopic characteristics of isolated circinate balanitis.
• Topical tacrolimus 0.1% ointment proved to be an effective treatment modality for the patient's condition.
• This case underscores that circinate balanitis can manifest independently of other reactive arthritis symptoms.

Implications:

• This case expands the understanding of circinate balanitis' clinical spectrum, emphasizing isolated presentations.
• Dermoscopy is presented as a valuable tool for diagnosing isolated circinate balanitis.
• Topical tacrolimus offers a targeted and effective therapeutic option for isolated circinate balanitis, potentially avoiding systemic treatments.
