Summary
A 71-year-old man developed contact dermatitis from a urological lubricant containing tetracaine after prostate surgery. Patch testing confirmed a severe allergy to the caine mix in the lubricant.
Area of Science:
- Dermatology
- Urology
- Allergology
Background:
- Transurethral resection for benign prostatic hyperplasia is a common urological procedure.
- Topical anesthetics are frequently used in urological procedures.
- Contact dermatitis is a common adverse reaction to topical agents.
Observation:
- A patient developed groin dermatitis 48 hours after transurethral resection.
- The surgical probe was lubricated with a urological ointment containing tetracaine.
- The patient had a history of perianal pruritus and fissures from antihemorrhoidal ointments.
Findings:
- Biopsy and patch testing revealed positive reactions to the urological lubricant and caine mix.
- The patient was diagnosed with systemic contact-type dermatitis due to the caine mix.
- Dermatitis resolved with topical steroids and oral antihistamines.
Implications:
- Urological lubricants containing topical anesthetics like tetracaine can cause systemic contact dermatitis.
- Healthcare providers should consider anesthetic allergies in patients with unexplained dermatitis post-procedure.
- Awareness of potential lubricant-induced allergies is crucial for patient safety in urological care.
