An array of unusual clinical features in a woman with amlodipine-induced linear immunoglobulin A disease()
Linear immunoglobulin A disease (LAD) is a rare, autoimmune, vesicular-bullous disease that is either idiopathic or drug-induced, most commonly by vancomycin and in rare instances by amlodipine. In drug-induced LAD, certain uncommon and atypical clinical features can occur. In our patient, a 49-year...

Sumario: | Linear immunoglobulin A disease (LAD) is a rare, autoimmune, vesicular-bullous disease that is either idiopathic or drug-induced, most commonly by vancomycin and in rare instances by amlodipine. In drug-induced LAD, certain uncommon and atypical clinical features can occur. In our patient, a 49-year-old woman with amlodipine-induced LAD, atypical features such as koebnerization and palmo-plantar involvement occurred. She presented with tense, clear fluid-filled vesicles, bullae, and erosions all over her body, especially on the palms and soles, with some lesions showing a string-of-pearls appearance. The lesions were preceded by pruritus, and the patient had changed her anti-hypertensive medication from telmisartan to telmisartan-amlodipine for previous 10 days. Skin biopsy and direct immunofluorescence testing confirmed LAD. During the hospital stay, along with new crops of lesions, a few vesicles were present along the lines where she had scratched and the band of tight elastic sleeves of the sterile gown she wore, which is suggestive of koebnerization. Knowing the atypical manifestations of drug-induced LAD may aid clinicians in determining an early diagnosis, and LAD should be an important consideration in the differential diagnosis of vesiculobullous disease with palmar-plantar involvement. Amlodipine is a commonly used anti-hypertensive drug, so knowledge of its potential to cause this disease is important. Furthermore, knowing the potential for koebnerization, avoidance of trauma and the gentle handling of these patients can lead to early recovery from this self-limiting disease. |
