Abstract
OBJECTIVE
To evaluate the rate of peristomal involvement in a large series of bullous pemphigoid (BP) patients and to focus on the clinical features and the course of the disease of these patients.
METHODS
Bullous pemphigoid patients were investigated retrospectively regarding the rate of peristomal involvement, and the data of these patients, including demographics, diagnosis leading to stoma placement, stoma type and stoma duration, treatment, and follow-up were evaluated in detail. In addition, the authors' results were compared with literature data.
RESULTS
The authors observed peristomal involvement in four cases (1.5%) (male/female: 1) among a cohort of 270 consecutive BP patients. The mean age at BP diagnosis was 69.5 ± 6.8 (63-78) years. Peristomal lesions occurred 4.7 ± 3.8 (1-10) years following stoma placement. Although three patients presented with BP lesions only on peristomal localization (colostomy limited), the fourth patient developed generalized pemphigoid lesions for 6 months followed by only peristomal involvement for 3 years. One patient was lost to follow-up. Topical corticosteroids (n = 3), systemic corticosteroids (n = 2), and dapsone (n = 2) were the treatment of choice in three patients, providing a complete response in a mean follow-up period of 4.7 ± 4 years without any mortality.
CONCLUSIONS
The high rate of peristomal BP patients in this series raised the possibility of misdiagnosis of this specific condition as irritant dermatosis. Peristomal lesions may be isolated as an initial presentation of BP or represent the recurrence. Recognition of peristomal BP showing a favorable prognosis compared with classical BP is important.
