Abstract

BACKGROUND: Bowen's disease, also known as squamous intraepidermal carcinoma, is a pre-malignant skin tumor with a potential to progress to an invasive carcinoma.
OBJECTIVE
The purpose of this study was to investigate the clinical and histopathological characteristics of Bowen's disease.
METHODS
A total of 45 patients with Bowen's disease were enrolled in this study. The hospital charts and histopathological slides from 1994 to 2005 were reviewed retrospectively at Seoul Veterans Hospital.
RESULTS
There were thirty-seven cases (82%) of single lesions and eight cases (18%) of multiple lesions. Thirty cases (81%) of solitary Bowen's disease were located in non sun-exposed areas. These included the trunk, extremities and genital area in decreasing order. Seven cases (19%) of solitary Bowen's disease occurred on sun- exposed areas including the face and the dorsum of the hand in decreasing order. Analysis of the clinical character of Bowen's disease was performed and results were as follows: the most common type was patch (20 cases; 44%), plaque (14 cases; 31%) and pigmented lesions (12 cases: 27%). Analysis of the histopathological character of Bowen's disease was performed and results were as follows: the most common type was irregular (18 cases; 46%), psoriasiform (11 cases; 28%) and verrucous, atrophic type in decreasing order. Of 18 cases where surgical removal was performed, there were 2 case (11%) of recurrence. Of 16 cases where cryotherapy treatment was administered, there were 3 cases of recurrence. And of 4 cases where CO2 laser therapy was used, there was 1 case (25%) of recurrence, in 2 cases where multiple or large-sized lesions were observed, clinical recovery processes were monitored after applying isotretinoin and 5-FU combined therapy, as well as surgical removal and cryotherapy combined therapy.
CONCLUSION
In Bowen's disease among Koreans, there were many distinctive clinical and histopathological features compared to those of non-Korean cases.
