Bowenoid papulosis. A clinicopathologic study with ultrastructural observations

Area of Science:

• Dermatology
• Oncology
• Virology

Background:

• Bowenoid papulosis (BP) is a recently described condition affecting young adults.
• Clinical presentation includes multiple papules, nodules, or plaques resembling warts or nevi.
• Microscopic examination reveals cytologic atypia, necessitating differentiation from squamous cell carcinoma in situ.

Purpose of the Study:

• To characterize the clinical and histological features of Bowenoid papulosis.
• To differentiate BP from other anogenital malignancies.
• To assess treatment responses and long-term outcomes of BP.

Main Methods:

• Retrospective analysis of 108 patients with anogenital lesions.
• Clinical and histological evaluation of lesions.
• Review of treatment modalities and patient follow-up data.

Main Results:

• Patients typically presented with multiple papules or plaques mimicking benign lesions.
• Histological atypia was noted, but differentiation from carcinoma in situ was usually possible.
• Conservative treatment was effective, though recurrences were observed.
• No cases of progression to invasive carcinoma were documented.

Conclusions:

• Bowenoid papulosis is a distinct entity manageable with conservative therapy.
• The condition is associated with human papillomavirus infection, with potential contributions from other factors.
• BP does not appear to evolve into invasive squamous cell carcinoma.
