Introduction: Bowen's disease (BD) commonly occurs in sites of chronic sunlight exposure such as head, neck and extremities. It rarely distributes on the nipple and areola.
Case presentation: A 59-year-old female presented with crusted plaque on the right breast for over 1 month. Physical examination found an asymptomatic plaque (5 cm × 5 cm) with irregular shape on the right breast. Histopathological examination suggested irregularly acanthotic epidermis and atypical epidermal cells. Dermis showed inflammatory cell infiltration. Immunohistochemical staining showed negative staining for cytokeratin 7 and cytokeratin 20, and positive staining for Ki67 (60%). The mass was excised and no recurrence occurred in the follow-up. Additionally, we reviewed the literature about BD of the breast and summarized the clinical manifestations, histological features, and treatment options.
Conclusion: We reported a rare BD case involving nipple and areola. Wide local excision and complete nipple excision are effective for patients with BD of the nipple and areola.
