He had had the lesion for 10 years, and it had gradually increased in size. Physical examination revealed a single 35 × 23 mm lesion that appeared as a well-defined erythematous plaque on the dorsum of his left wrist, which had erosion and crust (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). The lesion was about the same size as the area covered by his wristwatch. A biopsy was performed and the histological examination revealed irregular acanthosis, full-thickness dysplasia of the epidermis, pleomorphism with hyperchromatic nuclei, and numerous mitoses. There was no invasion of atypical cells into the dermis. These histological features were consistent with those of squamous cell carcinoma in situ or Bowen’s disease (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>A‒B). As the patient did not want surgery, he was started on topical imiquimod 5% cream daily for 3 months, and the erythema and erosion of the lesion were reduced. 5-Fluorouracil cream was thereafter administered for 13 months, and the patient stopped using it of his own volition due to the complete improvement of the lesion.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0015" class="elsevierStylePara elsevierViewall">The patient had Bowen’s disease that may have been caused by chronic stimulation as a result of repetitive contact or friction with the case back of his metal wristwatch. The location of the lesion corresponded to the site as well as the size in contact with the metal on a daily basis. Although a metal patch test was not performed, we believe that the occurrence of Bowen’s disease was related not to a metal allergy, but to long-term chronic stimulation.</p><p id="par0020" class="elsevierStylePara elsevierViewall">Chronic stimulation leads to chronic wounds and scars, which can develop into squamous cell carcinoma.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> It has been reported that when a scar is formed, it interferes with the immune response, which leads to the formation of a tumor.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> This mechanism may be associated with the development of Bowen’s disease. Previously, a case of Bowen’s disease arising on an old scar site was reported, in which Bowen’s disease occurred at the site of a scar from an injury caused by a tin can as long as 50 years previously.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a></p><p id="par0025" class="elsevierStylePara elsevierViewall">It was reported that cutaneous scars subsequent to burns, radiation, trauma, and vaccination, are vulnerable sites for the development of neoplasms.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> Chronic stimulation or dental metal allergy have been reported as causes of oral SCC. In a report by Weber et al., among the 65 patients with oral SCC, 34% showed an allergic reaction to at least one metal that was immediately adjacent to the cancer site. The rate was 1.57 times higher than that of the controls.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a></p><p id="par0030" class="elsevierStylePara elsevierViewall">In the present case, we speculate that superficial damage may have been induced by chronic stimulation/friction with a metal wristwatch, leading to the development of Bowen’s disease during the repetitive repair process. The current case suggests that even chronic minor stimulation or friction without penetrating trauma or dermal injury may cause Bowen’s disease if repeated for a long time. Further studies are needed to clarify the causative mechanisms of Bowen’s disease.</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Financial support</span><p id="par0035" class="elsevierStylePara elsevierViewall">None declared.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Authors' contributions</span><p id="par0040" class="elsevierStylePara elsevierViewall">Maki Takada wrote the initial draft of the manuscript.
