Abstract
BACKGROUND

This paper presents a case of malignant hidroacanthoma simplex (HAS) and review the literature of previous cases to summarize the histopathological and immunohistochemical features and display the dermoscopic features of malignant HAS.

CASE SUMMARY

We present an 88-year-old Asian female with malignant HAS. The diagnosis was made according to the histopathological and immunohistochemical results after biopsy. Previous case reports of malignant HAS were retrieved from PubMed to characterize the histopathological and immunohistochemical features. We also display the dermoscopic features of malignant HAS that have not been reported.

CONCLUSION

Our findings demonstrate that prompt surgical treatment is an effective strategy for malignant HAS. Histopathology and immunohistochemistry are valuable diagnostic tools. This is the first case report to display the dermoscopic features of malignant HAS, and we speculate that dermoscopy may contribute to the diagnosis of malignant HAS.

Keywords: Malignant hidroacanthoma simplex; Dermoscopy; Immunohistochemistry; Histopathology; Diagnosis; Case report

Core Tip: Malignant hidroacanthoma simplex (HAS) is a clinically uncommon malignant cutaneous tumour with only a few case reports. Herein, we present an additional case of malignant HAS. By combining this case with a literature review of previous cases retrieved in PubMed, we summarize the histopathological and immunohistochemical features of malignant HAS and found that timely surgical operation is an effective treatment. Furthermore, we first display dermoscopic features of malignant HAS and speculate that dermoscopy may be a valuable tool for the early diagnosis of malignant HAS.
