Nodular hidradenocarcinoma on the scalp of a young woman: Case report and review of literature

BACKGROUND. Nodular hidradenocarcinoma was first reported as clear-cell eccrine carcinoma by Keasby and Hadley in 1954 (Cancer 1954;7:934-52) and rare malignant tumor. Several synonyms and related terms for nodular hidradenocarcinoma have appeared in the literature. OBJECTIVE. They have potential for uncontrollable local recurrence, tend to metastasize, and often cause death. Most cases have been reported in the pathology literature with limited clinical information. METHODS. We report a 27-year-old woman with nodular hidradenocarcinoma on the scalp. RESULT. The management of rare cases is not well defined. In our case, she was only treated with a wide local excision, and no recurrence was observed 2 years after excision. CONCLUSION. Most authors have concluded that early wide surgical excision of the tumor is the treatment of choice. The efficiency of adjuvant therapy generally has not established.
