First case report of locally advanced malignant nodular hidradenoma of the scrotum.

Background: Malignant nodular hidradenoma (MNH) is a malignant tumor of the eccrine glands, and most commonly involves the head, trunk, and extremities. To the best of our knowledge, MNH of the scrotum has not yet been described in the English literature. Despite the use of surgery, chemotherapy, radiotherapy, and hormonal therapy, optimal treatment of MNH is unclear. Case Report: We describe the case of a 30-year-old African American man who was diagnosed with locally advanced MNH of the scrotum and treated with surgery. More than 2 years after surgery, the patient is without evidence of disease. Conclusions: This is the first case report of MNH of the scrotum. Surgery alone may be sufficient for the treatment of localized or locally advanced MNH.
