Background:
Langerhans cell histiocytosis affects mainly young children and features an accumulation of CD1a+ dendritic Langerhans cells in the bone, skin, and other organs. A few cases of Langerhans cell histiocytosis on the penis have been reported in the literature. We present a case of Langerhans cell histiocytosis on the penis and review the similar cases in the literature.
Case Presentation:
The patient was a 13-year-old boy who had a history of lymph node, femur bone, and pituitary-thalmic axis lesions from Langerhans cell histiocytosis who noticed a painful nodule on the prepuce of his penis. The histological and immunohistochemical examination fulfilled the criteria of Langerhans cell histiocytosis.
Conclusion:
We herein describe the case reported of Langerhans cell histiocytosis on the penis.
