Myointimoma of the glans penis.
Myointimoma is a recently described benign tumor, which is regarded as a rare type of mesenchymal tumor of the penis. The present patient was a 50-year-old man who had a nodule located in the glans penis. He had a 2 month history of a mass. An excisional biopsy was performed. The histological findings revealed a multinodular tumor that was characterized by spindle-shaped cells located in the intravascular area. This case, in addition to 11 cases reported in the literature, demonstrates that the myointimoma is frequently misdiagnosed on clinical and pathological grounds because of its rarity. Histological and immunohistochemical features are summarized on the basis of the present case and previously published reports.
