Plexiform schwannoma: an unusual clitoral mass

Acquired clitoral enlargement is a rare condition resulting from a variety of etiologies, including tumors and excess androgens. Few cases of nonmalignant schwannoma, a benign tumor of the peripheral nerve sheath, have been reported in the literature as causes of clitoral enlargement in patients wit...

Description
Summary:Acquired clitoral enlargement is a rare condition resulting from a variety of etiologies, including tumors and excess androgens. Few cases of nonmalignant schwannoma, a benign tumor of the peripheral nerve sheath, have been reported in the literature as causes of clitoral enlargement in patients without known neurofibromatosis. These painless, slow-growing tumors rarely recur once excised. We present the initial investigation of a patient with a large clitoral schwannoma and subsequent treatment with partial vulvectomy. The workup, including advanced pelvic imaging for diagnosis and surgical planning, as well as removal of the clitoral tumor with preservation of functional tissue and restoration of normal vulvar anatomy despite a large excision, is demonstrated.
