Hysteroscopic Resection of Cervical Nerve Sheath Tumor, Goldfarb RS, et al. Figure 1. Sonographic view of cervical mass (arrow). PATHOLOGY Pathology of the endometrial polyp showed a hyperplas- tic polyp without atypia. The cervical mass showed a sharply circumscribed tumor of low cellular density par- tially covered on its surfaces by stretched-out endocervi- cal epithelium. The pattern had a neural appearance with intertwining bundles of stroma with widely spaced spindle cells with elongated nuclei, many with a wavy S- shaped pattern commonly seen in neural sheath tumors. The individual cells did not show any significant pleo- morphism and no mitotic activity. The overall appear- ance was that of a benign nerve sheath tumor. DISCUSSION Nerve sheath tumors of the uterine cervix appear to be a very rare entity. It is clinically difficult to distinguish them from myomas. Tumors that are part of a more gen- eralized condition may be neurofibromas.1,2 Other mass- es may exhibit characteristics that identify them as pri- mary malignant Schwannomas. These are more fre- quently found in the extremities, the head and neck region, the trunk, and the paravertebral areas.3 Certain light and electron microscopic findings,4 as well as the use of special stains, can confirm the suspected diagno- sis. Management of these masses will vary depending on the 146 JSLS (1999)3:145-147 Figure 2. Coronal (A) MRI view of cervical mass. Figure 3.

Hysteroscopic resection can be accomplished safely in the outpatient setting, eliminating the need for hysterectomy.
