Primary schwannoma in a cervical lymph node.

Abstract

BACKGROUND:

Spindle cell neoplasms within lymph nodes are rare and include benign and malignant tumors and primary and metastatic tumors such as palisaded myofibroblastoma, leiomyoma, leiomyosarcoma, reticular cell neoplasms, and vascular sarcomas. Ancillary studies may help distinguish these neoplasms.

METHODS:

A 77-year-old white woman was seen with a painless, slowly growing mass of the left neck. Her clinical history was noncontributory. An excisional biopsy was performed without complication. There has been no recurrence, to date, of the lesion.

RESULTS:

Gross examination, microscopic examination, immunohistochemistry, and ultrastructural studies were consistent with the diagnosis of schwannoma arising within a lymph node.

CONCLUSIONS:

We report the first case of intranodal schwannoma arising in a cervical lymph node. The recognition of intranodal schwannoma is important because it is cured with excision, whereas some of the other diagnostic considerations for a spindle cell lesion within a lymph node may require radiation or chemotherapy.
