Schwannoma of the Breast: Report of a Case

2005

View full text Add to dashboard Cite

This report describes a rare case of a schwannoma that developed in the left breast of a 45-year-old woman without von Recklinghausen's disease. The patient complained of a mass growing slowly in her breast for more than 4 years. She did not have any pain and denied any discharge from her nipple. A physical examination revealed a 3.1 x 2.3-cm, elastic-soft, smooth, and mobile lump close to the nipple of the left breast. Mammography revealed a circumscribed, oval-shaped, and equal dense nodule without microcalcification. On ultrasonography the lesion was found to be a well-demarcated, hypoechoic mass including a large cystic area, which led to the suspicion of a phyllodes tumor. An excisional biopsy was performed. A microcopic examination revealed a structure with interlacing bundles of numerous elongated spindle-shaped cells with a typical palisading pattern. These findings were compatible with schwannoma. A review of the English literature yielded 21 proven cases of breast schwannoma. In this report, we describe another such case and review those documented in the literature.

We report a rare case of schwannoma of the breast that occurred in a 79-year-old woman who did not have von Recklinghausenʼs disease. The patient complained of a growing mass and pain in her left breast for more than 6 years. An elastic-hard, smooth, movable tumor measuring 2.5cm × 2.3cm was palpable in the lower inner quadrant of the left breast. Mammography showed a high-density oval lesion with a smooth outline in the lower inner area of the left breast. Ultrasonography of the breast revealed a hypo echogenic, heterogeneous well-defined mass, which led to suspicion of a fibroadenoma or phyllodes tumor. An excisional biopsy was performed, and microscopic examination revealed interlacing bundles of spindle-shaped cells and nuclear palisading. Immunohistochemical staining showed that the tumor cells were diffusely positive for S-100 protein. These findings were compatible with schwannoma. If a tumor has a clear boundary, the possibility of a schwannoma should be kept in mind when making the preoperative diagnosis.

Recibido el 24 de octubre de 2012; aceptado el 26 de noviembre de 2012 Disponible en Internet el 11 de marzo de 2013 PALABRAS CLAVE Schwannoma; Neurilemoma; MamaResumen Los schwannomas o neurilemomas son neoplasias benignas originadas en las células de Schwann de la vaina de los nervios periféricos. Se presentan habitualmente en la cabeza, el cuello, el tronco o en las superficies flexoras de las extremidades, siendo su localización en la mama extremadamente rara. Pueden surgir de forma esporádica, o en el contexto de una neurofibromatosis.Una exhaustiva revisión de la bibliografía ha demostrado un total de 28 casos de schwannomas mamarios documentados en la literatura. En este artículo, presentamos un nuevo caso de schwannoma en la mama de una mujer joven, describiendo los hallazgos mamográficos, ecográficos e histológicos característicos de esta entidad. ß 2012 SEGO.

KEYWORDS Schwannoma; Neurilemmoma; BreastBreast schwannoma: Apropos of a case Abstract Schwannomas or neurilemmomas are benign neoplasms arising in Schwann cells of the peripheral nerve sheath. The most common locations include the head, neck, trunk and flexor surface of the extremities, the breast being a highly unusual location. These tumors may arise sporadically or in the context of neurofibromatosis.An exhaustive review of the literature revealed 28 cases of intramammary schwannomas reported in the English-language literature. We report a new case of Schwannoma of the breast in a young woman and describe its mammographic, ultrasound and histological features.
