[Castleman disease with lateral neck outset. Report of a clinical case].

This work presents the case of a young woman with Castleman's disease, manifest as an isolated, asymptomatic swelling in the supraclavear fossae. A fine needle biopsy was performed on the swelling and cytology on this material proved insignificant (blood cells), while CT and MRI did not show any significant vascular components nor did they provide any elements decisive for diagnosis, the neoformation being similar to a reactive lymph node. To determine the nature of the mass, the lesion was removed by cervicotomy. Histology then led to a definitive diagnosis of a hyaline vascular variant of Castleman's disease. The literature on the topic was then reviewed with an eye to otorhinolaryngological manifestations and the histological aspects and clinical-diagnostic approach are discussed in detail.
