An unusual case of Castleman's disease restricted to the neck

An unusual case of Castleman's disease (CD) restricted to the left cervical area is reported. CD is rarely confined to the cervical area; when it occurs, it is usually of the hyaline-vascular subtype and small in size. This case was atypical due to its histology (plasma-cell variant), big size (15 x 11 x 6 cm) and the absence of general symptoms. In spite of surgical excision, the disease recurred 11 months later. However, subsequent surgery followed by chemotherapy resulted in a long-lasting control of the disease.
