Bronchogenic cysts of the neck: a rare localization and review of the literature.

Personal experience in the diagnosis and management of two patients, one adult and one child, with pathologically proven bronchogenic cysts is described. Both patients presented with a solitary neck mass that proved to be bronchogenic cysts on histological examination. Aim of the review is to define the cytology, histopathological and clinical characteristics of bronchogenic cysts and discuss the features that distinguish them from other cervical cysts. Definitive treatment requires surgical excision.

Follicular dendritic cell tumour of the cervical lymph node: case report and brief review of literature.

Follicular dendritic cell tumour/sarcoma is a rare tumour involving lymph-node or extra-lymph-node sites; review of the literature reveals very few cases of follicular dendritic cell tumour, probably since, in the past, the disease has often been mistaken for other neoplasms: low differentiated carcinomas and fusate cell carcinomas, sarcomas, melanomas, thymic neoplasms, Castle carcinoma and other dendritic cell tumours (especially interdigital cell tumour/sarcoma). In the case described here, attention is focused on the diagnostic difficulties and on the therapeutic profile, comparing data with those reported in the international literature.
