ABSTRACT
OBSERVATION: A 29 year-old-woman presented with a massive painless slow-growing tumor of the right cheek, with a benign aspect on clinical examination. The CT scan with injection, showed a solid-cystic mass, well defined, and partially enhanced. The mass was easily removed with a complete endobuccal excision. The histological examination and immunohistochemical study revealed a paraganglioma. There was no postoperative complication. No recurrence was noted after six months of follow-up. DISCUSSION: The paraganglioma is a rare neuroendocrine tumor and its location in the cheek has never been reported.

Ocular amyloidosis a an uncommon condition and conjunctival involvement rarely occurs, representing 15% of all ocular localizations. Clinical manifestations show a polymorphism requiring a histological diagnosis. Based on two cases of primary isolated conjunctivo-palpebral amyloidosis, we discuss the different ocular sites. The first case involved false ptosis, a conjunctival infiltration and a lower eyelid tumefaction; all located in the left eye. The second case had ptosis, a right lower eyelid tumefaction with ectropion and esthetic damage. Amyloidosis was confirmed at histologic examination of the conjunctival mucous after a special congo red coloration. In order to affirm the isolated conjunctival localization, it is necessary to eliminate another amyloidis site. The treatment was surgical with excision and cure of ptosis. Ocular amyloidosis is a rare condition with polymorphism manifestations. Confirmation is histological. The greatest difficulty is management due to disease recurrence.
