    Primary localized amyloidosis presenting as diffuse amorphous calcified mass in both orbits: case report
    (2011) GONCALVES, Allan Christian Pieroni; MORITZ, Rodrigo Bernal da Costa; MONTEIRO, Mario Luiz Ribeiro
    Primary localized amyloidosis is rare in the orbit. We report the case of a 63-year-old woman that presented with bilateral proptosis and ophthalmoplegia. A computed tomography scan revealed an infiltrative amorphous and markedly calcified mass in both orbits while a magnetic resonance scan showed a heterogeneous hypointense signal on T2-weighted images. A biopsy was performed through an anterior orbitotomy. Microscopy revealed extracellular amorphous and eosinophilic hyaline material which stained pink with Congo red and displayed green birefringence on polarized microscopy, leading to a diagnosis of amyloidosis. The results of the systemic workup were completely normal. A two-year follow-up period without any treatment disclosed no worsening of the condition. While calcification of nonvascular orbital lesions has often been regarded as suggestive of malignant disease, our case is a reminder that it can also be a characteristic presenting sign of orbital amyloidosis.

    Acometimento orbitário na doença de Rosai-Dorfman
    (2011) OLIVEIRA, Cristiana Dumaresq de; GONCALVES, Allan C. Pieroni; MOURA, Frederico Castelo; ROSSATO, Luiz Angelo; MONTEIRO, Mario Luiz Ribeiro
    Rosai-Dorfman disease or sinus histiocytosis with massive lymphadenopathy is a rare idiopathic and benign clinical entity, characterized by histiocytic proliferation with linfofagocitosis. It usually presents with cervical lymphadenopathy although extranodal involvement may occur. The orbital region is one of the most common extranodal sites. It is usually a self-limiting disease with spontaneous resolution but surgical excision, corticosteroids and radiotherapy may be necessary. We describe the case of a 29-years-old male patient complaining of an orbital mass sensation for 6 months and a history of previous sinus involvement from Rosai-Dorfman disease. Ophthalmic examination showed proptosis of the right eye and swelling of right lower eyelid. Computed tomography of the orbits disclosed a solid extraconal lesion in the inferior right orbit. After surgical excision there was a significant clinical improvement. Histopathologic examination confirmed the diagnosis of Rosai-Dorfman disease. We also review the clinical picture and differential diagnosis of this condition.
