ABSTRACT

RESUMO A miíase é a infestação dos tecidos humanos por larvas Diptera. O comprometimento ocular é raro. Os autores apresentam um caso de miíase na topografia do saco lacrimal e discutem as modalidades terapêuticas para o tratamento desta doença.

ABSTRACT

Here we describe the rare case of a 55-year-old man with medial rectus muscle myositis as an atypical presentation of non-Hodgkin B-cell mucosa-associated lymphoma (MALT). Pathology and immunohistochemistry of the affected muscle confirmed the diagnosis of a neoplasm. The primary etiology of orbital myositis is Graves' ophthalmopathy, but several other diseases may cause this clinical presentation. Therefore, the neoplastic causes must be eliminated from the differential diagnoses. non-Hodgkin B-cell mucosa-associated lymphoma is the most common histological type of lymphoma in the orbit, with the conjunctiva and lacrimal glands being the most commonly affected sites. However, it may also present in atypical forms involving others sites and tissues.


Descrevemos um raro caso de miosite do músculo reto medial como forma atípica de apresentação de linfoma não-Hodgkin de células B tipo MALT. A anatomia patológica e imuno-histoquímica do músculo afetado confirmaram o diagnóstico definitivo do caráter neoplásico da doença. As miosites orbitárias têm como principal etiologia a oftalmopatia de Graves, porém diversas outras causas podem apresentar-se dessa forma. Sendo assim, as causas neoplásicas devem ser descartadas. O linfoma não-Hodgkin de células B tipo MALT é o tipo histológico mais comum de linfoma orbitário, as regiões mais frequentemente acometidas são a conjuntiva e glândula lacrimal. No entanto, pode apresentar-se com formas clínicas atípicas, acometendo outras regiões e tecidos.
