Diagnosis and Management of Orbital Tumors

Nasopharyngeal carcinoma with orbital invasion

“…6 NPC with orbital invasion, however, is rarely reported in the literature, and is found in a relatively low percentage of patients with orbital tumour. [7][8][9][10][11] In this series, 13 cases were encountered, which represented 3.2 % of all orbital tumours (primary, invasive, and metastatic tumours) in patients in the study period. This percentage is high compared with the percentages in other published reports, which ranged from 0 to 3%.…”

“…This percentage is high compared with the percentages in other published reports, which ranged from 0 to 3%. [7][8][9][10][11] The higher percentage is probably due to the high prevalence rate of NPC in southern Chinese regions, with 15-30 per 100 000 males being diagnosed with the condition per year. 1 In Taiwan, NPC patients have usually presented with neck masses, nasal bleeding, and nasal congestion as the initial manifestations of the disease.…”

Bilateral microphthalmos and orbital cyst

“…The cysts project through a congenital defect (coloboma) in the wall of a microphthalmic eye and are lined by a neuroectoderm. 1,2 We present the clinical and histopathological findings of microphthalmos with orbital cyst in a 21-year-old woman who was followed for bilateral microphthalmos since birth and had recent onset of bilateral angle closure glaucoma.…”

Neurofibroma orbitário isolado e endotropia: relato de caso e revisão da literatura

“…Histopatologicamente são formados por diferentes combinações de células de Schwann, fibroblastos e axônios (1)(2) . Clinicamente, eles podem-se apresentar ou como massas bem circunscritas, isoladas ou múltiplas, ou como lesões mais infiltrativas de limites imprecisos.…”

“…Os neurofibromas não mostram predileção por faixa etária ou sexo (3) e podem aparecer em qualquer local, assim como no tecido ósseo (1) . Um outro tumor oriundo da mesma região e com características clínicas semelhantes é o neurilemoma, ou schwannoma (também chamado de neurinoma) (2) . O entendimento da anatomia dos nervos periféricos é essencial para a distinção desses dois tipos de tumores.…”
