ABSTRACT

ABSTRACT Here we describe a rare case of a benign tumor in the lacrimal gland of a healthy 4-year-old girl. Mild proptosis was the only abnormality observed on clinical examination. Magnetic resonance imaging of the right orbit revealed an oval, solid, well-circumscribed, homogeneous mass extending from the lacrimal gland and measuring 2.5 × 2.3 × 1.7 cm without any evidence of invasion into adjacent bones. The lesion was surgically excised and histological analyses defined the diagnosis of oncocytoma of the lacrimal gland. Although rare, oncocytoma should be included in the differential diagnosis of lacrimal gland tumors.


Resumo Nós descrevemos um raro caso de tumor benigno na glândula lacrimal em uma criança sadia de 4 anos de idade. Clinicamente, a paciente apresentava apenas uma discreta proptose. A ressonância nuclear magnética (RNM) de órbita direita revelou a presença de uma massa oval, sólida, bem-circunscrita, homogênea, se extendendo a partir da glândula lacrimal, medindo 2,5 cm x 2,3 cm x 1,7 cm, sem nenhum sinal evidente de invasão a estrutura óssea adjacente. A lesão foi cirurgicamente removida e analizada histopatologicamente, sendo estabelecido o diagnóstico de oncocitoma de glândula lacrimal. Apesar de raro, o oncocitoma deve ser incluído no diagnóstico diferencial de qualquer tumor originado da glândula lacrimal.

ABSTRACT

ABSTRACT We describe an unusual case of acquired anterior staphyloma in a patient addicted to crack cocaine. At the beginning of his crack cocaine abuse, he noticed redness and irritation of his eyes. Over the next 4 months, the patient also noticed the onset of decreasing visual acuity in his right eye (OD). Initially, his visual acuity was light perception in OD, and slit-lamp examination revealed a corneal infiltrate with a peripheral perforation and an iris prolapse. The patient was hospitalized to ensure compliance with the prescribed treatment and was advised to undergo therapeutic keratoplasty; however, the patient left the hospital against medical advice and was lost to follow-up for the next 6 months. He returned with complaints of photophobia and the inability to close his right eyelids. At this time, his cornea had developed an anterior staphyloma and required a sclerokeratoplasty. Following surgery, the patient was again lost to follow-up.


RESUMO Descrevemos um raro caso de estafiloma anterior adquirido em um paciente viciado em crack. No início do uso do crack, paciente observou hiperemia e irritação nos seus olhos. Durante os próximos 4 meses, evoluiu com piora progressiva da visão em seu olho direito (OD). Inicialmente, sua visão no OD era de percepção luminosa e ao exame de biomicroscopia observava-se um importante infiltrado corneano com uma perfuração periférica e hérnia de íris. O paciente foi hospitalizado para garantir seu correto tratamento e indicado ceratoplastia terapêutica; no entanto, o paciente abandou o hospital e ficou 6 meses sem acompanhamento. Após esse período, paciente retornou queixando-se de importante fotofobia e inabilidade em ocluir o OD. Neste momento, sua córnea havia desenvolvido um importante estafiloma anterior e necessitou de uma escleroceratoplastia no OD. Após a cirurgia, mais uma vez o paciente abandonou o tratamento e perdeu o seguimento pós-operatório.
