Sporotrichosis associated with exposure to domestic cats is hyperendemic in Rio de Janeiro, Brazil. A review of the clinical records at our institute revealed four patients with clinical signs of dacryocystitis and a positive conjunctival culture for Sporothrix who were diagnosed with Sporothrix dacryocystitis. Three patients were children (< 13 years of age) and one patient was an adult. Two patients reported contact with a cat that had sporotrichosis. Dacryocystitis was associated with nodular, ulcerated lesions on the face of one patient and with granulomatous conjunctivitis in two patients; however, this condition manifested as an isolated disease in another patient. All of the patients were cured of the fungal infections, but three patients had chronic dacryocystitis and one patient developed a cutaneous fistula. Sporotrichosis is usually a benign disease, but may cause severe complications when the eye and the adnexa are affected. Physicians, especially ophthalmologists in endemic areas, should be aware of the ophthalmological manifestations and complications of sporotrichosis.

OBJETIVO: Caracterizar os achados órbito-palpebrais na neurofibromatose tipo 1 e relatar a abordagem cirúrgica realizada. MÉTODOS: Foram estudados retrospectivamente os pacientes portadores de NF1 com envolvimento órbito-palpebral atendidos no Ambulatório de Cirurgia Plástica Ocular do Departamento de Oftalmologia da Universidade Federal Fluminense e 38ª Enfermaria da Santa Casa de Misericórdia do Rio de Janeiro. RESULTADOS: Dos 16 pacientes estudados, 12 apresentavam neurofibromas órbito-palpebrais, 3 apresentavam glioma do nervo óptico e 3 algum tipo de displasia óssea levando à exoftalmia ou enoftalmia. Dez pacientes foram submetidos a algum tipo de cirurgia plástica reconstrutora. CONCLUSÃO: Os achados clínicos encontrados estão de acordo com o descrito na literatura, tratando-se de doença com expressividade variável. Geralmente os pacientes necessitam ser submetidos a múltiplas cirurgias.

PURPOSE: To study the orbital and eyelid manifestations of Neurofibromatosis type 1 and to report the surgical approach. METHODS: Retrospective study of patients presenting with neurofibromatosis type 1 examined at the Oculoplastic Department of the "Universidade Federal Fluminense and the 38th ward of the Santa Casa de Misericórdia do Rio de Janeiro". RESULTS: Of the 16 patients, 12 had orbital and eyelid neurofibromas, 3 had optic glioma and 3 had osseous dysplasia. Ten patients underwent reconstructive oculoplastic surgery. CONCLUSION: Our results are in agreement with the international literature. Most patients required multiple procedures.

Os autores descrevem um caso raro de histiocitoma fibroso acometendo o saco lacrimal. A paciente apresentava quadro clínico que simulava dacriocistite crônica, com dacriocistografia sugestiva de obstrução alta das vias lacrimais. A completa remoção cirúrgica do tumor e posterior dacriocistorrinostomia foram fundamentais no diagnóstico e controle da doença.

The authors report an unusual case of fibrous histiocytoma of the lacrimal sac. The patient presented with clinical features of chronic dacryocystitis. Dacryocystogram disclosed a high level obstruction. Surgical management was fundamental to the diagnosis and control of the disease.
