[Sclerokeratitis and invasive conjunctival squamous cell carcinoma].

Purpose/methods: To describe one case of invasive squamous cell carcinoma of the conjunctiva in a 74-year-old woman, who two years previously had presented with a lesion which appeared to be an anterior nodular scleritis.

Results/conclusions: An anterior nodular scleritis, which did not respond to therapy, preceded the development of a squamous cell carcinoma of the conjunctiva adjacent to it. In our patient, the conjunctival squamous cell carcinoma could have masqueraded as a scleritis, delaying the correct diagnosis and allowing orbital spread of the tumor.

[Treatment with topical interferon alone in severe conjunctivo-corneal neoplasia].

Case Report: A 78-year-old man was referred for evaluation of a limbic lesion in his left eye. This had a gelatinous appearance and an extension of 240 degrees . The lesion was clinically diagnosed to be a conjunctival and corneal intraepithelial neoplasia (CIN).

[Interferon alfa-2b treatment in selected cases of recurrent conjunctival intraepithelial neoplasia].

Purpose: To study the efficacy of topical and combined topical and subconjunctival interferon alfa 2b (IFN alfa 2b) in the treatment of recurrent conjunctival intraepithelial neoplasia (CIN) in those patients who present resistance or intolerance to topical mitomycin C (MMC) treatment or when it is not indicated.

Methods: Four patients (age range from 52 to 70) with histological confirmation of recurrent CIN were studied prospectively. Two patients were resistant to topical MMC, another one did not tolerate it, and in the last case, this treatment was not indicated due to a stem cell insufficiency associated to a trophic corneal ulcer.

[Severe retinal phlebitis in ocular bartonellosis].

Purpose/methods: To report the clinical case of a 34-year-old male with atypical ophthalmic manifestations of cat-scratch disease (ocular bartonellosis), including an extensive retinal phlebitis, as well as the evolution of the clinical picture with treatment.

Results/conclusions: The clinical diagnosis of ocular bartonellosis was serologically confirmed. Oral treatment with ciprofloxacine healed the phlebitis and the neuroretinitis, with a residual optic disk pallor.

[Neurotrophic keratopathy management with cyanoacrylate tarsorraphy and autologous serum].

Purpose/methods: Neurotrophic keratopathy is a degenerative corneal disease with a highly complex treatment caused by an impairment of corneal sensitivity. We report the case of a 47 year-old man with a refractory postherpetic neurotrophic keratopathy in his right eye and we discuss the treatment options.

Results/conclusion: The combination of cyanoacrylate with temporary tarsorraphy along with the administration of topical autologous serum eyedrops and systemic tetracycline, allowed to control the progression of the disease and to regenerate the corneal surface.

[Paralytic ectropion correction with porous polyethylene spacer by subciliar external approach].

Purpose: To evaluate the efficacy of porous polyethylene spacer in paralytic ectropion.

Methods: Nine eyes of 8 patients (5 male and 3 female, medium age 55.6 S.

[Bilateral lagophthalmos in lepromatous leprosy. Case report].

Case Report: A case of bilateral facial palsy with paralytic ectropion, lagophthalmos and corneal damage secondary to corneal exposure in a long-standing patient with lepromatous leprosy is presented. Correction of paralytic ectropion was performed by medial cantoplasty, tarsal strip and Medpor lower eyelid spacer implantation. Lagophthalmos was corrected by gold weight implant in the upper tarsus.

[Pseudomonas aeruginosa corneal abscess refractory to fluoroquinolones].

Purpose/method: To report a clinical case of a 21-year old male with a severe corneal abscess due to Pseudomonas aeruginosa refractory to intensive treatment with topical Ciprofloxacin.

Results/conclusions: A corneal scrapping performed after a wash-out period showed Pseudomonas aeruginosa specimens, which were not sensitive to any of the fluoroquinolones tested. A fortified topical treatment with Ceftazidime healed the corneal abscess.

[Mycotic dacryocystitis related to naso-lacrimal stent. Case report].

Case Report: A nasolacrimal stent was placed in a diabetic woman with a ten-year history of epiphora. Three months later the non-functional stent was removed and taken for histological study. A presumed diagnosis of fungical dacryocystitis was then established.

[Ophthalmological findings in nasopharingeal carcinoma].

PURPOSE/MATERIAL AND METHOD: To report a clinical case of a 64 year-old man with orbital involvement from a nasopharyngeal carcinoma. Relevant clinical and imaging (CT and MNR) data are reviewed. CLINICAL CASE/CONCLUSION: Nasopharyngeal carcinoma is an unusual tumor (0.

[Oncocytoma of the caruncle. Case report].

Case Report: A 63 year-old man with a six month history of a red-orange lesion located in the caruncle of his right eye is presented. Surgical excision was then performed, and the histological diagnosis of oncocytoma was established.

Discussion: The oncocytoma is an uncommon, relatively benign tumor, composed of transformed epithelial cells of the ducts.

[Vasoproliferative tumors of the ocular fundus].

Purpose: To establish the differential diagnosis from choroidal melanoma and other malignant tumors.

Methods: We report 5 patients with vasoproliferative tumors studied in our Hospital since 1993; diagnosis was mainly based on clinic appearance of the lesions. Each patient had undergone indirect ophthalmoscopy and ocular echography.

[Cellular neurothekeoma of the bulbar conjunctiva. A case report].

Case Report: Cellular neurothekeoma is a distinctive subtype of neurothekeoma with an undetermined histopathogenesis. We report a very rare case of bulbar conjunctiva cellular neurothekeoma in a 23-year-old woman.

Discussion: Neurothekeoma or nerve sheath myxoma is a rare benign tumor, which arises during childhood, and early adult life.
