[Sebaceous carcinoma. Study of two cases]. / Carcinoma de glándulas sebáceas: presentación de dos casos clínicos.

CLINICAL CASES: A 94-year-old woman, who had had a chalazion for a period of 8 months, presented because of thickening of the eyelid with necrosis, madarosis and adenopathy. A 67-year-old woman, previously operated on for a sebaceous carcinoma, presented because of reddening of the conjunctiva and eyelid. Clinical evaluation revealed inflammation of the eyelid and an irregular and erythematous superior bulbar conjunctiva with disruption of the limbal architecture. DISCUSSION: A sebaceous carcinoma is a tumour which is difficult to diagnose and treat, because it can be patchy and has a tendency to pagetoid dissemination. Diagnosis requires a biopsy of the lesion and mapping of biopsies from the conjunctiva of the eyelid and eyebrow. The subsequent treatment depends on the extent of the tumour, and may involve simple cleavage, topical mitomycin C, radiotherapy or exenteration of the eyebrow.

[Endoscopic dacryocystorhinostomy: role of the ophthalmologist]. / Dacriocistorrinostomía endonasal: participación del oftalmólogo.

OBJECTIVE: To evaluate the results of endoscopic dacryocystorhinostomy (DCR) with or without support of the ophthalmologist. MATERIAL AND METHODS: A retrospective study of 100 cases of endoscopic DCR surgery conducted by an otolaryngologist between June 2008 and December 2009. Of the 100 cases, 50 were operated with surgical support of the ophthalmologist, who inserted Bowman probes in the upper and lower canaliculi, while in the other 50 cases it was the otolaryngologist who performed this, without support of the ophthalmologist. The evaluation of the results after 2 years included the subjective perception, the lacrimal patency after lacrimal syringing, and lacrimal functional test after modified Jones test. RESULTS: Of the 100 DCR reviewed, more than 50% required complementary treatment by the otolaryngologist, mainly septoplasty. As for the resolution of epiphora, without support of the ophthalmologist, 75% the patients reported an overall subjective improvement, but this reached 92% in the surgical group with support of the ophthalmologist, which was a statistically significant difference. CONCLUSIONS: Endoscopic DCR is effective in the treatment of epiphora, but its results improve when the ophthalmologist inserts the probes in the lacrimal canaliculi during the surgical procedure.

[Meningocele, glioma and optic nerve meningioma: differential diagnosis and treatment]. / Meningocele, glioma y meningioma del nervio óptico: diagnóstico diferencial y tratamiento.

PURPOSE: After studying 3 clinical cases, we have reviewed the clinical and radiological characteristics of meningocele, meningioma and optic nerve glioma. The differential diagnosis and therapeutic management are also discussed. METHODS: Review of three clinical reports of three patients seen in our unit and a bibliographic search concerning the diagnosis and therapeutic management of these three entities at the present time. RESULTS: Differential diagnosis has to be based on a wide range of parameters: epidemiologic (age, race, sex, prevalence of the tumors), clinical (visual acuity, perimetry, Hertel exophthalmometry and funduscopy) and radiologic (computed tomography and magnetic resonance). Anatomopathologic study is required only rarely. The therapeutic options are: observation, surgery and radiotherapy. CONCLUSION: A correct differential diagnosis is mandatory to be able to individualize the treatment for each entity (Arch Soc Esp Oftalmol 2009; 84: 563-568).
