[Giant cell collagenoma of the bulbar conjunctiva]. / Colagenoma de células gigantes de conjuntiva bulbar.

PURPOSE/METHODS: To report a rare case of a tumor in a conjunctival location, a giant cell collagenoma. Tissue was stained with hematoxylin-eosin, periodic acid-Schiff, and Masson's trichromic stain and studied by immunohistochemistry. RESULTS/CONCLUSION: The clinical and histopathologic features of conjunctival giant cell collagenoma are similar to characteristics of the same tumor occurring in other parts of the body. This is the first report of this tumor in the eye.

Endoftalmitis endógena por Nocardia asteroides en un paciente con lupus eritematoso sistémico / Endogenous Nocardia asteroides endophthalmitis in a patient with systemic lupus erythematosus

We report a case of endogenous nocardial endophthalmitis in a 32-year-old man with systemic lupus erythematosus. The patient developed pulmonary and ocular disease while on systemic corticosteroid and cyclophosphamide treatment. The intraocular infection progressed to a scleral fistula, and was treated with pars plana vitrectomy, lensectomy, intravitreous and intravenous antibacterial therapy. The diagnosis of Nocardia asteroides was made by isolation and growth of colonies from samples of a vitreous specimen and bronchioloalveolar aspirates. The eye became phthisical, it was eviscerated, and histopathogical examination was carried out.

Se describe un caso de endoftalmitis endógena por nocardia en un varón de 32 años con diagnóstico de lupus eritematoso sistémico. El paciente desarrolló compromiso pulmonar y ocular luego de meses de tratamiento con corticoides y ciclofosfamida. La infección intraocular, de rápida evolución a fístula escleral, recibió tratamiento con vitrectomía, lensectomía y terapia antibacteriana intravítrea y endovenosa. Se aislaroncolonias de Nocardia asteroides a partir de material vítreo y aspirado bronquioloalveolar. El ojo afectado evolucionó a ptisis bulbi y fue posteriormente eviscerado, y se realizó el estudio histopatológico.

[Intraocular cilia with macular pucker: clinicopathologic correlation]. / Cilio intraocular con pucker macular: correlación clínico-patológica.

PURPOSE/METHODS: To report the pathological findings in a case of intravitreous cilia with macular pucker. We considered clinical factors to establish treatment. A pars plana vitrectomy and premacular membrane peeling were performed. Surgical samples were removed and studied with PAS, hematoxylin-eosin, Masson's Trichromic and immunohistochemistry. RESULTS/CONCLUSION: The histopathological examination disclosed the presence of cilia partially surrounded by a cuticle layer and internal limiting membrane with a celullarity increase. Surgical extraction is indicated in those cases in which the intraocular cilia are associated with any surgically treatable process or when it produces ocular inflammation or visual disturbance.

[Cohen syndrome. Contribution to its clinical delineation]. / La sindrome di Cohen. Contributo alla sua delineazione clinica.

The authors report a case with features of the Cohen syndrome: characteristic cranio-facial appearance with prominent nasal bridge, short philtrum, prominent upper central incisors, micrognathia, truncal obesity of mid-childhood onset, muscle hypotonia, mental deficiency, limb anomalies associated with other clinical expressivity present among the previous reported cases. The reported case is of particular interest: the distal limbs anomalies are peculiar with marked shortening of metacarpals and metatarsals. A review of the other cases is also reported and discussed in order to stress the most frequent manifestations of the syndrome and delineate the major clinical characteristics.

[Reye's syndrome. Clinical and etiopathogenetic aspects. Case contribution]. / La sindrome di Reye. Aspetti clinici ed eziopatogenetici. Contributo casistico.

In this study the authors report a case of Reye syndrome in a three year old patient. The most likely etiopathogenetic mechanisms are analysed and incidence, clinical features and diagnostic criteria are discussed. The possible association between the development of Reye's Syndrome and the use of salicylates, particularly aspirin, during the preceding viral infection (influenza or chicken pox) is emphasized. We underline the importance of early diagnosis that facilitates the successful management of Reye's Syndrome.

[Hemifacial microsomia. Description of a case with associated rare multiple visceral anomalies]. / Microsomia emifacciale. Descrizione di un caso con rare anomalie viscerali multiple associate.

A case of hemifacial microsomia is reported in association with rare cardiac, lung and laryngeal abnormalities. Our case presents both atrial and ventricular septal defects, hypoplasia of the right lung and of the larynx. This variety of malformations is rarely present in other reported cases. The literature of hemifacial microsomia is reviewed and differential diagnosis is discussed.

El trasplante de cornea como via de trasmision de enfermedad. / Corneal transplantation as transmission way of diseases

Los autores revisan la literatura mundial con respecto a las enfermedades trasmitidas via trasplante de cornea y analizan los factores que influyen en dicha trasmisibilidad. Al mismo tiempo discuten las causas que provocan la exclusion de determinadas patologias de la lista de donantes, en un intento de unificar criterios entre cirujanos y banco de ojos
