Improving the cytological diagnosis of intraocular lymphoma from vitreous fluid.

Aims: To improve the cytological diagnosis of retinal lymphoma on vitreous fluid using improved cell collection and systematic analyses.

Methods And Results: Since October 2010, we have developed and optimized in our department a method with which to perform the diagnosis of retinal lymphoma. The vitreous sample was collected in a tube containing RPMI-1640 medium, decomplemented fetal bovine serum, and gentamicin.

[Ocular conjunctival pathology. A ten-year retrospective study in Toulouse-Rangueil University Hospital and literature review].

Our study aim is to assess the distribution of conjunctival eye lesions received in our institution between 01/01/1999 and 16/10/2010, in order to put forward the diagnostic difficulties associated with this location and the specific terms employed for ophthalmologic pathology. Twenty-one samples were analyzed. The non-tumoral lesions accounted for more than one half (pterygium, pinguecula, epithelial cyst, foreign body).

Sphingosine-1 phosphate prevents ethanol-induced corneal epithelial apoptosis.

Background: Apoptosis is a programmed cell death in multicellular organisms, found in a wide variety of conditions, including inflammatory process, everywhere in the body, including the cornea and conjunctiva.

Aim: To evaluate the effect of a new topical formulation of sphingosine-1 phosphate on preventing apoptosis of the corneal epithelium.

Setting: Medical University.

Ceramide production associated with retinal apoptosis after retinal detachment.

Background: During retinal detachment, premature apoptosis of photoreceptors and a loss of optimally corrected visual acuity occur. We hypothesized that retinal cell death and generation of ceramide, a pro-apoptotic lipid, would progress as a function of time following experimental retinal detachment, and undertook to define the appropriate temporal window.

Methods: Unilateral retinal detachment was induced in white New Zealand rabbits by subretinal injection of sodium hyaluronate.

[Cytokeratins 7 and 20 immunohistochemistry in ampullary carcinomas].

Unlabelled: Ampullary carcinomas (AC) account for 33% of all surgically operable pancreatoduodenal tumors. The 5-year relative survival rate is 50% and tumoral stage is the main prognostic factor. However, among the three AC histological subtypes (intestinal, pancreatobiliary and mixed), a favorable prognostic has been reported for the intestinal subtype.

Silicone oil migration in the eyelid after vitrectomy for retinal detachment.

Purpose: To report a case of silicone oil intrusion in the upper eyelid, expressed by ptosis occurrence 19 years after surgery.

Methods: Vitrectomy followed by transscleral subretinal fluid drainage and silicone oil tamponade was performed on a 57-year-old man for retinal detachment. Nineteen years later, the patient was referred for mobile subcutaneous lumps of the upper right eyelid.

[Recurring bone epithelioid hemangioma].

Bone vascular tumors are very rare. Epithelioid types are described according to their architecture, their degree of vascular differentiation, and their cytonuclear atypia. The include epithelioid hemangioma, epithelioid hemangioendothelioma, and angiosarcoma.

[Retrorectal cystic hamartomas. Report of one case].

Retrorectal cystic hamartomas (RCH) are rare congenital lesions of the presacral space, of which 68 cases are reported under different terms. Clinicopathologic features are usually constant and similar to the present case. A 23-year-old woman complained of abdominal and perineal pains for several months.

PAS inclusions, immunoreactive tenascin and proliferative activity in low-grade chondrosarcomas.

To distinguish between chondrosarcoma (grade 1--borderline histology) and enchondroma, we examined six chondrosarcomas (grade 1--borderline histology) which looked like benign lesions. Their diagnosis, albeit based on clinical, radiologic and pathologic examinations, was not easily reached. Moreover, we examined six enchondromas and 11 chondrosarcomas, the diagnoses of which were straightforward.
