[Chronic hematic cyst of the orbit (orbital subperiosteal hematoma)]. / Kyste hémorragique chronique de l'orbite (hématome sous-périosté orbitaire).

A case of chronic hematic cyst of the orbit which caused unilateral globe displacement with painful diplopia is described in a 72-year-old man. CT scans showed an extraconal soft tissue mass located between the orbital roof and the superior rectus muscle with a bone lysis. Characteristic appearance on MRI (benign signs, subperiosteal localization of the hematoma) has been confirmed by removal surgery. Chronic hematic cyst of the orbit is uncommon and MRI is helpful to establish this diagnostic.

[Definitive internal tamponade with silicone oil in certain cases of retinal detachment]. / Tamponnement interne définitif par huile de silicone dans certains cas de décollement de rétine.

PURPOSE: The aim of this study was to analyze the effect of definitively maintaining silicone oil in the treatment of certain cases of retinal detachment. MATERIAL AND METHODS: Sixteen cases of retinal detachment seen from July 1995 to April 1999 were retrospectively studied. For these eyes with residual visual acuity, we voluntarily maintained silicone oil. There were 11 men and 5 women, mean age 56 (range 24 - 82). Followup ranged from 18 to 45 months. RESULTS: We analyzed visual acuity outcome, complications, and main reasons for maintaining longterm silicone oil CONCLUSION: This study provided interesting insight concerning certain clinical situations where silicone oil has to be maintained definitively. In some cases, low, but useful, visual acuity can be achieved for long periods of time. This therapeutic approach would be particularly helpful for mono-ophthalmic patients.

[Successful multidisciplinary treatment for bladder cancer with priapism. A case report].

A 44-year-old man suspected of having transitional cell carcinoma (TCC) of the prostate was referred to our hospital. He had a painful semi-erect penis at his first visit. Then needle biopsy of the corpus cavernosum histologically revealed metastatic TCC. CT of the pelvis showed bilateral ureteral obstruction caused by the advanced tumor but no lymph node swelling was found. Under the diagnosis of prostatic TCC with penile metastasis, bilateral percutaneous nephrostomy followed by two courses of combination chemotherapy (IFEP regimen) was carried out, which resulted in the disappearance of priapism. Radical cystectomy with total penectomy was performed. The final pathological diagnosis was corrected to TCC of the urinary bladder with invasion to the prostate and metastasis of the corpus cavernosum and the right obturator lymph node. Enlargement of the prostate proved to be caused by glandular hyperplasia with atypical hyperplasia of the prostate gland. Three courses of adjvent IFEP chemotherapy was given post-operatively and he has been alive with no evidence of the disease for 10 months.
