[Skin metastasis from invasive bladder tumour]. / Métastase cutanée d'une tumeur vésicale infiltrante.

Metastatic spread of advanced transitional cell bladder carcinoma rarely involves the skin. However, the presence of a skin metastasis indicates at least microscopic dissemination of cancer cells to the liver or lung, corresponding to a poor prognosis. The authors report a new case of single skin metastasis during the course of a poorly differentiated stage pT3a N0 M0 transitional cell bladder carcinoma. The patient died 5 months after the appearance of the skin metastasis.

[Retrovesical hydatid cyst: diagnosis and treatment in 8 cases]. / Le kyste hydatique rétrovésical: aspects diagnostiques et thérapeutiques à propos de 8 cas.

INTRODUCTION: Hydatid cyst represents a real public health problem in Tunisia. Retrovesical hydatid cyst is rare (6% to 7%). It is considered to be an "aberrant" or "ectopic" site defined by the development of the parasite in the subvesical and retrovesical fat. MATERIALS AND METHODS: From 1988 to 2001, 8 patients with retrovesical hydatid cyst were hospitalised and operated in our Urology department at Sahloul Hospital in Sousse, Tunisia. The mean age of our patients was 41 years (range: 8 to 75 years). Signs of bladder irritation were the most frequent presenting complaint. Only one case was diagnosed on computed tomography performed for assessment of lumbar contusion. Total resection of the cyst and pericystic tissues was performed in 5 patients, with partial resection in the other cases. RESULTS: The postoperative course was uneventful and only one patient developed suppuration of the residual cavity, which responded favourably to antibiotics and ultrasound-guided drainage. CONCLUSION: The retrovesical site of hydatid cyst is rare and treatment is essentially surgical.

[Urachal cyst in the adult. A case report and review of the literature]. / Kyste de l'ouraque chez l'adulte. A propos d'un cas revue de la litterature.

Simple urachal cyst is a rare pathology in the adults. The diagnosis is rarely established clinically, it is based on ultra sonography and confirmed by anatomo-pathology. The authors report one case of urachal cyst in a 42-year-old patient who present bladder irritation symptom. The diagnosis has been established by ultra sonography. The mean complications of urachal cyst are infection and degenerescence. The treatment is usually surgical.
