Cerebellar liponeurocytoma (lipomatous medulloblastoma).

Liponeurocytoma (lipomatous medulloblastoma) is an uncommon clinicopathologic entity. We report a case of cerebellar liponeurocytoma in an adult and attempt to better characterize this uncommon lesion. A 43-year-old woman presented with symptoms and signs of increased intracranial pressure and cerebellar dysfunction. CT and MRI showed a heterogeneous well-circumscribed mass in the left cerebellar hemisphere with hydrocephalus. Complete surgical excision of the tumor was accomplished through a suboccipital craniotomy. Pathological examination with immunohistochemical study revealed a medulloblastoma with neuronal, astrocytic and lipomatous differentiation. Postoperative radiation therapy was given. After surgery, the patient was followed up for a 16 month-period; symptoms improved dramatically and no evidence of tumor recurrence was found. Careful analysis of the histopathological and immunohistochemical studies correctly identifies liponeurocytoma (lipomatous medulloblastoma). To our knowledge, only 16 cases have been reported. Although this lesion appears to have a better prognosis than the conventional form of adult medulloblastoma, complete surgical removal with postoperative radiation therapy is recommended.

[Orbital location of Kaposi's sarcoma].

Kaposi's sarcoma is a proliferative disease, probably induced by human herpes virus type 8 (HHV8). Its expression is cutaneous and visceral, with four clinical forms. An orbital location of Kaposi's sarcoma remains exceptional. In order to evaluate the epidemiological, clinical, and therapeutic objectives of this tumor location, we report a case of a 58-year-old patient hospitalized in the ophthalmology department for a surgically treated right orbital tumor.

[Histoid leprosy with erythema nodosum leprosum].

Histoid leprosy is a particular variant of lepromatous leprosy presenting as cutaneous or subcutaneous nodular and/or plaque-like lesions arising form apparently normal skin. It is characterized histologically by spindle-shaped histiocytes in interlacing bundles and whorls, containing numerous intact and rod-shaped Mycobacterium leprae. It can occur de novo or secondary in patients treated for a long course by dapsone alone. We describe a case of lepromatous leprosy treated according to the national Moroccan protocol who developed histoid lesions during his treatment by dapsone. The patient responded well to fluoroquinolone, rifampicin and clofazimine, with however, the occurrence of erythema nodosum leprosum.

[Multiocular renal cysts in adults. Two case reports].

The authors report two cases of renal multilocular cyst and review the cases reported in the literature, revealing the original features of this benign tumour which has an equal incidence in children and adults with a controversial acquired or malformative aetiopathogenesis, precise histological features, but a difficult preoperative and intraoperative diagnosis despite modern imaging techniques. In the great majority of cases, treatment consists in nephrectomy.

[Spontaneous perirenal hematomas. Report of 3 cases].

Spontaneous retroperitoneal hemorrhage is an uncommon affection, the diagnosis was recognized by sonography and CT scan, but the etiology remains unknown and exploration for diagnosis may become necessary. In the absence of an apparent etiology, patients with spontaneous renal bleeding should undergo radical nephrectomy, because of the extremely high incidence of small undetectable occult tumors. Three further cases were reported by the authors, who made a review of the literature.

[Aglomerular segmental hypoplasia of the kidney: report of a clinical case].

Aglomerular segmental hypoplasia of the kidney is a disease that is uncommon in the adult; the average age at appearance of symptoms is between ten and 15 years. A clear female predominance has been noted, and this disease is often misdiagnosed as chronic pyelonephritis. However, the radiological and pathological characteristics are different to the latter. The etiology of aglomerular segmental hypoplasia has not yet been determined. It is important to acquire further knowledge regarding this disease, as in certain cases this information could help to avoid unnecessary nephrectomy.

[Pyelocolic fistula: a case study].

In this study, the case has been reported of a left renocolic fistula that was detected in a patient with hepatitis C and cirrhotic complications who was hospitalized for urogenital tuberculosis. It was decided to perform left nephrectomy and digestive suture, but surgery was delayed due to hemostatic abnormalities and massive cytolysis, and the patient died before surgical treatment, three days after the discovery of the fistula. The findings in the literature have been reviewed, and the common occurrence of this type of fistula has been underlined. They are the most frequently encountered type with of entero-urinary fistula, and account for 60% of documented cases. Their etiological and clinical characteristics of have been described in detail. In general, treatment consists of performing a nephrectomy and digestive suture.

[Nodular fasciitis or pseudosarcoma].

Nodular fasciitis is a benign neoplastic and reactive proliferation of fibroblasts of soft tissues, which is often mistaken for a sarcoma because of its rapid growth, rich cellularity and mitotic activity. A case is reported that provides the opportunity to discuss the specific clinical and pathological features of nodular fasciitis.

[Myxoid liposarcoma of the spermatic cord].

A case of myxoid paratesticular liposarcoma in a 68-year old patient is reported. The evolution was normal during the follow-up period (22 months). Scrotal liposarcoma is a rare tumour: less than 100 cases were reported in literature. The diagnosis is difficult, clinical and radiological signs are the same as those of any intrascrotal tumour. Orchidectomy is the usual treatment, prognosis depends on the histological features, it is usually better than that of other paratesticular sarcomas. It did not need any additional treatment.

[Nosocomial infections in neonatal and pediatric intensive care. The appeal of ciprofloxacin].

UNLABELLED: Nosocomial infections, caused by multiresistant bacteria, are very common in neonatal intensive care units (NIU) and they engage the vital prognosis. MATERIAL AND METHODS: From January 1994 to December 1995, 29 children suffered from nosocomial infections due to multiresistant bacteria. RESULTS: Bacteria were isolated in blood cultures and/or in cerebrospinal fluid and included Klebsiella (14 cases), Enterobacter (eight cases), Pseudomonas (three cases), Acinetobacter (one case), Stenotrophomonas maltophilia (one case) and Flavobacterium odorantum (one case). After preliminary antibiotic therapy, ciprofloxacin was introduced and associated with another antibiotic for 10 days. Outcome was favorable in 25 cases with sterilization of blood culture. Four deaths were due to acute respiratory failure. One case of skin rash and five cases of transient thrombocytopenia were observed during the six days of ciprofloxacin therapy. No articular complication and no dental abnormalities were observed during the 14-38-month follow-up. Ciprofloxacin appears to be a good therapeutic choice for the treatment of severe nosocomial infections in NICU. Side effects are rare, mild, and transient. However, the prevention of nosocomial infection remains essential.

[Testicular metastasis of prostatic adenocarcinoma: report of 2 cases].

Prostatic carcinoma metastasizing to the testis is an extremely rare occurrence. In this study, two new cases have been reported of unilateral testicular metastases from an adenocarcinoma of the prostate. Unlike primary tumors of the testis, this type of tumor develops later in life (between 50 and 60 years of age), and is in most instances unilateral. It is generally discovered accidentally during orchiectomy or autopsy. It is not always easy to establish a morphological diagnosis, as the macroscopic appearance of the tumor may be normal. However, microscopic investigation reveals the presence of neoplasms of the testis.
