Immunohistochemical study of vascular endothelial growth factor (VEGF), tumor suppressor protein (p53) and intercellular adhesion molecule (ICAM-1) in the conjunctiva of diabetic patients.

The expression pattern of VEGF, p53 and ICAM-1 was studied in conjunctiva of diabetic patients with and without retinopathy. All patients underwent a complete ophthalmic examination, including retinal fluorescein angiography. Indirect immunoperoxidase method was performed on 20 eyes of 20 patients with type II diabetes without DR and on 5 eyes of 5 patients with PDR. A control study was performed on 6 normal conjunctiva undertaken during cataract surgery. Immunoreactivity of VEGF, p53 and ICAM-1 was found in epithelial, fibroblast and vascular endothelial cells. For the same duration of diabetes, a strong to moderate or weak immunoreactivity was observed in the conjunctiva of patients without retinopathy. In patients with PDR, the expression was strong for all these proteins. The immunoreactivity was correlated between VEGF, p53 and ICAM-1. In the normal conjunctiva, a weak to negative immunostaining was observed. The presence of these proteins in the conjunctiva of diabetic patients without retinopathy may add new data in the pathogenesis of diabetic retinopathy. Further studies are needed to confirm this hypothesis.

[Prostatic stromal sarcoma].

Prostatic sarcoma is a very rare tumour arising from the specialized stroma of the prostatic parenchyma. The clinical and histological features and biological behaviour of this entity are poorly elucidated at the present time. The authors report a case of prostatic stromal sarcoma in a 47-year-old man presenting with complete bladder retention. The initial diagnosis was that of benign prostatic hyperplasia and the patient was treated by suprapubic prostatectomy with no other complementary treatment. Histological examination demonstrated primary neuroectodermal tumour (PNET). The patient was subsequently lost to follow-up and was only reviewed 22 months later in a context of haematuria. Digital rectal examination revealed a large, soft prostate with an estimated weight of 83 grams on ultrasound. Transurethral resection was performed and histological examination of the resection material and review of the slides of the primary tumour showed identical microscopic and immunohistochemical features, corresponding to stromal sarcoma. The patient was treated by local and regional radiotherapy (60 Grays). With a follow-up of 36 months, he presents urinary symptoms with no signs of local extension or metastasis.

[Pelvic ganglioneuroma. Report of a case].

Ganglioneuroma is a rare benign tumor. It is the most mature of neurogenic tumors. We report a case of a pelvic ganglioneuroma diagnosed in 24-year-old pregnant woman who presented with an urinary infection. Echographic examination suggested an ovarian mass. At surgical operation, the tumor was close to the sacrum. A total resection of the tumor was performed. Pathological examination proved it as a ganglioneuroma. Sixteen months later, the patient is free from disease.

Scrotal calcinosis: pathogenesis and case report.

Scrotal calcinosis (SC) is a rare and benign condition defined as the existence of multiple calcified nodules within scrotal skin. We report the case of a 39-year-old male patient with a three-month history of scrotal tumours that increased rapidly in number and size. Histopathological and immunohistochemical investigations showed no evidence of epithelial structure. Whether SC is idiopathic or the result of the calcification of pre-existing cysts is still a controversial issue. In some cases, as well as in our case, no evidence of cystic structure was found around calcified material, despite minutely careful studies. This suggests that SC might be truly idiopathic.

[A particular hepatocellular carcinoma combining the ordinary and the fibrolamellar variant].

Fibrolamellar carcinoma (FLC) of the liver is a rare variant of hepatocellular carcinoma (HCC) occurring on non cirrhotic liver. Since its first description by Hugh Edmondson in 1956, 200 cases of FLC have been reported in the literature, but only some cases describe the association of the ordinary HCC with the FLC within the same lesion. We report in this study the case of a 14-year-old female patient with a hepatic mass whose radiological aspect evoked a nodular and focal hyperplasia. Histologically, this tumor was composed of area of FLC mixed with ordinary HCC. Staining for cytokeratine 7 was positive in the FL component and negative in the ordinary HCC component.

[Prognostic value of clinicopathologic factors in superficial bladder tumors: a retrospective analysis].

OBJECTIVE: To study, through a series of superficial bladder tumors, the prognostic factors of recurrence and tumoral progression. MATERIALS AND METHODS: This is a retrospective study of a series of 59 urothelial tumors of the bladder at stage pTa or pT1. The following parameters were considered: age, sex, treatment, stage and grade. The chi square test was used in search of a correlation between the different parameters and the course (recurrence and progress) of the disease. A multivariate analysis was undertaken by integrating factors correlated with the course. RESULTS: Thirty two tumors (54 %) had recured versus 27 (46%) without recurrence. Eight tumors (25 %) progressed in grade and 4 (12,5 %) had become infiltrative. Age beyond 65 years, tumoral size > 3 cm and multifocality were predictive factors of recurrence with a relative risks of 2,36, 3,28 and 3,88 respectively. In a multivariate analysis, these factors remained significant with adjusted relatif risks respectively of 1,36, 1,6 and 1,7.

[Pustular psoriasis in childhood in 15 cases].

Psoriasis is a common, chronic and recurrent, inflammatory disease of the skin. Children were affected in 30% of cases. Severe form can be observed: pustular psoriasis (PP), psoriatic arthropathy and erythrodermic psoriasis. There were 15 children with PP, with an age range of 1-15.5 years, (mean age 7.56 years). Psoriasis constituted 5% of the total dermatological disorders in children. The severe forms of psoriasis were rare in children Annular PP was the most common form of PP in children. Juvenile PP had generally better prognostic than in adults, but the evolution is characterized by recurrences.

[Epidemiological, clinical and parasitological data concerning intestinal amebiasis in northern Tunisia].

In order to evaluate the principal characteristics of the intestinal amoebiasis in the north of Tunisia, one retrospective study review all cases diagnosed in principal gastroenterologic sections of the hospitals of Tunis. Twenty height cases of intestinal amoebiasis, 10 of which have an inflammatory bowel disease associated were included. Watery stools containing blood and mucus were the most important symptoms (25 cases). The endoscopic exam showed for all the cases non specific lesions. The diagnosis was based on histologic exam in 21 cases, on the positivity of serologic tests in 3 cases and on the presence of E. histolytica/dispar cysts in stools in 6 cases. In two cases, the diagnosis was made by therapeutic test.

[Dermatofibrosarcoma in children. Report of 7 Tunisian cases].

Dermatofibrosarcoma (DFS) protuberans is a rare mesenchyma tumor in childhood characterised by slow growth. We report the result of a retrospective study of 7 childhood (4 males) cases of through a fifteen year period. The mean age was 13 years. 4 Tumors were (DFS) located on the limbs: 2 on the trunk: and on the scalp. Clinical types were multinodular and infiltrated in 3 cases, nodular in two cases and ulcerated with budding also in two cases. The mean delay between diagnostic and the appearance of the tumor was about 24 months for 4 initial tumors. Histological features were typical in all cases. We report 3 recurrences of dermatofibrosarcoma arising few months after surgical excision of an initial tumor, in one case the tumor was diagnosed histocytofibroma. Six patient underwent surgical excision with wide margins, and in one case the margins were considered borderline. No recurrences were reported, the follow-up was between 17 months to 9 years. It's a rare tumor in childhood, 160 cases were reported. The clinical and evolutive mode were entirely comparable to the adult cases. However the initial appearance as benign atrophic or indurated plaque is more frequent in childhood, but this appearance wasn't noted in our series.
