The Malassezia yeasts are among the normal human cutaneous flora in adults. They are also reported as part of the microflora of male genital region, mostly in uncircumcised males. The prevalence of Malassezia yeast colonization on the glans penis of circumcised males is discussed in multiple studies. We report the case of a male patient with extensive pityriasis versicolor that does not involve the preputial space. 相似文献

The involvement of a retrovirus homologous to the mouse mammary tumor virus (MMTV) in the pathogenesis of human breast cancer (BC) has long been assumed, but has never been proven. Previous studies have reported the detection of MMTV-like env sequences in variable proportions that did not exceed 40% of BC cases in several countries. However, these viral sequences have been found in higher proportion (74%) in Tunisian diagnosed with BC during the seventies. This study is an attempt to evaluate the current prevalence of MMTV-like env gene in BC in Tunisian women. We used semi-nested PCR that amplify a 190-bp MMTV-like env sequence, followed by direct sequencing to screen a series of 122 cases of BC randomly selected. The findings were correlated to clinicopathological data and immunohistochemical expression status of progesterone and oestrogen receptors, HER2, and P53. Specific MMTV-like env sequences were found in 17 (13.9%) cases of breast carcinomas, whereas the same sequences were not detected in matched normal breast tissues. The presence of the viral sequences correlates inversely with progesterone receptor expression (6.8% versus 20.3%; P=0.03) and HER2 overexpression (3.1% versus 17.7%; P=0.04). This present study confirms the presence of MMTV-like env sequences in BC in Tunisian women but describes an important decrease in the prevalence of the viral sequences compared with previous studies. This reduction may be due to some changes in the virological characteristics or exposure to the virus. 相似文献

Cervix cancer remains among most commonly diagnosed cancer in developing countries. Except squamous cell carcinoma and adenocarcinoma, the etiopathology and oncogenic mechanisms of rare cancers remain largely unknown. The study was performed to investigate the value of HPV infection and the expression of p16INK4A and TP53 in rare primitive cancers of the cervix.We conducted a retrospective study of rare primitive cancers of the cervix. Main clinicopathological features were reported. HPV infection was detected by in situ hybridization. Expression of p16INK4A and TP53 was analyzed by immunohistochemistry.Overall, seven cases were identified, including basaloid squamous cell carcinoma (BSCC, n?=?2), small cell neuroendocrine carcinoma (SCNEC), granulocytic sarcoma without acute myeloid leukemia, leiomyosarcoma, primitive neuroectodermal tumor and botryoid-type embryonic rhabdomyosarcoma. The mean age of patients was 53.7 years. Four cancers were diagnosed at advanced stages. The prognosis was unfavorable and associated with patient death in five cases. HPV types 16/18 were detected in BSCCs and SCNEC. Strong and diffuse p16INK4A overexpression was described in the nucleus and the cytoplasm of all tumor cells of BSCCs and SCNEC. The remaining cancers exhibited only scattered and focal p16INK4A staining. Mutated TP53 protein was detected in BSCC (case 1) and GS.Rare cancers of the cervix are aggressive and associated with poor prognosis. In contrast to mesenchymal tumors, BSCCs and SCNEC are etiologically related to high-risk HPV infection and could be identified by block positive p16INK4A overexpression as common cancers of the cervix. TP53 mutations are not a negligible genetic event in rare cervical cancers. 相似文献

Thyroid nodules are frequent and sometimes they pose a diagnostic and prognostic problem. DNA ploidy study and cell cycle analysis could be of value in the distinction between benign tumors and malignant tumors. Formalin-fixed and paraffin-embedded tissues from 69 patients with different benign and neoplastic lesions were investigated. Nuclear DNA content in thyroid cells was measured after Feulgen staining using SAMBA 200 image analysis system. A diploid DNA stemline was revealed in 75% of histologically proven benign thyroid tumors (15/20) and aneuploidy was found in 57.2% of malignant tumors (28/49). There is a significant correlation between aneuploidy and extra-thyroid extension (p=0.007) and bilateral and/or mediastinal lymph node metastasis (p=0.02). In the majority of benign tumors (19/20), the proliferation index was lower than 3% (< or =3%) however, this index value was higher than 3% (>3%) in more than 83% of malignant tumors (41/49) (p<0.001). The S phase fraction analysis revealed that the threshold of 14% divide the near whole of benign and malignant tumors (p<0.001). Our findings show that in follicular lesions, proliferation index and S phase fraction study appears interesting and helpful in the distinction between benign and malignant tumors, and aneuploidy seems more interesting in prognosis evaluation of these tumors. 相似文献

Two new cases of human subconjunctival dirofilariasis are reported in Tunisia. Dirofilaria immitis was identified in the first case and Dirofilaria repens in the second. Diagnosis was made by histological examination of excised nodules. We note that the patients are young (8 and 10 years, respectively) and that cases of human dirofilariasis caused by Dirofilaria immitis are present in Tunisia. 相似文献

Résumé:
Les kératodermies palmo-plantaires (KPP) sont un groupe hétérogène de maladies cutanées, caractérisées par une hyperkératose des paumes et des plantes, parmi lesquelles on distingue trois groupes: KPP héréditaires, génodermatoses avec KPP et KPP acquises. Les KPP héréditaires sont classées selon le mode de transmission, laspect clinique et le type dhyperkératose (diffus, focal ou ponctué), latteinte dautres structures ectodermales, la présence ou labsence de symptômes associés non ectodermaux, les données histologiques et la physiopathologie. Nous présentons un bilan des connaissances actuelles sur les principales KPP héréditaires.* Les figures de cet article sont disponibles en couleur sur le site springerlink.com 相似文献

Dermatofibrosarcoma protuberans (DFSP) is a rare mesenchyma skin tumor. It is characterized by a slow growth with a high rate of recurrence but limited potential for metastasis. We report the result of a retrospective study of 18 cases of DFSP collected over 16 years in the dermatology department of La Rabta Hospital. The mean age was 32 years with a sex ratio of 1.57. The site of predilection was the trunk (77.5%). Histological features were typical in all cases with positivity for CD34 in 14 cases. Treatment was surgical in 13 cases. DFSP is a tumor of intermediate malignancy, which can have aggressive course. This tumor is best treated with surgery in which large excision are necessary to reduce the risk of recurrence. 相似文献

Basal cell carcinoma (BCC) is the most common malignant tumour of the skin frequently located on the head and chiefly on the nose. Cryosurgery is one of the methods to treat BCC. OBJECT: To determine the efficacy of cryosurgery of 17 BCC of the nose in terms of recurrence rates and cosmetic results. RESULTS: 15 patients were included with a median age of 73 years and a photo type III or IV in 86% of cases. Mean size of tumours was 12 mm. Lesions were chiefly located on the alae nasi (70.5%). Complications were few and minor. After an average follow-up of 13.5 months, recurrence rate was about 5.8% (one case). Cosmetic results were good or excellent in 14 cases/17; only one patient had developed a notch of the nose. CONCLUSION: Cryosurgery is a rapid, of a low cost technique and chiefly with good oncological and cosmetic results. 相似文献

Our retrospective study was performed on 10 cases of granulomatous mastitis registered in Obstetric Gynaecology Department and Pathology Department of CHU F. Hached, Sousse, during 8 years period. The mean age was 36.4 years (range 32-59). Among these 10 cases. 8 were observed in reproductive-age women and 2 were noted in menopausal women. Clinical findings showed unilateral breast nodule associated with inflammatory signs in 4 cases, mammelonary retraction in 2 cases and serous or sero-purulent mamelonnary flow in 4 cases. Mamnmographic examination suggested a malignant tumor in 5 patients. In all cases, the diagnosis is made by histopathology. Surgical treatment consisted in wide excision with drainage or radical mastectomy, eventually with combination with antibiotic therapy and non steroid anti-inflammatory drugs. Prognostic features showed a good cicatrization in 4 cases, local recurrence and cutaneous fistulization in one patient. Granulomatous mastitis aetiology is still unclear, auto-immune aetio-pathogenesis appears more interesting and should be clarified. 相似文献

The object of our study is to release the epidemiological, clinical and mycological characteristics of superficial fugal infections. A retrospective study was carried out during three years (1996-1998). Direct microscopy was positive in 86% cases, the culture in 62% cases. Trichophyton rubrum accounts for 85% of the dermatophytic flora. The superficial fugal infections account for 15% of the reasons for consultation in our service. They would touch according to data's of literature 2 to 13% of the general population. Trichophyton rubrum in accordance with the various series published, is the fungi most frequently insulated with variable rates between 46 and 82% of the superficial fungal infections. Any time, Candida albicans is prevalent on the level of the hands. 相似文献
