Abstract
BACKGROUND The activation of Fas/Fas ligand (FasL) and DR4-DR5/tumor necrosis factor-related-apoptosis-inducing ligand (TRAIL) pathways in cancer cells triggers apoptosis. The objective of this study was to investigate the prognostic value of soluble FasL (sFasL) and soluble (sTRAIL) in the serum of patients with bladder cancer. METHODS The sFasL and sTRAIL levels in the sera of patients with bladder cancer or healthy donors were determined using the enzyme-linked immunosorbent assay. Micro-culture tetrazolium viability assay and Western blot were used to analyze cell cytotoxicity and death receptors protein expression respectively. RESULTS Whether no difference in sTRAIL levels was seen between patients and controls, the level of sFasL was higher in patients than that in healthy donors. According to, sFasL level was the highest in the serum of patients with superficial stage or low- and medium-grade cancer. Moreover, sFasL in patients with superficial noninvasive bladder tumors or low- and medium-grade cancers was higher than that in patients with invasive carcinomas and high-grade cancers. Patients with high levels of sFasL survive longer than those with low levels, probably related to the cytotoxic potential of FasL preserved in its soluble form. CONCLUSION The data suggest that monitoring the level of sFasL and its cytotoxic activity could be a prognostic marker in the follow-up of patients with bladder cancer.

Abstract
Angiomyofibroblastoma (AMF) is a rare benign mesenchymal tumor with tendency to arise in the lower genital tract of middleaged women, predominately in the vulva. A few cases of AMF in males have been reported involving the scrotum, perineum or spermatic cord. We report a new case of AMF arising in the right inguinal region of a 27-year-old man. The tumor was well-circumscribed, myxoid and measured 30 mm in maximum dimension. On microscopic examination, the tumor was composed of spindle cells without atypia and with less than one mitosis figure per 10 high-power fields. Multinucleated cells and mast cells were observed. The stroma was myxoid and edematous with abundant capillary-sized blood vessels. Immunohistochemical staining showed a strong immunoreactivity for desmin and smooth muscle actin. The tumor cells were negative for estrogen receptors and focally positive for progesterone receptors with a low proliferative index of Ki67 (< 5%). This unusual neoplasm should be distinguished from aggressive angiomyxoma and other myxoid malignant tumors.

Abstract
Background The aim of this study was to investigate the clinical significance of three immune cell-related transcription factors, T-bet, GATA-3 and Bcl-6 in bladder cancer in Tunisian patients. Methods Expression of T-bet, GATA-3 and Bcl-6 genes was assessed using RT-qPCR in 65 bladder cancers from patients: 32 being diagnosed as low- and medium-grade, 31 as high-grade, 25 as muscle invasive stage and 39 as non-muscle invasive stage. Gene expression was statistically correlated according to the grade, the stage, tobacco consumption, the BCG response and disease severity. Results T-bet levels in patients with high-grade bladder cancer were significantly elevated compared to patients with low- or medium-grade bladder cancer (p = 0.005). In invasive carcinoma (T2–T4), the T-bet levels were significantly higher than in superficial non-invasive bladder tumors (Tis, Ta, and T1) (p = 0.02). However, T-bet is predictive of the response to BCG. Its expression is high in good responders to BCG (p = 0.02). In contrast, the expression of GATA-3 and Bcl-6 in non-invasive carcinoma (p = 0.008 and p = 0.0003) and in patients with low- and medium-grade cancers (p = 0.001 and p < 0.0001) is significantly higher than in invasive bladder tumors and in patients with high-grade bladder carcinoma, respectively. In addition, heavy smokers, whose tumors express low levels of GATA-3 and Bcl-6, are poor responders to BCG (p = 0.01 and p = 0.03). Finally, better patient survival correlated with GATA-3 (p = 0.04) and Bcl-6 (p = 0.04) but not T-bet expression. Conclusions Our results suggest that T-bet expression in bladder tumors could be a positive prognostic indicator of BCG therapy, even if high levels are found in high-grade and stage of the disease. However, GATA-3 and Bcl-6 expression could be considered as predictive factors for good patient survival.

Abstract
BACKGROUND The deficiency of mismatch repair system is one of the main pathways in colorectal cancer. This system consists mainly of four proteins: MLH1, MSH2, MSH6 and PMS2. Colorectal cancer develops in the majority of cases from precancerous lesions called adenomas. Only few studies have reported on the deficiencies of these proteins in adenomas. AIM In this study we used immunohistochemistry staining in colorectal adenomas to assay functional status of MLH1, MSH2, MSH6, and PMS2 proteins. METHODS 102 adenomas from 93 patients were collected in our institution during six years (2007-2012). The immunohistochemical technique was performed with 4 antibodies: MLH1, MSH2, MSH6 and PMS2. The loss of expression was retained if adenomatous cells were not stained with positive internal control. Staining was considered as abnormal if nucleus of adenomatous cells showed low nuclear staining and / or heterogeneous one, while positive internal control had normal staining. RESULTS Loss of expression of MSH2 and MSH6 in adenomatous cells was found in only 1 case which was a tubular adenoma 3mm high-grade dysplasia. Abnormal staining of the adenomatous cells was noted in 23 cases (22.5%) for MSH2 and in 8 cases (7.8%) for MSH6. No cases showed loss of expression of MLH1 and PMS2. Abnormal expression of MSH2 and MSH6 was not correlated with sex of patients, the location of the adenoma, its grade of dysplasia and its histological type. CONCLUSIONS Loss of Mismatch repair proteins expression is a rare event in adenomas. However, the abnormal expression levels are higher in our study compared to those reported in the literature. This could reflect a higher rate of microsatellite instability in our patients. Multicenter and larger studies with molecular biology techniques are needed.

Abstract
INTRODUCTION Osteoclast-type giant cell tumors of the salivary gland are extremely rare; only 23 cases have been reported. Two presentations were observed: isolated tumor or tumor associated with a carcinomatous contingent. CASE REPORT A 51-year-old female patient consulted for a painless left retro-angulo-mandibular swelling having appeared 2 years before. This was a 2 cm parotid mass without facial nerve palsy or cervical lymphadenopathy. The patient underwent a superficial parotidectomy to remove the nodule. The direct microscopic examination revealed an osteoclastic giant cell tumor without any carcinomatous contingent. At immunohistochemistry, mononuclear cells were diffusely and intensely stained by anti-pancytokeratin, while multinucleated cells were totally negative and CD68 positive. The patient was not given any complementary treatment. She was followed-up 23 months later and did not present any signs of recurrence or metastasis. DISCUSSION The histogenesis and nosology of osteoclastic giant cell are currently unknown. Although this entity was not integrated into the latest WHO classification, most authors consider it as a variant of carcinoma. Published data on the epithelial or histiocytic nature of multinucleated cells is not consensual. Our case presentation supports the hypothesis of a histiocytic differentiation of giant cells and epithelial mononuclear cells.

Abstract
Fibroepithelioma of Pinkus is a rare cutaneous tumour. Its classification is controversial and is considered as a variant of either basal cell carcinoma or trichoblastoma. Its presentation as a multiple tumour is rare. We are reporting such a case occurring in a 55-year-old man presenting with multiple seborrheic keratosis-like lesions corresponding histologically to Pinkus tumours. The clinical diagnosis of Pinkus tumour represents a challenge. Histological examination is extremely useful in aiding in the diagnosis of difficult cases.

Abstract
BACKGROUND Primary testicular non-Hodgkin lymphoma (NHL) is an uncommon extra nodal presentation, accounting for 1% of all NHL and 1 to 9% of testicular neoplasms. Median age at time of presentation is 60 years old. Anthracycline based chemotherapies are most frequently used. AIM To analyze baseline characteristics, treatment modalities and survival of six cases of primary testicular non-Hodgkin lymphoma. METHODS We screened 46 testicular neoplasm cases registered from January 1999 to January 2009 and found six primary testicular lymphoma patients. These six cases were analyzed for baseline clinical features, investigations, treatment and outcome variables. RESULTS Median age was 50 years old and median duration of symptoms was 4 months. All patients had testicular swelling. Four patients had abdominal lymphadenopathy. Most patients had diffuse large B-cell histology. All patients underwent high inguinal orchidectomy and five were treated with anthracycline based chemotherapy. Four patients completed therapy and one of them relapsed two years later. CONCLUSION Primary testicular NHL is an uncommon entity and with current combined modality treatment, the outcome may be as good as nodal NHL.

Prognostic value of Pheochromocytoma of the Adrenal Gland Scaled Score (Pass score) tests to separate benign from malignant neoplasms. LA TUNISIE MEDICALE 2013; 91:209-215.

Abstract
BACKGROUND Differentiating malignant from benign pheochromocytoma has been challenging when based on histologic features. This is due to the definition of malignant pheochromocytoma which are defined by the presence of metastases. A PASS score was developed and according to many authors, a PASS score> =4 identified potentially malignant tumors. AIM To assess the prognostic value of PASS score in differentiating benign pheochromocytomas from malignant ones. METHODS The records of 11 patients with tumors diagnosed as "pheochromocytoma" were identified from 1970 to 2010 in the files of the pathology, intern medicine and biochemistry departments of the Charles Nicolle hospital and Pasteur Institute. Receiver operating characteristics (ROC) curve analysis was performed to evaluate the diagnostic performance of PASS. The logistic model was developed using the 11 predictive variables. Its performance was evaluated by calculating the area under the ROC curve and comparing it with that of the PASS. RESULTS In benign tumors, The PASS score was <4 in 3 cases and >=4 in 6 cases. In malignant tumors, the PASS score was >=4 in both cases. According to the ROC curve analysis, a PASS equal or superior to 4 identifies malignant pheochromocytoma with a sensitivity of 50% and a specificity of 45%. CONCLUSION I think that PASS score, despite its low sensitivity, may help to reserve the more aggressive treatment and narrow follow up for potentially malignant tumors. Widespread of this called score with complete clinical data will help to validate these findings and to add other prognostic factors of value that could be a part of this scaled score such as immunohistochemical findings.

Abstract
Salivary duct carcinoma of the parotid gland is an uncommon tumor, highly aggressive. About 200 cases have been reported in the English literature. Pathomorphologically, these tumors showed great similarities to ductal carcinoma of the female breast, which is why they described this tumor as “salivary duct carcinoma.” The authors describe a new case of salivary duct carcinoma of the parotid gland. We present the case of a 50-year-old patient with progressive facial paralysis. The MRI examination of the head showed two ill-defined formations. A malignant tumor was strongly suspected, so that a total left parotidectomy with excision of the adjacent facial nerve and left lymph node dissection was performed. Microscopic examination concluded to a salivary duct carcinoma of the left parotid gland negative with Her2/neu antibody with lymph node metastasis. There were no recurrences or metastases within 3 years of follow-up. Salivary duct carcinoma of the parotid gland is a rare tumor with an aggressive behavior. This is due to its propensity to infiltrate distant organs. The diagnosis is based on microscopic examination. Treatment modalities are non-consensual, but some authors advocate the necessity of aggressive approach, especially in tumors negative with Heur2/neu antibody. This is due to the fact that the overexpression of this antigen was reported to be associated with a poor prognosis.

Abstract
Background Erosive lichen planus (LP) of the soles is a rare variant of LP, characterized by chronic, painful, and disabling plantar ulcerations. Herein, we report a case with complete healing following treatment with systemic steroids. Case report A 38-year-old woman was referred with painful and disabling erosive bilateral plantar LP, which she had experienced for 6 weeks. A 1 mg/kg/day, oral prednisone therapy led to rapid improvement and complete healing within 3 weeks, with a sustained result under a low dose maintenance therapy. Discussion Ulcerative plantar LP is significantly known to be unresponsive to several topical and systemic therapies. Surgical excision and grafting is the treatment of choice. Systemic steroids are reported to have inefficient or partial results; both on cutaneous healing and on maintenance of the result. Our patient achieved complete cicatrisation with a sustained result of 3 months under a low dose of prednisone (5 mg/day).

Abstract
We report a new case of postvaccination morphea profunda (MP) in a child and discuss its different clinical presentations, prognosis, and therapy and its relationship with "solitary morphea profunda." A 2-year-old healthy girl presented with an induration of the anterior aspect of the left thigh of 9 months duration. The lesion had appeared 3 months after a third dose of diphtheria-tetanus-pertussis vaccine. Cutaneous examination showed an induration of 7 × 7 cm with an "orange peel" texture after pinching the skin. Histologic examination confirmed the diagnosis of MP. Systemic steroids (1 mg/kg/day) led to the stabilization of the lesion. After 4 months of treatment, we began the concomitant use of oral methotrexate (10 mg/wk) for 2 months. Methotrexate was then continued alone for 10 months, leading to a significant regression of the induration with no relapse.

Abstract
Pigmented Bowen disease (PBD) is a rare tumor characterized by increased melanin pigment in the epidermis or papillary dermis in addition to the typical findings of Bowen disease. We report the case of a 60-year-old woman who presented with a 6-month history of a gradually enlarging solitary dark brown plaque in her right inguinal region. Histopathology showed hyperkeratosis with parakeratosis, acanthosis, disorganization of epidermal architecture, atypical keratinocytes, and increased melanin pigment of the papillary dermis. Considering the clinical and the histological evidence, a diagnosis of PBD was established. Complete resection confirmed the diagnosis. Pigmented Bowen disease is an unusual form of squamous carcinoma in situ. Other tumors in the differential diagnosis include pigmented basal cell carcinoma and superficial spreading melanoma.

Abstract
Introduction Nevus lipomatosus cutaneous superficialis (NLCS) is a rare benign hamartomatous skin tumor characterized by dermal deposition of mature adipose tissue. It’s classified in two types: the classical form with multiple soft, pedunculated, cerebriform papules and nodules that coalesce into plaques, and the solitary form that consists of a solitary papule or nodule. In this study, eight cases of NLCS are reported. Methods The study was a retrospective case series including all patients with histopathologically documented NLCS who attended the Dermatology Department of Charles Nicolle hospital between January 1997 and December 2010. The objective of our study was to determine the epidemioclinical characteristics, the histopathologic features, and the treatment of this hamartoma. Patients included three males and five females aged between 7 and 41 years. Results In four cases hamartoma was present since childhood, and in the other four cases it appeared in the third and fourth decades. Classical form was noted in seven cases and the solitary form in one case. Lesions involved limbs in four patients and trunk in four patients. Seven patients underwent surgical excision, and for one case no treatment was proposed. Conclusion The multiple or classical form is largely predominant in our study. Habitually, NLCS has an asymptomatic course. Treatment is usually not necessary unless for cosmetic reasons; surgical excision is curative and recurrence after is rare.

Abstract
Erythema elevatum diutinum (EED) is a rare condition with an unclear pathogenesis. Initially classified within neutrophilic dermatoses, it is now considered as a leukocytoclastic vasculitis accordingly to its histopathologic pattern. Several clinical presentations as well as many associated diseases are reported in the literature. We report a new case of EED in a 58-year-old man who presented with a three-month history of plaques and nodules on the extensor surfaces of hands, elbows, knees, ankles, forearms, and buttocks. Histology showed a leucocytoclastic vasculitis, suggestive of the diagnosis of EED. Screening for an associated pathology, namely a paraproteinemia or a solid cancer, was negative. Treatment with dapsone leads to amelioration within few weeks.

Abstract
Vulvo-perineal Crohn's disease is a rare condition either when it is isolated or associated with digestive manifestations. In the former condition named metastatic Crohn's disease, it may constitute a diagnostic challenge and may be confused especially with other infectious or inflammatory disorders. We report a case of vulvo-perineal Crohn's disease in a 46-year-old woman. A 46-year-old woman was diagnosed with a vulvo-perineal Crohn's disease without digestive involvement. There was a chronic edema of the vulva with linear ulcerations on the inguino-crural regions and the buttocks fold, of 3 years. Treatment with metronidazole (1 g/day for 6 months) led to almost complete healing of the ulcerations with a sustained result. Physicians must be aware of the diverse manifestations and confusing presentations of vulvo-perineal Crohn's disease.

Abstract
BACKGROUND Malignant proliferating trichilemmal cyst is a rare tumour usually located on the scalp of elderly women. About 40 cases of malignant proliferating trichilemmal tumour have been documented. CASE REPORT We report a case of a malignant proliferating trichilemmal cyst of the scalp in a 57-year-old woman. On the vertex she had a voluminous vegetated and multinodular tumour measuring 7 x 5 cm with spontaneous and abundant bleeding, and another lesion of the scalp corresponding to a trichilemmal cyst. Based on histopathological findings, the case was diagnosed as malignant proliferating trichilemmal cyst. CONCLUSION Diagnostic, clinicoprognostic and histological features of this tumour are discussed. Treatment is not yet standardized given its rarity.

Abstract
BACKGROUND Trichoblastoma is a rare and benign adnexial tumor with characteristic histological features. It occurs on any hair folliclebearing location, and usually presents as a solitary lesion most often less than 2 cm in size. Giant trichoblastoma has been rarely reported in the literature. AIM To report a new case of giant trichoblastoma, misleading for malignancy. CASE REPORT A 57-year-old woman presented with a 5 cm-solitary asymptomatic nodular lesion of the scalp, of 28 years. It had been previously excised with recurrence and progressive regrowth. On examination, it was a dome-shaped, erythematous, firm, papillomatous, non infiltrated nodule. Full body work up revealed no metastases. Cutaneous biopsy concluded to trichoblastoma but failed to eliminate malignancy. After excision with secondary skin graft, histological examination confirmed the benignity with clear margins. There was no evidence of recurrence after a 5 year-follow-up period. CONCLUSION This case illustrates a rare clinical variant of trichoblastoma with an unusual important size. This can be misleading for malignancy, but the slowly progressive course of the tumour in our patient, together with histological benignity led to the correct diagnosis. This tumour is considered as a distinct entity by some authors.

Abstract
INTRODUCTION Ameloblastic fibro-odontoma (AFO) is a very rare mixed odontogenic tumor (2% of all odontogenic tumors). It is considered as a non-extensive non-aggressive tumor but recurrence and malignant transformation remain possible. We report a voluminous AFO in a child. CASE REPORT A 7-year-old boy presented with a right mandibular and facial swelling. The panoramic radiograph and CT scan revealed a voluminous unilocular radiolucent lesion (10 cm) with an impacted tooth that involved the ramus area and the angle of the right mandible. Enucleation and curettage was performed with a good outcome. There was no recurrence at ten months. DISCUSSION This case is exceptional because of the young patient's age, the large tumor diameter, and the good outcome after ten months. This tumor occurs more often in the posterior region of the mandible and is frequently seen in the first two decades of life. The diagnosis is made on radio-clinical data and may be confirmed by histology. A surgical treatment with complete tumor removal is recommended to prevent recurrence.
