[Show abstract][Hide abstract] ABSTRACT: Nervous central system metastases from head and neck squamous cell carcinoma (SCC) are rare. We report an exceptional case of isolated leptomeningeal and spinal cord involvement few years after the diagnosis of invasive SCC of the lip.
A 33-year-old man with a history of infracentimetric carcinoma of the lip developed back pain associated with progressive neurological disorders leading to paraplegia. This atypical presentation led to initial misdiagnosis, but radiological and cytological explorations finally confirmed the diagnosis of leptomeningeal and intramedullar secondary spinal cord lesions from his previously treated head and neck SCC. Systemic targeted therapy with epidermal growth factor receptor inhibitor and intrathecal chemotherapy led to prolonged disease stabilization.
To our knowledge, this is the first case of isolated neurological metastases from a head and neck SCC. Combination of systemic targeted therapy and intrathecal chemotherapy may be effective in such cases.
[Show abstract][Hide abstract] ABSTRACT: Synovial sarcoma (SVS) of the thyroid gland is exceedingly rare. We report the case of a 55-year-old man with a rapidly growing 7-cm neck mass. Because of suspicion of anaplastic thyroid carcinoma, a total thyroidectomy was planned, without preoperative cytology. During surgery, the tumor ruptured, leading to fragmented and incomplete resection. The morphological and immunohistochemical aspects suggested thyroid SVS, which was confirmed by fluorescent in situ hybridization (SYT gene rearrangement). The patient experienced immediate local relapse in close contact with large vessels and the thyroid cartilage and was referred to our institution. Doxorubicin-ifosfamide chemotherapy led to a minor response that authorized secondary conservative surgery. Because of microscopically incomplete resection, adjuvant radiotherapy was chosen and is ongoing 10 months after initial surgery. The prognosis of thyroid SVS is associated with a high risk for local and metastatic relapses. Pretreatment diagnosis is fundamental and may benefit from molecular analysis. Margin-free monobloc surgical excision is the best chance for cure, but adjuvant chemotherapy and radiotherapy deserve to be discussed.
[Show abstract][Hide abstract] ABSTRACT: Aggressive angiomyxoma (AA) is a rare benign soft tissue tumour usually affecting the pelvis and perineum of young women. Magnetic resonance imaging (MRI) is crucial in the management of AA patients for its diagnostic contribution and for the preoperative assessment of the actual tumour extension. Given the current development of less aggressive therapeutics associated with a higher risk of recurrence, close follow-up with MRI is fundamental after treatment. In this context, diffusion-weighted (DW) imaging has already shown high efficacy in the detection of early small relapses in prostate or rectal cancer.
We report here a case of pelvic AA in a 51-year-old woman examined with dynamic contrast enhancement and DW-MRI, including apparent diffusion coefficient mapping and calculation.
To our knowledge, this is the first description of DW-MRI in AA reported in the literature. Here, knowledge about imaging features of AA will be reviewed and expanded.
[Show abstract][Hide abstract] ABSTRACT: At first intention, US must be practice to explore a pelvic mass. If US diagnoses a complex mass, a pelvis MRI must be performed. MRI allows optimal characterization of normal and pathological soft tissues of the female pelvis through the use of standard morphological T1W and T2W sequences, fat-suppression techniques and perfusion- and diffusion-weighted sequences.
[Show abstract][Hide abstract] ABSTRACT: Two-stage hepatectomy uses compensatory liver regeneration after a first noncurative hepatectomy to enable a second curative resection in patients with bilobar colorectal liver metastasis (CLM).
To determine the predictive factors of failure of two-stage hepatectomy.
Between 2000 and 2010, 48 patients with irresectable CLM were eligible for two-stage hepatectomy. The planned strategy was a) cleaning of the left hepatic lobe (first hepatectomy), b) right portal vein embolisation and c) right hepatectomy (second hepatectomy). Six patients had occult CLM (n = 5) or extra-hepatic disease (n = 1), which was discovered during the first hepatectomy. Thus, 42 patients completed the first hepatectomy and underwent portal vein embolisation in order to receive the second hepatectomy. Eight patients did not undergo a second hepatectomy due to disease progression.
Upon univariate analysis, two factors were identified that precluded patients from having the second hepatectomy: the combined resection of a primary tumour during the first hepatectomy (p = 0.01) and administration of chemotherapy between the two hepatectomies (p = 0.03). An independent association with impairment to perform the two-stage strategy was demonstrated by multivariate analysis for only the combined resection of the primary colorectal cancer during the first hepatectomy (p = 0.04).
Due to the small number of patients and the absence of equivalent conclusions in other studies, we cannot recommend performance of an isolated colorectal resection prior to chemotherapy. However, resection of an asymptomatic primary tumour before chemotherapy should not be considered as an outdated procedure.

[Show abstract][Hide abstract] ABSTRACT: Solitary fibrous tumor (SFT), usually described in the pleura, is exceedingly rare in the prostate. We report a 60-year-old man with prostatic SFT revealed by obstructive urinary symptoms, and detected by ultrasonography. Computed tomography (CT) and magnetic resonance imaging suggested a prostatic origin. CT-guided tumor biopsy diagnosed a SFT. A cystoprostatectomy was performed. Pathologic examination showed a 15-cm tumor arising from the prostate and showing histological criteria suggestive of aggressiveness. The surgical resection margins were tumor-free. The patient was then regularly monitored and is still alive in complete remission, 28 months after surgery. In conclusion, we report a new exceptional case of prostatic SFT. We review the literature and discuss the challenging issues of misdiagnosis, prognosis and treatment.
[Show abstract][Hide abstract] ABSTRACT: Solitary fibrous tumors (SFTs) are mesenchymal neoplasms of fibroblastic origin, most commonly found in the pleura. Numerous extrathoracic locations have been reported during the last 2 decades. Herein, we report the first case of an SFT in the round ligament of the liver. A 46-year-old Caucasian man presented with a 12-month history of abdominal pain. An ultrasonography-guided microbiopsy first revealed a desmoid tumor. After failure of first- and second-line medical treatments (celecoxib and tamoxifen, then imatinib), histological reexamination was suspicious for a low-grade sarcoma. MRI was also suspicious for a malignant process. Hence, surgery was decided. Laparotomy found a huge and well-limited tumor that, unexpectedly, was appended to the round ligament of the liver and free from any other intra-abdominal contact. The tumor was easily removed. Excision was monobloc and macroscopically complete. Histological analysis diagnosed an SFT arising from the round ligament of the liver. No adjuvant treatment was given. Ten months after surgery, the patient is alive without any signs or symptoms of relapse. This is the first report of SFT arising from the round ligament of the liver. It illustrates the difficulty in diagnosing such tumors. Whilst diagnosis of SFT is rare, it should be kept in mind to allow early diagnosis and complete surgical resection, which provide the best chance for recovery.
[Show abstract][Hide abstract] ABSTRACT: We report here the case of progressive multifocal leukoencephalopathy (PML) related to human polyomavirus JC (JCV) infection after an allogeneic transplantation with umbilical cord blood cells in 59-year-old woman with follicular Non Hodgkin lymphoma. She presented with dysphagia and weakness; magnetic resonance imaging demonstrated marked signal abnormality in the sub-cortical white matter of the left frontal lobe and in the posterior limb of the right internal capsule. Polymerase chain reaction (PCR) analysis of the cerebrospinal fluid (CSF) was positive for John Cunningham (JC) virus. JC viral DNA in the CSF was positive, establishing the diagnosis of PML. Brain biopsy was not done. Extensive investigations for other viral infections seen in immuno-compromised patients were negative. The patient's neurologic deficits rapidly increased throughout her hospital stay, and she died one month after the diagnosis. These findings could have practical implications and demonstrate that in patients presenting neurological symptoms and radiological signs after UCBT, the JCV encephalitis must be early suspected.

[Show abstract][Hide abstract] ABSTRACT: This study retrospectively describes the outcome of a series of 38 patients (pts) with T4 anal carcinoma exclusively treated by radio and chemotherapy.
From 1992 to 2007, 38 pts with UST4-N0-2-M0 anal carcinoma were treated with exclusive radiotherapy and chemotherapy. All patients received external beam radiotherapy (EBRT) (median dose 45 Gy) with a concomitant chemotherapy (5-fluorouracil-cisplatin). Eleven patients received neo-adjuvant chemotherapy (5-fluorouracil-cisplatin). After 2-8 weeks, a 15-20 Gy boost was delivered either with EBRT (20 pts) or interstitial (192)Ir brachytherapy (18 pts). Mean follow-up was 66 months.
After chemoradiation therapy (CRT), 13 pts (34%) had a complete response, 23 pts (60%) a response >50% (2 pts were not evaluated). The 5-year-disease-free survival was 79.2 ± 6.5%, and the 5-year overall survival was 83.9 ± 6%. Eight patients developed tumor progression (mean delay 8.8 months), six of them requiring a salvage surgery with definitive colostomy for local relapse. Late severe complication requiring colostomy was observed in 2 pts. The 5-year-colostomy-free survival was 78 ± 6.9%. Patients who received primary chemotherapy had a statistically significant better 5-year colostomy-free survival (100% vs. 38 ± 16.4%, P = 0.0006).
T4 anal carcinoma can be treated with a curative intent using a sphincter-sparing approach of CRT, and neo-adjuvant chemotherapy should be considered prior to radiotherapy.

[Show abstract][Hide abstract] ABSTRACT: Primary leiomyosarcoma of the seminal vesicle is exceedingly rare.
We report a case of a 59-year-old man with tumour detected by rectal symptoms and ultrasonography. Computed tomography and magnetic resonance imaging suggested an origin in the right seminal vesicle. Transperineal biopsy of the tumour revealed leiomyosarcoma. A radical vesiculo-prostactectomy with bilateral pelvic lymphadenectomy was performed. Pathological examination showed a grade 2 leiomyosarcoma of the seminal vesicle. The patient received adjuvant radiotherapy. He developed distant metastases 29 months after diagnosis, and received chemotherapy. Metastatic disease was controlled by second-line gemcitabine-docetaxel combination. Fifty-one months after diagnosis of the primary tumour, and 22 months after the first metastases, the patient is alive with excellent performance status, and multiple asymptomatic stable lung and liver lesions.
We report the eighth case of primary leiomyosarcoma of the seminal vesicle and the first one with a so long follow-up.
[Show abstract][Hide abstract] ABSTRACT: Despite improvement in revascularization strategies, microvascular obstruction (MO) lesions remain associated with poor outcome after ST-segment elevation myocardial infarction (STEMI).
To establish a bedside-available score for predicting MO lesions in STEMI, with cardiac magnetic resonance imaging (CMR) as the reference standard, and to test its prognostic value for clinical outcome.
Patients with STEMI of<12 hours' evolution treated by percutaneous coronary intervention (PCI) were included. CMR was performed 4-8 days later, to measure myocardial infarction (MI) extent, left ventricular ejection fraction (LVEF) and volumes, and to identify MO lesions. An MO score was built from multivariable logistic regression results and included clinical, angiographic and electrocardiographic criteria. Adverse cardiovascular events were recorded prospectively after STEMI.
We analysed data from 112 patients. MO lesions were found in 63 (56%) patients and were associated with larger MI as assessed by higher peak creatine phosphokinase (3755 ± 351 vs 1467 ± 220 IU, p<0.001), lower LVEF (46.7 ± 1.5 vs 53.4 ± 1.6%, p<0.01) and larger MI extent (18.7 ± 1.2 vs 9.0 ± 1.3% LV, p<0.001) on CMR. MO score>4 accurately identified microcirculatory injuries (sensitivity 84%; specificity 82%) and independently predicted the presence of MO lesions on CMR. MO score>4 predicted adverse cardiovascular events during the first year after STEMI (relative risk 2.60 [1.10-6.60], p=0.03).
MO lesions are frequent in PCI-treated STEMI and are associated with larger MIs. MO score accurately predicted MO lesions and identified patients with poor outcome post-STEMI.

[Show abstract][Hide abstract] ABSTRACT: We report the case of an asymptomatic 56-year-old woman with a metastatic pancreatic endocrine tumor, fortuitously discovered by abdominal imaging. A CT-scan showed a large mass in the pancreatic tail invading the spleen and stomach; in addition, there was neoplastic thrombus within the spleno-mesentericoportal venous confluence and bilobar liver metastases. Surgical resection was performed in two stages. The first procedure was an extended left pancreatectomy with venous thrombectomy and "clearance" of the left hepatic lobe. During the interval, embolization of the right portal vein was carried out. Right hepatectomy and radiofrequency destruction of residual metastases was then performed. On the basis of completeness of the resection and the histopathological data, the patient did not undergo any adjuvant therapy, in accordance with French guidelines. At 1 year of follow-up, there was no evidence of recurrence.

[Show abstract][Hide abstract] ABSTRACT: Low-grade extraskeletal osteosarcomas (ESOS) are extremely rare.
We present the first case of low-grade ESOS of the chest wall, which occurred in a 30-year-old man. Because of initial misdiagnosis and patient's refusal of surgery, the diagnosis was done after a 4-year history of a slowly growing mass in soft tissues, leading to a huge (30-cm diameter) calcified mass locally extended over the left chest wall. Final diagnosis was helped by molecular analysis of MDM2 and CDK4 oncogenes. Unfortunately, at this time, no surgical treatment was possible due to loco-regional extension, and despite chemotherapy, the patient died one year after diagnosis, five years after the first symptoms.
We describe the clinical, radiological and bio-pathological features of this unique case, and review the literature concerning low-grade ESOS. Our case highlights the diagnostic difficulties for such very rare tumours and the interest of molecular analysis in ambiguous cases.
