To compare epidemiological, histological, therapeutic characteristics and prognosis of patients with breast cancer diagnosed during pregnancy with those diagnosed in postpartum period at a national expert center, « Cancer Associé à La Grossesse » network.

Immunotherapy is on the roll. After revolutionary effects in melanoma, immunotherapy is invading other locations. If current treatments, chemotherapies or targeted therapies block one pathway, immunotherapy should be understood as the activation of a whole system. Indeed, oncogenesis process is defined as an escape of the immune system and the stimulation of this system can block the carcinogenic process. The aim of the present review is to describe the place of immunotherapy in the treatment of solid cancers.

Percutaneous lung thermo-ablation has steadily been developed over the past 15years. Main indications are early stage non-small cell lung carcinoma (NSCLC) for non-surgical patients and slow evolving localized metastatic disease, either spontaneous or following a general treatment. Radiofrequency, being the most evaluated technique, offers a local control rate of about 80-90% for tumors <3 cm in diameter. With excellent tolerance and very few complications, radiofrequency may be proposed for patients with a chronic disease. Other ablation techniques under investigation such as microwaves and cryotherapy could allow overcoming radiofrequency limits. Furthermore, stereotactic radiotherapy proposed for the same indications is efficient. Comparative studies are warranted to differentiate these techniques in terms of efficacy, tolerance and cost-effectiveness.

The diagnosis of invasion of the carotid axis preoperatively is extremely helpful and determines the therapeutic approach as well as the prognosis for patients with tumours of the upper aerodigestive tract. A review of literature to refine the radiological choice between the different existing techniques is provided. It appears that echography gives excellent results.

To evaluate prospectively chronic gastrointestinal toxicity in patients with cervical cancer treated with conventional irradiation or with intensity-modulated irradiation (IMRT).

Tubulopapillary carcinomas account for 10% of renal cell carcinomas. They are more frequent in men than in women (sex ratio:8/1). The average period is the sixth decade. There are two anatomopathological types:the 1 corresponding to a proliferation of basophilic cells and type 2 corresponding to a proliferation of eosinophilic cells. We report the case of a 17-year old female patient with no particular past medical history presenting to the emergency department with pain in the right lumbar fossa and in the right flank associated with hematuria evolving for two days before admission, with loss of body weight and deterioration of the general status. Clinical examination on admission showed poor general condition. The patient was apyretic with blood pressure of 110 mmhg/70mmhg and a heart rate at 110 beats per minute. Abdominal examination based on patient's inspection showed curvature of the right flank with tenderness, and guarding on palpation. Hemoglobin levels in the blood were 6 g/dl requiring transfusion. Abdominal scan showed voluminous right renal inferior polar tissue formation measuring 10 cm/7.8 cm with peri-renal effusion of 17 mm thickness. Two days after admission patient's evolution was marked by deglobulisation associated with accentuation of the abdominal pains. The patient underwent hemostatic nephrectomy. Total enlarged right nephrectomy was performed via subcostal incisions. Histological examination revealed type 2 tubulopapillary carcinoma. Chest CT scan did not show secondary tumors.

Mammary-type myofibroblastoma (MTMF) is a rare benign mesenchymal tumor, initially detected in the breast. Its diagnosis is based on a spectrum of clinical, radiological and possibly histological parameters. We here report the rare case of a 50 year old male patient with mammary-type myofibroblastoma located in the axillary region. The peculiarity of our case lies in the presence of numerous mitoses and this was rarely described in the literature. The aim of our case study was to raise the problem of differential diagnosis of this rare tumor.

Burkitt's lymphoma (LB) is a type of malignant non-Hodgkin's lymphoma originating from malignant B-cell transformation and proliferation. Positive confirmation is based on biopsy of the tumor mass or bone marrow aspiration revealing the presence of tumor cells. We here report the case of a young man, about twenty years old, addressed for post tooth extraction gingival swellings evolving for 1 month. Anatomopathologic examination after biopsy complemented by immunohistochemistry confirmed the diagnosis of Burkitt's lymphoma. Treatment was based on chemotherapy. Although Burkitt's lymphoma is rare, it is an aggressive tumor that represents a real public health problem, hence the role of the dentists in early diagnosis, in order to allow rapid and appropriate management of the disease which is vital to the healing process.

Cardiac myxomas are the most common type of primary cardiac tumors. They mainly affect the interatrial septum and exceptionally the heart valves. Surgical excision remains the only therapeutic alternative. We here report the case of a 69-year old patient with no significant pathological history suffering from NYHA class II-III dyspnea associated with lipothymia. Transthoracic echocardiography showed a tight calcified aortic narrowing with aortic valve gradient of 58 mmHg. A sessile mass of 15mm diameter inserted into the posterolateral leaflet, without stenosis or mitral regurgitation evoking an atypical localization of myxomaor or fibroelastoma was detected at the level of the mitral valve. The examination was supplemented by ETO which confirmed the diagnosis of a mass involving the posterolateral leaflet. The patient underwent surgery via median sternotomy, under conventional extracorporeal circulation. Left atriotomy allowed to objectify a sessile mass of 15mm of diameter involving the auricular wall of the friable and easily cleavable posterolateral leaflet. Cauterization of the implant base via electric scalpel was then performed without any additional gesture on the posterolateral leaflet. Anatomopathologic analysis of the surgical specimen confirmed the diagnosis of myxoma. The patient also underwent aortic valve replacement with mechanical prosthesis. The postoperative course was uneventful. The patient was discharged on postoperative day 8. Cardiac myxoma involving the mitral leaflet is very rare. Surgical procedure attempting to resect the widest possible surgical margins remains the only therapeutic option to avoid the risk of recurrence.

The most common primary sites for bone metastases in men are lung, prostate, kidney, thyroid or bladder. Colorectal origin is rare. Few studies have described this type of metastases; the axial skeleton or the pelvis are the most common metastasis locations. Craniofacial location is exceptional. We here report the case of a 38 years old man treated for metastatic rectal cancer metastasized to temporal bone. He initially had undergone surgical procedure for low anterior resection, tumor was classified as pT3N0M0; 24 months after the patient had left exophthalmos revealing a temporal tumoral process. Evolution and context favoured metastasis. In conclusion, this study reporting an exceptional case of craniofacial bone metastasis from multi-metastatic colorectal cancer will enrich the scarce data reported in the literature related to bone metastases from primary colorectal cancer.

The lungs receive the entire venous drainage of the body. This explains the high incidence of pleuropulmonary metastases originating from several cancers. The goal of this is to study the clinical manifestations of pleuro-pulmonary metastases originating from extra-thoracic cancers. We conducted a retrospective study of patients with pleuro-pulmonary metastasis whose data were collected in our department between January 2006 and december 2014. 76 patient medical records were studied. The average age was 50 years (aged 21-89 years) with a male predominance in 57.8% of cases. Clinical symptoms were mainly cough (32.8% of cases), dyspnea (23.7% of cases) and hemoptysis (11.2%). Primary cancers responsible for various pleuro-pulmonary metastases found in our case series were dominated by breast cancers in 27.6% of cases, gastro-intestinal cancers in 15.8% of cases, genital cancers in 9, 2% of cases, sarcomas in 7.8% of cases, renal cancers in 5.2% of cases, bladder cancers in 5.2% of cases, prostate cancers in 3.9% cases, ENT cancers in 3.9% of cases, thyroid cancers in 3.9% of cases, skin cancers in 2.6% of cases and cancers of unknown primary origin in 14.4% of cases respectively. Several radiologic features of pleuro-pulmonary metastases have been found in our case series; they can be isolated or combined. The most common radiologic aspect was multiple pulmonary nodules in 52.6% of cases, followed by pleurisies in 34.2% of cases, diffuse micronodules in 23.6% of cases and a solitary nodule in 3.94% of cases. Secondary pleuropulmonary cancers are frequent. They come in 3rd place after lymph nodes and liver metastases and are found in 30% of autopsies of patients with neoplasia.

Acquired amegakaryocytic thrombocytopenic purpura is a very rare condition characterized by severe thrombocytopenia linked to the reduction or disappearance of megakaryocytes in the bone marrow. It may be primary idiopathic or secondary to many pathological conditions including hematologic disorders. We report the case of a 24-year-old patient admitted for haemorrhagic syndrome caused by immunological thrombocytopenic purpura. The diagnosis was acquired amegakaryocytosis after the failure of corticotherapy and the performance of myelography. The patient was treated with ciclosporin with rapid progression to acute myeloblastic leukemia. The progression of acquired amegakaryocytosis to acute leukemia is reported but it is generally not so rapid and above all it is preceded by myelodysplastic syndrome or medullary aplasia. This study highlights the importance of a close follow-up of these pathologies with a benign-like appearance.

Lingual thyroid is secondary to the absence of migration of the thyroid diverticulum. The latter develops locally, that is, at the level of the foramen caecum. It may be the only thyroid tissue present, or it may be associated with a normal thyroid. The occurrence of a lingual thyroid carcinoma is rare accounting for about thirty cases described in the literature. This study reports a case of vesicular carcinoma in lingual thyroid.

Our study aims to report a new case of leiomyosarcoma of the urinary bladder, a rare tumor, and to propose a new therapeutic approach, given the non-consensual nature of its treatment. A 31-year old patient, with no particular previous history, presented with total haematuria with clot formation. The clinical and paraclinical assessment showed a voluminous solid tumor mass occupying the apex of urinary bladder and extending to the right lateral wall, with infiltrating appearance, without lymph node involvement or invasion of local or distal organs. Surgical management was based on total laparoscopic cystectomy and bladder replacement by enterocystoplasty. The postoperative course was uneventful. Radiological examinations at 3, 6, 12 and 24 months showed no recurrence. Thus, adaptive surgery should be proposed on a case-by-case basis, to improve the quality of life of patients suffering from this condition.

Thymic neuroendocrine tumors (TNET) are rare, with little-known prognosis. This study aims to report a case of TNET and to highlight the diagnostic and therapeutic difficulties in low-resource settings. A 60-year-old man presented with chest pain, greasy cough and recent weight loss. Chest CT scan showed anterior mediastinal tissue mass. Histologic evaluation of a 4 months-biopsy specimen obtained from anterior mediastinotomy showed a well differentiated TNET, labeled intensely positive for chromogranin and synaptophysin. The search for other neuroendocrine tumors and the extent of extension were negative. The tumor was immediately inextricable and radiation therapy was unavailable. The patient underwent two lines of first line chemotherapy. At 16 months follow-up, the patient was asymptomatic but showed tumor progression. The diagnosis of TNET may be delayed when immunohistochemistry is not routinely performed. Chemotherapy is associated with symptoms improvement in palliative care situation.

Esophageal cancer is associated with poor prognosis. Its severity is linked to delayed diagnosis which is most often made once a cancer has metastasized, in Africa. Costal metastases are rare. We report a case of a 38-year old Senegalese patient with squamous cell carcinoma of the lower esophagus with lytic metastases to the ribs. Mrs. TD, aged 38, was admitted with painful swelling in right hemithorax associated with weight loss. The patient also reported mechanical dysphagia evolving during 4 months which had not motivated consultation. Clinical examination showed a poor general condition, a hard, sensitive swelling measuring 3 cm along its longer axis, located on the anterolateral surface of the right hemithorax at the level of the 5thrib. Biological examinations showed normocytic normochromic anemia with hemoglobin level of 9.4 g/dl, non-specific biological inflammatory syndrome, and hypercalcemia (corrected calcium = 107 mg/l. Oesogastroduodenal endoscopy showed a ulcerative, budding, stenotic lesion 32 cm from the dental arches. Anatomopathological examination of the biopsies revealed moderately differentiated squamous cell carcinoma. In addition to oesophageal tumor, thoracoabdominal-pelvic computed tomography showed bone lysis involving the anterior arch of the 5th rib, carcinomatous pulmonary nodules and bilateral pleural effusion. Pleural fluid aspiration through an exploratory needle showed serohematic fluid and the cytological examination of this fluid objectified carcinomatous cells. The diagnosis of squamous cell carcinoma of the lower esophagus with rib, pleural and pulmonary metastases was retained and palliative treatment was initiated. The evolution was marked by the death of the patient 3 months after gastrostomy, within a context of respiratory distress. The originality of this observation is related to the atypical seat of metastases of this cancer of the esophagus as well as the risk factors of this tumor. Cancer of the esophagus in young adults is a major problem in Africa. The challenge is to determine its risk factors in order to prevent its occurrence.
