[Recurrence of pseudomyxoma peritonei with liver and splenic metastases: about a case and literature review].

Pseudomyxoma peritonei (PMP) is a clinicopathologic syndrome characterized by mucinous ascites and pools of mucin resulting in neoplastic mucinous epithelium in the peritoneal cavity. PMP is uncommon and it is characterized by clinical and unusual pathologic manifestations posing diagnostic and therapeutic problems. Involvement of abdominal viscera and lymph node metastases are rare and sporadic cases have been reported in the literature.

[Pneumoblastoma in adults: a new case report and literature review].

Pulmonary blastoma is a rare tumor which has been mainly reported in children. It accounts for 0.25-0.

[Uncommon mammary-type myofibroblastoma unlike any other: about a case].

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.

Synchronous adenomyomas of the ileum in an adult-an exceptional cause of intussusception.

In this article, we report a case of two synchronous ileal adenomyomas leading to intussusception. This rare occurrence has never been reported in the literature. Our case is noteworthy, because the lesion is rare and should be considered in the differential diagnosis of intussusception in adults.

Non-traumatic myositis ossificans circumscripta: A diagnosis trap.

Myositis ossificans circumscripta (MOC) is a benign condition of non-neoplastic heterotopic bone formation in the muscle or soft tissue. Trauma plays a role in the development of MOC, thus, non-traumatic MOC is very rare. Although MOC may occur anywhere in the body, the lesions are localized predominantly in the high-risk sites of injury, such as the thigh, buttock, and elbow.

Malignant renal epithelioid angiomyolipoma associated with abdominopelvic hydatid cysts: a case report.

Introduction: The World Health Organization defines epithelioid angiomyolipoma as a potentially malignant mesenchymal neoplasm characterized by proliferation of predominantly epithelioid cells and as closely related to the triphasic (classic) angiomyolipoma. It can be benign, potentially aggressive or malignant. The pathologist's role is crucial in making a positive diagnosis, providing appropriate patient management and assessing prognosis.

Acute intestinal obstruction revealing synchronous gastrointestinal stromal tumors in a small bowel diverticulum and mucinous adenocarcinoma of the colon: a case report.

Unlabelled: Gastrointestinalstromal tumors are rare neoplasms and represent 0,1% to 3% of all gastrointestinal cancers. They are the most frequent mesenchymal neoplasms of the gastrointestinal tract with a malignant potential and unpredictable behavior. The synchronous association with other primary gastrointestinal carcinoma has been rarely reported in the literature with increasing number in the last ten years.

Combined myoepithelial carcinoma and myoepithelioma in soft tissue: a case report and review of the literature.

Introduction: Soft tissue myoepithelial carcinoma and myoepithelioma are rare entities, part of myoepithelial tumors. They were incorporated into the World Health Organization classification of soft tissue tumors in 2002. Here we present an exceptional case of myoepithelial carcinoma and myoepithelioma association.

Juxtaglomerular cell tumor: a distinct mesenchymal tumor of kidney.

Juxtaglomerular cell tumor (JGCT) is an unusual mesenchymal entity of the kidney. It is a benign renin-secreting tumor causing hypertension and hypokalemia due to secondary hyperaldosteronism. It is curable if it is discovered early and surgically removed, but may cause a fatal outcome usually due to complications of associated hypertension.

Renal myelolipoma: a rare extra-adrenal tumor in a rare site: a case report and review of the literature.

Introduction: Myelolipomas are uncommon, benign tumors composed of mature adipose tissue and hematopoietic elements. They mostly occur in the adrenal glands, but extra-adrenal myelolipomas have also been reported in other locations such as the presacral region, retroperitoneum, pelvis and mediastinum. Here, we present a case of an extra-adrenal myelolipoma in a rare site: the renal parenchyma.

A gallbladder tumor revealing metastatic clear cell renal carcinoma: report of case and review of literature.

Unlabelled: Metastatic renal cell carcinoma in the gallbladder is extremely rare, with reported frequencies of less than 0.6% in large autopsy reviews. Only 40 cases were reported in the literature.

Primary endobronchial leiomyosarcoma of the lung: clinical, gross and microscopic findings of two cases.

Primary leiomyosarcoma of the lung is an unusual malignant tumor. Among this entity, the endobronchial form is very rare and the preoperative diagnosis is extremely difficult. We present two different presentations and outcomes of primary endobronchial leiomyosarcoma of the lung.

Primary solitary fibrous tumor of the retroperitoneum.

Solitary fibrous tumor is an uncommon neoplasm affecting adults and typically located in the pleura and can also occur in a large number of other extra thoracic sites. We present the case of a solitary fibrous tumor (SFT) of the retroperitoneum and describe their histopathological and immunohistochemical features. The identification of SFT in the retroperitoneum is of importance because its clinico-pathological behaviour is still unclear.

Calcified multilocular thymic cyst associated with thymoma: a case report.

Introduction: There are few case reports of thymoma with a thymic cyst. Such an association renders it difficult for any pathologist to differentiate from other neoplasms, such as a cystic thymoma.

Case Presentation: A 50-year-old Berber woman from Morocco was admitted with a chronic cough of more than 10 years duration.

Spontaneous rupture of a recurrent hepatic cystadenoma.

Biliary cystadenoma is a rare cystic tumor of the middle aged woman that usually arises in the liver or occasionally in the extrahepatic bile ducts. It has a strong potential for recurrence and for malignant transformation. The lack of specific clinical and biological features hinders diagnosis before surgery.

Primary retroperitoneal mucinous cystadenoma with borderline malignancy in a male patient: a case report.

Introduction: Primary retroperitoneal mucinous cystadenoma is a rare tumor prevailing specifically in female gender. Its histogenesis is still unclear and its diagnosis is mainly based on morphological characteristics.

Case Presentation: the subject is a 44 years old man presenting an abdominal pain on the right side, with a palpable mass which appeared four months ago.

Pulmonary epithelioid hemangioendothelioma: a case report.

Introduction: The pulmonary epithelioid hemangioendothelioma is a rare vascular intermediate malignancy tumour.

Case Presentation: A 45-year-old man, he shows an isolated chronic cough with a preserved general state of health. The thoracoabdominal Computed tomography showed three well limited opacities of the right lung, among them one shows some calcifications; which we entirely resected by enucleation after a pneumotomy.
