Lymphoma of cheek: a case report.

Lymphoma of cheek is a rare ad uncommon disease, representing 2,5% of malignant lymphoma. The cause is unknown but there are a lot of risk factors such as Helicobacter pylori and Epstein Barr virus. Symptoms are aspecific and may be confused with otolaryngological benign diseases. We present a case of B cell lymphoma of the cheek, which presented with a history of a slowly growing swelling of 3 months duration, resistant to NSAIDs and antibiotic therapy. Biopsy of the mass led to diagnosis of lymphoma. Blood investigations, ultrasonography and CT scan helped to reach this result. This case report shows that an accurate clinical examination, a cytohistological and immune-histochemical diagnosis by fine-needle aspiration biopsy (FNAB) are fundamental to obtain a diagnosis and to decide therapy.

A large calcified retroperitoneal extraskeletal osteosarcoma with consequent bilateral hydronephrosis.

Extraskeletal osteosarcoma (ESOS) is a rare malignant mesenchymal neoplasm that accounts for less than 4% of all osteosarcomas and approximately 1-2% of all soft tissue sarcomas. The tumor is typically located in the deep soft tissues, without attachment to skeletal bones. Although ESOS has been found todevelop virtually in every organ, its most common locations are the limbs. In the case of abdominal or pelvic lesions the diagnosis can be very difficult, thus it necessarily requires confirmation after exploratory laparotomy and histopathology. Such tumors may reach enormous sizes before detection because the enlarging mass may not be associated with pain. ESOS may be one of the differential diagnoses to be considered in the case of calcified masses arising in retroperitoneal space. Here we describe a bulky, bilateral, metastatic ESOS arising from the retroperitoneum and causing obstructive uropathy with consequent hydronephrosis.

Intestinal lymphoma: a case report.

Primary intestinal lymphoma is rare representing about 0.5% of all colonic malignancies. It can be classified into two principal categories: follicular B cell lymphomas and intestinal T cell lymphomas. Other intestinal diseases are very important such as immunoproliferative small intestinal disease (IPSID), a prelymphomatous process, and MALT lymphomas, caused by infection of Helicobacter pylori (H. Pylori). We present a 79-year-old male patient which presented with abdominal pain in the upper parts of abdomen of four months' duration, colic timpanists, tenderness, distention, weight loss. Sometimes the abdominal pain decreased expelling diarrheal dejections. Histological and immune-histochemical tests on bioptic piece helped to reach the diagnosis of lymphoma but only after histological investigation on operative piece was made the diagnosis of B-cell lymphoma. This case report shows that an accurate diagnosis, the evaluation of the extension and the presence of particular infections and/or co morbidities (H. Pylori positive, age, performance status) are fundamental to decide the therapeutic protocol.

Ultrasonographic diagnosis of obstructive jaundice.

The diagnostic accuracy of ultrasonography in differentiating between medical and surgical jaundice (99%), and in revealing the site (80%) and nature of the obstruction (79.8%) was assessed in a study on 128 jaundiced patients. The validity of this diagnostic procedure is underlined and its use is recommended in patients with obstructive jaundice.
