Carcinosarcoma of the lung is a malignant tumor composed of a mixture of carcinoma and sarcoma elements. The carcinomatous component is most commonly squamous followed by adenocarcinoma. The sarcomatous component commonly comprises the bulk of the tumor and shows poorly differentiated spindle cell features. Foci of differentiated sarcomatous elements such as chondrosarcoma and osteosarcoma may ...

Introduction. Primary breast sarcomas (PBSs) are rare nonepithelial breast tumors compromised of mesenchymal mammary tissue. Although its rare nature has made the best mode of PBS treatment difficult to determine, it seems better to treat it more like a sarcoma creating clear negative margins verses breast carcinoma utilizing lumpectomy, partial mastectomy, and total mastectomy. Case. A 47-year...

A 56-year-old woman who received surgery for left breast cancer 10 years previously underwent 18F-fluorodeoxyglucose positron-emission tomography (FDG-PET) for postoperative follow-up. FDG-PET revealed high uptake of tracer in the esophagogastric junction. A slightly elevated, lobular lesion was found in the lower third of the esophagus on upper gastrointestinal endoscopy. An endoscopic biopsy ...

Cancer-induced bone diseases are often associated with increased bone resorption and pathological fractures. In recent years, osteoprotective agents such as bisphosphonates have been studied extensively and have been shown to inhibit cancer-related bone resorption in experimental and clinical studies. The third-generation bisphosphonate, ibandronate (BM 21.0955), is a potent compound for contro...

J. S. A;, a 74-year-old man, presented with a four-week history of dysphagia, anorexia, and loss of weight. He stated that until a month previously he had been quite well apart from occasional episodes over the past two years of 'indigestion' and belching, readily relieved by medicines. The belching after meals had recently increased and was later followed by vomiting immediately after eating. ...

Carcinosarcoma has been reported in various sites, such as the lung, uterus, breast, bladder, and salivary glands (1-6). Primary carcinosarcoma of the skin is very rare. To the best of our knowledge, almost 50 cases have been reported to date in English in the literature. The disease is defined by two different malignant components (7). In the reported cases, the epithelial component was basal ...

Carcinosarcomas are rare, malignant tumours normally arising from the uterus, ovaries and fallopian tubes and having both carcinomatous (epithelial cells) and sarcomatous (connective tissue) components. This case describes the first published case of a carcinosarcoma of the spleen presenting as microcytic anaemia. A 74 year old lady presented with a two stone weight loss and was found to have a...

Malignant mixed Mullerian tumors are composed of a mixture of sarcoma and carcinoma. The carcinomatous element is usually glandular, whereas the sarcomatous element may resemble normal endometrial stroma (homologous or so-called carcinosarcoma). Here, we present a homologous type of malignant mixed Mullerian tumor of the uterus that presented as a cervical mass. We describe a 55-year-old patien...

A carcinosarcoma of the lung, as well as the paratracheal lymph nodes from the same patient, were subjected to immunofluorescent labeling with antibodies to tissue-specific intermediate-filament subunits, including desmin, vimentin, and prekeratin. Within the tumor mass two distinct populations of malignant cells were found: prekeratin-positive cells, corresponding to the carcinomatous componen...

UNLABELLED Primary liver carcinosarcoma is a very rare disease. There have been only a few cases described to date, none of which has been imaged by bone scintigraphy. A 69-year-old man who developed right back pain and weight loss was admitted to our hospital. Tenderness of the right upper abdomen, hepatomegaly, and a giant mass were the main physical examination signs. Abdominal ultrasonograp...
