Substernal Mass: A Rare Presentation of Hepatocellular Carcinoma.

A 62-year-old female with a history of hepatitis C presented with one week of worsening abdominal distension. On physical examination, she had icterus, abdominal distension, shifting dullness, and a positive fluid wave. Computed tomography (CT) of the abdomen and pelvis demonstrated a small left hepatic lobe lesion and moderate ascites.

Dietary Garcinol Arrests Pancreatic Cancer in p53 and K-ras Conditional Mutant Mouse Model.

Pancreatic cancer (PC) patients have poor prognosis and survival rate. Gemcitabine, the drug of choice has a dismal 15% response rate. Earlier, we reported that Garcinol alone and in combination with gemcitabine showed a dose-dependent favorable response on PC cell lines.

Fine-needle aspiration diagnosis of high grade adenoid cystic carcinoma metastatic to the pancreas.

Pancreatic tumors are mostly primary tumors, with only rare metastatic tumors described in the literature. Here we report an unusual case of fine-needle aspiration (FNA) diagnosis of high grade adenoid cystic carcinoma of the parotid gland metastatic to the pancreas. The aspirate smears were moderately cellular and revealed numerous basaloid neoplastic cells.

Subcutaneous polypoid lipoma of the first intermetatarsal space mimicking rudimentary polydactyly.

A case of a subcutaneous polypoid lipoma, presenting as a rudimentary polydactyly, is reported. The lesion was located between the first and second digits and extended into the first intermetatarsal space in a polypoid fashion. Radiographically, there were no osseous structures associated with the mass, and preliminary biopsy results showed no evidence of malignancy.

Pulmonary carcinosarcoma initially presenting as invasive aspergillosis: a case report of previously unreported combination.

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.

Value of fine-needle aspiration biopsy in initial evaluation of floor of the mouth masses: report of a case of low-grade mucoepidermoid carcinoma.

Low-grade mucoepidermoid carcinoma (LG MEC) is a rare tumor which can occur in the minor salivary glands as intraoral lesion, more frequently in the palate and very rarely in the floor of the mouth. Traditionally, the diagnosis has been made on surgical resection specimens only. There is new growing evidence that these lesions can be accurately diagnosed by a fine-needle aspiration (FNA) biopsy procedure.

Sentinel lymph node mapping technique in colon cancer.

Current conventional surgical and pathological techniques substantially understage colon cancer. This is evidenced by the fact that a significant subset of patients who are stage I and II at the time of colectomy return with distant metastases and ultimately succumb to the disease within the next 5 years. The identification of more nodes within a specimen and the detailed analysis of lymph nodes with advanced pathological techniques such as immunohistochemistry and reverse-transcriptase polymerase chain reaction (RT-PCR) can improve the staging of colon cancer, but are also associated with tremendous financial, time, and labor constraints.

Small early tubular adenomas and mixed colonic polyps found on screening flexible sigmoidoscopy do not predict proximal neoplasia in males.

Background & Aims: Distal colonic adenomas found on flexible sigmoidoscopy are associated with proximal neoplasias, thus requiring a complete colonoscopic examination, but data regarding the association of distal mixed polyps with proximal neoplasia are lacking. We conducted this study to elucidate the significance of distal mixed colonic polyps in predicting proximal neoplasia.

Methods: We retrospectively analyzed data from patients who underwent a flexible sigmoidoscopic examination for colorectal cancer screening and a follow-up colonoscopic examination because of distal colonic polyps.
