Chordomas of the tip of the tail in 6 ferrets were examined using histopathological, histochemical and immunohistochemical procedures. Histopathologically, round neoplastic cells containing numerous cytoplasmic vacuoles of varying sizes, categorized as "physaliphorous cells", were observed in the amorphous eosinophilic or pale basophilic myxoid stroma. Physaliphorous cells were arranged in lobu...

We report two cases of follicular adenoma of the thyroid with extensive extracellular mucin deposition. Fine needle aspiration in Case 1 showed singly discohesive polygonal cells in a granular mucinous background. They contained abundant eosinophilic cytoplasm, nuclear irregularities, and frequent nuclear inclusions with occasional bizarre mitoses. A right lobectomy was done. In Case 2, a 47-ye...

Hyalinizing clear cell carcinoma (HCCC) is very rare in the oral cavity, arising more frequently in the minor salivary glands. We present the case of a 57-year-old woman with a swelling on the anterior palatoglossal arch of 2x1 cm size. An incisional biopsy was taken and histological examination revealed typical clear cells arranged in anastomosing trabeculae, cords, nests, and solid sheets wit...

Diagnosis: Disseminated histoplasmosis. Although disseminated histoplasmosis occurs episodically in the United States, it is possible that the patient we describe may have acquired the infection during his residence in Panama, which is an area of high endemicity. In 1905, Samuel Darling, a University of Maryland graduate who was stationed in Panama as a US Army pathologist, was the first invest...

Mucoepidermoid carcinoma of the bile duct is a rare entity. Only one mucoepidermoid carcinoma from the common bile duct has been reported in the Korean literature. Herein, we present the first in the English literature. The tumor arose in the intrapancreatic (distal) common bile duct in an 83-year-old woman who presented with obstructive jaundice and elevated liver enzymes. The tumor invaded th...

Background Knowledge regarding any variations related to the morphology, relations of the pancreas is imperative for a surgeon operating on this region. Cadaveric observations are considered to be the base for clinical investigations and hence this morphohistological study of the unusual, grooved pancreas with its unique presentation was undertaken in an adult cadaver. Materials and method Abdo...

Pleural mesothelioma has been diagnosed in 52 patients in three hospitals on Merseyside between 1955 and 1970, 60% being diagnosed from operation specimens and the rest from postmortem tissues. Necropsies eventually held on nearly half the operation cases confirmed the diagnosis, giving a necropsy rate of 70% for the series. The morbid anatomy conformed to earlier descriptions except that wides...

Proteus syndrome (PS) is a severe, variable, and rare disorder with asymmetric and disproportionate overgrowth of body parts, cerebriform connective tissue nevi, epidermal nevi, dysregulated adipose tissue, and vascular malformations. It is associated with benign and occasionally malignant tumors. We report the first case of ductal carcinoma in situ (DCIS) in a 28-yr-old woman with PS who under...

Copyright © 2007 by the International Association for the Study of Lung Cancer S808 Coexistence of MALT lymphoma with carcinomas was seen primarly in gastric lesions associated with H. Pylori infections. To our knowledge only one case was reported with synchronous pulmonary adenocarcinoma and MALT type extranodal marginal zone lymphoma. Case Report: A 49 years old male presented with back pain,...

A 42-year-old man with no significant medical history presented to the emergency department with headaches and fever of three weeks duration. He had returned to the United States from a recent trip to Puerto Rico, where he reported multiple unprotected sexual contacts with men. One week prior to presentation, he was evaluated at an outside facility and was discharged with a diagnosis of Dengue ...
