Although infrequently, mucin secretion has previously been reported in papillary renal cell carcinoma. We here investigate the presence of mucin in a series of 93 renal papillary adenomas in 58 patients. Acid mucin was present in four cases (4.3% of the tumors; 6.9% of the patients), in which basophilic mucin secretion was evident with hematoxylin-eosin. To the best of our knowledge mucin secre...

Papillary thyroid cancer is a common endocrine malignancy. Although p21-activated kinase 4 (PAK4) is involved in the development of different types of tumor, its function has not been investigated in papillary thyroid cancer. Here, we identified a role for PAK4 in papillary thyroid cancer progression. Levels of PAK4 and PAK4 phosphorylated at serine 474 correlated significantly with tumor size ...

BACKGROUND Papillary carcinoma is the most common differentiated malignant thyroid neoplasm. The biological course of this cancer is typically indolent with a protracted clinical course. Metastases commonly occur in regional lymph nodes, and distant metastasis is a late and rare occurrence. We report a patient who presented with cerebellar metastasis prior to the diagnosis of papillary thyroid ...

We herein reported a primary pulmonary papillary carcinoma with colloid-like luminal content in the glandular cavity and classic nuclear features such as pseudo-inclusions, intranuclear grooves in the tumor cell nuclei and ground glass nuclei which closely mimics papillary thyroid carcinoma. Meanwhile, lymph node in the left pulmonary hilum was involved and showed similar features to the primar...

Background: Predicting adverse neurovascular complications due to diabetic ketoacidosis (DKA) particularly in children leads to more appropriately management of disease as well as achievement of acceptable patients' survival. Cerebral edema is a life-threatening adverse event following DKA responsible for high mortality rate. Recently, authors have focused introducing new risk assessment tools ...

Intraductal papillary mucinious neoplasm-biliary type is the biliary counterpart of intraductal papillary mucinious neoplasm-pancreatic type. We report a rare case of intraductal papillary mucinous tumor arising from extrahepatic biliary system. The diagnosis was established on histopathological analysis following endoscopic retrograde cholangiopancreatography-guided biopsy. Isolated papillary ...

Cardiac papillary fibroelastoma is a rare benign cardiac tumor that represents less than 10% of all cardiac tumors. Most papillary fibroelastomas are relatively small. Symptoms, if present, are due to flow obstruction or peripheral embolization. The most common sites of origin are aortic and mitral valve surfaces. We present successful surgical resection of a papillary fibroelastoma through the...

conclusions mortality from papillary muscle rupture remains elevated. survival largely depends on the early surgical repair or the replacement of the mitral valve. case presentation a 71-year-old woman presented to an outside hospital complaining of chest pain and shortness of breath. an electrocardiogram was obtained and revealed depression of the st segments from leads v1 to v4. troponin i wa...

the coexistence of medullary thyroid carcinoma (mtc), papillary thyroid carcinoma (ptc) and parathyroid adenoma is an uncommon clinical entity. here, we report a case of mtc, ptc, and parathyroid adenoma diagnosed incidentally on a routine physical examination of the neck for the work-up of diabetes. the patient had neither symptoms of hypercalcemia nor those related to mtc and ptc.

Complications associated with intraductal papillary mucinous neoplasms, such as acute pancreatitis, perforation, and fistula formation, have been documented. Intraductal papillary mucinous neoplasm with intratumoral hemorrhage is rare. To the best of our knowledge, there have been no previous reports of intraductal papillary mucinous neoplasm rupture and bleeding with intra-abdominal hemorrhage...
