Warthin tumor-like papillary thyroid carcinoma is an uncommon variant of papillary thyroid carcinoma. We report a rare case of Warthin tumor-like variant of papillary thyroid carcinoma with a dedifferentiated component consisting of a solid tumor area composed of neoplastic cells with a spindle to tall cell morphology associated with marked nuclear pleomorphism, atypical mitoses, and foci of ne...

Ovarian borderline serous tumors are uncommon. Combination of borderline serous adenofibromatous tumor and prominent micro papillary architecture is not previously reported. We report a case of borderline papillary serous adenofibromatous tumor (also called serous adenocarcinofibroma) with extensive micropapillary pattern in a 27 year-old married woman. She was infertile and presented with diff...

BACKGROUND The rupture of the anterolateral papillary muscle is less common than the posteromedial papillary muscle since the anterolateral muscle has dual blood supplies, while the posteromedial papillary muscle has a single blood supply. CASE PRESENTATION We present a case report of a 42 year old male presenting with heart failure being diagnosed to have mitral regurgitation from the partia...

The objective of this study was to describe a simple and reproducible papillary-ventricular complex technique for repairing functional mitral regurgitation. To avoid a recurrence of mitral regurgitation subsequent to left ventricular remodelling, we performed papillary muscle plication and papillary muscle and head approximation in combination with relocation of the papillary muscle heads to co...

Various structural anomalies of the left ventricular papillary muscles have been observed in recent years. Many of these have been linked to electrocardiographic aberrations. Recently two reports have appeared where the base of the posterior papillary muscle was identified as the source of frequent premature ventricular complexes. In some of these patients these frequent premature ventricular c...

Papillary fibroelastoma is the most common primary cardiac valvular tumor. Historically, papillary fibroelastoma was an incidental autopsy finding, deemed to have no clinical significance. More recently, reports of symptomatic cases of papillary fibroelastoma with complications such as myocardial infarction and stroke have led papillary fibroelastoma to be considered a potentially dangerous les...

The left ventricular papillary muscles appear to be the last portions of the heart to be perfused by coronary arterial blood. As a consequence they are sensitive anatomic markers of myocardial ischemia. Foci of necrosis or fibrosis therefore are commonly seen in these structures, particularly the posteromedial papillary muscle, which has a poorer blood supply than does the anterolateral muscle....

During ischemia, lidocaine or quinidine may prevent arrhythmias by blocking conduction without suppressing abnormal automaticity. The purpose of this study was to determine whether lidocaine or quinidine (5 Mg/ml) produced Purkinje fiber-papillary muscle block during superfusion in vitro with an altered Tyrode's solution containing some components of ischemia: 6 mM potassium, Po2 < 40, pH = 6.8...

The World Health Organization (WHO) defines intracholecystic papillary neoplasms (ICPNs) as gallbladder lesions of intraductal the bile duct (IPNB). We present a case ICPN that was incidentally diagnosed following cholecystectomy for cholecystitis and cholelithiasis. Abdominal ultrasonography computed tomography showed thickening wall cholelithiasis but were not specific tumor. Histopathologica...

Alias Renal papillary adenoma Tubulo-papillary adenoma Note The concept of renal papillary adenoma is a controversial one, and has evolved over the past 3 decades. The term has historically been used to refer to small proliferations of papillary or tubulo-papillary epithelium in the renal cortex which theoretically have no metastatic potential. The size criterion in this definition is somewhat ...
