Effects of Delayed Hypothermic Machine Perfusion on Kidney Grafts with a Preliminary Period of Static Cold Storage and a Total Cold Ischemia Time of Over 24 Hours.

BACKGROUND Hypothermic machine perfusion (HMP) appears to exert a reconditioning effect on the ischemic damage of kidney grafts. However, some concerns still remain about its real effectiveness when it is delayed after a preliminary period of static cold storage (SCS) or with prolonged overall cold ischemia time (CIT). MATERIAL AND METHODS The effect of HMP on hemodynamic, metabolic, histological and ultrastructural features of grafts was investigated in 21 single-kidney grafts treated with a delayed HMP after SCS and with a total CIT of over 24 h.

Second Surgery in Insular Low-Grade Gliomas.

Background: Given the technical difficulties, a limited number of works have been published on insular gliomas surgery and risk factors for tumor recurrence (TR) are poorly documented.

Objective: The aim of the study was to determine TR in adult patients with initial diagnosis of insular Low-Grade Gliomas (LGGs) that subsequently underwent second surgery.

Methods: A consecutive series of 53 patients with insular LGGs was retrospectively reviewed; 23 patients had two operations for TR.

Primary cutaneous nevoid melanoma with Homer-wright rosettes: a hitherto unrecognized variant with immunohistochemical and ultrastructural study.

We report a case of cutaneous nevoid melanoma manifesting as a growing and pruritic pigmented lesion of the back in a 43-year-old woman. The lesion measured 1.2 cm in its largest dimension.

Plasma cell myeloma presenting with diffuse pleural involvement: a hitherto unreported pattern of a new mesothelioma mimicker.

We described 2 cases of plasmacytoma presenting with a preponderant involvement of the pleural membranes simulating clinically, radiologically, and on gross pathologic inspection a primary mesothelioma. The patients were an 80-year-old man and a 45-year-old woman. In both cases, the clinical presentation was that of a serosal tumor, including effusions and pleural thickening.

Eosinophil-rich squamous carcinoma of the oral cavity: a study of 13 cases and delineation of a possible new microscopic entity.

We report 13 cases of squamous cell carcinoma (SCC) of the oral cavity characterized by a prominent eosinophilic infiltration of the stroma. All patients were adults, 10 men and 3 women (aged 54 to 92 years; median, 71 years). They presented with tumors of the gingiva (5 cases), tongue (3 cases), palatine tonsil (2 cases), palate (2 cases), and mucosal aspect of lip (1 case).

Intravesical botryoid adenocarcinoma of the prostate: report of an unusual growth pattern of prostatic carcinoma simulating a urinary bladder tumor.

We report on 3 cases of prostatic carcinoma presenting with a predominant intravesical mass as to simulate clinically and macroscopically a primary tumor of the urinary bladder. The patients were 65, 66, and 68 years old and presented with dysuria and micturition. All patients had a medical history of a prostatic adenocarcinoma diagnosed between 5 and 7 years earlier and treated conservatively.

Russell body gastritis: expanding the spectrum of Helicobacter pylori - related diseases?

We report a new case of Helicobacter pylori gastritis showing plasma cell infiltrates with extensive formation of Russell bodies (Mott cells) within the lamina propria of the antral mucosa. The patient was a 60-year-old woman with a history of epigastric pain. Endoscopy revealed non-specific congestion of the mucosa.

Solitary fibrous tumor of the spinal cord: a clinicopathologic study of two cases.

Two cases of solitary fibrous tumor of the spinal cord are described. The patients were two men, 36 and 47 years old. Clinically, they sought medical care because of progressive paresthesias or urinary incontinence caused by a nodular, fairly circumscribed intraspinal tumor of the cervical and thoracic spinal cord, respectively.
