Two cases of meningeal invasion by non-myelomatous plasma cell dyscrasias--a plasma cell leukaemia and an extramedullary plasmacytoma--are described. Both were secretors of IgD paraprotein and both were diagnosed in life, characteristics which we have not found in any other published case of plasma cell leptomeningitis. Analysis of our patients and of another 25 cases suggests as predisposing f...
Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only...
Infantile myofibromatosis (IMF) is a rare tumour with a wide spectrum of disease activity ranging from a solitary cutaneous nodule through to a multicentric form with widespread visceral involvement. It is characterised by its unique ability to spontaneously regress and has a typical histological appearance of actin-positive fibroblasts arranged in whorls or fascicles and vessels in a pericytom...
Previous in vivo and in vitro studies from our laboratory have revealed a line of pharmacological evidence supporting histamine H3 receptor(s) involvement in the control of gastric acid secretion. We have recently extended our studies to the human gastric tumoral cell HGT-1. This cell was found to contain an H3 receptor inhibiting basal and carbachol-stimulated inositol phosphate formation. Fur...
UNLABELLED INTRODUCTION Clival chordomas present with headache, commonly VI cranial nerve palsy or sometimes with lower cranial nerve involvement. Very rarely, they present with cerebrospinal fluid rhinorrhoea due to an underlying chordoma-induced skull base erosion. CASE PRESENTATION A 60-year old Caucasian woman presented with meningitis secondary to cerebrospinal fluid rhinorrhoea. At f...
The paper presents the case of a female patient who was admitted to our department because of prolonged febrile syndrome, altered general status and renal tumoral masses revealed by thoracic and abdominal CT. After thorough histological examination, including immunohisto-chemistry and in situ hybridization studies, we reached the diagnosis of renal pseudotumoral masses due to IgG4-related tubul...
The authors present the case of a patient with a giant cell tumor of the left femoral neck, with adjacent progressive invasion of bone tissue. Initial treatment was done with local curettage and autologous bone graft from fibula, electrocauterization and filling with methyl methacrylate. A local tumoral relapse was present after one year; therefore a new surgical procedure was necessary, with p...
We present an overview of the history, development, technological advancements, current application, and future trends of cranial endoscopy. Neuroendoscopy provides a safe and effective management modality for the treatment of a variety of intracranial disorders, either tumoral or non-tumoral, congenital, developmental, and degenerative, and its knowledge, indications, and limits are fundamenta...
Peripheral T-cell lymphomas (PTCLs) are aggressive tumors in which the current therapy based on multiagent chemotherapy is not successful. Since cytochrome P450 3A subfamily (CYP3A) enzymes are involved in the inactivation of chemotherapy drugs, we hypothesized that CYP3A and P-glycoprotein (MDR1) expression in these lymphomas could result in a poor clinical response. We measured tumoral CYP3A ...
