Primary Thyroid Lymphoma: A Retrospective-Observational Study in a Single Institutional Center.

: primary thyroid lymphoma (PTL) is a rare neoplasm, displaying a variety of histological features. It is often a challenge for pathologists to diagnose this tumor. : this study is a retrospective analysis of clinical and pathological characteristics of a group of eleven patients (eight women and three men, mean age 68 years, range 50-80 years) diagnosed with PTL.

Collision Tumors of the Colon and Peritoneum: Signet-Ring Cell Carcinoma and Granular Cell Tumor.

Collision tumors, although rare, characterized by two distinctive (morphological, as well immunohistochemical) and spatially independent tumor components at the same location, are always puzzling for clinicians, pathologists, and patients because they do not fit into the usual approaches, being neither diagnostic nor therapeutic. Reviewing the specialized literature, to date, collision tumors have been reported in multiple locations such as the skin, esophagus, stomach, intestine, liver, kidney, bladder, adrenal gland, or thyroid. We report a case of coexistence at the same site of a malignant tumor of the ascending colon and a benign tumor emerging from the peritoneal lining, initially thought by the surgeon to be right-sided serosal carcinomatosis.

Nasal polyposis from cystic fibrosis in children - the experience of a single center.

Background: Cystic fibrosis (CF) is the most common monogenic disease, characterized by clinically notable polymorphism. Respiratory disease is the main factor that influences the disease outcome and prognosis of the patient with CF, bacterial infections being responsible for severe exacerbations and rhinosinusitis a difficult complication, besides lung disease.

Aim: The aim of the paper was to present a case series of CF-associated nasal polyposis and our management experience, providing new data for nasal and sinus complications.

Clinical and morphological aspects of lateral femoral condyle status after an osteochondral fracture. A case report.

Although osteochondral fractures of the lateral femoral condyle are uncommon, fixation of the fragments is recommended, mostly when is about young athletes with such post-traumatic pathology. We present a case of a professional handball player teenager female, with a lateral femur condylar osteochondral fracture after a fall with the right knee in extension and in internal rotation. Magnetic resonance imaging (MRI) showed an osteochondral fracture of the lateral femoral condyle, 34.

Lymphoproliferative disorder in a twin female teenager post kidney transplantation.

Post-transplant lymphoproliferative disorder (PTLD) is defined as a heterogeneous group of lymphoid and plasmocytic proliferations with variable malignant potential. They often arise in immunocompromised post solid organ transplant (SOT) patients linked with Epstein-Barr virus (EBV) infection. Clinical manifestations include fever, lymphadenopathy and organ involvement.

Evaluation of normal and pathological Achilles tendon by real-time shear wave elastography.

Tendinopathy covers a range of several tendon conditions, mostly caused by overuse but at least in Achilles tendon pathology, favored by obesity, diabetes, inflammatory and autoimmune conditions. Subclinical tendon pathology is difficult to diagnose, as magnetic resonance imaging (MRI) examinations are sometimes inconclusive and not cost-effective. Elastography is an ultrasound examination method that uses mechanical impulses to produce shear waves in the tissue of interest, then measures the tissue displacement and calculates the shear wave speed or the elastic modulus of the examined tissue.

Clinical and color Doppler imaging features of one patient with occult giant cell arteritis presenting arteritic anterior ischemic optic neuropathy.

Anterior ischemic optic neuropathies (AIONs) represent a segmental infarction of the optic nerve head (ONH) supplied by the posterior ciliary arteries (PCAs). Blood supply blockage can occur with or without arterial inflammation. For this reason, there are two types of AIONs: non-arteritic (NA-AION), and arteritic (A-AION), the latter is almost invariably due to giant cell arteritis (GCA).
