Basal cell carcinoma (BCC) is the most prevalent cancer in the Western world and its incidence is increasing. The pathogenesis of BCC involves deregulated Sonic hedgehog signaling, leading to activation of the Gli transcription factors. Most BCCs have a nodular growth pattern, and are indolent, slowgrowing, and considered ‘‘low-risk’’ lesions. In contrast, the ‘‘high-risk’’ morphoeic variant, w...

Focal nodular hyperplasia (FNH) and hepatic adenoma (HA) represent the most frequent non-vascular benign liver tumors. They are often asymptomatic. The widespread use of high-resolution imaging modalities leads to an increase of incidental detection of FNH and HA. Physicians are thus increasingly confronted with these formerly rarely recognized conditions, stressing the need for concise but ade...

Patients with giant retroperitoneal liposarcomas are considered at great risks of perioperative complications and require meticulous anaesthetic management. There have been few reports about anaesthetic management of giant retroperitoneal liposarcoma. We present the case of a 66-year-old patient who suffered from a giant retroperitoneal liposarcoma (diameter 45 cm and weigh 4.5 kg), needing a r...

context: to evaluate treatment success and hypothyroidism following main methods of radioiodine therapy of toxic nodular goiter (tng); calculated versus fixed dose and high versus low dose of radioiodine. evidence acquisitions: we searched medline and scopus databases from inception till july 2013, for clinical trials that compared two different methods of radioiodine administration in tng. the...

nodules that reside within the dermis and frequently demonstrate epidermal attachment. Multifocal lobules of varying size and shape exhibit peripheral palisading and central haphazard array of cells.The entire tumor demonstrates an expansile growth pattern. Cystic degeneration or central necrosis may be prominent. Although similar to the nodular variant, micronodular basal cell carcinoma is com...

In patients with chronic hepatitis and continuous inflammation of the liver, fibrosis develops during the course of wound healing, and with recurrent accumulation of scar tissue and regenerative nodular formation, chronic hepatitis progresses to cirrhosis. In untreated patients with chronic hepatitis C infection, which is a leading cause of hepatocellular carcinoma (HCC), the Metavir liver fibr...

Nontuberculous mycobacterial (NTM) pulmonary infections can be quite similar to tuberculosis, both clinically and radiologically. However, the treatment protocol is not similar. Mycobacterium simiae is a rare cause of NTM pulmonary infection. Herein, we aimed to evaluate and compare the computed tomography (CT) scan findings of M. simiae infection in lungs. For this reason, thirty-four patients...

Elephantiasis nostras verrucosa (ENV) is a rare clinical condition associated with chronic non-filarial lymphedema caused by bacterial or non-infectious lymphatic obstruction. A variety of etiologies, including infection, tumor obstruction, trauma, radiation, chronic venous stasis, congestive heart failure, and obesity, can lead to chronic lymphatic obstruction and edema. Mossy papules, plaques...
