Hydatid disease, caused by larval stage of Echinococcus granulosus, is a common parasitic infection of human and animal. Although liver and lung are the most commonly affected area, hydatid cyst may develop any part of the body. Primary subcutaneous hydatid cyst is extremely rare. We report a case of 54 years old man who presented with palpable mass in scapular region from 3 years ago....

Background: Pneumomediastinum (PM) is caused by alveolar rapture. If air leak persists, subcutaneous emphysema occurs. The PM and subcutaneous emphysema have various etiologies. Common causes are respiratory tract infections and asthma exacerbations. Rarely, the PM occurs secondary to foreign body aspiration, and the life-threatening complications will occur without proper treatment. Case repo...

Background Extraskeletal Ewing's sarcoma is a rare malignant tumor of mesenchymal origin, which is histologically similar to primary osseous Ewing's sarcoma. It has been well described in deep soft tissues. However, location in cutaneous or subcutaneous tissue has rarely been reported. Being seen principally in children, it can be seen, rarely, in old men. Case report We present a case of sub...

Subcutaneous emphysema is the novo infiltration of air in subcutaneous layer skin. The incidence varies from 0.43% to 2.34%. and can result surgical, traumatic, infectious, or idiopathic processes. Air enter tissue through occupational accidents, as occurred our clinical presentation; on physical examination, most common finding associated with crepitus palpation. It important make a timely dia...

Subcutaneous tissue emphysema is observed in a several clinical settings but spontaneous subcutaneous emphysema in the absence of pneumothorax with broncho pleuro subcutaneous fistula is rare. We report a case of spontaneous subcutaneous emphysema secondary to cavitary pulmonary tuberculosis in the absence of pneumothorax.

Introduction:Spontaneous pneumomediastinum, pneumothorax, and subcutaneous emphysema are rare, but serious complications of inflammatory myopathies and occur more commonly in DM than PM. complications of dermatomyositis (DM) and polymyositis (PM), both of which can be fatal. Case Report:A 20-year-old woman was admitted with neck pain, dyspnea, cough, and fever.

Subcutaneous administration of biotherapeutics offers several potential advantages compared with intravenous administration. Many biotherapeutics, both marketed or in development, are administered via the subcutaneous route. This minireview provides an overview of the presystemic absorption processes following subcutaneous administration, the resulting pharmacokinetics after subcutaneous admini...
