Alveolar soft part sarcoma (ASPS) is a rare but distinct soft tissue tumor with unique histopathological and electron microscopic features. Orbital involvement is rare with only few reports published in the literature. ASPS have an indolent clinical course, but it is known to metastasize. Primary modality of treatment is surgery followed by adjuvant treatment. This case is a unique presentation with orbital mass with on and off bleeding. This is the largest orbital ASPS for which orbital exenteration was performed...

BACKGROUND: Rab(3)8 small GTPase regulates intracellular transport in melanocytes and alveolar type II epithelial cells. Ruby rats carrying Rab(3)8 and other gene mutations exhibit oculocutaneous albinism, bleeding diathesis, and hence, are a rat model of human Hermansky-Pudlak syndrome (HPS). We previously showed that Long Evans Cinnamon (LEC) rats, one strain of the Ruby rats, developed aberrant lung surfactant homeostasis with remarkably enlarged lamellar bodies in alveolar type II cells...

Severe leptospirosis can be a rare cause of acute respiratory distress syndrome (ARDS) and multiorgan failure. A patient who made an impact on how I practice was a case of severe leptospirosis (Weil's disease) that presented as ARDS in the ICU. Leptospirosis is an under-reported infectious disease worldwide and should be considered as a cause of ARDS especially in patients with exposure history complicated with diffuse alveolar bleeding (DAH), icteric hepatitis and renal deterioration. Empiric treatment should be recommended before confirmation of laboratory tests as serological diagnosis is time consuming...

Resection of a prominent mandibular angle is commonly used in Eastern society to improve the lower one third facial proportion. Historically, this procedure had a high complication rate, such as severe bleeding, asymmetry of the angle reduction, and "second mandibular angle." A safer and more effective way of performing such procedures is needed. The aim of this study is to introduce 3 instruments, a tunable guide handpiece, milling cutter, and flywheel, which were invented by the author, as well as a related ostectomy technique for correcting prominent mandibular angles using a modified full-thickness marginal ostectomy of the mandibular corpus angle, named the "stamp perforation" technique...

Ectodermal dysplasia (ED) is an inherited disorder characterized by abnormality of ectodermally derived structures. A recurrent oral finding is oligodontia, which in turn leads to a severely hypotrophic alveolar process with typical knife-edge morphology and adverse ridge contours. This unfavorable anatomy can seriously hamper proper implant placement. Fresh-frozen bone (FFB) allografts recently have been proposed to augment the residual bone volume for implant placement purposes; however, scientific evidence concerning the use of FFB to treat ED patients is absent...

Diffuse alveolar hemorrhage (DAH) is a life-threatening complication that occurs in association with various diseases including coagulation disorders. In rare cases, it is caused by hemophilia. A 48-year-old man was admitted to our hospital for a third time due to DAH. Although the cause of DAH could not be identified by bronchoscopy or laboratory tests, a good response to corticosteroids suggested idiopathic DAH with pulmonary capillaritis. The patient was diagnosed with hemophilia B based on the results of a detailed inquiry, a mildly prolonged activated partial thromboplastin time, and low factor IX activity...
