We present here a 32-year-old male with advanced lately diagnosed, right sided retroperitoneal mass, which had been already treated due to progressive muco-cutaneous lesions clinically consistent with psoriasis, during recent four years. The advanced retroperitoneal mass resected surgically and reported as hyaline-vascular castleman disease with a dense focus of coarse calcification, on histopa...

The observation of an inter-attico-tympanic diaphragm in the middle ear (ME) cleft and the functional histology of the mucosa lead to a concept of ME morpho-functional partition. There are two separate compartments: an antero-inferior one, principally devoted to the muco-ciliary clearance function, and a postero-superior one, more devoted to the gas exchange function. With this concept of parti...

A fluorescein-labelled antiserum to human Tamm-Horsfall mucoprotein applied to frozen human kidney sections gave strong specific labelling, mainly of cells of tubules in the outer medulla. By comparison with adjacent serial sections stained for alkaline phosphatase and succinic dehydrogenase, it is suggested that material reacting immunologically as Tamm-Horsfall muco-protein is found particula...

Rhinosporidiosis is a chronic, granulomatous, muco-cutaneous infection caused by Rhinosporidium seeberi . The non-contagious and sporadic in humans, affecting predominantly the mucous membrane of upper respiratory tract. It quite an uncommon condition seldom affects oral mucosa. clinical presentation this cavity can mimic many other conditions. Here, we report unique case recurrent rhinosporidi...

The connective-tissue sheath surrounding the nervous system of Periplaneta americana consists of two layers, the neural lamella and the sheath cells beneath it. The neural lamella is composed of a collagen-type protein and neutral muco-polysaccharide. The sheath cells possess numerous lipochondria and mitochondria; the former consist of phospholipid and some cerebroside. The cytoplasm of the sh...
