We report a case of clear cell carcinoma (CCC) of the ovary with plasma cell-rich inflammatory stroma, a recently proposed subtype of CCC, and present the cytological findings. The patient was a 48-year-old woman, who was incidentally found to have a right ovarian tumor during the preoperative work-up for an early-stage adenocarcinoma of the uterine cervix. Cytological examination of an imprint smear of the ovarian tumor and peritoneal washing revealed solid cell clusters of irregular, often dendritic shapes, which were intermingled with many inflammatory cells...

INTRODUCTION: Neonatal respiratory distress (NRD) is a main cause of neonatal morbidity and mortality in developing countries. Early detection of its risk factors and early treatment of its etiologies are major challenges. However, few studies in developing countries have provided data needed to tackle it. We aimed to determine the prevalence, predictors, etiologies and outcome of NRD in a tertiary health care centre of Cameroon. METHODS: We analyzed the hospital files of all newborns admitted to the Neonatal unit of Douala General Hospital from 1(st) January 2011 to 28(th) February 2013...

Although Ultrananocrystalline diamond (UNCD) has been proposed as a coating material for titanium biomedical implants, the biological effects and toxicity of UNCD particles that could eventually detach have not been studied to date. The biokinetics and biological effects of UNCD compared to titanium dioxide (TiO2 ) nanoparticles was evaluated in vivo using Wistar rats (n = 30) i.p. injected with TiO2 , UNCD or saline solution. After 6 months, blood, lung, liver, and kidney samples were histologically analyzed...

Ligneous conjunctivitis represents a very rare form of chronic membranous conjunctivitis, with unknown etiology; less than 200 cases have been reported in the literature, most of them in infants and children. After 40 years, this condition appears in exceptional circumstances. We present, in this study, two patients (of 55 and 64 years old) with very severe forms of ligneous conjunctivitis, certified by histopathological examination, one of them being previously diagnosed with Lyell's syndrome. The histological examination in ligneous conjunctivitis is important for diagnostic but also to elucidate the etiopathological context...

Cylindromas are uncommon benign adnexal tumor. Multiple cylindromas are commonly genetically inherited and also known as "turban tumor." Cytology of dermal cylindroma is rarely discussed in previous literature. We have diagnosed a case of dermal cylindroma of scalp in an elderly female patient by fine needle aspiration cytology of the lesion and further confirmation was done by histopathology. Cytology consists of many clusters of small round to oval basaloid cells surrounded and attached with magenta coloured acellular hyaline material...

Primary epithelioid sarcoma of bone is extremely rare with only two reported cases in the English literature. A previously healthy 18-year-old male presented with a six-month history of right facial numbness and tingling and right eye diplopia. CT scan revealed an ill-defined mass with dense osseous matrix centered in the right zygomatic bone. An outside biopsy was read as osteosarcoma. The resection specimen revealed large epithelioid and spindle cells embedded in a prominent hyalinized matrix with focal metaplastic bone formation...

To date, 20 species of Parastenocarididae are known from the Indian subcontinent. This paper gives the description of two more new species from the coastal deltaic belt of the Rivers Krishna and Godavari in the Andhra Pradesh state of the southeastern Indian peninsula. They are: Parastenocaris enckelli n. sp. from a hyporheic habitat, and Dussartstenocaris bisetosa n. sp. from a farm bore. Parastenocaris enckelli belongs to the brevipes-group of the genus Parastenocaris Kessler, 1913 sensu Lang 1948 and Reid 1995, and is characterized by the following features: the male leg 4 basal complex consists of a large chitinized plate, with two digitiform hyaline structures at its proximal outer corner of the anterior surface, and one smooth, moderately strong, claw-like spine at the inner distal corner of basis; the endopod of the same leg is membranous, with bulbous proximal part having a diagonal row of three spinules, and its distal part is drawn out into smooth pointed structure; and the male leg 3 ancestral proximal segment is subproximally dilated, elongate, with ladle-shaped apophysis, which is slightly longer than the spiniform thumb...

PURPOSE: Compared to the ligamentum flavum (LF), morphology of the epidural membrane (EM) and the periradicular fibrous tissue (PRFT) has been largely ignored in studies of lumbar spinal stenosis (LSS). The aim of this prospective study was to elucidate the morphologies and clinical importance of the EM and PRFT in LSS. METHODS: Before starting this study, neural compressive EM (c-EM) and PRFT (c-PRFT) were defined as follows based on our microsurgical experience and a literature review...

A 2-month old foal with septic shock and severe respiratory distress was referred to the Veterinary Teaching Hospital. Due to poor prognosis, the foal was euthanized. Histopathology showed lesions suggestive of Rhodococcus equi infection associated with a diffuse interstitial infiltrate of foamy macrophages and syncytial cells presenting large acidophilic intranuclear inclusion bodies, fibrin exudates and hyaline membranes. Bacteriological examination from lung and respiratory exudates confirmed R. equi infection, whilst immunohistochemistry and PCR yielded a positive result for Equid herpesvirus type 1(EHV-1)...

G proteins play essential roles in regulating fetal lung development, and any defects in their expression or function (eg, activation or posttranslational modification) can lead to lung developmental malformation. Geranylgeranyl diphosphate synthase (GGPPS) can modulate protein prenylation that is required for protein membrane-anchoring and activation. Here, we report that GGPPS regulates fetal lung branching morphogenesis possibly through controlling K-Ras prenylation during fetal lung development. GGPPS was continuously expressed in lung epithelium throughout whole fetal lung development...

We report 2 cases of primary dermal osteosarcoma. The patients were an 88-year-old man and a 72-year-old man complaining of masses occurring in the ear pavilion and the palm, deemed suspicious for basal cell carcinoma and metastatic colonic carcinoma, and were treated by resection. Microscopically, both featured a dermal lesion mostly composed of atypical spindle cells within a fibrous to hyaline matrix often showing mineralization. Osteoid material was rimmed by atypical tumor cells and was also associated with osteoclast-like giant cells...

The treatment of joint related diseases often involves direct intra-articular injections. For rational development of novel delivery systems with extended residence time in the joint, detailed understanding of transport and retention phenomena within the joint is mandatory. This work presents a systematic study on the in vitro permeation, penetration and accumulation of model polymers with differing charges and molecular weights in bovine joint tissue. Permeation experiments with bovine synovial membrane were performed with PEG polymers (6-200 kDa) and methylene blue in customized diffusion chambers...

BACKGROUND: Atypical uterine leiomyomas show benign behavior. However, the distinction between leiomyomas and leiomyosarcomas may at times be problematic. We report a rare case of atypical uterine leiomyoma. We try to investigate potential immunohistochemical parameters that could be essential to distinguish cases of malignant smooth muscle tumors and those of uncertain or borderline histology. CASE PRESENTATION: A 56-year-old white ethnic Albanian woman from Kosovo presented with uterine bleeding because of uterine multiple leiomyomas...
