The histological features of 168 lesions of Kaposi's sarcoma from 159 patients in Malawi, where the disease is commoner than elsewhere, were characteristic. All showed well-developed areas of tumour and could be grouped fairly readily into those with a mixed pattern, a predominantly spindle cell pattern, and an anaplastic group, though intermediate patterns were seen. Hyaline bodies were presen...

The treatment of focal full thickness articular defects in the knee has continued to present a challenge, with no traditional treatment method providing consistent acceptable long-term clinical results. Patients with significant chondral defects frequently have persistent joint line pain, swelling, and catching in the knee. In contrast to marrow stimulation treatment techniques, such as abrasio...

castleman’s disease (angiofollicular lymphoid hyperplasia) includes a heterogeneous group of lymphoproliferative disorders. the cause of this disease remains uncertain. there are two types of localized castleman’s disease: the more common hyaline vascular and the plasma cell types. mixed variant is an uncommon localized lesion in general population. the lesions can occur in any part of the body...

Alflutop is the standardized sterile extract of marine fish, similar in composition to matrix hyaline cartilage, manufactured by Biotehnos S.A. (Romania). The question effectiveness aflutop remains relevant.

The presence of hyaline eosinophilic inclusions in protoplasmic astrocytes of cerebral cortex is a rare finding that is mostly associated with history of intractable epilepsy and cases of Aicardi syndrome. Here, we describe a 17-year-old male who presented with a longstanding history of intractable epilepsy. Microscopic examination of the excisional biopsy of the epileptic focus showed hyaline ...

INTRODUCTION Costochondral cells may be isolated with minimal donor site morbidity and are unaffected by pathologies of the diarthrodial joints. Identification of optimal exogenous stimuli will allow abundant and robust hyaline articular cartilage to be formed from this cell source. METHODS In a three factor, two level full factorial design, the effects of hydrostatic pressure (HP), transform...

BACKGROUND Recently, several animal studies have found that spontaneous hyaline cartilage regeneration can be induced in vivo within a large osteochondral defect by implanting a synthetic double-network (DN) hydrogel, which is composed of poly-(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) and poly-(N,N'-dimethyl acrylamide) (PDMAAm), at the bottom of the defect. However, the effect of hyd...

High-grade osteochondral lesions cause pain, functional limitations, and oftentimes require surgical treatment. Described operative interventions include microfracture, autograft transfers, allograft transplantation, autologous chondrocyte implantation, matrix assisted implantation. Another option for recalcitrant cartilaginous defects is particulated juvenile cartilage (PJAC) Short-term studie...

Expanded costochondral cells provide a clinically relevant cell source for engineering both fibrous and hyaline articular cartilage. Expanding chondrocytes in a monolayer results in a shift toward a proliferative, fibroblastic phenotype. Three-dimensional aggregate culture may, however, be used to recover chondrogenic matrix production. This study sought to engineer a spectrum of fibrous to hya...
