Molecular approaches to diagnosis of invasive aspergillosis what we know and what we do not know.

Invasive aspergillosis (IA) are a major complication in immunocompromized patients where can be serious and rapidly fatal. Early diagnosis and early appropriate antifungal treatment is important in reducing mortality and morbidity. But despite many efforts to develop detection methods, the diagnosis of IA still remains challenging and current conventional methods are limited for adequate diagno...

Pigmented purpuric dermatoses.

Pigmented purpuric dermatoses (PPD) are a group of histopathologically similar conditions that are primarily differentiated based on morphology. The basic pathological finding is a lymphocytic perivascular infiltrate with hemorrhage limited to the papillary dermis without fibrinoid necrosis of the vessels. The etiology is unknown; they run a chronic course and are fairly resistant to treatment....

Pigmented Purpuric Dermatoses

The aetiology is unknown but important contributory factors include venous hypertension, exercise and gravitational dependency [2] . Histology shows a perivascular lymphocytic infiltrate of T cells centred on the superficial small blood vessels of the skin, suggesting that cell-mediated immunity plays a part [3] . There is swelling of endothelial cells and narrowing of the lumen. Extravasation ...
