Microscopic photo of a thin section of calcareous tufa of Holocene age.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Plasmacytoid urothelial carcinoma (PUC) is a unique variant of invasive urothelial carcinoma characterized by tumor cells that exhibit a striking resemblance to plasma cells, and it is known to have an aggressive behavior.
Transmission electron microscope (TEM) micrograph showing dark melanin granules in a melanocyte (top center) and in several keratinocytes, which, unlike melanocytes, have bundles of keratin filaments
