septum

Histopathological evaluation showed a neoplasm composed of cells arranged in nesting (Zellballen) pattern separated by thin fibrovascular septae. The tumour cells were round to polyhedral with moderate amount of eosinophilic granular cytoplasm.

Multiple septae were visualized in the mass; some of them were thick and irregular and showed contrast uptake.

Lung sections examined from the control animal had moderate lymphoplasmacytic interstitial pneumonia characterized by a diffuse thickening of alveolar septae by moderate numbers of lymphocytes, plasma cells, polymerized fibrin, and edema fluid.

For septal thickness, the thickness of the dominant type of septae in each specimen was scored.

CCH is the first and only investigational injectable treatment designed specifically to reduce the appearance of cellulite by disrupting the collagen structure of fibrous septae, which cause dimpling of the skin.

In the liver tissue of the control group, moderate and severe fibrosis, thick fibrous septae of the false lobule, heavy degree of hepatocyte degeneration and necrosis, and many fat vacuoles could be seen under the microscope (Figure 4A).

The main US findings for this condition are swelling of the salivary glands, which are more prominent in the submandibular glands, as well as internal hypoechoic septae formation in the glands with no increase in gland vascularity [3,4].

The dividing septae are generally diminutive, containing the narrow branches of an extensive network of subepithelial vessels.

"Cellulite is caused by tiny connective tissue filaments (called fibrous septae) that anchor the skin to the underlying tissue and have fat in between," explains Dr Nick Rhodes.

On fat-suppressed T2-weighted (FS-T2) or short tau inversion recovery (STIR) images, liposarcomas typically have hypertense septae whereas lipomas have hypointense septae (15).

Histopathology showed tumor located in the dermis consisting of lobules separated by fibrovascular septae. Within the lobules, tubular lumina of various sizes, cystic spaces and many proliferating blood vessels are noted.
