littoral cell angioma is a splenic vascular tumor of splenic sinus lining cells that is considered benign in general. this report describes a case of littoral cell angioma with no malignant histological features. the lesion is composed of anastomosing vascular channels resembling splenic sinus; they are lined by endothelial cells which show mitotic activity very rare. immunohistochemically, the...

PURPOSE To study the morphologic characteristics of the optic nerve (ON) by using an experimental model of knockout mice for the expression of the PTEN gene, mainly involved in cell cycle arrest, apoptosis control, and cell size regulation. METHODS The eyeballs with the retrobulbar ON attached were obtained from 26-week-old mice. By using morphologic and morphometric techniques, light and ele...

acinic cell carcinoma arising in salivary glands is a rare tumor, accounting for 2% to 5% of the primary neoplasms of the parotid gland. when these tumors are well-differentiated, the neoplasia has innocuous aspect, due to the similarity to normal parotid tissue. this makes the diagnosis difficult. initially the malignancy of this tumor was uncertain; however, recent studies have declared it as...

[1] The geologic origin of the Medusae Fossae Formation (MFF) has remained a mystery despite three decades of research. To better constrain its formation, an in-depth analysis of observations made in the literature was combined with a new survey of over 700 Mars Orbiter Camera narrow-angle images of the MFF to identify morphologic characteristics and material properties that define this formati...

Morphologic variability from 25 populations of Acer campestre L. in Bosnia and Herzegovina was analyzed. Morphometric structure between-population performed based on 10 fruit-parameter characteristics 19 leaf-parameter using multivariate statistical analysis. Results confirmed the separation three submediterranean as a group relation to other tested populations, which Banja Luka population is d...
