The pulmonary venules then drain toward the periphery of the lobule and form pulmonary veins that travel within the interlobular septa.
One glandular structure reminiscent of a mammary lobule was identified in the deep dermis adjacent to the tumor.
The soft tissue chondroma4 presents with well-defined lobules of hyaline cartilage, usually in association with a tendon or a tendon sheath and most commonly in the distal extremities.
On microscopic evaluation, the majority of the thymus retained its usual lobular architecture and exhibited both cortical and medullary hyperplasia, with high cellularity and minimal fatty infiltration.
The cut surface was tan-brown and partially lobulated by fibrous septa and did not show necrosis or cystic changes.
An abdominal computed tomographic scan showed the presence of a lobulated pelvic mass arising from the right lower uterine segment, with left lateral displacement of the bladder.
A chest radiograph revealed complete opacification of the left lower thorax with a small amount of aerated lung above and a lobulated mass in the right middle lobe.
Other areas were densely cellular with a lobular infiltrate of plump endothelial cells surrounding small capillaries.
The remaining glomeruli showed lobular accentuation of the glomerular tufts secondary to diffusely increased cellularity, thickened capillary loops, and excess accumulation of mesangial matrix.
Cut section revealed a gray-tan, fleshy, and lobulated surface with fine septa between the lobules and foci of degeneration and necrosis.
