The tumor is composed of a complex, arborizing
, and interwoven papillary architecture, usually showing hyalinized fibrovascular cores (figure 1).
When urothelial dysplasia is present in conjunction with the narrow mucosal folds and rare arborizing
papillae of a UPUMP, some urologic pathologists will diagnose an "early" noninvasive low-grade papillary urothelial carcinoma, particularly in patients with a history of urothelial carcinoma, as these lesions likely represent a recurrence of the patient's known bladder cancer.
Histopathology was characterized by sheets of neoplastic cells with arborizing
pattern of fibrovascular network.
They lack the characteristic arborizing
vasculature and the areas of hyalinization characteristic of low grade ESS.
Slit lamp examination showed arborizing
conjunctival vessels and dryness in both eyes.
The clear cells with Nuclear Furhmann grade III nuclei, separated by arborizing
capillaries, corresponded to clear cell (Conventional) renal cell carcinoma (Fig-2).
Microscopically, the masses in the coelomic inlet were composed of neoplastic polygonal cells that formed arborizing
, papillary projections overlying a fibrovascular core that contained scattered lymphocytes and plasma cells.
Myxoid/round cell liposarcoma is characterized by large cells, sometimes epithelioid and the presence of a network of arborizing
Hamartomatous polyps revealed typical morphology of Peutz-jeghers polyps with presence of arborizing
smooth muscle bundles in the lamina propria.
