B) Anatomopathology slide stained with hematoxylin and eosin (original magnification x10) of the bladder wall showing massive infiltration by a carcinomatous
proliferation of the epidermoid type arranged in islands, or in broad cords in depth (arrows).
In most tumors, equal proportions of carcinomatous
and sarcomatous elements have been observed.
In contrast to MA, malignant mullerian mixed tumours (MMMT) typically have a high grade mesenchymal component and an invasive carcinomatous
In these 2 groups, extensive sampling may demonstrate definitive carcinomatous
components that support the classification as a carcinoma but are sufficiently focal as to be excluded from the pleomorphic carcinoma group.
(7.) Perzin KH, Bridge MF.Adenomatous and carcinomatous
change in the small intestine.
(Immunohistochemical [IHC] studies showed nonspecific staining for myoglobin and were negative for myogenin and myo-D1.) Treatment response was moderate and primarily affected the carcinomatous
Today, it is well-known that the interaction between stroma and carcinomatous
epithelial cells plays an important role in carcinogenesis, cancer progression and metastases (3).
A strange feature of this tumor is the relative scarcity of the carcinomatous
Because most FNH are asymptomatic and are without carcinomatous
change, nonoperative therapy is the standard treatment.
Neoplasms may spread into the subarachnoid space and produce enhancement of the brain surface and subarachnoid space, a pathologic process often called "carcinomatous
infiltration of squamous cell carcinoma was observed in the excisional biopsy of the lesion.
In the presence of malignant tumor proliferation of spindle-cell sarcomatous aspects, a carcinomatous
component should always be sought to eliminate the diagnosis of sarcomatoid carcinoma.
polyarthritis (CP) is associated with various solid tumors and can present similar to seronegative rheumatoid arthritis with symmetric involvement of hands, wrists with morning stiffness, or as an asymmetric migratory polyarthritis .
Immunohistochemically, the malignant carcinomatous
cells stained positive for cytokeratin 7 (CK-7) (Figure 3(b)).
Diagnostic lumbar puncture was performed the next day, which revealed carcinomatous
cells of ovary origin in the cerebrospinal fluid (CSF) (Figure 1).
