E, Another example of p63-positive PCa exhibits atrophic cytoplasm with a basaloid morphology often seen in these carcinomas; infiltrative
architecture and nuclear atypia is retained.
Although, in our case, the infiltrative
appearance of the lesion in CT and the medial location of the kidney mass, we were technically hampered in performing the biopsy.
4) Rather than being infiltrative
, the tumors are well defined and tend to compress adjacent neural tissue.
The tumour grew aggressively and, 4 weeks later, the uncontrasted CT brain image (not included) showed subependymal infiltrative
tissue that markedly enhanced with contrast (Fig.
The tumors evaluated in the study typically had an infiltrative
pattern with dermal fibrosis or sclerosis: 61% showed elastosis, while 30% were ulcerated.
Histologic examination revealed infiltrative
neoplasia comprising small hyperchromatic cells with round, eccentric nuclei and sparse eosinophilic cytoplasm of rhabdoid appearance (Fig.
It is debatable and has not been shown that microscopic endometriosis ever progresses to deep infiltrative
While maximizing infiltrative
surface area, the chamber also offers a 20-degree integral articulating joint that is ideal for either straight or contoured septic leach field applications.
Tumors are poorly circumscribed with an infiltrative
border, including extracapsular extension beyond the salivary gland; the neoplastic cells show significant perineural (figure 2) and lymphovascular invasion.
The patient, admitted for infiltrative
cardiomyopathy, experienced kidney failure and heart failure despite therapy to reverse his condition.
A contrast-enhanced computed tomographic (CT) scan showed an infiltrative
mass arising from the lower pole of the right kidney without any nodal involvement.
On microscopy, sections showed interlacing fascicles of spindled cells with diffuse pleomorphism (Figure 2a), increased mitotic activity (up to 16 mitoses per 10 HPF with atypical forms) (Figure 2b), and a focally infiltrative
