neoplastic

 [ne″o-plas´tik]
pertaining to neoplasia or neoplasm.

ne·o·plas·tic

(nē'ō-plas'tik),
Pertaining to or characterized by neoplasia, or containing a neoplasm.

intravascular large B-cell lymphoma

A high-grade non-Hodgkin lymphoma arising in and generally confined to vascular lumina, which usually begins in the skin and CNS and rapidly spreads elsewhere.

Clinical findings
Often begins with fever of unknown origin and nonspecific cutaneous (e.g., plaques) and neurologic complaints.
 
DiffDx
Skin lesions (erythematous/purple plaques on the trunk and lower legs) may be confused with mycosis fungoides, sarcoidosis, vascular neoplasms (e.g., Kaposi sarcoma) or involvement by lymphoma or leukaemia.

Prognosis
Extremely poor; short survival is the norm despite aggressive chemotherapy. The diagnosis is often established postmortem.

polycythemia

Any ↑ RBC mass. See Relative polycythemia, Secondary polycythemia.
Polycythemia types
Relative RBC mass is above normal but not pathologic. See Relative polycythemia.
Secondary to various physiopathologic mechanisms, usually hypoxia or ↑ erythropoietin secretion
Neoplastic, ie polycythemia vera, see there  . ;.

ne·o·plas·tic

(nē'ō-plas'tik)
Pertaining to or characterized by neoplasia, or containing a neoplasm.

neoplastic

Pertaining to a NEOPLASM.

Of the 156 cases, 38 (24.35%) were diagnosed as inflammatory lesions and 114 (73.07%) as neoplastic lesions.
Pathologically, colloid carcinoma is defined as an infiltrating ductal epithelial neoplasm of pancreas characterized by the presence, in at least 50% of the neoplasm, of abundant extracellular stromal mucin pools and a scant amount of neoplastic cells floating in the center (5, 10).
These lesions frequently progress to invasive SCC (GROSS et al., 2005; TSUJITA & PLUMMER, 2010), suggesting solar radiation as the main factor predisposing to neoplastic invasion in these outbreaks.
The mucous-producing neoplastic cells formed acinar structures containing swollen cells with abundant clear cytoplasm and round central nuclei, or nuclei displaced to the periphery (signet-ring cells) (Fig 3D).
Among the neoplastic lesions, in the present study, follicular adenomas were diagnosed with 100% accuracy by FNAC.
Ovarian masses were broadly classified into non-neoplastic and neoplastic. Non-neoplastic masses included Follicular cyst, Corpus luteal cyst, Endometriotic cyst and inflammatory masses.
Non neoplastic lesions were common in the second decade and as age advances neoplastic lesions like Low grade appendiceal mucinous neoplasm and Mucinous adenocarcinoma of the appendix were encountered.
Histologically, neoplastic cells had markedly distended cytoplasm that was eosinophilic and often vacuolated, as is described in cases of other species (OMAR, 1969; JACOBSEN et al., 2010; KRAFSUR et al., 2014).
We had 67.53% of non-neoplastic lesions which outnumbered neoplastic lesions similar to a study by other researchers in India [3,5,8,9] as well as from other countries such as Pakistan, [7] Nepal, [10] and Nigeria.
Presumably, this fungal infection was secondary to the chronic neoplastic disease process because of immunosuppression.
Among these findings, absence of mass effect in adjacent vascular/biliary structures, characteristic location, ill-defined lesion borders rather than round or oval shape (which are characteristic for true neoplastic lesions), contrast enhancement pattern similar to background liver parenchyma should be counted (11).
