(a.) Pertaining to pleomorphism; as, the pleomorphic character of bacteria.
Example Sentences:
(1) The mutant spores are pleomorphic and differ both in shape and size from the wild-type spores.
(2) The revised diagnosis was pleomorphic rhabdomyosarcoma for one case and pleomorphic leiomyosarcoma for the other cases.
(3) GABA-immunogold reaction has revealed the presence of this inhibitory transmitter in most axon terminals containing ovoid-pleomorphic vesicles within the molecular layer, including those resembling climbing fiber-terminals.
(4) Pleomorphic glioma cells but especially astrocytoma cells reacted positively also for the GFA protein.
(5) These findings suggest that the presence of features such as large prominent nucleoli, tumor growth in sheets, individual-cell necrosis, and nuclear pleomorphism may be used to predict recurrence of subtotally resected meningiomas that would not be classified as malignant by traditional criteria.
(6) Bouton-like terminals were found to be of two types according to their vesicle content, namely, boutons with ovoid, clear synaptic vesicles forming Gray type-1 synapses and boutons with pleomorphic clear synaptic vesicles forming Gray type-2 synapses.
(7) Malignant fibrous histiocytoma is a pleomorphic soft tissues sarcoma usually found in the extremity and in the retroperitoneum.
(8) Specifically discussed are mixed tumor, monomorphic adenoma, carcinoma ex-pleomorphic adenoma, clear-cell tumor, sebaceous lymphadenoma, and sebaceous carcinoma.
(9) Irradiation may have been responsible for inducing a true malignant mixed tumour as distinct from the more common malignancy which may arise in pleomorphic adenoma, this being a simple carcinoma.
(10) Electron microscopy of two cases of anaplastic giant cell tumor of the thyroid revealed that these neoplasms consisted of pleomorphic cells with large, bizarre-shaped nuclei and relatively little cytoplasm rich in rough endoplasmic reticulum.
(11) Malignant fibrous histiocytomas of the storiform pleomorphic type were found in the lower legs of two patients, 79 and 42 years of age.
(12) Thirty-two cases of soft tissue malignant fibrous histiocytoma (MFH), including 24 of common storiform-pleomorphic type, 7 of myxoid type, and 1 of inflammatory type, were analyzed in an ultrastructural quantitative study, the objective being to clarify the cellular composition and distribution of the tumor.
(13) All types of hyperplasia were frequently seen in areas adjacent to carcinomas, including ductal, pleomorphic, mucinous, adenosquamous, small and spindle cell and cystadenocarcinomas.
(14) Stereoscopic observations clearly showed that the bacteria were pleomorphic, rod-shaped, arranged in a row or at an angle, and frequently showed septal formation.
(15) The aortic tumour consisted of pleomorphic spindle-shaped and giant cells.
(16) Poorly-differentiated tissue produced a more haphazard out-growth of pleomorphic cells with few processes and flattened pseudopodia.
(17) We identified five histopathological categories in 66 patients: one with an excellent prognosis (large, cleaved cell, six of eight patients surviving for two years); two with an intermediate prognosis (large, noncleaved and mixed follicular-center cell, nine of 18 and eight of 17, respectively, surviving for two years); and two with a poor prognosis (blastic and pleomorphic pyroninophilic, one of 10 and two of 13, respectively, surviving for two years).
(18) Despite the pleomorphism and the variation of cell components, it is suggested that the stellate, intermediate and physaliferous cells, constitute the same cell at different stages of maturation.
(19) We present a case of pleomorphic adenoma of the soft palate parapharyngeal, which is removed using transoral approach with the addition of lateral cervicotomy to control of the great vessels.
(20) These tumors included seven meningiomas, one hemangiopericytoma, three meningeal sarcomas (1 pleomorphic-cell type and 2 myxofibrosarcomas), two fibrous histiocytomas, and four malignant melanomas.
Pleomorphism
Definition:
(n.) The property of crystallizing under two or more distinct fundamental forms, including dimorphism and trimorphism.
(n.) The theory that the various genera of bacteria are phases or variations of growth of a number of Protean species, each of which may exhibit, according to undetermined conditions, all or some of the forms characteristic of the different genera and species.
