Solitary bone plasmacytomas are part of a wide range of monoclonal neoplasms that share a common progenitor in the B lymphocyte lineage. In their particular case, a single bone lesion is found, most frequently on the axial skeleton, having evidence of no other osteolytic lesions or systemic involvement. Diagnosis can sometimes prove to be difficult as they are rare tumors, occurring in 3 to 5% ...

Haematological neoplasms comprise a collection of heterogeneous neoplastic conditions that arise from cells the bone marrow and lymphoid system. This study describes pattern distribution haematological at tertiary hospital inNorthernProvince,Sri Lanka. A descriptive retrospective audit was conducted ofall diagnosed by peripheral blood examination. total 435 were reported during 4-year period. A...

FBJ virus was injected i.p. into 145 neonatal NIH Swiss [N:NIH(s)] mice. Eighty mice developed a total of 110 neoplasms by 5 months of age. The mean latent period of the tumors was 71 days (26 to 145) postinjection. The frequency of occurrence of neoplasms at different sites was: diaphragm, 45%; ribs, 14%; vertebrae, 14%; femora, 9%; pelvic bones, 5%; tibiae, 4%; sternebrae, 3%; and inguinal ar...

BACKGROUND Secondary myeloid neoplasms comprise a group of diseases arising after chemotherapy, radiation, immunosuppressive therapy or from aplastic anemia. Few studies have addressed prognostic factors in these neoplasms. METHOD Forty-two patients diagnosed from 1987 to 2008 with secondary myeloid neoplasms were retrospectively evaluated concerning clinical, biochemical, peripheral blood, b...

| 1634 | haematologica | 2009; 94(12) The World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues includes within myeloid neoplasms the category “Myelodysplastic/myeloproliferative neoplasms”. According to Vardiman et al., these are “clonal myeloid neoplasms that at the time of initial presentation have some clinical, laboratory or morphologic findings tha...

The nasal cavity harbors a wide variety of benign and malignant neoplasms. Benign neoplasms include those arising in epitelial and soft tissues. Hemangioma is an infrequent neoplasm of the nasal cavity, mostly arising in the mucosa and rarely in the bone. We report a case of an intraosseous cavernous hemangioma arising from the nasal floor in a 51 years old woman.
