Extramedullary plasmacytoma (EMP) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. Multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.We describe multiple primary EMP in a 37 year old man, without involvement of bone or bone marrow. EMP usually has a ...

PURPOSE Natural killer (NK) cell neoplasm is a rare disease that follows an acute course and has a poor prognosis. It usually emerges from the nose and appears in the ocular tissue as a metastasis. Herein, we describe a case of NK-cell neoplasm in which the eye was considered to be the primary organ. CASE A 50-year-old female displayed bilateral anterior chamber cells, vitreous opacity, bullo...

BACKGROUND AND AIM This study aimed at determining whether there is a risk regarding the development of second primary malignancies after patient exposure to the low and medium radioiodine activity used during the treatment of differentiated thyroid cancers (DTC). METHODS Second primary malignancies that occurred after DTC were detected in 1,990 patients treated between 1970 and 2003. The mea...

AIM OF THE STUDY To find differences between a group of patients with intraocular melanoma and another primary cancer and a group of patients with no identifiable second primary cancer. MATERIAL AND METHODS The analysis involved 240 participants, selected from patients who were treated for uveal melanoma at the Department of Ophthalmology and Ocular Oncology of the Jagiellonian University Med...

Blastic plasmacytoid dendritic cell neoplasm is an aggressive hematologic malignancy with a poor prognosis. No consensus regarding optimal treatment modalities is currently available. Targeting the nuclear factor-kappa B pathway is considered a promising approach since blastic plasmacytoid dendritic cell neoplasm has been reported to exhibit constitutive activation of this pathway. Moreover, nu...

It has been designated histologically as grade I neoplasm according to the 2007WHO classification (1). Despite this benign character dissemination and metastasis along the cerebrospinal axis and metastasis to distant s...

Papillary adenocarcinoma of the lungs is the most common primary lung adenocarcinoma, with the feature of papillary-like structure formation by cells. A dog was presented with the primary complaint of vomiting, hyporexia and increased respiratory effort. Thoracic radiography revealed increased soft tissue radiopacity of the right cranial lung lobe suggestive of possible consolidation or collaps...

We investigated 15,542 patients with suspected BCR-ABL1- negative myeloproliferative or myelodysplastic/myeloproliferative neoplasm (including 359 chronic myelomonocytic leukemia) by a molecular marker set. JAK2V617F was detected in the suspected categories as follows: polycythemia vera 88.3%, primary myelofibrosis 53.8%, essential thrombocythemia 50.2%, and not further classifiable myeloprolif...
