Malignant disease conditions 

Multiple myeloma is a malignant plasma cell disorder characterized by clonal proliferation of plasma cells within the bone marrow, leading to the production of monoclonal immunoglobulin (M protein) or free light chains. The disease causes end-organ damage through bone destruction, bone marrow failure, renal impairment, hypercalcaemia, and immunodeficiency.

These are tumors arising from nasal cavity and the four paired paranasal sinuses (frontal, ethmoid, maxillary, and sphenoid).

Carcinoma of the prostate is the most common malignant tumour of the prostate gland and one of the leading cancers affecting men worldwide. Approximately 95% of prostate cancers are adenocarcinomas arising from the glandular epithelium of the prostate.

Aggressive T-cell lymphomas are a heterogeneous group of mature T-cell and natural killer (NK)-cell neoplasms characterized by rapid progression, aggressive clinical behavior, and generally poorer outcomes compared with most B-cell lymphomas. These malignancies are relatively rare and are often diagnosed at advanced stages with extranodal involvement.
