BACKGROUND Radiofrequency thermal ablation (RFA) has been demonstrated to be useful for the treatment of liver neoplasms. The study aimed to evaluate the feasibility and safety of the combination of transarterial chemoembolization (TACE) and RFA, performed simultaneously to treat primary and secondary liver neoplasms. PATIENTS AND METHODS From July 2006 to October 2007, 34 patients (21 with H...

Mastocytosis is a heterogeneous group of rare diseases related to the clonal, neoplastic proliferation morphologically and immunophenotypically abnormal mast cells, that accumulate in one or more organ systems. Their pathophysiology dominated by activating mutations C-Kit (Stem Cell Factor receptor). Several pathological forms have been described ranging from isolated cutaneous mastocytosis aff...

Peripheral T-cell lymphomas (PTCLs) are rare neoplasms that recently have been the subject of much research into their complex pathophysiology. PTCLs a heterogeneous group tumors consisting nodal and extranodal leukemic cutaneous neoplasms. associated with biology arduous pathology which is currently being studied. According to this research, pathophysiology can be divided intrinsic extrinsic m...

background: the presence of noncutaneous neoplasms does not seem to increase the risk of cutaneous malignant melanoma; however, it seems to be associated with the development of other hematological, brain, breast, uterine, and prostatic neoplasms. an ecological transversal study was conducted to study the geographic association between cutaneous malignant melanoma and 24 localizations of cancer...

Objective: To study the pattern and distribution of hematological cancers in Hadhramout sector-Yemen compare with findings elsewhere country worldwide. Methods: Descriptive patients Hematological malignancies between January 2011 December 2015 recorded National Oncology center- Hadhramout. Cases were sub-grouped according to their lineage into lymphoid types which include Non-Hodgkin’s Hodgkin’...

background: mature t/ nk-cell neoplasms are a rare group of disorders and their presentation as leukemia is even rarer. most of the previous studies have focused on mature b-cell lineage leukemias and there is a paucity of data on mature t/nk-cell lineage leukemias. we, therefore, planned this study to analyze their spectrum, frequency, morphology and immunophenotypic features. methods: all cas...

Multiple primary malignant neoplasms (MPMNs) is a complex process in which the development of 2 or more simultaneously after certain interval observed. MPMNs develop independently from each other within one organs. Many etiopathogenetic factors can cause MPMNs. Numerous studies have been conducted to study effect T-cell immunity on this pathology. Today, there steady upward trend prevalence mpm...
