BACKGROUND/AIMS: A liver transplant is the preferred treatment for patients with end-stage liver disease, as it usually results in longterm survival. However, due to the use of chronic immunosuppressive therapy, which is necessary to prevent rejection, de novo cancer is a major risk after transplantation. The aim of this study was to assess the incidence of post-transplant malignancies in children after liver transplantations. MATERIALS AND METHODS: The study group consisted of 206 liver transplant recipients, with no history of cancer, including hepatocellular carcinoma, in two liver transplantation centers in Turkey between 1997 and 2015...

Primary lymphomas of the bone or skeletal muscle are rare. Three mechanisms of lymphomatous involvement of the muscle have been described, namely direct invasion from adjacent involved lymph nodes or bone, metastatic spread and, least commonly, primary muscle lymphoma. We herein present a rare case of primary mucle non-Hodgkin lymphoma with a description if the associated clinicopathological findings and a review of the relevant literature. A 41-year-old female patient was referred to our hospital with a painful mass in the right lower extremity...

Cutaneous diffuse large B-cell lymphoma accounts for ~6% of all cutaneous lymphomas. It is associated with poor prognosis, and solitary lesions are relatively rare. It often requires an aggressive approach with multi-agent chemotherapy and radiotherapy. It is important to recognize these cases in order to offer rapid and appropriate management.

Atypical lymphocytic infiltrates of the skin comprise a broad spectrum of entities ranging from benign infiltrates to those that are malignant. Many of these infiltrates are in fact reactive lymphomatoid ones related to drug therapy falling under the general category of drug associated pseudolymphoma. Within this nosologic umbrella are nodular and diffuse infiltrates resembling low grade T and B cell lymphoma consistent with lymphocytoma cutis, drug associated reversible T cell dyscrasias which draw a strong morphologic and phenotypic parallel with mycosis fungoides and the various pre-lymphomatous T cell dyscrasias, and angiocentric CD30 positive infiltrates mirroring lymphomatoid papulosis...

Patients with mycosis fungoides (MF), the most common subtype of primary cutaneous T-cell lymphoma, have an increased risk of developing secondary malignancies. We herein report two rare cases of MF concurring with diffuse large B cell lymphoma (B lymphoid lineage) and acute myeloid leukemia (myeloid lineage) in two otherwise healthy elderly patients. Potential etiologic factors, including the impact of the therapy-associated inflammatory response on the development of secondary tumors in patients with MF, are discussed...

BACKGROUND: While substantial dermoscopic analysis of melanocytic lesions has been performed, dermoscopic characterization of cutaneous lymphoid proliferations has been limited. Cutaneous lymphoma, particularly early mycosis fungoides (MF) and its variants, is often challenging to clinically and pathologically distinguish from inflammatory processes of the skin. This study aimed to survey the dermoscopic findings of cutaneous lymphomas and to discern whether any patterns might potentially serve as specific signatures...

Suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor (HDACI) approved by FDA for the treatment of cutaneous T cell lymphoma, is a promising anticancer drug for various cancers with a unique mode of action. However, it demonstrates limited clinical benefits in solid tumors as a single drug. In order to achieve enhanced and synergistic co-delivery of SAHA and Doxorubicin (DOX), a cleavable SAHA-based prodrug polymer (POEG-b-PSAHA), consisting of hydrophilic poly(oligo(ethylene glycol) methacrylate) (POEG) blocks and hydrophobic SAHA segments, has been developed...

The authors report a case of a 69-year-old woman with multiple sclerosis treated with fingolimod for duration of over one year who subsequently developed cutaneous large B cell lymphoma. There are few reported cases of lymphoma associated with fingolimod treatment for multiple sclerosis, but rates are higher than expected in the general population. The authors hope to promote awareness of the potential risk of this medication so that more diligent disease surveillance can be performed by both prescribing practitioners of fingolimod and their patients who receive it...

Cutaneous lymphomas are classified according to their cellular origin into T-cell lymphoma and B-cell lymphoma. The annual incidence rate is 0.3 per 100,000 population. We report a case of a 56-year-old male patient who presented with a two-month history of nodules of varying sizes, some ulcerated, on the face, abdomen, and upper limbs. Histopathological examination and immunohistochemical study confirmed the diagnosis of primary cutaneous centrofollicular lymphoma. Studies have shown an increased incidence of non-Hodgkin lymphomas in the last decade...

Coagulation factor VIII (FVIII), von Willebrand factor (VWF), and ADAMTS13 play an important role in regulation of normal hemostasis. However, little is known about their roles in patients with malignancy, particularly with cutaneous melanoma. Whole genome sequencing data are available for 25,719 cases in 126 cancer genomic studies for analysis. All sequencing data and corresponding pathology findings were obtained from The Cancer Genome Atlas. The cBioportal bioinformatics tools were used for the data analysis...
