Sara Berg, Jennifer Villasenor-Park, Paul Haun, Ellen J Kim
PURPOSE OF REVIEW: Diagnosis and management of mycosis fungoides and Sézary syndrome (MF/SS) require accurate clinicopathological correlation and a multidisciplinary approach. We reviewed major advances in the field regarding diagnostic and prognostic tools as well as skin-directed therapies (SDTs) and systemic agents for MF/SS published in the past 2 years. RECENT FINDINGS: Improved technology (T-cell receptor high-throughput sequencing) and increased multicenter collaboration (Cutaneous Lymphoma International Consortium) have led to diagnostic/prognostic advances...

Lymphomatoid papulosis (LyP) is a benign papulonodular skin eruption with histologic features of malignant lymphoma. A new variant of LyP which was termed "type E" was recently described with similar clinical and histological features to angiocentric and angiodestructive T-cell lymphoma. LyP type E is characterized with recurrent papulonodular lesions which rapidly turn into hemorrhagic necrotic ulcers and spontaneous regression by leaving a scar. None of the available treatment modalities affects the natural course of LyP...

In 2015 a IARC Working Group upgraded the classification of PCBs to Group 1 "Carcinogenic to humans", also on the basis of evidence from epidemiological studies showing an excess risk for melanoma. Increased risks for non-Hodgkin lymphoma (NHL) and breast cancer were also reported though the evidence was limited. However, some recent reviews of studies on PCB exposure and risk of cancer provided discrepant findings. Therefore, we re-evaluated the association between exposure to PCBs and risk of melanoma and NHL by a systematic review and meta-analysis...

Hemangioma is one of the most common types of infantile vascular benign tumor. The aim of the present study was to investigate the role of B-cell lymphoma 2 (Bcl-2) and tumor protein p53 (p53) in the proliferation and apoptosis of hemangioma cells. A total of 38 paraffin-embedded hemangioma specimens (16 males and 22 females) and another 5 paraffin-embedded healthy surrounding tissue samples, collected between January 2007 and December 2010, were obtained from the Department of Pathology at Renmin Hospital of Wuhan University (Wuhan, China)...

Aquaporin-3 (AQP3), a water and glycerol channel, plays an important role in epidermal function, with studies demonstrating its involvement in keratinocyte proliferation, differentiation and migration and epidermal wound healing and barrier repair. Increasing speculation about the use of histone deacetylase (HDAC) inhibitors to treat skin diseases led us to investigate HDAC's role in the regulation of AQP3. The broad-spectrum HDAC inhibitor, suberolyanilide hydroxamic acid (SAHA) induced AQP3 mRNA and protein expression in a dose- and time-dependent manner in normal keratinocytes...

Lymphocytic infiltrations located in the extracellular matrix often accompany canine skin cancer. They can be characterised as an inflammatory infiltration and/or a second tumour - lymphoma. The aim of this study was an immunohistochemical analysis of a lymphocytic infiltration which accompanies spontaneous skin cancer. Twenty basal cell carcinoma, 20 non-keratinizing squamous cell carcinoma, 20 keratinizing squamous cell carcinoma and 8 sebaceous gland carcinoma samples which were accompanied by a lymphocytic infiltration and/or secondary lymphatic follicles were verified histopathologically...

BACKGROUND: Malignancies and lymphoma are common complications after kidney transplantation. However, no link has been made between the incidence of malignancies and HCV infection in this setting. This case-controlled study compared the incidence of malignancies, including lymphoma, between kidney transplant (KT) patients with or without HCV replication. PATIENTS AND METHODS: A total of 99 HCV-positive RNA-positive KT patients were matched with 198 (1:2) anti-HCV-negative patients according to age, gender, and date of transplantation, and were followed for 145...

It is unclear whether AL amyloidoma of the skin/subcutis represents a distinct entity, an indolent precursor of systemic amyloidosis, or a manifestation of cutaneous marginal zone lymphoma (cMZL). We collected 10 cases of cutaneous AL amyloidoma in order to better characterize the clinicopathologic features of this elusive entity (M:F=4:6; median age: 62.5 y, range: 31 to 82 y). Nine patients had a solitary nodule or plaque on the lower extremity (n=7), upper extremity (n=1), or chin (n=1). One patient had an AL amyloidoma on the right thigh and a second lesion on the right arm showing histopathologic features of cMZL without amyloid deposits...

First described in 1959, intravascular lymphoma (IVL) remains one of the most clinically challenging diagnoses due to its diverse and non-specific clinical manifestations and evasiveness in detection by standard investigations. Indeed, IVL deserves the title of 'medicine's greatest imitator'. We highlight a case of IVL where the diagnosis came too late in the clinical course, detected by random skin biopsy. Clinicians should strongly consider this diagnosis in presentations with persistent symptomatology despite appropriate interventions...

Previously, we have shown that extracellular basic pH plays a significant role in both the direct and indirect regulation of cellular processes in a wound; this in turn affects the wound-healing process. Several studies have demonstrated the importance of apoptosis modulation in the wound-healing process, especially in removing inflammatory cells and in inhibiting scar formation. However, the effects of extracellular basic pH on wound healing-related skin damage are yet to be examined. Therefore, we investigated the induction of accelerated apoptosis by extracellular basic pH in skin...

BACKGROUND: Previous reports of geographic clustering of cutaneous T-cell lymphoma (CTCL) in Texas, Pittsburgh, and Sweden as well as the occurrence of CTCL in married couples and family members raise a possibility of the existence of an external and potentially preventable trigger(s) for this rare skin cancer. METHODS: The authors studied CTCL incidence and mortality in Canada using 3 distinct population-based cancer databases. Data on patients' sex, age at the time of diagnosis, subtype of CTCL malignancy, reporting province, city, and postal code were analyzed...

RATIONALE: Chronic active Epstein-Barr virus infection (CAEBV) associated with hemophagocytic syndrome (HPS) and extra-nodal natural killer (NK)/T-cell lymphoma (ENKL) is a rare life-threatening disorder. This disease is easily misdiagnosed because of its varied presentations. PATIENT CONCERNS: An 18-year-old girl was admitted to our hospital with a history of edema in the lower limbs and intermittent fever lasting for more than 1 month. At admission, she had severe liver injury of unknown etiology...

Cancer is the leading cause of death in economically developed countries and the second leading cause of death in developing countries. The relationship between genetic polymorphisms and the risk of cancers has been widely researched. Excision repair cross-complementing group 2 (ERCC2) gene plays important roles in the nucleotide excision repair pathway. There is contrasting evidence on the association between the ERCC2 Asp312Asn polymorphism and the risk of cancer. We conducted a comprehensive meta-analysis in order to assess the correlation between these factors...

Breast metastases from extramammary cancers are rare and usually related to poor prognosis. The extramammary tumors most frequently exhibiting breast metastases are melanoma, lymphomas, ovarian cancer, lung, neuroendocrine tumors, and sarcomas. Due to the lack of reliable and specific clinical or radiological signs for the diagnosis of breast metastases, a combination of techniques is needed to differentiate these lesions from primary breast carcinoma or even benign breast lesions. Multiple imaging methods may be used to evaluate these patients, including mammography, ultrasound, magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET/CT)...

Adult T-cell leukemia-lymphoma (ATL) caused by human T-lymphotropic virus type 1 (HTLV-1) is generally associated with poor prognosis. The anti-CCR4 antibody mogamulizumab is one of the options for refractory or relapsed ATL. Mogamulizumab is intravenously administered as a single agent at a dose of 1.0 mg/kg once a week for 8 weeks. The overall response rate is reported to be 50%. Reported common adverse events after administration of mogamulizumab are leukocytopenia, infusion reaction, and skin rash. Although rare, mogamulizumab-associated cardiomyopathy has also been reported...

Natural killer/T-cell lymphoma is a rare, Epstein-Barr virus-associated type of cytotoxic lymphoma thatpresents mainly in the nasal cavity and its vicinity. Very few cases of primary cutaneous extranodal natural killer/T-cell lymphoma have been reported till date. All the previously reported cases of primary cutaneous extranodalnatural killer/T-cell lymphoma presented as lesions resembling cellulitis, subcutaneous nodules or ulcers. We report a rare case which presented as erythematous and purpuric round patches on the arms and was finally diagnosed as primary cutaneous extranodalnatural killer/T-cell lymphoma, following a skin biopsy...

Waldenstrom's macroglobulinamia (WM) is a rare malignant lymphoproliferative disorder, characterized by monoclonal IgM paraproteinemia and neoplastic proliferation of malignant lymphoplasmacytoid cells in the bone marrow. Traditionally, WM has been treated with modalities similar to those used in the management of other indolent lymphomas. Just recently, based on impressive clinical trial results in heavily pretreated WM patients, a new Bruton Tyrosine Kinase-inhibitor, Ibrutinib, has been approved for the treatment of this disorder...

Cutaneous T cell lymphoma is a heterogeneous group of lymphoproliferative disorders with different clinical behavior and prognosis in which malignant T cells accumulate in the skin. In the relapsed/refractory stage, treatment strategy varies depending on clinical perspective. We retrospectively evaluated advanced stage relapse or refractory mycosis fungoides and Sezary syndrome patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at our hospital. The overall response rate was 25%, while the disease progressed and relapsed after transplant in 38% of patients...

BACKGROUND Intravascular lymphoma (IVL) is a rare lymphoproliferative disorder characterized by the proliferation of large B lymphoma cells within the lumen of small-caliber blood vessels. Clinical features are nonspecific, presenting as a systemic disease with fever and may be life-threatening. Antemortem diagnosis is difficult but may be made with biopsies of affected tissues or with random skin biopsies.

Total-skin electron beam therapy (TSEBT) is one of most effective treatments that has been used for cutaneous T-cell lymphoma. Low-dose TSEBT regimens (10-12 Gy) appear to be an effective alternative to conventional-dose TSEBT (30-36 Gy), yielding short-term remission of cutaneous manifestations with minimal toxicity. TSEBT can be administered to patients any time after a diagnosis of mycosis fungoides (MF). Patients requiring rapid relief from cutaneous lesions or symptoms may particularly benefit from TSEBT as an initial therapy...
