Aleukemic leukemia cutis is a rare condition in which malignant white cells invade the skin before they appear in the peripheral blood or bone marrow. It is often associated with a poor prognosis. The condition presents a diagnostic challenge as its manifestations are quite variable terms of lesion type. Read More

Introduction: Literature shows upcoming allergy to chlorhexidine due to the widespread use of the disinfectant within and outside surgical settings. Only a few case reports have been published regarding the use of topical chlorhexidine disinfectant outside surgery and only a minority of these within the pediatric population.

Case Report: We present a case-report of a teenager, treated for acute lymphoblastic leukemia who developed an anaphylactic shock after repeated chlorhexidine use for skin disinfection at the insertion of a central venous catheter during his chemotherapy treatment. Read More

The deubiquitination of histone H2A on lysine 119 by 2A-DUB/MYSM1, BAP1, USP16, and other enzymes is required for key cellular processes, including transcriptional activation, apoptosis, and cell cycle control, during normal hematopoiesis and tissue development, and in tumor cells. Based on our finding that MYSM1 colocalizes with γH2AX foci in human peripheral blood mononuclear cells, leukemia cells, and melanoma cells upon induction of DNA double-strand breaks with topoisomerase inhibitor etoposide, we applied a mass spectrometry-based proteomics approach to identify novel 2A-DUB/MYSM1 interaction partners in DNA-damage responses. Differential display of MYSM1 binding proteins significantly enriched after exposure of 293T cells to etoposide revealed an interacting network of proteins involved in DNA damage and replication, including factors associated with poor melanoma outcome.

Arsenic is a well-known environmental carcinogen and chronic exposure to arsenic through drinking water has been reported to cause skin, bladder and lung cancers, with arsenic metabolites being implicated in the pathogenesis. In contrast, arsenic trioxide (AsO) is an effective therapeutic agent for the treatment of acute promyelocytic leukemia, in which the binding of arsenite (iAs) to promyelocytic leukemia (PML) protein is the proposed initial step. These findings on the two-edged sword characteristics of arsenic suggest that after entry into cells, arsenic reaches the nucleus and triggers various nuclear events. Read More

Background: Extramedullary relapse is an important cause of treatment failure among patients with acute lymphoblastic leukemia (ALL). This type of relapse is commonly observed in the central nervous system, while it is rare in the testicles and skin.

We examined the risk of subsequent neoplasms (SNs) and late mortality in children and adolescents undergoing allogeneic hematopoietic cell transplantation (HCT) for nonmalignant diseases (NMDs). We included 6028 patients (median age, 6 years; interquartile range, 1-11; range, <1 to 20) from the Center for International Blood and Marrow Transplant Research (1995-2012) registry. Standardized mortality ratios (SMRs) in 2-year survivors and standardized incidence ratios (SIRs) were calculated to compare mortality and SN rates with expected rates in the general population.

Most patients have palpable lymphadenopathy, while 20-50% of the patients have hepatosplenomegaly. Cutaneous infiltrations in patients with CLL can be localized or generalized in the form of erythematous papules, plaques, nodules and, ulceration, which is uncommon. Read More

Introduction: After tyrosine kinase inhibitors (TKIs) targeting BCR-ABL1 were introduced for the treatment of chronic myeloid leukemia, clinical outcomes have improved dramatically. However, together with the increase in the survival rate, a more frequent occurrence of secondary malignancies has been observed as well. TKIs have been demonstrated to be a risk factor of malignancies such as non-Hodgkin lymphoma, prostate cancer, and skin cancer. Read More

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematologic malignancy arising from plasmacytoid dendritic cell precursors. The disease typically manifests in the skin, but it also evolves into a leukemic phase or can be complicated by other myeloid malignancies, especially myelomonocytic tumors. The association between these neoplasms is not fully elucidated. Read More

To evaluate cellular response to oncostatin M (OSM) in comparison to interleukin (IL)-31, we analyzed monocyte chemoattractant protein 1 (MCP-1) as a readout for OSM responses with and without IL-4, IL-13, anti-OSM receptor β monoclonal antibody KPL-716, and anti-IL-31 receptor α antibody in human epidermal keratinocytes and human dermal fibroblasts in vitro. In human epidermal keratinocytes, OSM significantly induced STAT3 or STAT1 phosphorylation and synergized with IL-13 or IL-4 in elevating MCP-1. In human dermal fibroblasts, OSM results were similar, and leukemia inhibitory factor or IL-31 minimally activated STAT3 but not MCP-1. Read More

B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) is one of the common lymphoproliferative disorders with an increased risk of developing subsequent neoplasms of epithelial and mesenchymal origin. The decreased immunity and B-cell dysfunction in CLL probably accounts for this emergence of secondary malignancy. Breast, brain, skin and prostate tumors have been reported as usual coincident malignancies of CLL, while in occasional cases CLL may occur with malignancies of other solid organs, such as skin, lung, heart, and prostate.

Transepidermal elimination of altered and perforating bundles of basophilic collagen from the epidermis is a characteristic histologic feature of acquired reactive perforating collagenosis. Along with its well-known association with systemic diseases such as diabetes mellitus, chronic renal failure, and dermatomyositis, there are reports of acquired reactive perforating collagenosis being associated with malignancies.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, aggressive malignancy derived from the plasmacytoid dendritic cell that commonly involves the skin. Cutaneous involvement is often the initial presentation, with deep purple or red-brown macules, plaques, or tumors. As such, dermatologists may be the first to see these patients and, in addition to oncologists, should be familiar with its presentation to facilitate early diagnosis, helping to distinguish it from acute myelogenous leukemia cutis.

The critical roles of keratinocytes and resident mast cells in skin allergy and inflammation have been highlighted in many studies. Cyclic adenosine monophosphate (cAMP), the intracellular second messenger, has also recently emerged as a target molecule in the immune reaction underlying inflammatory skin conditions. Here, we investigated whether undecane, a naturally occurring plant compound, has anti-allergic and anti-inflammatory activities on sensitized rat basophilic leukemia (RBL-2H3) mast cells and HaCaT keratinocytes and we further explored the potential involvement of the cAMP as a molecular target for undecane.

Purpose Of Review: Extramedullary disease (EMD) is a rare but recognized manifestation of multiple myeloma (MM), characterized by involvement of several organs including skin, liver, lymphatic system, pleura, and central nervous system. The incidence is about 3-5% in newly diagnosed MM patients, but has been reported in up to 20% patients in the relapsed MM setting.

Recent Findings: Presence of EMD has been associated with more aggressive phenotype of MM, elevated serum lactate dehydrogenase (LDH) enzyme, and high-risk cytogenetics [deletion 17p, translocation (4;14), translocation (14;16)]. Read More

Leukemia cutis (LC) is the cutaneous presentation of any type of leukemia and occurs in 10% to 15% of patients with AML, but cutaneous infiltration of AML rarely precedes the involvement of the bone marrow or peripheral blood and is called as "aleukemia cutis."
