Propylthiouracil (PTU) is a commonly used medication for the treatment of hyperthyroidism. PTU is known to cause different adverse reactions including autoimmune syndromes. PTU-induced autoimmune syndromes can be classified into drug-induced lupus or drug-induced vasculitis. Differential diagnoses could be very challenging. PTU-induced vasculitis is more common than PTU-induced lupus, and has a higher risk of morbidity and mortality. Usually it is limited to the skin in a form of cutaneous leukocytoclastic vasculitis, but may also affect organs including kidneys and lungs...

Cutaneous melanoma, which develops from the pigment producing cells called melanocytes, is the most deadly form of skin cancer. Unlike the majority of other cancers, the incidence rates of melanoma are still on the rise and the treatment options currently available are being hindered by resistance, limited response rates and adverse toxicity. We have previously shown that an FDA approved drug leflunomide, used for rheumatoid arthritis (RA), also holds potential therapeutic value in treating melanoma especially if used in combination with the mutant BRAF inhibitor, vemurafenib...

BACKGROUND: The prognosis of people with metastatic cutaneous melanoma, a skin cancer, is generally poor. Recently, new classes of drugs (e.g. immune checkpoint inhibitors and small-molecule targeted drugs) have significantly improved patient prognosis, which has drastically changed the landscape of melanoma therapeutic management. This is an update of a Cochrane Review published in 2000. OBJECTIVES: To assess the beneficial and harmful effects of systemic treatments for metastatic cutaneous melanoma...

BACKGROUND: Cytotoxic T lymphocyte-mediated (CTL-mediated) severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), are rare but life-threatening adverse reactions commonly induced by drugs. Although high levels of CTL-associated cytokines, chemokines, or cytotoxic proteins, including TNF-α and granulysin, were observed in SJS-TEN patients in recent studies, the optimal treatment for these diseases remains controversial...

Adverse cutaneous reactions to drugs are any undesirable change in the structure or function of the skin. These are among the adverse side effects to common drugs. The most commonly implicated drugs are antibiotics and anticonvulsants. Cutaneous clinical manifestations are diverse ranging from mild or moderate reactions, such as urticaria and maculopapular rash, to severe cutaneous adverse reactions (SCAR), which are known due to their high morbidity and mortality (among these: Stevens-Johnson syndrome, toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS)...

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...

INTRODUCTION: Skin toxicity in patients receiving novel therapeutic cancer agents has become a very important marker in determining drug activity, but it can also severely impact their quality of life. About half of the patients receiving this type of oncologic treatment will develop cutaneous reactions, that is why adequate understanding and management of these side effects is very important for drug adherence and patients' quality of life. MATERIALS AND METHODS: We conducted a prospective study of consecutive patients who received oncologic treatment in our institution and presented with dermatologic side effects...

Methotrexate is an antimetabolite analog to folic acid that competitively inhibits the enzyme dihydrofolate reductase and thymidylate synthetase, essential for the synthesis of DNA and RNA. It is widely used in dermatology and its adverse effects on the skin and mucous membranes are varied, including mild and severe reactions. The appearance of erosions and skin ulcers as a manifestation of methotrexate cytotoxicity are quite infrequent. These would represent an early cutaneous sign of pancytopenia due to marrow toxicity secondary to this drug...

BACKGROUND: Fixed drug eruption is a cutaneous reaction to a systemic agent that typically presents as an annular or oval erythematous patch or blister and subsequently resolves with postinflammatory hyperpigmentation at the site. Ginkgo biloba leaf extract and vinpocetine are nutritional supplements used to enhance memory in patients with dementia and age-related memory impairment conditions such as Alzheimer's disease. PURPOSE: To describe a fixed drug eruption in a man who repeatedly developed pruritus and macular erythema on his distal penile shaft after ingesting a natural product containing Ginkgo biloba and vinpocetine...

OBJECTIVE: Systemic sclerosis (SSc) is a connective tissue disorder of unknown etiology, with heterogeneous clinical manifestations and chronic and often progressive course. The diffuse cutaneous form of SSc (dcSSc) is characterized by thickening of the skin (scleroderma) and distinctive involvement of multiple internal organs. Patients with limited cutaneous SSc (lcSSc) generally have long-standing Raynaud's phenomenon before other manifestations of SSc appear. Over the last decade the Interest of adipose-derived cell therapy in regenerative medicine has increased continuously...

Electrochemotherapy (ECT), as one of the very few available treatments for cutaneous and subcutaneous tumors when surgery and radiotherapy are no longer available, requires applying a proper electric field to the tumor to realize electroporation-mediated cytotoxic drug delivery. It is impossible to exhaust all possible electrical parameters on patients to realize the optimal tradeoff between tumor suppression and adverse effects. To address this issue, this study provides a feasible solution by developing a four-leaf micro-electrode chip (F-MEC) in which the electric field was specially designed by linear distribution to cover all possible electric field strengths for ECT...

Pseudo-allergic reactions-adverse, non-immunologic, anaphylaxis-like sudden onset reactions mediated through an IgE-independent pathway-are activated by various basic compounds and occur at least as frequently as IgE-mediated reactions to drugs. A large family of G protein coupled receptors (Mas-related genes; Mrgprs) is closely related to pseudo-allergies. However, few therapies can directly target pseudo-allergies and related Mrgprs. Saikosaponin A (SSA) is effective in the treatment of passive cutaneous anaphylaxis (PCA), adjuvant arthritis, and delayed hypersensitiveness...

Historically, drugs available for treating atopic dermatitis (AD) have been limited to topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI), with systemic immunosuppressants and phototherapy reserved for severe AD. Despite their efficacy, with long term use, these agents have associated safety concerns and limitations. More targeted options with fewer systemic and cutaneous side effects are needed for treating atopic dermatitis. Phosphodiesterase 4 is involved in the regulation of proinflammatory cytokines via the degradation of cAMP...

Hydroxychloroquine (HCQ) is an effective treatment of lupus erythematosus. Although adverse effects, mainly gastrointestinal and cutaneous manifestations, are rare, they may result in the cessation of medication in some patients with severe reactions. Therefore, the evaluation of a patient's condition is important for a dermatologist to decide whether to cease or continue HCQ. We herein report a case of a 36-year-old Japanese woman with systemic lupus erythematosus and cutaneous eruptions caused by the p.o...

Mari Orime
Diagnosis of severe cutaneous adverse drug reactions should involve immunohistopathological examination, which gives insight into the pathomechanisms of these disorders. The characteristic histological findings of erythema multiforme (EM), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) provide conclusive evidence demonstrating that SJS/TEN can be distinguished from EM. Established SJS/TEN shows full-thickness, extensive keratinocyte necrosis that develops into subepidermal bullae. Drug-induced hypersensitivity syndrome (DIHS) and exanthema in drug reaction with eosinophilia and systemic symptoms (DRESS) each display a variety of histopathological findings, which may partly correlate with the clinical manifestations...

Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative option for many disease states. Despite significant improvements in strategies used to prevent and treat acute and chronic graft-versus-host disease (a/cGVHD), they continue to negatively affect outcomes of HSCT significantly. Standard, first-line treatment consists of corticosteroids; beyond this, there is little consistency in therapeutic regimens. Current options include the addition of various immunosuppressive agents, the use of which puts patients at even higher risks for infection and other morbidities...
