Brian Z Rayala, Dean S Morrell
Cutaneous adverse drug reactions are among the most common noninfectious rashes of childhood. Cutaneous adverse drug reactions are classified as morbilliform, urticarial, bullous, pustular, or psoriasiform. Atopic dermatitis is one of the most common inflammatory cutaneous eruptions, and is characterized by pruritus and flexural distribution. Emollients and topical corticosteroids are first-line therapies. Topical calcineurin inhibitors are second-line, steroid-sparing drugs for certain conditions, such as face and eyelid eczema...

BACKGROUND: Erythroderma is a serious medical condition characterized by inflamed red skin involving over 90% of the body. It can be the common presentation of different diseases, therefore clinical diagnosis can be problematic. Controversial data are reported regarding the diagnostic value of histological examination in erythroderma subjects. METHODS: A retrospective study was performed, investigating histological skin specimens of patients with a clinical diagnosis of erythroderma admitted to the Department of Dermatology of State Pediatric Medical University, Saint Petersburg, from 2001 to 2014...

The immune checkpoint targeted agents, anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and anti-programed cell death 1 (PD-1) or anti-programmed death ligand 1 (PD-L1) inhibitors are frequently associated with cutaneous side effects that are often dose limiting and can lead to discontinuation of therapy. Ipilimumab, a CTLA-4 inhibitor, is most commonly associated with a morbilliform eruption on the trunk and extremities and pruritus. More severe cutaneous toxicities reported include toxic epidermal necrolysis and severe drug rash with eosinophila and systemic symptoms...

BACKGROUND: Immune checkpoint blockade therapy (ICBT) for the treatment of melanoma has led to an important improvement of overall survival in advanced stage patients. However, secondary cutaneous maculopapular eruptions (CMPEs) are frequent and remain poorly characterized. METHODS: We performed a retrospective analysis of melanoma patients from our institution who developed CMPEs during ICBT. Clinical information was retrieved, and histopathological and immunohistochemical characterization was performed by two pathologists...

INTRODUCTION: Fluoroquinolones are most widely used for empirical treatment of gastrointestinal disease due to emergence of drug resistant strains to other antimicrobials. They are also indulged in cutaneous adverse drug reactions with varying form of severity. CASE PRESENTATION: A 43 year old male patient developed fixed drug eruptions after administration of tablet norfloxacin and metronidazole for treatment of colicky abdominal pain with diarrhoea. Erythematous rashes involved whole body including buccal mucosa...

Linear IgA bullous dermatosis (LABD) is an autoimmune vesiculobullous disease, which is typically idiopathic but can also rarely be caused by medications or infections. Vancomycin is the most common drug associated with LABD. Lesions typically appear 24 hours to 15 days after the first dose of vancomycin. It is best characterized pathologically by subepidermal bulla (blister) formation with linear IgA deposition at the dermoepidermal junction. Here we report an 86-year-old male with a history of left knee osteoarthritis who underwent a left knee arthroplasty and subsequently developed a prosthetic joint infection...

BACKGROUND: Psoriasis is a chronic immune-mediated disease and treatment of psoriasis includes conventional immunosuppressive agents and biological agents. There are a few data on the relationship between psoriasis and melanocytic lesions. Either benign or malignant proliferations may be seen with immunosuppressive treatment. Eruptive nevi and malignant melanoma (MM) have been reported also associated with biological agents There is raising link biological treatment and malignancies. The objective of this paper is to examine the effects of biological agents versus conventional drugs on melanocytic nevi count and dermoscopical features...

Herpes zoster (HZ) is a painful, blistering skin eruption in a dermatomal distribution caused by reactivation of a latent varicella zoster virus in the dorsal root ganglia (DRG). Post-herpetic neuralgia (PHN) is the most common complication of acute herpes zoster (AHZ).Severe prodrome, greater acute pain and dermatomal injury, and the density of the eruption are the risk factors and predictors for developing PHN. PHN has a substantial effect on the quality of life; many patients develop severe physical, occupational, social, and psychosocial disabilities as a result of the unceasing pain...

REVIEW
H Y Lee, S A Walsh, D Creamer
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe adverse reactions to drugs which cause a life-threatening eruption of mucocutaneous blistering and epithelial sloughing. The two terms describe phenotypes occurring at either end of a severity spectrum: SJS is the less extensive form (<10% body surface area (BSA) detachment), while TEN is the more extensive (>30% BSA detachment). Cases in which there is 10-30% epidermal detachment are referred to as SJS-TEN overlap. This article is protected by copyright...

OBJECTIVE: Drug therapy is occasionally accompanied by an idiosyncratic severe toxicity, which occurs very rarely, but can lead to patient mortality. Methazolamide, an anti-glaucomatous agent, could cause severe skin eruptions called Stevens-Johnson syndrome/toxic epidermal necrolyis (SJS/TEN). Its precise etiology is still uncertain. In this study, the metabolism of methazolamide was investigated in immortalized human keratinocytes to reveal the possible mechanism which causes SJS/TEN...

Immunotherapy targeting the programmed cell death 1 (PD-1) receptor has demonstrated tremendous promise in the treatment of advanced solid tumors. Dermatologic toxicities, however, are an emerging consequence of this therapy and have been clearly associated with immune checkpoint blockade antibodies. Distinctive clinical and histologic subtypes of dermatologic toxicity secondary to immunotherapy are emerging and include rare autoimmune bullous reactions (eg, bullous pemphigoid) and lichenoid eruptions. We report three patients who developed lichenoid dermatitis while receiving anti-PD-1 antibody therapy...

Dear Editor, Pityriasis rosea is a common, acute, and self-limiting dermatosis, which is associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and/or HHV-7 (1). It predominantly affects individuals of both sexes in their second or third decade of life and is clinically characterized by the occurrence of an initial erythematosquamous plaque followed by the appearance of disseminated similar but smaller lesions one or two weeks later. Several patients develop systemic symptoms such as nausea, anorexia, malaise, headache, fever, arthralgia, and lymphadenopathy that may precede or accompany the eruption; the latter follows the cleavage lines of the trunk creating the configuration of a Christmas tree and spontaneously resolves within 4 to 8 weeks...

Three cases of pseudoherpetic transient acantholytic dermatosis (Grover disease) are presented, followed by a brief review of prior reports. All three patients were above the age of 60 and presented with a pruritic eruption composed of papules with or without vesicles distributed on the trunk. For all three patients, the clinical differential diagnosis included drug eruption but did not include Grover disease; in one patient, the clinical impression included herpesvirus infection. Similar histologic and immunohistochemical findings were demonstrated in all three cases...

Acute localized exanthematous pustulosis is a localized variant of acute generalized exanthematous pustulosis, which is characterized by the eruption of multiple scattered pustules following drug administration. A 72-year-old woman presented with multiple erythematous pustules on her face, which had appeared two days after using cefoperazone and sodium sulbactam. Histopathological findings showed subcorneal pustules and mixed inflammatory cell infiltration in the dermis. The pustules resolved within about two weeks after the patient discontinued the antibiotics...

Granuloma annulare (GA) is a benign, granulomatous cutaneous disease without clear etiology. Disseminated and drug induced granuloma annulare is a rare presentation. We present a 47-year-old woman with diffuse circular erythematous eruptions following treatment with levetiracetam. Her clinical and histopathological findings were compatible with the diagnosis of granuloma annulare. To the best of our knowledge, there is no previous report of this skin disease as a result of levetiracetam use. We report this case to highlight this antiepileptic drug as a possible etiologic agent in disseminated granuloma annulare...

Keratoacanthoma (KA) is a subtype of squamous cell carcinoma whose development has been linked to excessive sun exposure, immunosuppression, and trauma. Given the rapidly expanding therapeutic armamentarium for anti-aging modalities in dermatology, reports of KA secondary to invasive cosmetic procedures are on the rise. We present a case of eruptive KAs after full- eld ablative Erbium:YAG 2940 nm laser resurfacing of the face that resolved with minimal intervention. This case demonstrates the potential for a rare yet signi cant laser complication that may warrant discussion during the consenting process...

Some cutaneous inflammatory disorders are typified by a predominant or exclusive localization in the dermis. They can be further subdivided by the principal cell types into lymphocytic, neutrophilic, and eosinophilic infiltrates, and mixtures of them are also seen in a proportion of cases. This review considers such conditions. Included among the lymphoid lesions are viral exanthems, pigmented purpuras, gyrate erythemas, polymorphous light eruption, lupus tumidus, and cutaneous lymphoid hyperplasia. Neutrophilic infiltrates are represented by infections, Sweet syndrome, pyoderma gangrenosum, and hidradenitis suppurativa, as well as a group of so-called "autoinflammatory" dermatitides comprising polymorphonuclear leukocytes...
