Cetuximab is a chimeric human-murine monoclonal antibody that binds competitively and with high affinity to the epidermal growth factor receptor (EGFR) and is used to treat advanced squamous cell carcinoma of the head and neck. After receiving a total of six doses of cetuximab, a 72-year-old male presented with pretibial edema, acne-like skin rash, and nephrotic syndrome. The renal biopsy findings revealed features of thrombotic microangiopathy (TMA), with the expansion of the subendothelial zone, reduplication of the glomerular basement, and swelling of the endothelial cells...

On November 13, 2015, FDA granted accelerated approval to osimertinib (TAGRISSO™; AstraZeneca), a breakthrough therapy-designated drug for the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M-positive non-small cell lung cancer (NSCLC), as detected by an FDA-approved test, with progression on or after EGFR tyrosine kinase inhibitor therapy. Approval was based on durable tumor response rates in two single-arm, multicenter trials: the dose extension cohort of a first-in-human trial (AURA extension; n=201) and a fixed-dose, activity-estimating trial (AURA2; n=210)...

Vesiculobullous eruptions in the elderly represent a diverse range of varying pathophysiologies and can present a significant clinical dilemma to the diagnostician. Diagnosis requires a careful review of clinical history, attention to detail on physical and histomorphological examination, and appropriate immunofluorescence testing. We describe the case of a 73-year-old female who presented to our hospital with a painful blistering skin rash developed over 2 days. Examination of the skin was remarkable for numerous flaccid hemorrhagic bullae on a normal-appearing nonerythematous skin involving both the upper and lower extremities...

BACKGROUND: Rash is a common complaint in the emergency department. Many causes of rash are benign; however, some patients may have a life-threatening diagnosis. OBJECTIVE: This review will present an algorithmic approach to rashes, focusing on life-threatening causes of rash in each category. DISCUSSION: Rash is common, with a wide range of etiologies. The differential is broad, consisting of many conditions that are self-resolving. However, several conditions associated with rash are life threatening...

The epidemics of Chikungunya virus (CHIKV) and Zika virus (ZIKV) infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others...

Psoriasis is a common chronic inflammatory skin disease. Recently, few data have been published on epidemiology, comorbidity, or therapy in children with psoriasis. Psoriasis affects up to 2% of children in Europe, even during the first months of life. The link between psoriasis and metabolic comorbidities has been highlighted, notably in relation to excessive weight and obesity. The clinical picture of psoriasis in childhood resembles adult disease, however, some clinical features are noteworthy: neonatal diaper rash is relatively specific, face involvement and guttate psoriasis are more common, plaques are often smaller, and scales are finer and softer than in adults...

BACKGROUND: Fixed drug eruption is a hypersensitive skin response to drugs, which can present itself in different ways. The skin lesions are usually solitary, but can also appear as a maculopapular rash, Stevens-Johnson syndrome or toxic epidermal necrolysis. While fixed drug eruptions can be caused by various drugs, paracetamol is responsible in 1.5% of cases. CASE DESCRIPTION: A 58-year-old man was seen in general practice with a five-year-old exanthema on his torso, arms and legs...

We report on the case of a 49-year-old man who presented with increasing dyspnea and a skin rash. The community-acquired pneumonia was initially treated with broad spectrum antibiotics. The patient's respiratory condition rapidly worsened and the clinical picture of Waterhouse-Friderichsen syndrome developed with disseminated intravasal coagulopathy and necrosis of the toes. An infection with Capnocytophaga canimorsus, which had been caused by an initially unmentioned dog bite was confirmed. In view of the fulminant course and the high risk of operative treatment of the ubiquitous necroses in all limbs, a joint decision for deescalation of therapy was made together with relatives...

The purpose of this case report and review of the literature is to provide an exploration of the clinical symptoms, diagnosis, prevention, and management of propylthiouracil (PTU)-associated vasculitis in the intensive care setting. A PubMed search of the available literature was conducted using the MeSH search terms "propylthiouracil" and "vasculitis." The literature search returned 121 articles. Twenty-five were excluded because they were not in English. Fifty-nine case reports or case studies describing PTU-associated vasculitis were included...

Icotinib is a new epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that developed and used in China; this work was to evaluate its efficacy and safety in treating non-small cell lung cancer (NSCLC). Clinical studies evaluating the efficacy and safety of icotinib in treating NSCLC were identified from the databases of Medline, Web of Science, Embase and Cochrance Library. Pooled efficacy and safety of icotinib were calculated through a series of predefined search strategies. A total of 15 studies with 2,304 patients were involved in this study...

Leflunomide is an immunomodulatory drug exhibiting anti-inflammatory, anti-proliferative and immunosuppressive effects. It has been widely used for treatment of active rheumatoid arthritis. Despite its good safety profile cutaneous side effects like alopecia, eczema, pruritis and dry skin have been reported with Leflunomide use. Skin ucleration, vasculitis, lichenoid drug rash and Subacute Cutaneous Lupus Erythematosus (SCLE) have been rarely reported with its use. A rare case of Leflunomide induced SCLE is being reported in a female patient with rheumatoid arthritis...

Drug hypersensitivity reactions may manifest with either organ-specific or systemic symptoms, but cutaneous eruptions are the most common manifestations. Different medications may cause identical skin symptoms, whereas hypersensitivity to a single drug may manifest with various patterns of symptoms depending on the pathomechanism of hypersensitivity. Drug reactions should be also taken into account in the differential diagnosis of numerous skin rashes. Analysis of morphology of drug-induced lesions, about potential immunologic or nonimmunological mechanisms, is important for the final diagnosis...

BACKGROUND: Afatinib has been available in Japan for the treatment of epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) since May 2014. We conducted an observational study in patients treated with afatinib in Nagano prefecture, focusing on response and associated toxicities. METHODS: We analyzed the clinical records of NSCLC patients treated with afatinib between May 2014 and February 2015. RESULTS: The records of a total of 73 patients (27 men, 46 women) with a median age of 69 years (range: 42-85 years) were analyzed...

An 88-year-old man was diagnosed with trigeminal neuralgia, and treatment of carbamazepine 200 mg/day was initiated. About 6 weeks later, the patient developed a skin rash accompanied by fever. He was admitted to hospital and diagnosed with drug-induced hypersensitivity syndrome (DIHS) caused by carbamazepine. Oral carbamazepine treatment was stopped, but blood tests showed acute liver and acute renal failure. Drug-induced lymphocyte stimulation test (DLST) for carbamazepine, human herpes virus-6 (HHV-6) IgG, and CMV-HRP were negative...
