While therapy with epidermal growth factor receptor inhibitors leads to meaningful clinical responses in several tumor types, it has also been linked with perplexing toxic effects. Skin effects of these agents such as generalized papulo-pustular rash, trichomegaly, fingertip fissures, xerosis, pruritus and paronichias are now well characterized. Though uncommon, nail atrophic changes have also been described in subjects treated with these classes of agents. We describe herein unusual longitudinal thumbnail fissures caused by erlotinib therapy for metastatic lung cancer...

We report a case of a 25-year-old Chinese man with an exceptionally prolonged history of pustular psoriasis derived from inverse psoriasis who was unsatisfied with conventional treatment and was successfully treated with a single dose of infliximab without noticeable adverse effects. No recurrence or flaring was observed after 3 months of follow-up. This case illustrates that infliximab may be an effective and safe therapeutic option for patients with refractory pustular psoriasis derived from inverse psoriasis...

Pyoderma gangrenosum (PG) is a rare ulcerative skin disease that usually starts as a pustular lesion and rapidly progresses to a painful ulcer with undermined violaceous borders. The occurrence of PG during pregnancy is uncommon. We describe a case of a pregnant patient with PG who was diagnosed as having ulcerative colitis after delivery. Obstetricians need to understand the pathogenesis of PG and its associated conditions because it is important to make a proper diagnosis and provide targeted therapy.

Important changes in the understanding and management of drug hypersensitivity reactions during the last years result from the increasing importance of biologics in medical practice, which differ in their spectrum of adverse drug reactions (ADRs) from the classical covalent drugs. With regard to covalent drugs, ampicillin and amoxicillin as well as clavulanic acid play an increasing role among ADRs to betalactam antibiotics. Fluoroquinolones are mainly the cause of anaphylactic and photosensitivity reactions...

Internalized stigma is the adoption of negative attitudes and stereotypes of the society regarding a person's illness. It causes decreased self-esteem and life-satisfaction, increased depression and suicidality, and difficulty in coping with the illness. The primary aim of this study was to investigate the internalized stigma state of psoriatic patients and to identify the factors influencing internalized stigma. The secondary aim was to identify the correlation of internalized stigma with quality of life and perceived health status...

Objective: Postsurgical pyoderma gangrenosum is a rare but potentially devastating condition for surgical patients. While pyoderma gangrenosum has 2 subtypes, typical and atypical, each can be further classified by its heralding features. These include ulcerative, pustular, bullous, and vegetative. The presentation can be a result of trauma or, as mentioned before, postsurgical. The plastic and reconstructive surgeon most likely will encounter postsurgical pyoderma gangrenosum in practice, as it has been reported in patient populations frequently seen in plastic surgery clinics...

The role of archaea in microbial mats is poorly understood. Delineating the spatial distribution of archaea with mat depth will enable resolution of putative niches in these systems. In the present study, high throughput amplicon sequencing was undertaken in conjunction with analysis of key biogeochemical properties of two mats (smooth and pustular) from Shark Bay, Australia. One-way analysis of similarity tests indicated the archaeal community structures of smooth and pustular mats were significantly different (global R = 1, p = 0...

Patients with 'deficiency of the interleukin-36 receptor antagonist' (DITRA), caused by mutation of the IL36RN gene, exhibit psoriatic phenotypes, typically generalised pustular psoriasis (GPP). We report a paediatric case with DITRA, whose cutaneous lesions varied from psoriasis vulgaris in infancy to annular pustular psoriasis with acute exacerbation to GPP at 13 years of age. Conventional systemic treatments for GPP, which include oral retinoids, cyclosporine and methotrexate, are controversial in paediatric cases, because of their adverse effects and uncertain long-time consequences...

BACKGROUND: The use of potassium iodide (KI) to treat palmoplantar pustulosis (PPP) and pustulotic arthro-osteitis (PAO) has not previously been reported. Here, we report the first successful treatment of PPP and PAO with KI. PATIENT AND METHODS: Among 25 patients with PPP, seven had an associated PAO. All patients were administered 900 mg KI three times per day for 3 months. Overall, 12 patients received this medical treatment for the first time or had >6 months interval since the last therapy for PPP...

This case report demonstrates the challenges of diagnosing and managing acute generalized exanthematous pustulosis (AGEP) presenting as septic shock. The disseminated, erythematous, pustular rash is a common feature. However, extensive organ involvement and life-threatening hypotension are unusual. The constellation of signs has not previously been documented following amoxicillin therapy. Toxic epidermal necrolysis (TEN) and toxic shock syndrome (TSS) were considered in addition to AGEP because of the systemic presentation...

REVIEW
Stuart A Hill, Thao L Masters, Jenny Wachter
Etiology, transmission and protection: Neisseria gonorrhoeae (the gonococcus) is the etiological agent for the strictly human sexually transmitted disease gonorrhea. Infections lead to limited immunity, therefore individuals can become repeatedly infected. Pathology/symptomatology: Gonorrhea is generally a non-complicated mucosal infection with a pustular discharge. More severe sequellae include salpingitis and pelvic inflammatory disease which may lead to sterility and/or ectopic pregnancy. Occasionally, the organism can disseminate as a bloodstream infection...

Pulmonary nocardiosis is a severe and uncommon opportunistic infection caused by Nocardia species. We present a patient with cryptogenic organizing pneumonia who was receiving long-term immunosuppressive therapy, whose treatment course was complicated by cutaneous and pulmonary nocardiosis. Tissue cultures confirmed Nocardia brasiliensis. Nocardiosis should be a diagnostic consideration for patients treated with long-term immunosuppression who have worsening pulmonary symptoms and relapsing pustular skin lesions...

BACKGROUND: Pseudomonas oryzihabitans is a Pseudomonas bacterial organism rarely implicated in human infections. The bacterium has been isolated in a few reported cases of neurosurgical infections and patients with end-stage cirrhosis, sickle cell disease, and community-acquired urinary tract infections. Limited information exists in developing countries, however, because of the lack of advanced microbiological tools for identification and characterization of this bacterium. This case report describes the isolation of a rare Pseudomonas bacterium in a patient presenting with sepsis and skin infection...

BACKGROUND: Palmoplantar psoriasis has significant physical and emotional impact on patients and can be difficult to treat. OBJECTIVE: To evaluate the efficacy of ixekizumab in the treatment of patients with moderate-to-severe non-pustular palmoplantar involvement and moderate-to-severe plaque psoriasis. METHODS: In three phase 3, double-blind, placebo-controlled trials, patients with moderate-to-severe non-pustular plaque psoriasis (UNCOVER-1 (N=1296), UNCOVER-2 (N=1224), UNCOVER-3 (N=1346)) were randomised to subcutaneous 80 mg ixekizumab every 2 or 4 weeks (Q2W, Q4W), after a 160 mg starting dose, or placebo through week 12...

Erythrodermic psoriasis (EP) and generalized pustular psoriasis (GPP) are the most severe forms of psoriasis, resulting in significant morbidity and even mortality (1) . There are few evidence-based data on their treatment (2,3) . Secukinumab, a fully human anti-IL-17A monoclonal antibody, demonstrated strong efficacy in treating moderate to severe plaque-type psoriasis (4,5) . This article is protected by copyright.

Eosinophilic pustular folliculitis (EPF) is a rare cutaneous disorder that typically occurs in three clinical contexts: men, individuals who are immunosuppressed or have human immunodeficiency virus, and infants. A fourth subtype occurring 2 to 3 months after hematopoietic stem cell transplantation (HSCT) has recently been described in several adults. We report two cases of EPF arising in children after HSCT. It is important to recognize this form of EPF after HSCT and differentiate it from graft-versus-host disease since it responds readily to topical steroids and appears to have an excellent prognosis...

Pruritic folliculitis of pregnancy is a rare disease of unknown etiology. It occcurs primarily during pregnancy, usually with spontaneous resolution postpartum. It is characterized by a benign dermatosis, with papular and pustular follicular lesions that first appear on the torso and occasionally spread throughout the body. We report the case of a patient in the 27th week of pregnancy, with a two-month evolution of pruritic and papular erythematous lesions on her lower back. Differential diagnosis includes other pregnancy-specific dermatoses: gestational pemphigoid, pruritic urticarial papules and plaques of pregnancy (PUPPP), prurigo of pregnancy, and (PUPPP) and prurigo of pregancy...

In 2012, gain-of-function mutations in CARD14, which encodes caspase recruitment domain family member 14, were identified as the cause of familial psoriasis vulgaris (PV) and familial pityriasis rubra pilaris (PRP).(1,2) We and another group reported that CARD14 variants are associated with generalized pustular psoriasis (GPP) and palmoplantar pustular psoriasis (PPP).(3-5) The other reports mentioned that CARD14 mutations in individuals with GPP and erythrodermic PRP. (4,6) Very recently, we described PRP type V as an autoinflammatory disease caused by CARD14 mutations...
