INTRODUCTION: The cutaneous abscess commonly occurs in the medical practice, its management being well known. However, atypical cases - multiple occurrence, recurrence and/or resistance to classical treatment can be very challenging for the physician. These cases can be addressed for consultation in several medical specialties depending the age of the patient and the site of the lesions. The systematization of the diagnostic approach would have a great impact for the clinical practice...

Cutaneous mucormycosis is a rare but often fatal invasive fungal infection that occurs most commonly in patients with diabetes, malignancy, and other immunocompromising conditions. We report an extremely preterm (<28 weeks) baby boy who developed polymicrobial sepsis and primary cutaneous mucormycosis within his first 10 days of life. He was successfully treated with medical management alone since he was not a candidate for surgery. Successful treatment of cutaneous mucormycosis without surgical debridement has been reported on only two other occasions...

BACKGROUND: Molluscum contagiosum is a common skin infection that is caused by a pox virus and occurs mainly in children. The infection usually resolves within months in people without immune deficiency, but treatment may be preferred for social and cosmetic reasons or to avoid spreading the infection. A clear evidence base supporting the various treatments is lacking.This is an update of a Cochrane Review first published in 2006, and updated previously in 2009. OBJECTIVES: To assess the effects of specific treatments and management strategies, including waiting for natural resolution, for cutaneous, non-genital molluscum contagiosum in people without immune deficiency...

WHIM syndrome is a condition in which affected persons have chronic peripheral neutropenia, lymphopenia, abnormal susceptibility to human papilloma virus infection, and myelokathexis. Myelokathexis refers to the retention of mature neutrophils in the bone marrow (BM), which accounts for degenerative changes and hypersegmentation. Most patients present heterozygous autosomal dominant mutations of the gene encoding CXCR4. Consequently, aberrant CXCL12/CXCR4 signaling impairs the receptor downregulation causing hyperactivation (gain-of-function) that affects BM homing for myelopoiesis and lymphopoiesis and the release of neutrophils in the bloodstream...

Leishmaniasis is a disease found throughout the (sub)tropical parts of the world caused by protozoan parasites of the Leishmania genus. Despite the numerous problems associated with existing treatments, pharmaceutical companies continue to neglect the development of better ones. The high toxicity of current drugs combined with emerging resistance makes the discovery of new therapeutic alternatives urgent. Here we report the evaluation of a binuclear cyclopalladated complex containing Pd(II) and N,N' -dimethylbenzylamine (Hdmba) against Leishmania amazonensis...

Similar to other intracellular pathogens, Leishmania parasites are known to evade the antimicrobial effector functions of host immune cells. To date, however, only few virulence factors have been described for Leishmania (L.) major, one of the causative agents of cutaneous leishmaniasis. Here, we characterized the expression and function of a L. major phosphatase which we termed LmPRL-1. This enzyme shows a strong structural similarity to the human phosphatases of regenerating liver (PRL-1, -2, and -3) that are regulating the proliferation, differentiation and motility of cells...

Mycobacterium abscessus infection tends to occur in patients with an advanced immunocompromised status. We encountered a case of intractable cutaneous M. abscessus infection that developed in a patient with systemic lupus erythematosus (SLE) during maintenance therapy. A 28-year-old woman developed a fever and redness of the skin on her buttocks. General antibacterial therapy was ineffective, and acid-fast bacteria were detected in the biopsy that was conducted to differentiate the dermal symptoms of SLE. The clinical findings eventually improved; however, the symptoms recurred multiple times during treatment...

Squamous cell carcinoma (SCC) is a common malignancy affecting humans and other animals. Papillomaviruses (PVs) are frequently reported as causal agents of cutaneous benign and malignant epithelial lesions in different animal species, but only few studies have investigated their role in ovine SCC. In this study, we explore the possible involvement of the Ovine aries PVs (OaPV1, OaPV2, OaPV3) in cutaneous SCC using an integrated histological and molecular approach. Forty cutaneous SCCs from different anatomical locations of Sardinian sheep and 40 matched non-SCC samples were evaluated histologically and by polymerase chain reaction (PCR) to assess the presence of ovine PVs...
