A case of Jarisch-Herxheimer reaction in candidiasis treated with systemic fluconazole.

Jarisch-Herxheimer reaction (JHR) is an acute and self-limited condition, which commonly occurs after treatment for spirochetal infections. Probably, it corresponds to a transient immunological reaction to endotoxin-like products released from the microorganism during the therapy. For this reason, JHR may be associated with many other infectious diseases besides syphilis. Here, we report a case of a patient affected by extended cutaneous candidiasis diagnosed by culture examination; a JHR occurred after an accidental overdose of oral fluconazole.

Complete resolution of cutaneous larva migrans with topical ivermectin: A case report.

Cutaneous larva migrans (CLM; also called creeping eruption) is a cutaneous ectoparasitosis commonly observed in tropical countries. It is characterized by an erythematous, pruritic, and raised lesion with linear or serpiginous distribution, typically localized at the lower extremities. Oral ivermectin represents the most recommended current treatment, with important adverse effects associated. We report the clinical case of a 52-year old with CLM, successfully treated with topical ivermectin.

Erythema multiforme: Differences between HSV-1 and HSV-2 and management of the disease-A case report and mini review.

Erythema multiforme (EM) is an immune-mediated reaction characterized by target lesions and with possible mucosal involvement. Its most frequent cause is HSV, with HSV-1 more common than -2. It is usually self-limited but it can show recurrences. We report a peculiar case of recurrent herpes-associated erythema multiforme (HAEM) in a 35-year-old man. The patient was affected by both herpes labialis and genitalis, but the typical target lesions were only associated with recurrent herpes labialis. Here, we hypothesize about the pathogenic differences between HSV-1 and HSV-2, and discuss the therapeutic management of HAEM.

Linear cutaneous hypopigmentation and atrophy associated with intralesional steroid injection: A rarely described adverse reaction.

Intralesional steroid injection is a common and highly effective treatment procedure, which can be successfully used for several dermatologic, rheumatologic, and orthopedic disorders. However, it may be associated with various local side effects, such as pain, granulomatous reaction, allergic reactions, hypo or hyperpigmentation and, uncommonly, skin atrophy. A peculiar and rare side effect of steroid injection is linear hypopigmentation and atrophy, which is probably an expression of lymphatic spread of corticosteroid crystals. Here, we report a case of linear hypopigmentation and atrophy in a 26-year-old male patient.

A "seasonal bromoderma" in a farmer.

Bromoderma is a rare skin disease caused by the ingestion, inhalation, or contact with products containing bromides. We report a case of bromoderma in a 36-year-old farmer, characterized by remission during the spring and exacerbation during the winter. The recognition of the use of products containing bromides during the winter helped us to understand the cause of the clinical condition.

The management of pseudomyogenic hemangioendothelioma of the foot: A case report and review of the literature.

Pseudomyogenic hemangioendothelioma (PMH) is a rare, mostly indolent, endothelial neoplasm of low-grade malignancy, often mimicking myoid and epithelioid tumors histologically. It is more frequent in young adult males and it usually presents with multiple cutaneous nodules, mostly localized at the extremities. It traverses several tissue planes simultaneously and can involve dermis, subcutis, skeletal muscle, and bone. Histologically, it is characterized by plump spindle cells with eosinophilic cytoplasm, often arranged in fascicles and epithelioid cells with "pseudomyogenic" morphology. Immunohistochemically, PMH is positive for Factor VIII, FLI-1, INI-1, vimentin, MDM2, CDK4, CD31, AE1/AE3, EMA, and P63. The efficacy of treatments is only partially known. Because of the frequent multifocal aspect of PMH, which contraindicates surgery, systemic treatments, such as gemcitabine, sirolimus, and everolimus are used. Based on our observation of multifocal PMH of the foot in a 17-year-old male patient, treated with gemcitabine with complete cutaneous response in a 2-year follow-up, we decided to discuss this rare tumor and underline its progression and therapeutic approaches. Thanks to a correct diagnosis, it is possible to avoid aggressive therapeutic approaches, which would be necessary for nonindolent diseases, such as sarcoma, which often needs amputation.

Pitted keratolysis, erythromycin, and hyperhidrosis.

Pitted keratolysis (PK) is a plantar skin disorder mainly caused by coryneform bacteria. A common treatment consists of the topical use of erythromycin. Hyperhidrosis is considered a predisposing factor for bacterial proliferation and, consequently, for the onset of PK. The aim of this study was to evaluate the relationship between PK erythromycin and hyperhidrosis. All patients with PK seen in Sant'Andrea Hospital, between January 2009 and December 2011, were collected. PK was clinically and microscopically diagnosed. All patients underwent only topical treatment with erythromycin 3% gel twice daily. At the beginning of the study and after 5 and 10 days of treatment, a clinical evaluation and a gravimetric measurement of plantar sweating were assessed. A total of 97 patients were diagnosed as PK and were included in the study. Gravimetric measurements showed that in 94 of 97 examined patients (96.90%) at the time of the diagnosis, there was a bilateral excessive sweating occurring specifically in the areas affected by PK. After 10 days of antibiotic therapy, hyperhidrosis regressed together with the clinical manifestations. According to these data, we hypothesize that hyperhidrosis is due to an eccrine sweat gland hyperfunction, probably secondary to bacterial infection.

Neurodystrophic Hand Dermatitis: Sannino Barduagni Syndrome.

Hand eczema is a chronic disease (1), commonly considered the expression of a contact allergic or irritative dermatitis. However, when the prick/patch tests and laboratory investigations are negative, important diagnostic challenges may arise. Peripheral nerve fibers are in fact capable of releasing neuromediators. Thus, an alteration of the central and/or peripheral nervous system can cause the exacerbation as well as the onset of a cutaneous disease (2). From September 1, 2013 to August 31, 2015, we observed 5 female patients between 20 and 40 years old, with particular hand dermatitis lesions on the volar area, unilateral on the right hand in 3 patients and bilateral in 2 patients. In one case, the dermopathy extended to all the fingers, up to the area of the metacarpophalangeal joints, thenar, and hypothenar eminences. The skin appeared dry (Figure 1), anhidrotic, inelastic, thinned, scaly, and slightly erythematous (Figure 2). In some cases, the fingertips appeared sclerotic, while in other cases the transversal fissures on the flexural joints caused painful and incomplete finger flexion. The dorsal surface was unaffected and the nails healthy. Symptoms were paresthesia and burning sensation. All of the patients were in good general health, with negative routine laboratory investigations, IgE serum levels and prick/patch tests. One patient had just given childbirth three months before the onset of the disease. The patients had been suffering of their hand dermatitis for a duration ranging from 2 months and 2 years and had been treated unsuccessfully with topical and systemic drugs, mainly corticosteroids. We performed a cervical spine X-ray in different projections. In all patients, we observed a degenerative disease of the cervical spine with a reduction of intersomatic discs, primarily C5-C6 (Figure 3). This led us to establish a diagnosis of neurodystrophic hand dermatitis (NHD). Patients started specific treatment programs for the spinal disorder, intake of a vitamin B complex and repairing/soothing skin creams, with a partial improvement. NHD is rarely described in the literature; in 1964 Sannino et al. reported 89 female patients with skin alterations similar to the ones observed in our case series as well as negative patch/prick tests and laboratory investigations, and the main finding was the presence of a cervical spine disease between C5-C7 (3). Recently, Azimi et al. performed a review of skin diseases at sites affected by neurological deficits. They started to collect data from 1966, but did not mention cases attributable to NHD, which is an underestimated and misdiagnosed disorder (2). Cervical spine disease is a predisposing factor for the development of NHD. Additionally, thermoreceptors may be mainly involved, as also reported in brachio-radial pruritus (4-5), explaining the presence of burning sensation. However, in our opinion, NHD should not be classified as a "neurogenic inflammation". This term describes the vasodilation and protein extravasation caused by inflammatory neuropeptides and adrenergic transmitters that influence the antigen presentation, mast-cell degranulation, and cytokine release (2). In fact, corticosteroids and other immunosuppressors are ineffective. Specific treatments for cervical spine disease remain the treatment of choice, as does constant use of repairing/soothing skin creams. Antidepressants, physiotherapy, postural exercises, neuromodulators, and vitamin B complex may be also helpful.

Systemic mastocytosis presenting with gastrointestinal, bone and skin involvement.

Ultrasonography (US) is often the first imaging study performed in patient with abdominal pain or vague symptoms related to the gastrointestinal tract. To this end, it has been demonstrated that transabdominal sonography achieves good to excellent results in potential bowel disorders; especially, if ultrasonography findings are framed in the context of clinical information. Systemic mastocytosis is not a common disease and it usually involves skin, gastrointestinal tract and bone. It results from a clonal neoplastic proliferation of abnormal mast cells and clinically it can ranges from 'asymptomatic' with normal life expectancy to 'highly aggressive'. Symptoms are caused by the release of mast cells mediators, such as histamine, and by the increase bulk of mast cells in the tissue. We present herein a case of systemic mastocytosis presenting with abdominal symptomatology due to thickened colonic involvement showed by US associated with bone and skin involvement.

A case report of pityriasis lichenoides in a patient with chronic hepatitis C.

The authors describe a case of chronic hepatitis C associated with pityriasis lichenoides. The association and evolution during antiviral treatment of these two diseases in this patient point to a possible pathogenetic link between chronic C virus infection and pityriasis lichenoides.
