Cutaneous larva migrans with folliculitis: a new clinical presentation of this infestation.

Two patients (a 35-year-old woman and a 33-year-old man, just returned from trips to Jamaica and Barbados, respectively) presented with cutaneous larva migrans with folliculitis, a rare and atypical clinical presentation of this infestation. Histopathological examination revealed a follicular and perifollicular infiltrate prevalently consisting of lymphocytes and neutrophils, with numerous eosinophils. Both patients were successfully treated with oral albendazole.

Evaluation of efficacy of a skin lipid mixture in patients with irritant contact dermatitis, allergic contact dermatitis or atopic dermatitis: a multicenter study.

Disturbances of skin barrier function occur in several skin diseases, e.g., atopic dermatitis (AD), irritant/allergic contact dermatitis (ICD, ACD). Skin barrier damage triggers the production of cytokines that stimulate lipogenesis which may also cause inflammatory processes. The aim of this study was to evaluate the efficacy of a topical skin lipid mixture in the treatment of ICD, ACD and AD. 580 consecutive patients suffering from ICD, ACD or AD were treated with a skin lipid mixture containing ceramide-3 and patented nanoparticles. Patients received the lipid mixture alone or in combination with topical corticosteroids until clearance or for 8 weeks. Both treatment groups statistically improved all parameters considered at week 4 and 8 as compared to baseline. Between the 2 treatment groups, there was a statistically significant difference in favour of combined therapy for (ICD, ACD, AD, respectively): erythema, pruritus and overall disease severity; erythema and pruritus; erythema, pruritus, fissuring and overall disease severity. No statistically significant difference was found for (ICD, ACD, AD, respectively): dryness, scaling and fissuring; scaling, fissuring and overall disease severity; dryness and scaling. Between the 2 ACD treatment groups, there was a statistically significant difference in favour of the skin lipid mixture for dryness. In conclusion, the study shows that balanced lipid mixtures are effective in improving barrier properties and the clinical condition of the skin in contact dermatitis.

Case report. Erythrasmoid pityriasis versicolor.

A 50-year-old Caucasian man with pityriasis versicolor that was localized almost exclusively in the inguinal folds and was characterized by lesions clinically superimposable on those of erythrasma is described. Due to these clinical characteristics, it is proposed that this variety of pityriasis versicolor is defined as 'erythrasmoid'.

c-Myc expression in human anagen hair follicles.

The hair follicle represents a very attractive organ system for studying the precise balance between cell proliferation, growth, differentiation, and death of cells, because it periodically and regularly regenerates, retaining its morphogenetic signals throughout its life. One of the most intriguing oncogenes which is able to induce both cell growth and apoptosis, depending upon the environmental conditions, is c-myc. The aim of the present study was to investigate its presence and localization in human hair follicles by immunohistochemistry and immunofluorescence. Our observations demonstrated the consistent presence of two clusters of c-Myc-expressing cells in anagen follicles, located in two annular regions of the inner root sheath, at the border between cells characterized by putative trichohyalin granules and cells which are keratinized. The lower group belongs to Henle's layer, while the upper group belongs to Huxley's layer. c-Myc oncoprotein seems to favour apoptosis/differentiation and may be a marker for terminal differentiation of trichocytes, at least in the inner root sheath. Our findings agree with the interpretation that the complex morphology of the hair follicle reflects its complex function; the extrusion of a highly organized multicellular structure, the hair shaft, driven by another highly organized multicellular structure, the inner root sheath.

Delayed cutaneous reaction to jellyfish.

A 57-year-old woman presented with a widespread papulonodular eruption. The dermatitis had appeared about 1 week after her return from a trip to the Red Sea, where she had come into contact with a shoal of unidentified jellyfish; however, that contact had not been followed by cutaneous lesions and/or symptoms. The patient also stated that she had had previous contacts with jellyfish during other trips to exotic seaside resorts. The dermatitis was characterized by papulonodular lesions, round or oval in shape, of a few millimeters in diameter, with a color ranging from pink to red to brown, and with a smooth and regular surface. The lesions were grouped in an apparently random fashion (Fig. 1) or arranged linearly (Fig. 2). The patient complained of pruritus and burning. Histopathologic examination showed the presence of some necrotic keratinocytes; in the upper and mid dermis, edema and a predominantly perivascular and periadnexal lymphohistiocytic infiltrate, with numerous neutrophils and eosinophils, were observed (Fig. 3). The patient was treated with hydroxyzine (37.5 mg/day) and hydrocortisone butyrate, which resulted in the rapid disappearance of the symptoms; however, the cutaneous lesions persisted for about 3 weeks.

Case report. Tinea corporis purpurea.

We report a case of tinea corporis purpurea localized to a calf in a 36-year-old woman. The patient, who was also affected by mild superficial venous insufficiency of lower limbs, complained of intense pruritus. Microsporum canis was the aetiological agent. Clinically atypical varieties of tinea corporis were sometimes reported in the literature, particularly in HIV-positive patients, although they are uncommon in immunocompetent patients; in particular, tinea corporis purpurea is very rare.

Evidence of retroviral involvement in an Italian patient with Ofuji's disease.

Ofuji's disease, also known as 'eosinophilic pustular folliculitis', is a rare inflammatory skin disorder of unknown aetiology, which affects mostly adult Japanese males. Only few Caucasian patients have been described so far. We report the case of a 44-year-old Italian woman with Ofuji's disease who had circulating antibodies against the recombinant envelope glycoprotein (Rgp46I) of HTLV-1. By means of a very sensitive nested PCR, the tax region of HTLV-1, but not other regions, was found in peripheral blood mononuclear cells. Our observations suggest that a retrovirus, closely related to HTLV but not yet identified, could be involved in the pathogenesis of the disease in this patient.

Localized peeling skin syndrome: case report with ultrastructural study.

We report a young woman in whom the history, clinical features, histopathological and ultrastructural findings led to a diagnosis of peeling skin syndrome (PSS). PSS is a rare and not well classified genodermatosis, mainly characterized by the spontaneous separation of the stratum corneum from the stratum granulosum. The unusual feature in our patient was the strict localization to the palm. PSS has been described as a more generalized disease frequently sparing palms and soles. We propose the diagnosis label of 'localized PSS' for this previously undescribed variant of a rare keratinization defect.

Skin manifestations caused by pigeon ticks (Argas reflexus).

Three adult patients (one woman and two men) presented with polymorphous skin manifestations caused by pigeon ticks (Argas reflexus). These manifestations were characterized by wheals with a central hemorrhagic point in the first patient, crusted-ulcerative lesions in the second, and pustular lesions in the third patient. We observed specific IgE against a somatic extract (antigen A) and the saliva (antigen B) of A. reflexus in two patients.

Albendazole: a new therapeutic regimen in cutaneous larva migrans.

BACKGROUND: Various therapeutic modalities have been used to treat cutaneous larva migrans, including physical treatments (cryotherapy), topical drugs (tiabendazole), and systemic drugs (tiabendazole, albendazole, and ivermectin). Physical treatments are often ineffective and not devoid of side-effects. Topical tiabendazole is difficult to find in many countries; it is effective orally but frequently causes side-effects. Ivermectin has been used in a small number of patients. METHODS: Eleven (six men and five women) adult patients with cutaneous larva migrans characterized by multiple and/or diffuse lesions were treated with oral albendazole (400 mg daily for 7 days). No other topical or systemic drugs were used and no physical treatment was given. RESULTS: All patients were cured at the end of treatment. No side-effects were complained of or observed, and no laboratory abnormalities were recorded. No recurrences were observed. CONCLUSIONS: Albendazole is effective in the treatment of cutaneous larva migrans characterized by multiple and/or diffuse lesions. This new therapeutic regimen can reduce the number of no responses and recurrences, sometimes observed following shorter (e.g. 3-5 days) treatments with albendazole. The longer duration of treatment is not accompanied by the appearance of new and/or more severe side-effects.
