Background Hookworm-related cutaneous larva migrans (CLM) is characterized clinically by erythematous and slightly raised tracks, located especially on the feet. These tracks may be single or multiple, linear or serpiginous, more or less ramified and intertwined. The length is variable (up to many cm); the width ranges from 1 mm to 4 mm. Tracks are often accompanied by severe pruritus. Methods Three adult Caucasian patients recently returned from trips to Malaysia and Thailand, presented with follicular CLM. The disease was characterized clinically by follicular, erythematous, small papules that were sometimes topped with vesicles or pustules, located on the buttocks. Pruritus was severe. Results Histopathological examinations revealed a perifollicular infiltrate predominantly consisting of lymphocytes and eosinophils. All patients were successfully treated with oral albendazole (400 mg/day for seven days). In the first patient, two courses were necessary. Conclusions Dermatologists should be aware of the existence of this rare and atypical, although emerging, clinical presentation of hookworm-related CLM.

Tungiasis is an infestation caused by penetration of the skin by the gravid female of the flea Tunga penetrans Linnaeus 1758 (Insecta, Siphonaptera: Tungidae). Tunga penetrans is currently found in Central and South America, sub-Saharan Africa, and Central Asia. Prevalence is very high in Brazil. We present a case of tungiasis in an Italian beach volleyball player who acquired the infestation in Brazil. (J Am Podiatr Med Assoc 101(4): 353–355, 2011)

We evaluated retrospectively the efficacy and tolerability of oral albendazole (400 mg/day for 1 week) in 78 patients with hookworm-related cutaneous larva migrans characterized by multiple and/or extensive lesions. The diagnosis was based on history and the clinical picture. Neither topical or systemic drugs nor physical treatments were used. All patients were followed-up for at least 3 months after the therapy. All patients were cured at the end of the therapy. The disappearance of pruritus was reported after 2-3 days and skin lesions after 5-7 days of therapy. One patient reported nausea and abdominal pain; another patient reported worsening of pruritus: in both cases it was not necessary to stop the therapy. No recurrences were observed during follow-up. One week of therapy with 400 mg/day oral albendazole is very effective (cure rate: 100%) in patients with cutaneous larva migrans characterized by multiple and/or extensive lesions. This therapeutical regimen is not accompanied by the appearance of new and/or more severe side effects.

We report a case of leishmaniasis localized to the upper lip in a 77-year-old Italian man. The disease was characterized by a severe swelling which involved the right side of the upper lip. The swelling was slightly erythematous with crusts and scaling. Consistency was parenchymatous-hard. The lesion was asymptomatic. Histopathologic examination showed an inflammatory infiltrate consisting of lymphocytes, histiocytes, and plasma cells. Several Leishmania spp. amastigotes were observed in the cytoplasm of macrophages. Cultural examination on Novy-MacNeal-Nicolle medium was positive for Leishmania spp. Polymerase chain reaction was positive for Leishmania infantum. The patient was treated with i.m. N-methylglucamine antimonate, with complete remission in approximately 6 weeks. During follow-up of 9 months, no relapses were observed.

The authors describe two cases of cutaneous larva migrans associated with fever in two HIV-positive patients. Laboratory and instrumental examinations allowed to exclusion of other possible causes of fever. The presence of fever in patients with cutaneous larva migrans might represent a marker of HIV infection.

Summary Objectives The purpose of this study is to present the ‘chronic' or ‘persistent' form of hookworm-related cutaneous larva migrans. Methods From 1998 to 2011, 13 patients were seen in our department with clinically typical hookworm-related cutaneous larva migrans that had been present for more than 5 months and that, because of the absence of pruritus, had never been treated. Results The duration of hookworm-related cutaneous larva migrans ranged from 5 to 14 months (mean 7.8 months) in these 13 patients (10 males and three females, aged 23–55 years). The infestation was acquired in Brazil (three patients), Jamaica (three patients), Mexico (two patients), Tanzania (two patients), Thailand (two patients), and Martinique (one patient). The infestation was located on the feet in 10 patients; one of these patients also presented tracks on the back and another presented tracks on a knee. The chest (two patients) and thigh (two patients) were also involved. All patients presented with clinically typical hookworm-related cutaneous larva migrans: seven patients had one track and six patients had two tracks. Laboratory and instrumental examinations were within the normal range or negative. Histopathological examination revealed edema in the papillary and upper dermis, and a perivascular and perifollicular infiltrate in the upper dermis, consisting mainly of lymphocytes and eosinophils. No larvae were detected. Conclusions This can be considered the ‘chronic' or ‘persistent' form of hookworm-related cutaneous larva migrans. Some pathogenetic hypotheses are suggested.
