RESUMO
INTRODUCTION: To assess the prevalence of nail involvement in children <16 years old with a confirmed diagnosis of scabies. STUDY DESIGN: Observational, prospective study in 7 French dermatology departments between June 2015 and January 2017. Children were included if they had scabies confirmed by dermoscopy and/or microscopy and if nails could be sampled. The first toenails and thumbnails as well as clinically affected nails were systematically sampled for microscopic examination. Individual data were recorded via a standardized questionnaire. RESULTS: A total of 47 children with scabies were included (26 females [55.3%], mean age 3.6 ± 4.0 years). Pruritus was present in 42 children (89.3%); the relapse rate was 38.3% (n = 18). In 3 infants (6.4%), Sarcoptes mites were revealed by dermoscopy or microscopy of the first toenails (2 cases) and a thumbnail (1 case), but nails were normal in 2 children. Two of the 3 infants had already received treatment for scabies in the previous weeks. CONCLUSION: Prevalence of nail involvement in children with confirmed scabies was 6.4%. Nails should not be overlooked during scabies treatment.

Myiasis is caused by the invasion of tissues or organs of men and animals by dipterous larvae. The disease is infrequent in Turkey. A case of a 65-year-old woman having been initially diagnosed with chronic psychosis, and found to have a left big toe nail invaded by the larvae of Calliphora spp., is presented. A total of 17 maggots were removed from the left big toe of the patient, which were then determined as Calliphora spp. The patient has undergone surgical withdrawal of both nails of her big toes, followed by the administration of oral prophylactic antimicrobial treatment. This is the second recorded case of subungual myiasis by Calliphora spp. in Turkey. Myiasis should be considered in patients with lower personal hygiene, especially with chronic psychiatric disturbances.

We report a case of a 71-year-old man infected at a nursing home who developed a bullous pemphigoid-like eruption with nail involvement. He was diagnosed by his family doctor as suffering from eczema and was treated with topical corticosteroids, then blisters started appearing. He was next diagnosed as suffering from bullous pemphigoid and treated with oral prednisolone, which worsened his condition. He was finally diagnosed as having crusted scabies with bullous pemphigoid-like eruptions and nail involvement at our clinic. He was then prescribed oral ivermectin (two doses of 12 mg ivermectin with a 1-week interval) and topical lindane (1%gamma-BHC in petrolatum) for scabies with 5% salicylic acid in plastibase as an additional treatment for the crusted lesions on his soles. He showed remarkable improvement in 2 weeks, and his nails showed complete recovery after 7 weeks of occlusive dressing treatment with 1%gamma-BHC. One and a half years later, the patient showed no sign of a recurrence of scabies. The histology of a blister taken from this patient was similar to that of bullous pemphigoid. Direct immunofluorescence showed immunoglobulin (Ig)G and C3 deposition at the dermoepidermal junction similar to that of bullous pemphigoid, but indirect immunofluorescence was negative. The bullous symptoms of this patient were considered to be due to the scabies, because the patient recovered completely after receiving treatment for scabies. Indirect immunofluorescent study is important to distinguish between scabies with blister formation and true bullous pemphigoid.

We report an unusual case of nail infestation by Liposcelis bostrychophila Badonnel in a 70-year-old woman with onychomycosis. Liposcelis spp., also known as booklouse, are tiny insects that feed on fungi, lichen and decaying materials. In this case, the loosened hyperkeratotic nail provided a favourable environment for these insects. This is the second report of human infestation by Liposcelis spp.
