Interstitial granuloma annulare triggered by Lyme disease

We present a case of a man in his 60s with a three-week history of progressive targetoid plaques on his arms, legs, and trunk. Skin biopsy demonstrated interstitial granuloma annulare. Additional testing revealed IgM antibodies to Borrelia burgdorferi on western blot suggesting interstitial granuloma annulare was precipitated by the recent infection. Lyme disease is an uncommonly reported association with interstitial granuloma annulare.

H, Heylen D Abstract Wild birds are frequently exposed to the zoonotic tick-borne bacteria Borrelia burgdorferi sensu lato (s.l.), and some bird species act as reservoirs for some Borrelia genospecies. Studying the tropism of Borrelia in the host, how it is sequestered in different organs, and whether it is maintained in circulation and/or in the host's skin is important to understand pathogenicity, infectivity to vector ticks and reservoir competency.We evaluated tissue dissemination of Borrelia in blackbirds (Turdus merula) and great tits (Parus major), naturally and experimentally infected with Borrelia genospe...

Apodemus spp. (n = 83) and Myodes glareolus (n = 22) were infested by Ixodes ricinus (192 larvae and two nymphs), Dermacentor marginatus (179 larvae and 29 nymphs), and Ixodes trianguliceps (three larvae and two ny...

Conclusions: Despite raising awareness of Lyme borreliosis, late forms of the disease such as ACA are still observed. Acrodermatitis chronica atrophicans skin lesions may be located in non-characteristic areas, e.g. abdominal skin. Symptoms are not irritating or painful, therefore patients do not seek medical help. The effect of antibiotic treatment varies. PMID: 30429707 [PubMed]

In conclusion, tick-mediated infections can trigger GA in some cases, while correlation of either Borrelia or Chlamydiales with morphea is unlikely. PMID: 29110020 [PubMed - as supplied by publisher]

We report an atypical case of European LCLB, suggesting that ACA is not the only possible presentation of LCLB. The diagnosis of ACA is often clinically missed for months or years, and may be mistaken at the inflammation phase for vascular disorders, erysipelas or bursitis/arthritis, and at the atrophic phase for lichen sclerosus atrophicus, morphoea or anetoderma. To our knowledge, no such tumorous LCLB has previously been described.

Authors: Ohn J, Park SY, Moon J, Choe YS, Kim KH Abstract Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal eviden...

by Eva Ru žić-Sabljić, Vera Maraspin, Daša Stupica, Tereza Rojko, Petra Bogovič, Franc Strle, Tjaša Cerar The isolation ofB.burgdorferi sensu lato requires the use of complex cultivation media. The aim of the study was to compare the usefulness of BSK-H (a commercial medium produced by HiMedia, India) and MKP medium. MKP and BSK-H media were prepared in accordance with the relevant protocols.Borrelia strains and skin culture biopsies were simultaneously inoculated into both media, incubated and checked for growth. Borrelial growth characteristics, isolation rates and characteristics of the isolated borre...

Hovius Ixodes ticks transmit Borrelia burgdorferi sensu lato (s.l.), the causative agent of Lyme borreliosis (LB). These tick species also transmit Borrelia miyamotoi, which was recently found to cause infections in humans. We were interested in the prevalence of B. miyamotoi infection in ticks and natural hosts in the Netherlands, and to what extent ticks are co-infected with B. burgdorferi. In additi...

aacute; L, Sprong H, Kazimírová M Abstract Borrelia miyamotoi causes relapsing fever in humans. The occurrence of this spirochete has been reported in Ixodes ricinus and wildlife, but there are still gaps in the knowledge of its eco-epidemiology and public health impact. In the current study, questing I. ricinus (nymphs and adults) and skin biopsies from rodents captured in Slovakia were screened for the presence of B. miyamotoi and Borrelia burgdorferi s.l. DNA. The prevalence of B. miyamotoi and B. burgdorferi s.l. in questing ticks was 1.7 and 16.9%, respectively. B. miyamotoi was detected in Apod...
