Granuloma annulare-like reaction to the bacillus Calmette-Guerin vaccination

Generalized granuloma annulare after pneumococcal vaccination

Granuloma annulare may be caused by multiple triggers. Among these are vaccinations, which have been described as an infrequent cause of granuloma annulare. The authors report the first case of generalized granuloma annulare associated with pneumococcal vaccination in a 57-year-old woman, who presented cutaneous lesions 12 days after vaccination.

Granulomatous reaction following bacillus Calmette-Guérin vaccination: Successful response to clarithromycin

We report a 3-year-old girl with a delayed nontuberculous granulomatous reaction on a bacillus Calmette-Guérin injection site with dissemination to distant sites who showed a favorable response to clarithromycin used for 12 weeks with no recurrence on a follow-up of more than 2 years.

Immune-mediated adverse reactions to vaccines

Vaccination continues to be the single most important and successful public health intervention, due to its prevention of morbidity and mortality from prevalent infectious diseases. Severe immunologically mediated reactions are rare and less common with the vaccine than the true infection. However, these events can cause public fearfulness and loss of confidence in the safety of vaccination. In this paper, we perform a systematic literature search and narrative review of immune-mediated vaccine adverse events and their known and proposed mechanisms, and outline directions for future research. Improving our knowledge base of severe immunologically mediated vaccine reactions and their management drives better vaccine safety and efficacy outcomes.

Injection Site Lichenoid Dermatitis Following Pneumococcal Vaccination: Report and Review of Cutaneous Conditions Occurring at Vaccination Sites

Background

Cutaneous dermatoses and malignancies have occurred at the sites of vaccines.

Purpose

To describe a man who developed a lichenoid dermatitis at the pneumococcal vaccine injection site and to review cutaneous dermatoses and malignancies occurring at vaccination sites.

Methods

PubMed was used to search the following terms, separately and in combination: adverse, condition, cutaneous, dermatosis, dermatitis, injection, PCV13, pneumococcal, pneumonia, prevnar, reaction, skin, site, vaccination, and vaccine. All papers were reviewed, and relevant manuscripts, along with their reference citations, were evaluated.

Results

Several vaccines—including bacillus Calmette-Guerin, hepatitis B, influenza, leishmaniasis, meningitis, pneumococcal, smallpox, tetanus (alone and in combination with diphtheria, pertussis, polio, Haemophilus influenza type B or plague and yellow fever), and varicella-zoster—have been associated with post-vaccination site reactions. A 70-year-old male developed a lichenoid dermatitis that occurred at the pneumococcal vaccine injection site within 2 weeks after PCV13 vaccination; the erythematous nodule resolved spontaneously within 9 weeks following immunization.

Conclusions

Dermatoses at the injection sites of vaccines can be granulomatous, immunity-related conditions, infections, lichenoid, neutrophilic, or pseudolymphomatous. Basal cell carcinoma and squamous cell carcinoma are the most common vaccination site-associated malignancies; however, melanoma and sarcomas (dermatofibrosarcoma protuberans, fibrosarcoma, and malignant fibrous histiocytoma) are also smallpox vaccine-related site neoplasms. A cutaneous immunocompromised district that is created by vaccine-induced local immunologic changes is hypothesized to be the pathogenesis of vaccination site reactions.
