An 8-year-old, previously healthy girl presents to the emergency department (ED) with a rash “that looks likes bruises” and joint pain.  The red patchy rash is not painful and not pruritic. What's the diagnosis?

Rash triggers joint pain in an 8-year-old girl

**Editor's Note** Please note that starting January 1, 2025, we will be switching to an online-exclusive publication process. This will allow us to publish case submissions quicker without having to deal with the variables that come along with print publication. All cases will still be eligible for print publication consideration, but publication in our print magazine is not guaranteed and will be up to the editor's discretion. 

Do you have a puzzling pediatric case that you’d like to share with the readers of 

We are looking for intriguing diagnoses that have stumped the experts—a diagnostic “Puzzler”—to help our physicians enhance their day-to-day practices. If you have such a story to tell, tell us.

Here’s what to do: Before you begin, we suggest that first you review the Puzzler 

https://www.contemporarypediatrics.com/case-studies

. Please note the specific style required for writing Puzzler manuscripts.

Next, prepare a draft of your case, including a summary of the presenting symptoms, a case overview, a 

table of the differential diagnosis (MANDATORY)

, and the special aspects of your case that qualify it as a Puzzler, and send it to us. Please note that the differential diagnosis table should also be discussed in the body text. We’ll review your draft and let you know what you need to add or revise before we send the manuscript to peer review for evaluation.

Puzzlers vary in length, and we suggest a minimum of 1,200 words up to a maximum of 2,000 words, but that is because of the complexity of some cases and whether some patients returned for many assessments before their diagnoses were determined. Also, some authors describe the pathophysiology of the differentials in great detail. Please also note no more than 3 authors are allowed per article.

What's most important is to show us the process that you used to analyze the case, including:

Why you decided to order certain tests and why you did not order others.

Peer consultations or why you elected to contact other specialists.

Lab values including vital signs or blood tests.

Labs and values if your patient was attended to in the emergency department or other hospital departments such as radiology or neurology.

Discussion related to the possible diagnoses.

Final diagnosis, treatment, prognosis, and follow-up.

Remember to indicate numbered citations within the body of the text and include a complete list of corresponding literature/references at the end of the manuscript. (Do not use any citation management programs or unlink them.) 

Limit references to 25. No references (unless it is a seminal study) can be older than 10 years.

We prefer primary research as references, but some cases are so obscure that authors will need to pull from a variety of sources. However, 

. Be advised that peer reviewers are adamant that the disease/disorder you describe was actually diagnosed and not determined by index of suspicion on the basis of ruling out various differentials. We use AMA11 as our publication style, which uses superscript citation numbers and a corresponding numbered reference list. Please create your citations and references in this style.  Check this recent article posted online at 

https://www.contemporarypediatrics.com/view/the-rx-of-adhd

 for examples of reference style. IMPORTANT NOTE WITH AMA 11TH EDITION: PLEASE PUT DOI OR WEBSITES/URLS AT THE END OF THE REFERENCE LINE.

When you send your draft manuscript, also 

. These image files must be high-resolution jpg or tiff files (minimum of 300 dpi) and as large in size as possible. We suggest a minimum of 7 horizontal inches. The images must be original photos with clear permissions to use, not images from copyrighted sources. Send as separate attachments with your e-mail submission; do not embed images into your manuscript document.

After we receive your manuscript, our editors and peer reviewers will review your draft and let you know if we accept your submission for publication. 

Puzzler is one of the departments for which we receive the most submissions, so it may be several months after submission before you receive feedback from us.

If we do accept your submission for publication, we will contact you with further instructions.

Send your submissions in Microsoft Word format to

In November 2023, an otherwise healthy 11-year-old boy presented to the clinic with the chief complaint of testicular discomfort. He reported mild testicular pain that worsened with physical activity, and he denied the presence of dysuria, urinary urgency, or frequency. He was recently evaluated by ENT for an episode of epistaxis, which was benign and resolved without requiring cauterization. His medical history was otherwise unremarkable, notable only for molluscum contagiosum at5 years of age and a few episodes of streptococcal pharyngitis and otitis media.

His vital signs in clinic were within normal limits, and the only additional finding at this time was a nontender, nonpruritic, and nonpalpable petechial rash on the bilateral lower extremities. His mother observed that the rash appeared to fluctuate with his activity level, worsening during periods of increased stress or activity.

Given the presence of petechiae, an initial workup was initiated, including a complete blood count (CBC), comprehensive metabolic panel (CMP), prothrombin time (PT), and partial thromboplastin time (PTT). A point-of-care urinalysis performed in the clinic revealed traces of blood in the urine. The patient appeared well and did not show any other signs of illness. He was diagnosed with viral epididymitis while pending laboratory results. He was advised to remain hydrated and to return for follow-up if his symptoms persisted or worsened. His mother agreed with this plan and committed to closely monitoring his rash.

Over the following week, he returned to our clinic. His rash had progressed, spreading to his thighs, buttocks, and the distal shaft of his penis. All of his previous labs were within normal limits, and additional workup was initiated, including a platelet function assay and measurements of serum IgA, C3, and C4 levels, along with a repeat urinalysis.

A 6-day-old male with history of waxing and waning urticarial rash presents to the general pediatrician’s office for evaluation. The parents describe the rash as red, raised skin lesions that become flat and congregate, lasting several hours to days, resolving without leaving marks and then appearing in new areas. The rash began shortly after birth, and it does not seem to bother the patient. The parents deny any other concerns, including vomiting, fever, joint swelling, oral ulcers, or irritability. The patient is breastfeeding well and has normal urination and bowel movements.

On review of the nursery notes, it appears that at 9-hours of life the patient developed a rash that started as small, blanching, erythematous, circular macules on the legs; gradually increasing in size and number; becoming raised and coalescing to large, diffuse patches on the legs, back, chest, face, and soles that resolved within several hours. The patient was born to a 30-year-old gravida 1 mother at 40-weeks gestation via spontaneous vaginal delivery. The parents are without consanguinity or family history of autoimmune or inflammatory diseases. The pregnancy was complicated by maternal hypothyroidism and group B Streptococcus positive status, with the mother adequately treated with levothyroxine and intrapartum antibiotics.

A 23-month-old female presented with a 3-day history of cough, rhinorrhea, and increased work of breathing. Initially, she was treated for bronchiolitis at an urgent care center, where a nasopharyngeal swab identified adenovirus. Despite initial treatment, the patient's condition worsened, and she required oxygen supplementation via nasal cannula for oxyhemoglobin desaturation. Her hypoxemia further deteriorated, necessitating an increase in oxygen supplementation (

On physical examination, the patient showed signs of respiratory distress. A chest X-ray (CXR) revealed opacities in the right middle and lower lobes. The patient's condition improved with supportive care, and she was discharged after several days in the hospital. 

However, 9 months later, due to recurrent wheezing, she was referred to the pulmonary service for further evaluation. A follow-up CXR, taken 3 months after the initial infection, demonstrated complete opacification of the right hemithorax with a mediastinal shift to the right, as well as collapse of the right upper and middle lobes.

This episode is highlighted by a discussion surrounding several headlines in the infectious diseases and vaccine space, from changes to the CDC's Advisory Committee on Immunization Practices (ACIP) to updated vaccine recommendations and vaccine hesitancy.

Tan and Jones highlight the challenges that health care providers have been faced with in both the practice setting and in communicating with patients and their families, who are also navigating unfamiliar information, at times misinformation, opinions, and distrust in the medical field. 

"With the ACIP, we have a new committee, and I am worried, I'm frustrated, as many of us pediatric providers are, I'm sure," said Jones. "I don't know what is coming, and there is a total level of uncertainty about how my practice, how the care of my patients, can be impacted by these potential changes, by the things that are being recommended or not recommended."
