What'sYour Diagnosis?

**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.

Poll: What's the diagnosis of this linear eruption on the leg of a 9-year-old girl?

 poll. Take a look at the following case below. After reading through the description, choose a multiple-choice answer and try to guess the correct patient diagnosis.

This case was presented by Rutva Vora, BS; and Monica Guirguis, DO.

A 2-month-old female was born after an uneventful pregnancy at 40 weeks’ gestation via vacuum-assisted vaginal delivery to a G2P1011 female. The patient’s APGAR scores were 7 and 9 at 1 and 5 minutes, respectively, at birth. No bleeding or other complications were reported during delivery. The newborn and mother were discharged two days after delivery without requiring NICU stay or interventions. The infant briefly developed a small soft palpable scalp swelling that resolved within days after delivery. The patient followed an otherwise uncomplicated growth progression since birth. She did exhibit mild reflux symptoms, which were managed with supportive care measures. Physical examination after delivery and subsequent exams revealed no abnormalities, including no signs of scalp swelling or injury.

At 8 weeks of age, the patient presented to the Emergency Department with a 3-day history of new-onset scalp swelling. The parents decided to seek medical attention after the swelling became noticeably enlarged. Parents denied any changes in her mental status, vomiting, fevers, lethargy, irritability, or any other new concerns. She did have symptoms of gassiness and fussiness that were unchanged from baseline. No history of trauma was reported, and there were no concerning signs suggestive of nonaccidental trauma. The patient appeared well, with a soft, fluctuant palpable subcutaneous fluid collection overlying the parieto-occipital scalp, without crossing suture lines. The anterior fontanelle was soft and non-bulging, and there was no hemotympanum.

An 18-day-old female presented to the ED with concerns of apnea, cyanosis, and decreased feeding. The mother reported intermittent cyanosis of the lips, pale-appearing skin, and suspected apnea episodes. Since birth, Mom states patients had retractions since birth, which the PCP reassured her was normal periodic breathing. She had nasal flaring and grunting a couple of days after discharge from the nursery. Mom has noticed she breathes quickly, in the 60s or 70s at times.

Initial vitals in the ED showed hypoxemia, tachypnea, and fluctuating oxygen saturations were between 65-100% on room air. A chest X-ray is shown (

Diagnose this 18-day-old female with apnea, cyanosis, decreased feeding concerns

An 18-day-old female presented to the Emergency Department (ED) with concerns of apnea, cyanosis, and decreased feeding. The mother reported intermittent cyanosis of the lips, pale-appearing skin, and suspected apnea episodes. Since birth, Mom states patients had retractions since birth, which the primary care provider (PCP) reassured her was normal periodic breathing. She had nasal flaring and grunting a couple of days after discharge from the nursery. Mom has noticed she breathes quickly, in the 60s or 70s at times.

On physical examination, the patient appeared to be in significant respiratory distress. Her oxygen saturation was 96% on high flow nasal cannula. She had severely decreased air entry bilaterally with subcostal retractions. A complete blood count and metabolic panel were within normal limits. A venous blood gas showed the following: 7.24/74/51/35.

Due to an x-ray obtained while the patient was on the pediatrics floor, there were concerns for an underlying tension pneumothorax. The patient was transported to the PICU, where upon admission an urgent needle decompression was performed. However, upon performing the same, there was no change in the patient's vitals, nor was there a gush of air emitted from the needle that was placed. To further delineate the cause of the findings seen on the x-ray, a CT chest with IV contrast was performed (

). This image study confirmed the diagnosis of left upper lobe congenital emphysema. Her condition was managed with surgical resection of the left upper lobe emphysematous lobe. Her respiratory status improved after surgical resection with her breathing without any distress.

The patient’s condition improved with surgical resection of the overinflated left upper lobe. 

Congenital lobar emphysema (CLE) or congenital alveolar overdistension is a rare pulmonary disorder that primarily affects neonates, characterized by hyperinflation of one or more lobes of the lung, most commonly the left upper lobe.

 The condition is caused by a defect in the airway cartilage that leads to partial obstruction of airflow, resulting in air trapping and over-distention of the affected lobe. This can cause compression of the surrounding lung tissue and mediastinal structures, leading to respiratory distress, as was observed in this case.

The diagnosis of CLE can be challenging as it may mimic other conditions such as tension pneumothorax or pulmonary interstitial emphysema.

 Chest X-rays and CT scans are the imaging modalities of choice to confirm the diagnosis. In this patient, the initial X-ray raised suspicion for CLE, which was later confirmed by a CT scan showing hyperinflation of the left upper lobe and atelectasis of the left lower lobe. 

Management of CLE often begins with supportive care, such as oxygen supplementation or mechanical ventilation if necessary. However, the definitive treatment is typically surgical resection of the affected lobe, known as lobectomy. Surgical intervention is usually recommended when hyperinflation leads to significant respiratory compromise or when conservative management fails. In this case, the patient’s left upper lobe was resected.

This case emphasizes the importance of early recognition and intervention in neonates presenting severe respiratory distress. Timely surgical intervention, typically lobectomy, can be lifesaving and prevent long-term complications associated with untreated CLE.

A boy aged 10 years presented to the outpatient office with a history of painful nodules on the plantar surface of his bilateral feet 8 to 10 hours after spending time in a hot tub. He was unable to bear weight or put on socks and shoes due to his pain. The photos were taken soon after the painful and red papules appeared. The lesions affected the whole plantar aspect of both feet. Over the following 4 days, the nodules became less painful and red. 

Medical advice was sought on the fifth day of symptoms, and by this time, the child was improving clinically. He was stable with subcutaneous, mildly painful, fleshy nodules mostly populating the medial arch of the foot. His remaining clinical examination results were within a normal range. Further questioning of the child’s mother revealed that other children exposed to the hot tub experienced painful feet but without lesions. 

Due to the patient’s improving symptoms and the self-limiting nature of the illness, no tests or labs were ordered as the child was not acutely ill. No peer consultations or specialists were utilized.
