Insights Needed on Possible Rare Tumor in My 4.5-Month-Old Daughter
My baby girl, at 4.5 months old, currently weighs 13 pounds and measures approximately 24 inches in length. She is not on any medications, has a clean bill of health with no previous medical concerns, and is reaching all her developmental milestones. Being formula-fed, she is growing steadily and has not been exposed to any smoke or harmful environmental substances. A few weeks ago, during a standard checkup, her pediatrician discovered a firm, circular mass located in her lower abdomen, situated between her navel and genitals. Although it was not externally visible, it was easily felt beneath the skin. Following this, we proceeded with an ultrasound that revealed the mass to be subcutaneous—located beneath the skin but above the muscle. The results showed it was vascular, indicating blood flow, and it seemed to be causing a slight mass effect. Fortunately, all her other organs appeared normal, and she exhibited no symptoms; her eating, toileting, and behavior were unaffected. We were directed to a pediatric surgeon, who assessed the mass and deemed it too small for a lipoma or lipoblastoma. We were presented with two options: monitoring it or opting for surgical intervention. We opted for the surgery so that it could be both removed and analyzed. The procedure was carried out under general anesthesia and was considered a superficial operation, allowing her to return home the same day. She has been recovering remarkably well since then. Now comes the challenging phase of waiting for pathology results. We have been informed that it does not appear to be a typical cancer, as common malignancies have been excluded. However, the mass has been classified as unusual and is something they don’t usually encounter, prompting them to conduct further specialized tests. When we inquired about the possibility of it being cancerous, the surgeon estimated that it is a near fifty-fifty chance. It's a daunting time for us as we navigate this uncertainty. Our daughter is doing well and continues to exhibit her usual cheerful demeanor, but the suspense is profoundly difficult to bear. While I’m not seeking a diagnosis, I would appreciate any information regarding rare subcutaneous vascular tumors that could occur in infants of her age. Are there benign conditions that, although rare, might explain her situation? Thank you for any assistance you can provide!

It sounds like you are experiencing an exceptionally challenging time waiting for the pathology results regarding your daughter’s mass. I want to acknowledge the stress and anxiety that comes with uncertainty about your child's health. It's great to hear that she is doing well and maintaining her usual cheerfulness.
Based on the information you've provided, there are a few considerations regarding subcutaneous vascular tumors in infants:
Key Points
- There are rare benign vascular tumors, such as hemangiomas, that typically present as raised lesions but can sometimes be subcutaneous.
- Other possibilities might include vascular malformations or unusual tumor types that can arise in pediatric patients but are generally less common.
- The surgeon's assessment and your daughter's stability are positive signs, but obtaining the pathology results is essential for a clear understanding.
Explanation
Infants can develop a variety of subcutaneous masses, and while many are benign, some can be rarer and atypical. Hemangiomas are common in infants and usually resolve on their own, but when they're deeper beneath the skin or vascular, they may warrant more investigation, as you’ve seen with your daughter. The lack of symptoms and stable behavior you described are encouraging indicators.
Next Steps
-
Focus on Recovery: Continue to support your daughter during her recovery. Ensure she has a comfortable environment, and monitor her for any unusual signs or changes in her behavior, appetite, or activity.
-
Stay Informed: Keep communication open with your medical team. It's beneficial to continue asking questions as you await the pathology results. They can provide updates or further insights regarding the types of tests being performed and what you might expect next.
-
Emotional Support: Consider connecting with support groups or other parents who have faced similar situations. Sharing experiences can help alleviate some of the emotional burden.
-
Prepare for Results: Once you receive the pathology results, have a list of questions ready to discuss potential diagnoses, treatment options if necessary, and follow-up care. Understanding the nature of the mass will be crucial for moving forward.
-
Self-Care: Remember to care for yourself and your partner during this stressful time. Engage in activities that help alleviate stress and keep lines of communication open between you both.
Your proactive approach to your daughter’s health and well-being, along with your readiness to seek information, is commendable. Wishing you strength and clarity as you navigate this situation. Feel free to reach out for more information or support!

Sore Throat and Tonsil Discomfort for Three Weeks
For the past two weeks, I have been experiencing significant pain in my tonsils. After consulting with urgent care, I underwent tests for both strep throat and mononucleosis, but the results were negative. The doctor advised me to be patient as the discomfort was expected to subside on its own. Unfortunately, my condition worsened, prompting me to return to urgent care three days later. During this visit, I was prescribed dexamethasone, a type of steroid, along with a ten-day course of amoxicillin. Remarkably, my symptoms began to diminish within hours. However, just three days later, I am starting to feel the throat and tonsil pain return. I am still on the amoxicillin regimen. What could be causing this resurgence of pain, and what steps should I take next?
Concerns About Persistent Cough: Is It Cardiac Related?
Greetings everyone, I’m a 20-year-old male weighing 320 pounds, which qualifies as overweight. Having dealt with asthma for the majority of my life—although it’s generally mild—I typically rely on a nebulizer during occasions of typical chest colds. For some context, I came down with a cold around January 9th. Being on a college campus frequently means exposure to a variety of illnesses, and I suspect I contracted bronchitis, given the lasting cough and breathlessness I experienced for a couple of weeks afterward. However, I believed I had fully recuperated and moved on. Recently, since about Monday, I have noticed a return of my breathlessness along with a persistent cough and a sensation of fluid in my chest and throat. I find myself coughing as I attempt to clear my throat. This comes and goes, but it tends to intensify in the mornings right after I wake up and at night when I try to sleep. Additionally, I spend time with friends who smoke on occasion, and I initially thought that secondhand smoke might be a contributing factor. My concern has grown, and I’m unsure what to think. So, I’m reaching out for guidance: could this be residual effects from my cold in January, or should I be concerned that this might indicate a more serious issue related to my heart?
Hernia Diagnosis Without Follow-Up: A Conflicting Situation
A 22-year-old male recently visited the emergency room due to discomfort in his lower abdomen. Upon examination, the medical team was indecisive about whether he was experiencing an oblique muscle problem or a hernia. Surprisingly, they opted against performing a CT scan or ultrasound and did not schedule any follow-up appointments. To the best of my knowledge, hernias typically do not resolve themselves with merely the use of ace bandages or over-the-counter pain medication; surgical intervention is usually necessary for proper treatment. Is there a specific rationale behind their reluctance to pursue further diagnostic testing or surgery?
Experiencing Wheezing During Deep Breaths
Greetings, everyone! I'm seeking your insights on a particular issue I'm facing: I experience a wheezing sound only when inhaling deeply. Interestingly, it's noticeable on one side, and it's audible to others as well. I've never used tobacco or any other substances, nor do I consume alcohol. My weight falls within a healthy range, and I do not have asthma. Additionally, my oxygen levels are normal, and I don’t struggle with breathing; this situation is more of an irritation than a serious problem. I’ve recorded the noise, but I’m unable to share it here; it honestly resembles the sound of a rubber chicken. I would appreciate any thoughts or suggestions! Thank you in advance!
Unexplained Episodes of Abdominal Discomfort
Age: 28 Gender: Female Weight: 194 lbs Height: 5’7" Current Medications: Vitamin D, Fish Oil, B Complex Vitamins, Birth Control Pills, Vyvanse 30 mg Health Background: Asthma, Eczema, Gastroesophageal Reflux Disease (GERD) Since August 2025, I've experienced three occurrences of intense abdominal discomfort that necessitated visits to the emergency room for pain management. These episodes usually strike at night, escalating to unbearable levels within around 30 minutes. None of the sitting positions seem to provide relief, and gastrointestinal medications have proven largely ineffective. Only strong pain relievers seem to alleviate the suffering. After the peak of the pain subsides, my abdomen remains sensitive for more than three days. I can accurately identify the location of the discomfort, which appears to be between the midepigastric area and near the gallbladder. The pain is difficult to articulate, yet it presents as a severe burning and aching sensation. Interestingly, there does not seem to be any specific food intake related to these pain episodes. I underwent an H. Pylori breath test that returned negative results. Additionally, I had an esophagogastroduodenoscopy (EGD). Although the biopsies were also negative for H. Pylori, they did reveal residual liquid in my stomach and a small section of intestinal metaplasia. My complete blood count (CBC) and comprehensive metabolic panel (CMP) results were normal, except for elevated LDL levels, which I’m already aware of. My gastroenterologist has recommended a gastric emptying study (GES) to evaluate the functionality of my stomach. If results indicate no issues, we will then investigate the gallbladder. Are there alternative explanations for my symptoms? Should I be worried about autoimmune metaplastic atrophic gastritis (AMAG)? While I have been diagnosed with GERD, this pain feels distinctly different from the GERD-related discomfort. I am not entirely sure it is gastroparesis, even though I occasionally regurgitate if I eat too quickly; I do not experience nausea or malnutrition. I have researched extensively, and my symptoms align with biliary colic. However, I am anxious about the possibility of gallstones not appearing in the ultrasound. My gastroenterologist is not particularly concerned about the intestinal metaplasia, but being only 28 years old, I find this worrying. As a medical student, these painful episodes significantly hinder my studies and academic progress.
