Persistent Bruising Beneath a Long-Standing Mole
Age: 47. Skin tone: White/olive. Overall health appears to be good. Height: 5'6", Weight: 140 lbs. Approximately six to nine months ago, I discovered a dark spot on my back that caught my attention. Over time, I noticed that this mark seemed to gradually increase in size and deepen in color. Additionally, I observed a bruise measuring about 1.5 to 1.75 inches directly beneath it. This bruise has not exhibited the typical dark purple hue; rather, it has consistently remained a lighter shade of purple or blue. Importantly, this bruise did not exist prior to noticing the mole, which was likely pea-sized, slightly elevated, and reminiscent of dark chocolate in color. Last Wednesday, I consulted a dermatologist regarding my concerns. He examined the area using a specialized light and assured me that it appeared normal. Despite my worries, he took a small sample for lab analysis, promising to send it for further evaluation. I am still awaiting the results. During the appointment, I also brought up the persistent bruise. The dermatologist acknowledged its presence but seemed to dismiss my concern, expressing that it was nice to meet me before concluding the very brief consultation, which lasted no more than five minutes. I'm left feeling puzzled. It seems unusual that the bruise and mole occupy the exact same spot, and the bruise continues to show no signs of fading, maintaining its usual appearance. Any insights or suggestions would be appreciated.

It's understandable to feel concerned about changes in your skin, especially when there's a new mole and a persistent bruise involved. While you’ve taken an important step by consulting a dermatologist, there are some key points to consider while you await the lab results.
Main Points:
- Recent changes in moles should always be monitored, especially if they grow or change in color.
- A persistent bruise that does not fade may require further investigation, especially if it's associated with a new mole.
Explanation:
- Moles can undergo changes for various reasons, including benign factors like hormonal changes, sun exposure, or irritation. The fact that you have a history of a mole that is changing in size and color is significant enough to warrant further observation, which you've correctly initiated by seeking a biopsy.
- The bruising you describe, particularly remaining in one spot and not fading, can occur for several reasons. It could be due to localized trauma, a bleeding disorder, or irritation from the mole itself. Given your description of the bruise, it's good that you mentioned it to your dermatologist, even though you felt it was dismissed.
Next Steps:
- Monitor the Bruise and Mole: Keep an eye on both the mole and the bruise. Take pictures weekly to document any changes in size, color, or shape.
- Manage Any Symptoms: If you notice new symptoms, such as pain, itching, or if the bruise gets larger, make note of this as it will be important information for your healthcare provider.
- Follow Up on Biopsy Results: As you await the lab results, don’t hesitate to reach out to your dermatologist's office for any updates or if you have worsening concerns.
- Consider Seeking a Second Opinion: If you continue to feel uneasy or your bruise does not improve, consider making an appointment with another dermatologist for a comprehensive evaluation. It's completely reasonable to seek a second opinion when it comes to skin changes.
While waiting can be anxiety-provoking, being proactive about these changes is the best course of action. Please remember to follow up as necessary and take care of your skin health. Let me know if you have any further questions or concerns!

Rare Citrobacter Koseri Skin Infection: A Unique Case
An 18-year-old male, standing at 5 feet 10 inches, reported a rather unusual skin condition. Approximately a month ago, he had a facial lesion evaluated, and the culture revealed the presence of Citrobacter koseri. This diagnosis took his doctor by surprise, as he had never encountered this particular bacterium in relation to skin infections before. Despite this unexpected finding, the physician remained relatively unconcerned, recommending a standard over-the-counter acne wash as the course of action. Interestingly, the patient continues to experience new lesions intermittently, even weeks later, with no accompanying symptoms. Research indicates that C. koseri is not typically found on human skin and such instances where it leads to skin conditions are exceedingly rare. The individual discovered only a few documented cases globally, highlighting the rarity of his situation. At 18 and in good health otherwise, he expressed uncertainty about whether to let the issue resolve on its own or to seek further medical evaluation and treatment. He is reaching out for insights from anyone who may have faced a similar experience or to gather opinions on potential next steps to take in managing this perplexing situation.

Recurring Ear Inflammation Concerns
A 24-year-old male, standing at 180 cm tall and weighing 80 kg, has been grappling with ear inflammation for an extensive period, spanning a total of 12 years. Recently, however, the condition has intensified, especially over the last four years. Residing in the Middle East, the inflammation primarily affects his left ear, though it occasionally involves both ears. Over the past three years, he has experienced this issue on a monthly basis without any accompanying fever, but every three months it escalates, causing severe pain along with fever symptoms. There are no known underlying medical conditions, and his current prescription includes Esomeprazole. He has made several observations related to his condition: visiting the hospital for ear wax cleaning appears to prevent inflammation for the subsequent three months. Conversely, scratching the ear with his hand or a tissue heightens the likelihood of inflammation, as he refrains from using any at-home ear-cleaning devices. He occasionally suffers from intense itching sensations within his ear. Additionally, he has noticed that sleeping in a small room with air conditioning seems to raise the risk of inflammation. His ear wax tends to be quite dry, which leads him to suspect that his ears dry out quickly, potentially making them more susceptible to bacterial infection. Due to practicality concerns, he prefers not to use ear drops daily to maintain moisture. Instead, he is exploring alternative methods to ensure skin hydration without the use of oil-based drops. He wonders if there are products similar to creatine, which promotes water retention in muscles, that could aid skin hydration. He also considers whether potassium supplements might be a beneficial avenue to pursue.
Experiencing Unilateral Goosebumps After Taking Midodrine for POTS
This year, I began using midodrine as part of my treatment for POTS and was aware that this medication can lead to goosebumps. However, I've recently observed that the goosebumps only appear on the right side of my body—specifically my right arm and leg. In contrast, the left arm and leg remain entirely smooth after I take the medication. This phenomenon has come to my attention during my last few doses, and previously I hadn't thought to check both sides of my body, leaving me uncertain whether this is a new occurrence or something that has been happening all along. Since starting midodrine, my blood pressure has consistently stayed within the normal limits. My concern stems from having heard that similar symptoms could indicate neurological problems. Should I be alarmed about this observation, or is it advisable to wait until my next cardiologist appointment to discuss it? As for my current medications, I am taking 5 mg of midodrine, along with doses of methylphenidate (10 mg), buspirone (10 mg taken twice daily), nortriptyline (25 mg), quviviq (50 mg), and acetaminophen (1,000 mg). My diagnoses include POTS, fibromyalgia, ASD, ADHD, insomnia, and depression. My weight is 175 lbs and I stand at 5 feet 11 inches tall.
