Unclear Diagnosis from Skin Biopsy
A 29-year-old woman with a body mass index of 20 has been experiencing ongoing episodes of petechiae. Recently, a biopsy was performed on one of the areas where petechiae were present. While I await feedback from the dermatologist, I'm aware that the results may not provide definitive answers, yet they do not appear alarming at this point. The findings include a lesion measuring 0.1 cm by 0.1 cm, which is pigmented, slightly elevated, and smooth with irregular edges, situated eccentrically on the skin. Only an H and E stain was conducted on the sample, revealing results that indicate “mild superficial perivascular chronic inflammation and extravasated erythrocytes,” with “no features of vasculitis noted.” If this were your patient, would you pursue further investigation or consider the findings benign?

The findings from your biopsy suggest inflammation and extravasated erythrocytes (which means blood has leaked into the surrounding tissue), but there are no signs of serious conditions like vasculitis. While it’s understandable to feel anxious about unclear diagnoses, it’s reassuring that the dermatologist reported no alarming features.
Explanation:
In your case, the lesion is small, has a benign appearance, and the biopsy results indicate inflammation without evidence of malignancy. Petechiae can occur due to various benign causes, including minor traumas, certain infections, or even benign skin conditions. The mild inflammation might suggest a reaction to something rather than a serious health issue.
Next Steps:
-
Monitor Symptoms: Keep an eye on the affected area for any changes in size, color, or symptoms like itching or pain. Note any new petechiae or changes elsewhere on your body.
-
Symptom Diary: Consider maintaining a record of when the episodes occur, their duration, and any potential triggers you might notice, such as physical activity, skin irritants, or medications.
-
Follow-Up Consultation: Once you receive feedback from the dermatologist, review it in detail. If the findings remain ambiguous or if symptoms persist or worsen, further investigations may be warranted.
-
Healthy Practices: Ensure you’re maintaining good skin care practices such as moisturizing, avoiding irritants, and protecting your skin from trauma.
-
Stay Informed: If you feel uncertain after discussing your results with your dermatologist, don’t hesitate to seek a second opinion or ask about additional tests if needed.
It's completely normal to feel unsettled while waiting for further information. Reassuringly, the current findings don’t indicate any immediate concern, but keeping track of your symptoms can provide more insight and facilitate ongoing discussions with your healthcare provider.

Enigmatic Skin Condition
I’ve recently stumbled upon this community and wanted to share my experience! Here's my story: - At the age of 22, I noticed peculiar marks appearing on both of my hands. They weren’t itchy or red, but there was some slight swelling in my hands. - I felt perfectly healthy otherwise, without any additional symptoms. - These marks extended from my fingertips to about the halfway point on my forearms. - Over a span of two weeks, they began as subtle symptoms beneath the skin and eventually surfaced, with some areas developing blisters. - Prior to this, I had experienced chicken pox as a child at three years old and shingles on my back at the age of 19. Since then, I have had no other skin-related problems, and I’ve never dealt with cold sores, warts, or anything similar. - I consulted a general practitioner at the time, who speculated that it might be stress-related as he eliminated the possibility of contact dermatitis. This was shortly after I graduated from college about a month earlier. This incident occurred back in 2008, and I haven't encountered anything like it again. I would appreciate any insights or thoughts you may have!

Identifying Mysterious Nose Spots
Greetings everyone! I'm a 32-year-old woman, and I don't take any medications. For several months now, I've been dealing with two spots on my nose that simply won’t go away. I maintain a skincare routine that includes cleansing, toning, and moisturizing, but despite my efforts, these spots remain persistent. They lack a noticeable head, which makes it impossible for me to pop them, and they neither cause discomfort nor have they grown larger over time. I woke up one day to discover them, and they’ve been there ever since. My apologies for the poor image quality.

Evaluating a Suspicious Spot on the Skin
At 33 years old, I've recently observed a pale spot developing on my forehead. This soft, raised area has been increasing in size rapidly and was not present back in October. I've noticed it subtly emerging in some earlier photos as well, highlighting the change over time. The spot does not exhibit any symptoms like itching, scabbing, or flaking. During summer months, I do spend considerable time outdoors, but I consistently apply sunscreen for protection. My esthetics specialist, whom I consult every other month for facials, mentioned that this spot does not appear to be related to acne and does not seem to contain any fluid or resemble milia. Given my upcoming medical appointments, I’m attempting to determine which ones should be addressed first. I discontinued spironolactone two months ago for managing elevated androgen levels and borderline polycystic ovary syndrome (PCOS), after being on it for approximately two years. Additionally, I stopped taking Wegovy one month ago as my husband and I are intending to try for a child following the appropriate waiting period. Currently, I am not taking any vitamins, medications, or supplements.
