Bowen's Disease: The South Florida Skin Warning Patients Miss

If you've got a dry, scaly, reddish patch of skin that's been hanging around for months, maybe even years, and nothing you put on it seems to help, we need to talk about Bowen's disease. It's not a condition most people have heard of, which is exactly why it gets missed so often here in South Florida. Bowen's disease is the medical name for squamous cell carcinoma in situ. That second part, "in situ," is the key word. It means this is squamous cell carcinoma in its earliest possible form, sitting entirely within the top layer of skin and hasn't invaded any deeper. It's essentially a type of skin cancer paused at step one. Left alone, a small percentage of cases can progress into invasive squamous cell carcinoma, which is why catching it early matters so much. **Why This One Gets Mistaken for Something Else** Bowen's disease shows up as a slow-growing, scaly, red or reddish-brown patch, often flat, sometimes slightly raised, with a crusty or scabby texture. It can show up anywhere, but in our patients we see it most on sun-exposed areas: the lower legs, forearms, hands, scalp, and face. Here's the problem. That description sounds a lot like a patch of eczema, psoriasis, or even just a stubborn dry spot. Patients treat it with moisturizer, hydrocortisone cream, or just ignore it because it doesn't hurt or itch much. Meanwhile, the patch slowly grows, sometimes over years, without ever turning into something that looks urgently alarming. We've written before about persistent rashes that aren't eczema, and Bowen's disease belongs on that list of mimickers worth getting checked. **Who We See It In Most** Bowen's disease tends to show up in people with decades of cumulative sun exposure, which describes a huge number of South Florida residents. We see it most in patients over 60, fair-skinned individuals, and anyone with a long history of sunburns or outdoor work and recreation. It's also linked to HPV in some cases, particularly in patches that develop on skin not typically sun-exposed. If you've spent years boating, golfing, or just living the South Florida outdoor lifestyle without consistent sun protection, your risk goes up. We've seen this pattern play out in boating and fishing culture and in golfers who spend decades in the sun, and Bowen's disease fits right into that same story of slow-accumulating damage finally showing up on the skin. **How We Tell the Difference** The only way to know for sure what you're looking at is a biopsy. During your visit, we'll take a small sample of the patch under local numbing and send it to the lab. No guesswork, no "let's wait and see for another six months." If it comes back as Bowen's disease, we'll walk you through exactly what we found and what happens next, plain and simple, no jargon. Treatment options depend on the size and location of the patch, but generally include topical chemotherapy creams, cryotherapy (freezing), photodynamic therapy, or surgical removal. In many cases, treatment is straightforward and done right in the office. We'll tell you up front how many visits to expect and what your skin will look like while it heals. This condition shares a lot of biological overlap with the invasive form we've covered in our piece on squamous cell carcinoma striking South Florida skin, and it belongs in the same conversation as actinic keratosis, the other overlooked precancerous skin warning we see constantly in this climate. **Don't Wait for It to Change** The tricky part about Bowen's disease is that it doesn't scream for attention. It doesn't bleed, it doesn't hurt, and it doesn't look like the moles people are taught to worry about. It just sits there, slowly spreading, waiting to be noticed. If you have a scaly patch that hasn't responded to anything you've tried in the last few weeks, don't keep guessing. A proper full-body skin exam can catch this and plenty of other things people miss on their own, especially the spots on your back or legs you never actually see. Dr. Ayar and the team at Dermatology Experts see this exact scenario walk through the door regularly, patients who've been treating a "stubborn rash" for a year with over-the-counter creams, only to find out it's something that needed a biopsy from day one. If something on your skin isn't behaving the way a normal rash should, come see us at our Miami, Parkland, or Tamarac office. We'll give you a straight answer, usually the same visit.
