Vanishing skin rash of syringomyelia 「脊髄空洞症に見られた消える皮疹」
Case:28 y/o female
3weeks before coming into my clinic, she felt something pulling and a kind of numbness as well on her right lateral chest. Because it was not severe, she was just watching the symptoms. 2weeks after the initial sign began, not only the symptoms remained but also pain was coming out, she saw an orthopedist, but nothing was able to find out. The same morning that I saw her at my clinic, a skin rash had appeared on her right lateral chest and was located the Th2 area of the dermatome. She was seen in a dermatologist, but the doctor told her nothing, but herpes zoster was excluded. She wanted to know what happened to her, so I examined her in detail and ordered spinal MRI.
On the MRI findings, syringomyelia was on the level of Th2. I recognized that symptoms of abnormal feeling on her right lateral chest, skin rash as well were exceedingly early symptoms of syringomyelia. The rash had vanished in a week. I have not experienced before like this phenomenon. There were no articles I can find out if searching on the PubMed. So, if you see the patient at the chronic phase, you miss this rash obviously.
I am incredibly happy to let you know these rare findings together.
文献を見ると、プレクリニカルRA、超早期関節リウマチなどのkey wordが引っかかってくる。最近では、発症から3ヵ月以内のものをvery early RAとする報告もある。この患者は再診していないのでまだ疑診の段階だが、彼女が来院したら膠原病リウマチ科の専門医にreferしたいと考えている。私もそろそろ後期高齢者になるが、地域医療には終わりがないと悟らされる毎日だ。
