I'm sorry that your question wasn't answered in a timely manner. Can you upload a photo(s) of representative skin to our conversation? You can use the paperclip icon in the toolbar above your message box (if you can see the icon) or you can use an external app such as dropbox.com/ I can be more accurate if I can see what you're seeing. You appear to be describing eosinophilic granulomas/plaques particularly if any of the lumps have ulcerated. Eosinophilic skin disease represents an inflammatory skin disease usually associated with an underlying hypersensitivity. This skin disorder doesn't respond to antibiotics; instead, glucocorticosteroids such as prednisolone are prescribed.
Thank you for your kind accept. I appreciate it.
