I suspect that her nose is hyperkeratotic but I'd like to take a look at it. Can you upload a photo(s) of her nose to our conversation? You can use the paperclip icon in the toolbar above your message box (if you can see that icon) or you can use an external app such as

Thank you! She suffers from a severe hyperkeratosis of her nose.

This is an idiopathic (unknown cause) condition characterized by the excessive formation of nasal keratin. Thickened, hard, dry keratin accumulates on the nasal planum - mostly on the dorsum of the nose as is the case here. Secondary erosions, ulcers and fissures may be present and represent an autoimmune skin disease (the immune system is attacking my patient’s own tissues). Autoimmune skin disease is identified only by biopsy.

The intensity of therapy depends on the severity of the lesions. The nasolacrimal ducts should be flushed because blockage of those ducts may present a contributing factor. For mild, asymptomatic cases, affected areas should be hydrated with a warm water soak. A softening agent, then, should be applied every 24 hours until excessive keratin has been removed (~7-10 days). Treatment should be continued on an as-needed basis for control. Effective softening agents include the following: petroleum jelly, A&D ointment, ichthammol ointment, salicylic acid/sodium lactate/urea gel, and tretinoin gel. (The last three are available from her vet.) For fissured lesions, combination antibiotic/glucocorticoid ointment (Panalog, e.g.) may be applied to lesions every 8-12 hours until healed. Horny growths should be trimmed away before hydration and softening therapy are begun.The prognosis is good. Although it's incurable, this is a cosmetic disease that usually can be managed symptomatically. Please respond with further questions or concerns if you wish.
