Facial solitary morphea profunda presenting with painful trigeminal neuropathy: A case report.

BACKGROUND: Localized facial scleroderma usually presents as frontal linear morphea or progressive hemifacial atrophy. Only isolated cases of trigeminal painful neuropathy have been described. CASE REPORT: A 43-year-old woman developed an oval lesion on the right cheek. After 1 year, she noticed constant "pulling" pain and episodes of lancinating pain, both spontaneous and triggered by chewing and cold drinks. She was diagnosed with solitary morphea profunda and CT scan, ultrasonography, cranial MRI and biopsy were completed. Methylprednisolone (1 gr/day for 3 days) was prescribed. For pain, gabapentin, oxcarbazepine, amitryptiline, pregabalin and eslicarbacepine were all ineffective. A capsaicin patch was placed with prolonged benefit. Later on, the pain slightly worsened; occipital blockade was effective and methotrexate was recommended. CONCLUSION: This is the first case of solitary morphea profunda associated with painful trigeminal neuropathy. Treatment should include immunosuppressants and treatment of neuropathic pain, in which local therapies seem particularly beneficial.
