The case of a 75-year-old Caucasian woman with a trigeminal trophic syndrome (TTS) is presented and discussed. TTS of the ala nasi subsequent to a herpes zoster infection has not been described previously. We provide a review of the literature with insights into the pathogenesis and current therapeutic strategies.
Keywords Trigeminal trophic syndrome · Ala nasi lesion · Herpes zoster infection · ReviewCase report A 75-year-old Caucasian woman was referred to our department with a right ala nasi lesion (Fig. 1). She had a history of breast carcinoma, which had been treated with surgery and radio-chemotherapy. Three years ago, herpes zoster affected the second division of the right trigeminal nerve. Subsequently, the patient developed postherpetic neuralgia, which was treated with carbamazepine. The initial anterior rhinoscopy showed a small mucosal fissure of the right nasal ala. Treatment consisted of local application of polymyxin-B ointment. Three months later, the patient returned with a distinct lesion, which expanded within weeks and was associated with recurrent bleeding. The following physical examination revealed a crescent lesion of about 2 cm in length with a concomitant loss of a significant portion of the right ala nasi and a complete anesthesia of the maxillary dermatome. The patient complained about numbness, paresthesia and the psychosocial impact of the lesion. We ruled out a malignant lesion with biopsies, and computed tomography was performed (Fig. 2). Two biopsies from the remaining ala and the lateral nasal margin confirmed the lack of malignancy. Histopathologically, the hyperkeratotic epidermis did not have any irregularities or signs of malignant transformation. Considering the patient's history of herpes zoster in the same right maxillary dermatome and the persistence of anesthesia, we assumed a trophic malfunction, e.g., trigeminal trophic syndrome (TTS). To our knowledge, TTS of the ala nasi has not been previously reported subsequent to a herpes zoster infection. After a thorough assessment and review of the literature, we decided to Eur Arch Otorhinolaryngol (2003) 260 : 86-90
