A 40-year-old woman presented with an asymptomatic skin coloured lesion on the nose for the past 2 years. On examination, a solitary dome-shaped, firm, and non-tender skin coloured papule on the nose was noted [Figure 1]. Clinical differential diagnoses included fibrous papule of the nose and solitary trichoepithelioma. Biopsy showed a well-circumscribed spindle cell tumour bundled in the form of fascicles, showing nuclear palisading in places. Small clefts and a thin fibrous capsule were seen. A final diagnosis of palisaded and encapsulated neuroma was given [Figures 2a and b]. This case underscores the need to consider this uncommon entity in the differential diagnosis of a solitary facial papule.
