Xanthogranulomas are the most common form of non-Langerhans cell histiocytosis. Both adult and childhood forms have been described. Adult cutaneous forms can present as solitary or multiple yellowish, orange-red or tan-hued papules. Herein, we present the case of a 28-year-old Chinese man with a skin-coloured nodule on his left nasal ala that persisted for several months. While initial impression was that of a fibrous papule of the nose, the results of an excision biopsy showed histological features corresponding to xanthogranuloma. This case demonstrates the condition's myriad of dermatological presentations, and adds to the differential diagnoses of a cutaneous lesion found in the head and neck region.
