The case reported here is an 18 year old male. He complained of a painless lump located on the left cheek over the anterior surface of masseter muscle for last 2 years. An early diagnosis of sebaceous cyst was made. Excision was performed and histopathological findings revealed pilomatrixoma. Pilomatrixoma is an uncommon, harmless, skin lesion derived from hair matrix cells. It is composed of an epithelial component of the most proximal portion of hair follicle. It is most often diagnosed in young children but may also affect adults. Single skin coloured or purplish lesions arise on the head and neck, but they may occur at any site. The key to diagnosis is identification of darkly stained 'basophilic cells' and 'shadow cells'. Calcium deposits are found in most of the lesions. Complete surgical excision is the treatment with rare chances of complications.
