We describe a case of sebaceous carcinoma (SC) in a 75-year-old man who presented with a rapidly growing nodule on the left cheek for four weeks.
A 75-year-old man presented with a crusted non-tender nodule on the left cheek that had been present for six months. The nodule showed rapid growth in the four weeks before the visit. Shave biopsy of the lesion was reported as SC.
SC is a rare but aggressive type of skin cancer that can develop from any sebaceous gland in the body. However, it mostly occurs in the eyelids. In this case, SC developed on the left cheek of the patient, which is an atypical presentation. Extraocular variant of SC has a greater potential to metastasize and has a lower survival rate compared to ocular variant. Early and accurate diagnosis followed by a wide excision surgery or Mohs micrographic surgery carries a favorable prognosis.
Early detection of extraocular variant of SC may be difficult. It is imperative for primary care providers to order a histopathology examination to investigate a rapidly growing mass in the head and neck region where there are numerous sebaceous glands.
