Extraocular sebaceous carcinoma of neck: A case Report

Context: Sebaceous cell carcinoma is a malignant neoplasm, rarely recognized in extra ocular sites. This neoplasm is aggressive in 29% of patients, lymph node and visceral metastasis are common. Its prognosis depends on early diagnosis of lesion. Clinical & Diagnostic features: An 49 year old female had slow growing nonulcerative subcutaneous nodule on the nape of neck of 9 months duration. On FNAC cytological findings favoured a benign skin adenexal tumor with focal nuclear atypia. On histological examination it was diagnosed as a poorly differentiated sebaceous carcinoma. Conclusion: Extra ocular sebaceous carcinoma is a rare neoplasm. It is difficult to diagnose as it has diverse clinical presentations, histologic patterns and complicated nomenclature. We will discuss the incidence, clinical, and histological findings along with the prognosis of this aggressive neoplasm.
