Sebaceous carcinoma is extremely rare in the parotid gland. Recently, we experienced a case of carcinoma with sebaceous differentiation arising from the parotid gland in patient who was diagnosed as parotid adenoma carcinoma and underwent total parotidectomy. A 73-year-old male visited our department for the evaluation of 3-month history of infra-auricular mass combined with pain. Radiologic finding showed lobulated enhancing and solid mass with calcification in the right parotid gland. Initially, total parotidectomy with supraomohyoid neck dissection was performed. Pathological findings showed capsulated whitish mass with hemorrhage and cystic degeneration. Immunohistochemically, CK7, CK5/6, p63 were positive and CEA was negative. The intra-operative frozen section diagnosis was mucoepidermoid carcinoma. The permanent diagnosis was changed to adenocarcinoma, NOS(not otherwise specified). Fourteen months later, the newly developed mass was noticed on the operation bed. The mass was clinically diagnosed as recurred adenocarcinoma. Revision parotidectomy was performed and pathological findings revealed that the tumor was newly developed sebaceous carcinoma. We report a case of carcinoma with sebaceous differentiation in parotid gland with a review of literature.

Sebaceous carcinoma is a rare malignant tumor differentiated from the adnexal epithelium of sebaceous glands and forms less than 1% of all cutaneous malignancies. We present a case of a 93-year-old woman with a rapidly growing mass on the right cheek. Initial histiopathologic finding was basal cell carcinoma. The mass was widely excised and superficial parotidectomy was performed while preserving the facial nerve branches. The resulting defect was covered with a transposition flap from the ipsilateral posterior auricular area and the donor site was closed primarily. However, histopathologic examination of the excised mass showed a poorly differentiated sebaceous carcinoma with a clear resection margin. The diagnosis of sebaceous carcinoma can be difficult to make at initial presentation. This report describes a rare case of a rapidly growing extraocular sebaceous carcinoma, which resulted in a good treatment outcome, and provides a review of relevant literature.

Sebaceous carcinoma (SC) is a rare tumor, accounting for approximately 0.7% of skin cancers. SC can be classified as ocular SC (OSC) or extraocular SC (EOSC) depending on its location. Because EOSC accompanied by metastases is rare, there is a paucity of data about EOSC accompanied by metastasis. This study presents a case of an aggressive EOSC of the scalp with lymph node metastases. The patient underwent wide local excision of the primary tumor with a 1 cm safety margin and bilateral radical lymph node dissection. However, recurrence was observed 1 month after surgery. Radiation therapy and resection were performed for the recurrent tumor. However, distant metastases to both lungs eventually occurred. Here, we describe a rare recurrent case of EOSC of the scalp with distant organ metastasis with a review of the literature.

A 4-year-old female beagle with progressive exophthalmos and which had a neoplastic mass with diameter of 1.4 cm in the left lower ocular adnexa. Histologically, the mass was composed of hyper-plastic lobules and tubular structures separated by fibrous septum. The well differentiated sebaceous gland forming various sized lobules, and infiltration of mast cells and mononuclear inflammatory cells were observed. Apical decapitation secretion of these tubular structures with basophilic materials in their lumen showed mild sebaceous gland metaplasia. Immunohistochemical studying, cell groups were positive in ${\alpha}-SMA$ and vimentin. The primary tumor was diagnosed as adenocarcinoma originated from moll gland and meibomian gland of the eyelid, and the infiltrating intraocular neoplasm was diagnosed as a malignant mixed tumor.
