Sebaceous gland carcinoma is a rare fast growing cutaneous cancer. It is derived from the adenxal epithelium of sebaceous glands. Sebaceous carcinomas are generally divided into those occurring in periocular or extraocular locations. Ocular sebaceous carcinomas occur most commonly in upper eye lid, in the elderly with a predilection for females and Asian populations. Due to its clinical resembl...

Nevus sebaceous is a congenital, benign hamartomatous lesion, characterized by a yellowish to skin-colored, hairless, verrucous plaque on the head and neck region. In later life, a secondary tumor, either benign or malignant, can develop within nevus sebaceous. Eccrine poroma developing on nevus sebaceous is extremely rare. There are few case reports of eccrine poroma developing within nevus se...

Cystic sebaceous neoplasms have been seen only in patients with Muir-Torre syndrome (MTS) and have recently been characterized as marker lesions of MTS. Histologically, these lesions form a spectrum of tumors ranging from benign cystic adenomas to proliferative cystic sebaceous tumors. We describe 2 proliferative cystic sebaceous tumors in a 53-year-old man whose workup revealed colonic adenoca...

Sebaceous adenoma is rare lesion and frequently misdiagnosed clinically as basal cell carcinoma or squamous cell carcinoma. Sebaceous carcinoma are still rarer lesions taking origin from sebaceous glands.We report a case of sebaceous carcinoma on upper eyelid which was a diagnostic dilemma.Biopsy in this case was sent to us with clinical diagnosis of squamous cell carcinoma/Meibomian gland carc...

This paper reports a rare case of sebaceous adenoma on the right mandibular retromolar mucosa in a 73-year-old Japanese man, with a review of the English literature of sebaceous adenomas of salivary gland origin. A painless and yellowish polypoid lesion in the retromolar mucosa was histologically a relatively well-circumscribed neoplastic mass composed of well-differentiated sebaceous cells wit...

Sebaceous neoplasia comprises a spectrum ranging from benign to malignant. Proper histological identification is important for treatment, prognosis and potential association with the Muir-Torre syndrome (MTS). Our increased understanding of the significance and pathogenesis of these tumours has led to improved risk stratification, screening recommendations, and treatment of patients with an ini...

composed of cells that exhibit sebaceous differentiation; these tumors account for less than 0.1% of all salivary gland neoplasms (1, 2). The parotid gland is the most frequently involved of the salivary glands, where sebaceous differentiation is common (3). There is little information available in English literature on the radiologic features of this rare neoplasm, especially that of cystic se...

Sebaceous carcinoma is a very rare and potentially aggressive carcinoma originating from the epithelial lining of the sebaceous gland. More than 70% of all cases are in the head and neck region, especially the periorbita; therefore, they are classified into ocular and extraocular sebaceous carcinoma. The reported risk factors are advanced age, male sex, previous irradiation, and genetic predisp...
