sebaceous carcinoma is a relatively rare cutaneous tumor that is most commonly derived from the sebaceous glands located in periorbital area. the extraocular occurrence of this tumor is very rare. we report a case of an 85 years old woman who presented with a slowly enlarging mass on the right temporal region. histological examination of the lesion revealed a malignant sebaceous carcinoma occur...

Introduction: This is to report a rare case of sebaceous carcinoma of inner cantus of the eye in relation with rare skin lesions of epidermodysplasia verruciformis. Epidermodysplasia verruciformis is a rare skin disease which is caused by human papilloma virus. Sebaceous carcinoma is a rare entity which is derived from sebaceous glands and to our best knowledge this is for the first time that w...

Extraocular sebaceous carcinoma is a relatively rare skin appendage carcinoma [1]. Although ocular sebaceous carcinoma is thought to arise from the Meibomian glands and glands of Zeis, there is no evidence that extraocular sebaceous carcinoma arises from pre-existing sebaceous glands [2]. Most sebaceous carcinomas are invasive [1], however, only a few cases of sebaceous carcinoma associated wit...

Sebaceous carcinoma is a malign tumor of sebaceous glands and it is usually found on the eyelid. However, sebaceous carcinoma can arise anywhere in the body where sebaceous glands exist. Extraocular localization of the sebaceous carcinoma is rare and accounts for 25% of all cases. Sebaceous carcinoma is more common in women between the ages of 60 and 70. Moreover, Asian population is more likel...

      Abstract: development of squamous cell carcinoma from sebaceous cyst is uncommon.in this report , we report a77- old female patient who has had a sebaceous cyst for 20 years. The cyst started to grow during the last year. The patient underwent an operation for excision biopsy and The diagnosis was squamous cell carcinoma.

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...

IMPORTANCE The molecular-genetic alterations contributing to the pathogenesis of sebaceous carcinoma and sebaceous adenoma remain poorly understood. Given that sebaceous carcinoma is associated with substantial morbidity and mortality, there is a critical need to delineate the pathways driving sebaceous carcinoma and candidate molecules for targeted therapy. OBJECTIVE To describe differential...

BACKGROUND Ocular sebaceous carcinoma is an uncommon, aggressive ocular neoplasm with potential for regional and distant metastasis. CASE PRESENTATION A 77-year-old woman was found to have a solitary pulmonary lesion 6 years after the initial treatment of sebaceous carcinoma of the eyelid. Video-assisted lung wedge resection of an undetermined pulmonary nodule was carried out successfully. Mi...

Apocrine skin carcinoma is an aggressive cutaneous tumour. We report a case of apocrine carcinoma developing in a naevus sebaceous of scalp in a 45 years old male. Malignant transformation of Naevus sebaceous is a rare complication usually found in elderly patients. Most of these tumours are basal cell carcinoma or squamous cell carcinoma. Only few cases of apocrine carcinoma on naevus sebaceou...

The classification of benign sebaceous neoplasms has been challenged both by the assertion that sebaceous adenomas are really carcinomas and by difficulties in drawing the boundaries between sebaceomas and other lesions. We performed a clinicopathologic study of 30 cases of basaloid neoplasms with sebaceous differentiation, excluding cases of definite sebaceous carcinoma with severe nuclear aty...
