BACKGROUND The Muir-Torre syndrome is a rare autosomal dominant condition and is currently considered a subtype of the more common hereditary nonpolyposis colorectal cancer syndrome, in which multiple primary malignancies occur together with sebaceous gland tumors. CASE PRESENTATION We describe a case of a 62-year-old woman with three primary colorectal tumors, genital tumor, and sebaceous ad...

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...

Sebaceous hyperplasia (SH) is a proliferative abnormality of sebaceous glands, most often seen in elderly individuals. It consists of single or multiple, asymptomatic, small yellow papules with a central depression. The face is most commonly affected, but there have been reports of SH on the chest or genitalia. A lobular array of well-differentiated mature sebaceous lobules is noted on histolog...

BACKGROUND Recent studies have demonstrated telomerase expression in ophthalmologic sebaceous carcinoma and have suggested possible diagnostic utility in distinguishing these neoplasms from sebaceous adenomas. The aim of this study was to evaluate telomerase expression via human telomerase reverse transcriptase (hTERT) immunohistochemical staining in a spectrum of sebaceous lesions of the skin....

Sebaceous adenomas of the major salivary glands are uncommon tumors. Although sebaceous differentiation within the major salivary glands is a frequent histopathologic finding (approximately 20% to 42% of parotid glands), sebaceous neoplasms of salivary gland origin are not. A number of publications review the clinical and histologic features of sebaceous neoplasms, however, these reports focus ...

The principal activity of mature sebaceous glands is producing and secreting sebum, which is a complex mixture of lipids. Sebum composition is different among species and this difference is probably due to the function that sebum has to absolve. In human sebum there are unique lipids, such as squalene and wax esters not found anywhere else in the body nor among the epidermal surface lipids. Mor...

Abstrac: Sebaceous gland carcinoma is a rare and fast-growing, potentially lethal skin malignant tumor originating from the adnexal epithelium of sebaceous glands. This more common in superior palpebral than inferior ratio 3:1 elderly with predilection for women. Because it clinically similar to chalazion or chronic inflammatory condition that can cause delays diagnosis. this rarity, we report ...

Sebaceous gland carcinoma usually arises from meibomian or Zeis glands deep within the eyelid, but it can rarely arise within the conjunctival epithelium without a deep component. We describe a woman with a history of chronic blepharoconjunctivitis unresponsive to topical medications. Examination disclosed confluent papillary hypertrophy of the upper palpebral conjunctiva and deposits of white ...

The unusual case is described of a benign parotid gland neoplasm with intermingled sebaceous and lymphoid tissue, synchronous to breast cancer. In the past, the patient had undergone a simple surgical procedure for a cystic parotid gland lesion in that same gland. Secondary neoplasms have only occasionally been reported, since there are few cases for corroborating the strong correlation between...
