"We demonstrate for the first time ever how the sebaceous glands
that contribute to the natural moisture of the skin are formed and how they are maintained throughout life by stem cells.
Normal sebaceous glands
can sometimes become entrapped within BCC, squamous cell carcinoma, or other cutaneous epithelial neoplasms; it is important not to mistake these for true sebaceous differentiation within a tumor.
Basal cell carcinoma (BCC) is the most frequent malignant eyelid tumor followed by squamous cell carcinoma (SCC), sebaceous gland
carcinoma and malignant melanoma.11
The presence of Fordyce granules in the area of involvement suggests that the tumor may have arisen from the malignant transformation of these ectopic sebaceous glands
DHEAS, regulator of sebaceous gland
activity through its conversion to DHT and Testosterone in sebaceous gland
by potent enzymes.
Biopsy was taken from the bottom of the lesion, and histological examination revealed a large number of mature sebaceous glands
, slight papillomatosis with hyperkeratosis, and acanthosis of the epidermis [Figure 1]b.
Underlying wall was composed of sebaceous glands
, adipose tissue, salivary gland tissue, and hyaline cartilage (Figures 3 and 4).
This keeps sebaceous glands
healthy and secretion of sebum under control.
Lead acetate applications abnormal differentiation of epidermal keratinocytes, the hair follicles and sebaceous glands
has been shown to increase in apoptotic cells.
"Since Malassezia is an obligatory lipophilic fungus, differential Malassezia abundance might be due to the full activation of sebaceous glands
during puberty," they theorized.
An advantage of both these methods is the removal of mites not only from the surface of the skin but also directly from the sebaceous glands
, as well as evaluating large affected areas.
