Sebocitas

Sebocitas is not a standard term in human anatomy or dermatology. In some Spanish-language or informal texts, sebocitas may be used as a diminutive or colloquial reference to sebocytes, the cells that compose the sebaceous glands.

Sebocytes are lipid-producing cells located in sebaceous glands, usually associated with hair follicles. They originate from stem or progenitor cells in the gland and proliferate and mature to accumulate lipid droplets. Mature sebocytes rupture with holocrine secretion, releasing sebum into the pilosebaceous duct.

Secretion and function: Sebum provides lubrication, forms the skin's barrier, and has antimicrobial properties. The composition includes triglycerides, wax esters, squalene, and free fatty acids. Production is influenced by hormones (androgens) and lifestyle; sebum production peaks during adolescence.

Clinical relevance: Excess sebum contributes to acne; sebaceous gland hyperplasia; sebaceous tumors are rare. Variations in sebum production and composition can be associated with several skin conditions and may affect skin hydration and microbiome balance.

Nomenclature and usage: If encountered, sebocitas should be clarified; standard terms are sebocytes or sebaceous glands. In scientific writing, prefer precise terminology to avoid confusion, using sebocytes to refer to the cells and sebaceous glands to refer to the glandular structures.
