Apocrine (/ ˈ æ p ə k r ɪ n /) [1] is a term used to classify the mode of secretion of exocrine glands. In apocrine secretion, secretory cells accumulate material at their apical ends, often forming blebs or "snouts", and this material then buds off from the cells, forming extracellular vesicles .
Depending on how their products are secreted, exocrine glands are categorized as merocrine, apocrine, or holocrine. [ 1 ] Merocrine – the cells of the gland excrete their substances by exocytosis into a duct; for example, pancreatic acinar cells, eccrine sweat glands [ dubious – discuss ] , salivary glands , goblet cells , intestinal glands ...
Merocrine is the most common manner of secretion. The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine). The term eccrine is specifically used to designate merocrine secretions from sweat glands (eccrine sweat glands), [1] although the term merocrine is often used interchangeably. [2] [3]
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...

Liver cell adenomatosis is also associated with becoming hepatocellular carcinoma. [11] Like hepatic adenomas, they are diagnosed with imaging and biopsies as needed. Treatment of liver cell adenomatosis is difficult due to the multiple, widespread lesions. Liver imaging should be reviewed to see if it is possible to surgically remove the ...
Polycystic liver disease (PLD) usually describes the presence of multiple cysts scattered throughout normal liver tissue. [1] PLD is commonly seen in association with autosomal-dominant polycystic kidney disease , with a prevalence of 1 in 400 to 1000, and accounts for 8–10% of all cases of end-stage renal disease .

Apocrine glands – a portion of the secreting cell's body is lost during secretion. The term Apocrine gland is often used to refer to the apocrine sweat glands, however it is thought that apocrine sweat glands may not be true apocrine glands as they may not use the apocrine method of secretion. (e.g. mammary gland, sweat gland of arm pit ...
