Micrograph showing apocrine metaplasia of the breast with typical features, [4] including apical snouts with eosinophilic granules. H&E stain. Apocrine metaplasia is a reversible transformation of cells to an apocrine phenotype. It is common in the breast in the context of fibrocystic change. It is seen in women mostly over the age of 50 years.
Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland.When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
Micrograph showing apocrine metaplasia of the breast with typical features [5] H&E stain. The exact mechanism of the condition is not fully understood, though it is known to be tied to hormone level fluctuation; the condition usually subsides after menopause and is closely related to the menstrual cycle.
Micrograph showing apocrine metaplasia of the breast with typical features [3] H&E stain. Barrett's esophagus is an abnormal change in the cells of the lower esophagus, thought to be caused by damage from chronic stomach acid exposure. The following table lists some common tissues susceptible to metaplasia, and the stimuli that can cause the ...

Micrograph showing apocrine-type metaplasia of the breast with typical oncocytes. [2] H&E stain. Oncocytes (left of image), as seen in a renal oncocytoma. H&E stain. An oncocyte is an epithelial cell characterized by an excessive number of mitochondria, resulting in an abundant acidophilic, granular cytoplasm. Oncocytes can be benign or malignant.
Papillary hidradenomas that develop outside of the anogenital region are termed ecctopic papillary hidradenomas or ectopic hidradenoma papilliferums. [ 5 ] Anogenital papillary hidradenomas are regarded as tumors that form in anogenital mammary–like glands (MLAGs); MLAGs are a type of apocrine gland .
In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
