| pigment induration of the lung | A condition characterised by firmness of the lungs, and a brown colour associated with haemosiderin-pigmented macrophages in alveoli, consequent upon long-continued congestion due to heart disease. Synonym: pigment induration of the lung. (05 Mar 2000) |

| hepatogenous pigment | Bile pigment derived from the destruction of haemoglobin in the liver. (05 Mar 2000) |

| incontinence of pigment | Loss of melanin from the epidermis, and accumulation in melanophages in the upper dermis; seen in several inflammatory diseases of the skin and in incontinentia pigmenti. (05 Mar 2000) |
| formalin pigment | <chemistry> A pigment formed when acid aqueous solutions of formaldehyde act on blood-rich tissues; characterised by rotation of the plane of polarised light, withstanding extraction in aqueous and lipid solvents, being bleached in acids and hydrogen peroxide; not formed when tissue is fixed with formaldehyde buffered to pH levels above 6.

| acidophil granule | A granule that stains with an acid dye such as eosin. Synonym: oxyphil granule. (05 Mar 2000) |
| acrosomal granule | The single glycoprotein rich granule within an acrosomal vesicle, which results from the coalescence of proacrosomal granule's. (05 Mar 2000) |
| alpha granule | A granule of an alpha cell that was named as the first of several kinds or because it was acidophilic. (05 Mar 2000) |
