Papule

Definition and stakes

Various,  Popular Science Monthly (1899)

“ About twenty-four hours later the part begins to itch again, and in a few minutes a hard, rounded, deep-red papule appears, and is quickly surrounded by an area of œdematous skin. The formication is intense, and in the affected area, while the ordinary sensations of touch are dulled, those of temperature and painful feelings are exaggerated. In two or three hours the itching diminishes and the œdema disappears, leaving a small, red papule, which itches but little. ”

“ Histology; etiology.—— Section of the papule displays an infiltration of the derma by a mass of small round granulation cells. These lie between the elements of the tissues, particularly about blood-vessels, lymphatics, and sweat-glands; towards the centre of the lesion they completely replace the normal structures. Various micro-organisms have been described in association with oriental sore. ”

Henry Weightman Stelwagon,  Essentials of Diseases of the Skin

“ Describe the papular type of dermatitis herpetiformis.
This is rarely seen as consisting purely of papular lesions, but is commonly associated with the erythematous and vesicular varieties. In a measure it resembles the papular manifestations of erythema multiforme, with a distinct disposition toward group formation. The [Pg 84] papules tend, sooner or later, to develop into vesicles, new papular outbreaks occurring from time to time; or the whole eruption changes to the vesicular or other type of the disease. It is not a common type.
