papulonecrotic tuberculid

tuberculid

 [too-ber´ku-lid]
any of a group of conditions involving recurrent eruptions of the skin, usually characterized by spontaneous involution; it includes erythema induratum, lichen scrofulosorum, and papulonecrotic tuberculid, and sometimes also lupus miliaris disseminatus faciei.
papulonecrotic tuberculid a grouped symmetric eruption of symptomless papules appearing in successive crops and healing spontaneously with superficially depressed scars, which occur chiefly on the extensor surface of the extremities in infants, children, and young adults.

pap·u·lo·ne·crot·ic tu·ber·cu·lid

dusky-red papules followed by crusting and ulceration with nongranulomatous vascular changes primarily on the extremities and predominantly in young adults with a deep focus of tuberculosis or with a history of preceding infection.

papulonecrotic tuberculid

A distinct tuberculosis-associated disorder characterised as a chronic, recurrent and symmetric eruption of necrotising skin papules arising in crops, primarily on the extremities, which usually heal with varioliform scarring. Papulonecrotic tuberculid is thought to represent a hypersensitivity reaction to tuberculosis antigens released from a distant focus of infection. Most patients react briskly to the Mantoux skin test (purified protein derivative, PPD) and may have other evidence of current or past tuberculosis.

(pap'yū-lō-nĕ-krot'ik tū-bĕr'kyū-lid)
Dusky-red papules followed by crusting and ulceration primarily on the limbs and predominantly in young adults with a deep focus of tuberculosis or with a history of preceding infection.

In the present study, lupus vulgaris was the most common variant of cutaneous TB followed by tuberculosis verrucosa cutis, scrofuloderma and papulonecrotic tuberculids (Table 3).
He is perhaps most remembered for his detailed analysis of papulonecrotic tuberculides.
The grayscale values ratio of LL-37, HBD-2, and HBD-3 in the lesions of papulonecrotic tuberculids (case 4) were 4.11, 1.39, and 1.35, respectively; the grayscale value ratios of LL-37, HBD-2, and HBD-3 in the lesions of erythema induratum (case 5) were 5.12, 1.15, and 1.66, respectively; which showed the expressions of LL-37, HBD-2, and HBD-3 in tuberculids had an increasing trend compared with that of normal skin [Figure 4].{Figure 4}
