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.

tuberculid

a papular skin eruption usually attributed to allergy to tuberculosis.

papulonecrotic tuberculid
an eruption of crops of deep-seated papules or nodules, with central necrosis or ulceration.

Therefore, a diagnosis of lupus vulgaris was made for the left helix; both earlobes were diagnosed with discoid lupus erythematosus, and both thighs with papulonecrotic tuberculid.
Therefore, a diagnosis of papulonecrotic tuberculid of thigh lesion was made on the basis of all the clinical, pathological, and laboratory examinations.
Other specific reactions include lupus vulgaris, scrofuloderma, lichen scrofulosorum, papulonecrotic tuberculid, erythema induratum of Bazin and granulomatous vasculitis.
Papulonecrotic tuberculid is a chronic, recurrent, symmetric eruption of necrotizing skin papules arising in crops that involve primarily the arms and the legs.
Conditions in this group include: papulonecrotic tuberculid, LS, erythema induratum of Bazin, and erythema nodosum.
However, rarely antigen of mycobacterial TB has been demonstrated in papulonecrotic tuberculid, another type of more frequently seen tuberculid.
Papulonecrotic tuberculids are skin lesions in patients with tuberculosis.
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).
There are four major categories of cutaneous tuberculosis: (1) inoculation from an exogenous source (primary inoculation tuberculosis, tuberculosis verrucosa cutis); (2) endogenous cutaneous spread contiguously or by auto-inoculation (scrofuloderma, tuberculosis cutis oroficialis); (3) hematogenous spread to the skin (lupus vulgaris, acute miliary tuberculosis, and tuberculosis ulcer, gumma, or abscess); (4) tuberculids (erythema induratum [Bazin's disease], papulonecrotic tuberculids, and lichen scrofulosorum).
The grayscale values ratio of LL-37, HBD-2, and HBD-3 in the lesions of papulonecrotic tuberculids (case 4) were 4.
