Tuberculids are of three types: papulonecrotic
lesions, lichen scrofulosorum and erythema induratum.
2010 revealed tuberculosis verrucous (48%) as predominant clinical type ; however, on referencing to earlier studies, Lupus vulgaris was the most common (64%), followed by tuberculosis verrucosa cutis (19%) and papulonecrotic
tuberculid (4%) .
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
 Cutaneous tuberculosis and atypical mycobacteria skin infection (AMI) present a wide range of clinical manifestations, varying from warty, nodules and papulonecrotic
lesions, to ulcerations and abscesses.
Lymphomatoid papulosis is a rare, chronic, and benign papulonodular or papulonecrotic
Other specific reactions include lupus vulgaris, scrofuloderma, lichen scrofulosorum, papulonecrotic
tuberculid, erythema induratum of Bazin and granulomatous vasculitis.
He is perhaps most remembered for his detailed analysis of papulonecrotic
Disseminated lupus vulgaris and papulonecrotic
tuberculid: case report.
tuberculid is a chronic, recurrent, symmetric eruption of necrotizing skin papules arising in crops that involve primarily the arms and the legs.
Lymphomatoid papulosis (LyP) is a chronic papulonecrotic
or papulonodular skin disease with histologic features suggestive of a malignant lymphoma.1 The term lymphomatoid papulosis originally was used by Macaulay in 1968 to describe "a self-healing rhythmical paradoxical eruption, histologically malignant but clinically benign." However, the classification system for cutaneous lymphomas has evolved rapidly, and, during consensus meetings in 2003-2004, the World Health Organization-European Organization for Research and Treatment of Cancer (WHO-EORTC) classification grouped lymphomatoid papulosis among the indolent cutaneous T-cell lymphomas.
tuberculids are skin lesions in patients with tuberculosis.
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).
