Abstract
Papulonecrotic tuberculid (PNT) is an uncommon form of id eruption that occur in association with tuberculosis infections, in patients with a high degree of immunity and allergic sensitivity to mycobacterial organisms. It commonly presents as recurrent crops of papulonecrotic lesions which crust or ulcerate and heals with atrophic varioliform scars over a period of time. The differential diagnosis is wide and varying. Tuberculin test is usually strongly positive. Histology shows tuberculoid histology with endarteritis and thrombosis of dermal blood vessels. One of the hallmarks of PNT is its prompt response to antituberculous therapy. The purpose of this article is to increase awareness of this condition among dermatologists.

Abstract
Cutaneous tuberculosis can be classified as true cutaneous tuberculosis and tuberculids which is regarded as a hypersensitivity reaction to M. tuberculosis in patients with a high degree of tuberculin sensitivity. Papulonecrotic tuberculid (PNT) is a form of tuberculid. It is an uncommon manifestation even in areas with high prevalence of tuberculosis. We report a case of 35-year-old man who presented with necrotizing papules in symmetrical fashion over the trunk and extremities for last one year along with a discharging sinus in right axilla for last two months. Papulonecrotic tuberculid (PNT) with scrofuloderma were suspected on clinical examination. Mantoux test was strongly positive with 20x20mm. He was treated successfully with ATT without any further appearance of new lesions.

Abstract
Although papulonecrotic tuberculid is an uncommon cutaneous manifestation of tuberculosis (TB) associated with Mycobacterium tuberculosis infection, the simultaneous occurrence of papulonecrotic tuberculid and erythema induratum is even rarer. Papulonecrotic tuberculid occurs predominantly in young adults and is characterized by eruptions of necrotizing papules that heal with varioliform scars. Histopathologic findings include wedge-shaped necrosis of the dermis, poorly formed granulomatous infiltration, and vasculitis. Stainings and culture for acid-fast bacilli from skin biopsies are usually negative for M. tuberculosis, although the eruptions resolve with antitubercular therapy. Few patients with papulonecrotic tuberculid, especially with concurrent occurrence of erythema induratum, have been reported in the English literature. Here we report a case of a 12-year-old girl with simultaneous occurrence of papulonecrotic tuberculid and erythema induratum accompanying pulmonary TB.

Abstract
The tuberculids are hypersensitivity reactions to Mycobacterium tuberculosis (MTB) and include papulonecrotic tuberculid (PNT), lichen scrofulosorum, erythema induratum of Bazin (EIB), and phlebitic tuberculid. Papulonecrotic tuberculid displays papulonecrotic lesions mostly on the extensor surfaces of the limbs. Histopathology shows necrosis, granulomatous inflammation (GI), and occasionally vasculitis, usually in the superficial dermis. Erythema induratum of Bazin shows nodulo-ulcerative lesions on the posterior aspect of the legs. Histopathology reveals a septolobular panniculitis, necrosis, GI, and vasculitis. The Mantoux test is strongly positive and associated tuberculosis (TB) may be present in both conditions. MTB cannot be demonstrated with a Ziehl-Neelsen (ZN) stain or cultured. The polymerase chain reaction has demonstrated MTB DNA in PNT (50%) and EIB (25%). The tuberculids respond to full anti-TB treatment. We document four patients with nodules on the legs in whom the pathologic changes were situated in the deep dermis and adjacent subcutaneous fat. Nodular tuberculid (NT) is regarded as a suitable term for these lesions. All patients were female. Their ages were 19 months, 12 years, 17 years, and 5 years. All patients presented with nodules on the limbs. These nodules were approximately 1 cm in diameter, dull red or bluish-red, and nontender. Ulceration was not present. The number of nodules varied from a few to many. The Mantoux test was strongly positive in all the patients. Associated pulmonary TB was present in two patients. Histopathology showed GI (n = 4), vasculitis (n = 2), and coagulative necrosis (n = 2). A ZN stain was negative in each case. All patients received anti-TB treatment for 6 months [rifampicin (n = 4), isoniazid (n = 4), pyrazinamide (n = 4), and ethambutol (n = 2)]. At 12 months follow-up, skin and pulmonary lesions had resolved in all. Nodular tuberculid should be distinguished from arthropod bites and papular urticaria, dermal erythema multiforme, evolving vasculitis, evolving folliculitis, and erythema nodosum. Histopathologically NT should be distinguished from other causes of granulomatous vasculitis and GI with or without necrosis. In children with nodules on the limbs unresponsive to routine treatment, skin biopsy should be done to exclude NT. Nodular tuberculid represents a hybrid between PNT and EIB with characteristic clinicopathologic features and should be included in the classification of cutaneous TB.

Abstract
We describe a patient in whom two tuberculids, lichen scrofulosorum, and erythema induratum occurred simultaneously. The clinical and histopathologic features were characteristic and a Mantoux test showed a positive reaction. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for mycobacteria in the skin lesions was negative, but her lesions responded rapidly to antituberculous chemotherapy.

Abstract
Erythema induratum of Bazin is a tuberculid that is strongly associated with tuberculosis. Clinically, erythema induratum of Bazin show recurrent tender subcutaneous nodules that occur mainly on the calves of women with tuberculin hypersensitivity. Previous studies have not documented the histopathologic spectrum of erythema induratum of Bazin in detail. We identified two major histopathologic groups in 19 of 20 skin biopsies obtained from 20 patients with well-documented erythema induratum of Bazin. Six cases (group I) showed focal septolobular panniculitis in close association with a single muscular artery or small vessel with primary neutrophilic vasculitis. Thirteen cases (group II) revealed diffuse septolobular panniculitis with primary neutrophilic vasculitis of either large or smaller vessels. Both groups showed varying combinations and degrees of acute and chronic inflammation, coagulative and caseation-like necrosis, and granulomatous inflammation. Poorly developed granulomas predominated, but mixed, palisading, and lipophagic granulomas also occurred. Inflammation and necrosis were more extensive in group II. Erythema induratum of Bazin may show predominantly acute suppurative or granulomatous panniculitis. Immunostaining showed S100+ antigen-presenting cells, macrophages, and T-lymphocytes. B-lymphocytes were rare. The presence of primary vasculitis and granulomas suggests that types III and IV hypersensitivity reactions play a role in the pathogenesis or erythema induratum of Bazin. The latter remains a clinicopathologic diagnosis, but awareness of the heterogeneous histopathologic spectrum of EIB will ensure a timely diagnosis and institution of antituberculous treatment.

Abstract
BACKGROUND There has been a long controversy about the tuberculous cause of erythema induratum, a chronic form of nodular vasculitis. METHOD We investigated clinical, histopathologic, and immunohistochemical features of patients with erythema induratum who showed positive tuberculin hypersensitivity reactions or had associated active tuberculosis. RESULTS The ages of the 32 patients (M 7: W 25) ranged from 13 to 66 years (mean 36.6 years). All patients displayed recurrent crops of tender, painful, violaceous nodules or plaques. Most lesions presented on the legs, but they also occurred on thighs, feet, buttocks, and forearms. The skin lesions evolved for several weeks and healed with scarring and residual pigmentation. Twenty-two patients were treated with isoniazid alone and the remaining 10 patients received combinations of antituberculous drugs. Relapses were encountered in four patients who received isoniazid alone or stopped the medication against medical advice. In most biopsies, histologic examination revealed lobular or septolobular panniculitis with varying combinations of granulomatous inflammation, primary vasculitis, and necrosis. Immunohistochemical labeling revealed a preponderance of T lymphocytes, monocyte-macrophages, and Langerhans' cells, indicative of a type IV hypersensitivity reaction. CONCLUSION Erythema induratum of Bazin has distinct clinical, histopathologic, and immunohistochemical features. Erythema induratum of Bazin should be considered as a separate entity of nodular vasculitis caused by latent foci of tuberculous infection.

Abstract
Papulonecrotic tuberculid (PNT), a form of cutaneous tuberculosis (TB), is uncommon in children. We identified eight children (six girls and two boys) with PNT. Their ages ranged from 19 to 139 months (median 47.5 months, mean:64.75 months). Skin lesions had been present for 2-24 weeks (median: 4 weeks) before diagnosis. All patients displayed scattered papulo- and/or pustulonecrotic lesions on the limbs, and the ears were involved in six patients. Lesions healed with varioliform scars. Associated pulmonary TB was present in seven patients. Additional clinical findings included fever (n = 4), hepatomegaly (n = 4), lymphadenopathy (n = 3), phlyctenular conjunctivitis (n = 3), and splenomegaly (n = 2). Histology of eight biopsies showed ulceration (n = 6), dermal necrosis (n = 6) (follicle-centered in two), granulomatous inflammation (n = 6) (palisading granuloma-like in three), superficial and deep infiltrate of lymphocytes (n = 7), erythrocyte extravasation (n = 7), and subepidermal edema (n = 3). Vasculitis was not a feature. A Ziehl-Neelsen stain was negative in all. Glycosaminoglycans were not increased. Immunohistochemistry found a predominance of T lymphocytes, macrophages, a few antigen-presenting cells, and no B lymphocytes, consistent with a type IV hypersensitivity reaction. Polymerase chain reaction (PCR) performed on deparaffinized tissue identified M. tuberculosis DNA in one biopsy. All patients received combination anti-TB treatment for 6 months. Six patients were compliant and were followed up for 6-30 months. Skin lesions and pulmonary TB healed in all. PNT in children resembles the adult form, but phlyctenular conjunctivitis and associated TB are more common, scrofuloderma and concomitant erythema induratum of Bazin are unusual, and vasculitis is not found. In cases where M. tuberculosis DNA can be confirmed with PCR, papulonecrotic TB is perhaps the more appropriate nomenclature.
