چکیده
Cutaneous tuberculosis (CT) can be classified as true cutaneous tuberculosis and tuberculids which is regarded as a hypersensitivity reaction to Mycobacterium 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. The following is a case report of a young female patient with PNT.

BACKGROUND Papulonecrotic tuberculid (PNT) is said to be a hypersensitivity reaction to M. tuberculosis. Some reports indicate that organisms are demonstrable by polymerase chain reaction (PCR). METHODS We describe 12 patients with PNT over 6 years. We reviewed the histopathologic features, clinical data and follow-up. PCR for M. tuberculosis DNA was done in all cases. RESULTS There were 7 ...
متن کاملPerforating granuloma annulare mimicking papulonecrotic tuberculid*
A case is reported of a patient presenting lymph node tuberculosis and cutaneous lesions resembling papulonecrotic tuberculid, but histologically compatible with perforating granuloma annulare and which responded satisfactorily to antituberculous therapy. This is probably one of the first reports of the association of perforating granuloma annulare and tuberculosis, and it is important therefor...
متن کاملDetection of mycobacterial DNA in papulonecrotic tuberculid lesions by polymerase chain reaction.
Tuberculids are a heterogeneous group of cutaneous lesions. Recent discoveries of M. Tuberculosis DNA in these lesions by PCR suggest that M. tuberculosis could play a role in their pathogenesis. The aim of this study was to demonstrate the presence of M. tuberculosis DNA by polymerase chain reaction in papulonecrotic tuberculid lesions. Skin biopsy specimens from ten patients with papulonecrot...

Papulonecrotic tuberculid is a rare, chronic, recurrent and symmetric eruption of necrotizing skin papules arising in crops, involving primarily the limbs. It occurs in less than 5% of active tuberculosis. Typically bacilli are not detected in any of the cutaneous lesions. Extracutaneous tuberculosis primary focus is only detected in 30-40% of the cases, being the lymph nodes the most common lo...
متن کاملPapulonecrotic tuberculid--a rare skin manifestation in a patient with pulmonary tuberculosis.
Papulonecrotic tuberculid (PNT), a cutaneous manifestation of tuberculosis, is rare even in areas endemic for tuberculosis such as Taiwan. Concomitant pulmonary tuberculosis is uncommon in patients with PNT. We describe a patient with rare skin manifestations and simultaneous pulmonary tuberculosis. This 48-year-old woman had suffered from productive cough for 4 months, and pea-sized papules wi...
