As we move into the 21st century, cutaneous tuberculosis has re-emerged in areas with a high incidence of HIV infection and multi-drug resistant pulmonary tuberculosis. Mycobacterium tuberculosis, Mycobacterium bovis, and the BCG vaccine cause tuberculosis involving the skin. True cutaneous tuberculosis lesions can be acquired either exogenously or endogenously, show a wide spectrum of morphology and M. tuberculosis can be diagnosed by acid-fast bacilli (AFB) stains, culture or polymerase chain reaction (PCR). These lesions include tuberculous chancre, tuberculosis verrucosa cutis, lupus vulgaris, scrofuloderma, orificial tuberculosis, miliary tuberculosis, metastatic tuberculosis abscess and most cases of papulonecrotic tuberculid. The tuberculids, like cutaneous tuberculosis, show a wide spectrum of morphology but M. tuberculosis is not identified by AFB stains, culture or PCR. These lesions include lichen scrofulosorum, nodular tuberculid, most cases of nodular granulomatous phlebitis, most cases of erythema induratum of Bazin and some cases of papulonecrotic tuberculid. Diagnosis of cutaneous tuberculosis is challenging and requires the correlation of clinical findings with diagnostic testing; in addition to traditional AFB smears and cultures, there has been increased utilization of PCR because of its rapidity, sensitivity and specificity. Since most cases of cutaneous tuberculosis are a manifestation of systemic involvement, and the bacillary load in cutaneous tuberculosis is usually less than in pulmonary tuberculosis, treatment regimens are similar to that of tuberculosis in general. In the immunocompromised, such as an HIV infected patient with disseminated miliary tuberculosis, rapid diagnosis and prompt initiation of treatment are paramount. Unfortunately, despite even the most aggressive efforts, the prognosis in these individuals is poor when multi-drug resistant mycobacterium are present. An increased awareness of the re-emergence of cutaneous tuberculosis will allow for the proper diagnosis and management of this increasingly common skin disorder.

Impaired host immunity has been regarded as a predisposing factor in post-primary tuberculosis in adults. Patients with systemic lupus erythematosus (SLE) are usually exposed to high doses of corticosteroids and eventually develop defective cellular immunity that increases the risk for active tuberculosis. SLE-associated pulmonary tuberculosis tends to have a higher incidence of miliary, far-advanced pulmonary disease and therefore establishing the diagnosis can easily be delayed due to generalized, non-specific clinical symptoms such as fever, malaise and weight loss which are also commonly observed in lupus patients. However, cavitary tuberculosis is very rare in patients with SLE. To the best of our knowledge, fungus ball formation in the tuberculosis cavity in a patient with SLE, has not been previously reported. Thus, we present a case of SLE who was found to have a fungus ball within a preexisting tuberculosis cavity. The diagnosis was resolved by computerized tomography of the chest and was confirmed with histopathological examination.

One hundred and fifty-four patients with erythema nodosum who attended the skin clinic at Ramathibodi Hospital from January 1990 to December 2000 were evaluated retrospectively with regard to the etiology of erythema nodosum. Of 49 patients who attended the skin clinic during that time 26 returned for reevaluation. Of the 154 patients, their ages ranged from 10-72 years old; 138 were females, 16 were males. The most common cause of erythema nodosum was tuberculosis (12.3%). Upper respiratory tract infection was found in 3.9 per cent. Other causes included Behcet's disease, sytemic lupus erythematous, drugs, pregnancy, chronic myeloid leukemia, leprosy, Reiter's syndrome and inflammatory bowel disease. Of the 26 patients who returned for reevaluation, pulmonary tuberculosis was identified in only one patient who had developed erythema nodosum 16 months earlier. In conclusion, it was found that tuberculosis is still a predominant cause of erythema nodosum among Thai patients.

During the past 2 decades, tuberculosis--both pulmonary and extrapulmonary--has re-emerged as a major health problem worldwide. Nasal tuberculosis--either primary or secondary to pulmonary tuberculosis or facial lupus--is rare, but it should be considered in the differential diagnosis of nasal granulomas. We describe a case of primary nasal tuberculosis in an adult male who presented with a polypoid lesion in one nasal cavity. The diagnosis was based on histopathology and the patient's successful response to antituberculous drug treatment. Given the rising incidence of tuberculosis, it is prudent that otolaryngologists remain cognizant of this infection as a potential cause of unusual lesions in the head and neck.

We describe the rare case of a Japanese male with multifocal lupus vulgaris that preceded asymptomatic pulmonary tuberculosis and adult T-cell leukemia/lymphoma (ATL). He visited our hospital with multiple reddish plaques and erythema of 4-12 months duration. A skin biopsy revealed non-caseating epithelioid granulomas. Mycobacterium tuberculosis was detected by polymerase chain reaction (PCR)-hybridization from a skin biopsy specimen and was also isolated from a culture of the skin biopsy sample. The result of chest roentogenography was compatible with pulmonary tuberculosis. In addition, the diagnosis of ATL was based upon the presence of atypical lymphocytes with convoluted nuclei in his peripheral blood and a positive anti-ATL antibody reaction. Cases of cutaneous tuberculosis presenting with unusual clinical features may be on the increase, accompanying the spread of tuberculosis in immunosuppressed patients, including those with ATL and acquired immunodeficiency syndrome (AIDS).

Although there has been a steady decline in the incidence of tuberculosis in recent years, it persists in some regions, and where AIDS is especially prevalent, the number of new cases has been increasing. Thus, cutaneous tuberculosis has re-emerged in areas with a high incidence of HIV infection and multidrug-resistant pulmonary tuberculosis. Lupus vulgaris has been and remains the most common form of cutaneous tuberculosis. Cutaneous manifestations of disseminated tuberculosis are unusual, being seen in less than 0.5% of cases. Scrofuloderma, tuberculosis verrucosa cutis and lupus vulgaris comprise most cutaneous tuberculosis cases. Bacillus Calmette-Guerin (BCG) is derived from an attenuated strain of Mycobacterium bovis and is employed beneficially as a relatively safe vaccination in Poland and other countries in which the prevalence of tuberculosis is high. However, BCG vaccination may produce complications, including disseminated BCG and lupus vulgaris, the latter seen in one of our two patients in whom lupus vulgaris at the inoculation site followed a second vaccination with BCG 12 years after the initial one. A similar phenomenon has been described after immunotherapy with BCG vaccination. Re-infection (secondary) inoculation cutaneous tuberculosis may also occur as a result of BCG vaccination, producing either lupus vulgaris or tuberculosis verrucosa cutis, probably depending upon the patient's degree of cell-mediated immunity. However, most lupus vulgaris cases are not associated with vaccination with BCG, as occurred in our first patient. For those who do develop lupus vulgaris, it can be persistent for a long period, in some cases for many decades. In the second patient we describe a lengthy duration and cutaneous reactivation at distant sites after more than 40 years.

Between April 1975 and March 2005, 4,436 cases of histologically proven glomerulonephritis (GN) were diagnosed by the same team at the Kidney Unit of Charles Nicolle Hospital in Tunis. Respectively 1,510, 1,419 and 1,509 cases were diagnosed in 1975-1985, 1985-1995, and 1995-2005. We compared trends in the incidence rates of the different types of GN and those of Tunisian indicators of health, social and economic status. The following differences were found between 1975-1985 and 1995-2005:--As a proportion of all cases of GN, the frequency of amyloidosis fell from 12,6 % to 6,5 % (p < 0,0001). The 444 cases of amyloidosis observed during the study period were of type AA in 87 % of cases, and were related to chronic infectious diseases in 239 cases (54 %; pulmonary tuberculosis in 114 cases). The frequency of tuberculosis-associated amyloidosis fell during the study period, in parallel with the reduction in the incidence of tuberculosis in the Tunisian population (48,7 cases/100,000 inhabitants in 1983 to 20,17 in 2004). Lupus nephritis accounted for 7.7 % of all cases of GN diagnosed in 1975-1985, compared to 13 % in 1995-2005 (p < 0,00001). Increased exposure to sunlight and use of cosmetics could be involved in this increase.--The incidence of both proliferative endocapillary and membranoproliferative GN (as a proportion of all cases of GN) fell between 1975-1985 and 1995-2005, from 15,9 % and 21,6 % to 6,9 % and 7,7 %, respectively (p < 0,0001). This matched a drop in the incidence of acute rheumatic fever in the Tunisian population, from 7,26/100,000 inhabitants in 1984 to 0,83 in 2004, probably as a result of public health measures and widespread use of antibiotics. The incidence of membranous GN increased from 11,1 to 17,7 % in adults (p < 0,001) whereas it fell from 10,1 to 4,6 % in children (p < 0,01), possibly as a result of a nationwide HBV vaccination program launched in 1995. The incidence of IgA nephropathy increased from 0,9 to 12,9 % in adults (p < 0,0001) and from 0,3 % to 18,4 % in children, but remained relatively stable in elderly adults. This study, conducted in a single center, by the same team, and using the same renal biopsy practices, confirms that the control of infectious diseases in Tunisia has led to a substantial regression of proliferative endocapillary and membranoproliferative GN and renal amyloidosis. Environmental factors, such as the adoption of western lifestyles, could explain the increase in lupus and IgA nephropathies.

We describe an unusual case of elderly onset systemic lupus erythematosus (SLE) that presented with disseminated intravascular coagulation (DIC). An 86-year-old man who complained of general malaise was admitted for evaluation and treatment of thrombocytopenia. He was diagnosed as having SLE and DIC based on the criteria of the American College of Rheumatology for SLE (renal involvement, hematological abnormalities, and positivity for antinuclear antibody and lupus anticoagulant) and the criteria for DIC presented by the subcommittee on DIC of the ISTH (a large increase of fibrin degradation products [3 points] and a platelet count <50 x 10(3)/ml [2 points], resulting in a score of 5; a score > or =5 is compatible with DIC). The patient was treated with corticosteroid therapy (30 mg/day); the DIC and SLE remitted, and his renal function improved, but he developed pulmonary tuberculosis. Timely diagnosis, appropriate treatment, and an awareness of the potential for serious infections are of utmost importance when dealing with patients with elderly onset SLE.

Lupus vulgaris is the most frequent manifestation of cutaneous tuberculosis, but in Europe it is limited to isolated cases. Mainly immunocompetent individuals are affected by this result of an endogenous reinfection on a lymphogenous-less frequently hematogenous-pathway. Lupus vulgaris has been observed to develop in more than 50% of all patients who already suffer from other manifestations of tuberculosis. The development of a squamous cell carcinoma in the lupus vulgaris is a rare complication; therefore, lupus vulgaris is deemed a facultative precancerosis.A 68-year-old female Serbo-Croatian patient presented with an extensive ulcerative nose and facial tumor. Her anamnesis included a squamous cell carcinoma of the nose that had been excised alio loco 3 years before. Further examinations revealed enlarged cervical lymphoma on both sides, and pulmonary metastases were also suspected. The tumor biopsy revealed a necrotic, granulomatous inflammation. No acid-fast rods were seen on Ziehl-Neelsen stain. The tuberculous origin of this ulcerative skin tumor-the lupus vulgaris-as an endogenous reinfection of pulmonary tuberculosis manifestation was confirmed by the detection of Mycobacterium tuberculosis DNA in polymerase chain reaction and the growth of Mycobacterium tuberculosis colonies in the bacterial culture (skin biopsy and bronchial secretion). The skin tumor as well as the pulmonary manifestation were successfully treated with combined tuberculostatic therapy and showed a dramatic response within 3 months.
