Pulmonary tuberculosis presenting as tubercular lupus

Pulmonary tuberculosis can be associated with skin manifestations. We report a case in which cutaneous tuberculous lesions were associated with asymptomatic pulmonary tuberculosis. A 15-year old woman had four cutaneous tumoral lesions on her face back, a few of which had evolved over a period of several years. They were asymptomatic nodular lesions, with rounded bumps, with, in places, cheloidal features. The biopsy specimen revealed non-caseating epithelioid granulomas with giant cells and the culture grew Mycobacterium tuberculosis. Cavitating pulmonary tuberculosis was then revealed by CT scan and acid-fast bacilli were isolated in her sputum. The skin lesions disappeared with anti-tuberculosis therapy. Cutaneous manifestations of tuberculosis are rare, polymorphous, and can be associated with an underlying visceral infection. Lupus vulgaris is the most common cutaneous manifestation of tuberculosis in industrialised countries, but nevertheless it remains rare and it is a very unusual presenting feature of underlying pulmonary tuberculosis.     

A case of miliary tuberculosis with cutaneous lesion

Miliary tuberculosis associated with cutaneous lesion has been rarely reported. We report a case of miliary tuberculosis in whom the cutaneous lesion was confirmed as tuberculosis by skin biopsy and bacterial examination. A 46-year-old man was admitted because of cough, fever, sore throat and abnormal shadow on the chest X-ray. Physical examination revealed an emaciated man with two ulcerous lesions overlying yellowed crust on the chest wall and fine crackles on the left side of the lung. Laboratory workup revealed a white blood cell count of 10,000 with 15% lymphocytes and positive CRP. Chest X-ray film showed the infiltration with cavity formation in left upper lung field and nodular dissemination. His tuberculin reaction was negative on admission. Sputum, urine and secrete from cutaneous lesion were positive for the acid-fast bacilli and the culture grew Mycobacterium tuberculosis. Examination of the skin biopsy specimen and bone marrow aspiration showed Langhans giant cells around necrotic lesion; therefore the diagnosis of miliary tuberculosis was made. After an initiation of antituberculosis therapy with combined regimen composed of streptomycin (SM), isoniazid (INH), ethambutol (EB) and rifampicin (RFP), this patient improved significantly. Although the case report of miliary tuberculosis tends to increase recently, the report of cutaneous lesion is relatively rare in association with miliary tuberculosis. We discussed this subject with reference to the literatures.     

Cutaneous miliary tuberculosis in a renal transplant patient: a case report and literature review

The incidence of tuberculosis in renal transplant recipients is higher than in the general population. However, the incidence of cutaneous miliary tuberculosis in these patients is very rare. We report a 56-year-old renal transplant Thai man admitted to the hospital with prolong fever, dry cough and multiple small erythematous papules on his extremities. A chest X-ray revealed diffuse miliary infiltration. Mycobacterium tuberculosis DNA was demonstrated in bronchoalveolar lavage fluid by polymerase chain reaction. Histopathology of a skin biopsy showed poorly formed noncaseating granulomatous inflammation in the lower dermis and was positive for many acid-fast bacilli. Miliary tuberculosis of the lung and skin were diagnosed. The respiratory symptom and the skin lesions improved after treatment with anti-tuberculous drugs.     

Non-respiratory tuberculosis with Mycobacterium tuberculosis after penetrating lesions of the skin: five case histories.

Tuberculosis is primarily transmitted from person to person via the respiratory route. We describe five cases of patients who developed tuberculosis at the site of a skin injury: three after being treated repeatedly with local corticosteroids via intramuscular injections, and two who cut themselves accidentally with a knife. All cultures yielded normal-sensitive Mycobacterium tuberculosis, and all patients responded well to anti-tuberculosis treatment. These unusual manifestations of non-respiratory tuberculosis may support the assumption that persistent, painful, reddish and/or fistulous areas of the skin might also indicate an infection caused by M. tuberculosis, via either reactivation of pulmonary tuberculosis or primary infection with M. tuberculosis by cutaneous transmission.     

Tuberculosis cutis miliaris disseminata as a manifestation of miliary tuberculosis: literature review and report of a case of recurrent skin lesions

The development of severe adverse reactions to antituberculous drugs in a patient with miliary tuberculosis led to unorthodox, suboptimal antituberculous therapy. The patient's failure to respond to therapy was discovered when acid-fast bacilli were detected in new skin lesions. Such lesions have been described in the literature as tuberculosis cutis miliaris disseminata; 24 cases (in addition to that described herein) have been reported thus far. The patient eventually recovered completely after detection and drainage of a large retrofascial tuberculous abscess. This case illustrates the importance of careful examination of the skin in clinical medicine, as tuberculosis cutis miliaris disseminata is an easily overlooked sign of miliary tuberculosis.     

Transbronchial Cryobiopsy for Miliary Tuberculosis Mimicking Hypersensitivity Pneumonitis

Miliary tuberculosis is a potentially lethal type of tuberculosis that results from the hematogenous dissemination of Mycobacterium tuberculosis bacilli. We herein describe the case of a 34-year-old man that presented with a one-month history of cough and fever, while his sputum smear results were negative. Chest computed tomography revealed bilateral centrilobular ground-glass opacification (GGO), suggestive of hypersensitivity pneumonitis; thus, bronchoscopy was performed. Cryobiopsy specimens revealed necrotic granulomas. A re-examination of sputum after bronchoscopy identified Mycobacterium tuberculosis, and miliary tuberculosis was diagnosed. A cryobiopsy might be useful for diagnosing miliary tuberculosis pathologically, particularly when miliary nodules may be masked by GGO.     

Osteomyelitis and skin ulcers caused by Mycobacterium szulgai in an AIDS patient

Mycobacterium szulgai is a ubiquitious non-tuberculous mycobacterium causing infection in immunocompetent and immunocompromized patients. Clinically mimicking pulmonary tuberculosis in most cases described, rarely other manifestations occur. Here we report the case of an AIDS patient with osteomyelitis of the hand and toe, accompanied by multiple cutaneous ulcers of the chest and forearm. The case highlights the unusual combination of osteomyelitis and skin ulcers without pulmonary infection and describes the likely cutaneous route of infection in a patient who keeps tropical fish.     

Miliary tuberculosis and acute respiratory distress syndrome.

OBJECTIVE: Miliary tuberculosis is a life-threatening disease caused by the haematogenous spread of Mycobacterium tuberculosis. We evaluated the clinical manifestations of 34 patients with miliary tuberculosis. DESIGN: A retrospective case review. RESULTS: The diagnosis of miliary tuberculosis was based on the identification of miliary nodules on chest radiography and one of the three following criteria: 1) acid-fast bacilli smear and/or culture positive in clinical specimens (22/34), 2) histopathological identification of TB granuloma (6/34), and 3) radiological and clinical improvement after anti-tuberculosis treatment (6/34). The median age (+/-SD) of the patients was 42.7 +/- 21.6 years, with two peaks, in the age group 20-30 and in those over 60. There were 16 underlying diseases in 14 patients, of which liver cirrhosis was the most common. The drug sensitivity pattern was available for 17 isolates of M. tuberculosis: 14 were sensitive, while the other three were resistant to at least one anti-tuberculosis drug. Eight patients developed acute respiratory distress syndrome (ARDS), five of whom died during intensive care. Platelet count, serum albumin and liver enzyme level at the time of admission were significant factors both for ARDS development and for survival. CONCLUSION: ARDS caused by miliary TB is associated with a high fatality rate; scope remains for improvement in its management.     

Atypical presentations of cutaneous tuberculosis: Series of 10 cases

Cutaneous tuberculosis classically presents as Lupus vulgaris, scrofuloderma, tuberculosis verrucose cutis and tubercular abscess. Hypersensitivity reaction to the bacilli leads to Lichen scrofulosorum and papulonecrotic tuberculids. At the same time, it can have myriad of clinical presentations, many of which are still undescribed. It is important to regularly update ourselves with these unusual manifestations so as to ensure early treatment and reduction of overall morbidity. In this case series tuberculosis manifesting as rapidly progressing diffuse facial granulomas, sporotrichoid tuberculosis, tuberculosis mimicking squamous cell carcinoma, scrofuloderma as tubercular ulcer, lupus vulgaris with nasal septal perforation, lupus vulgaris resembling furuncle, psoriasis, dermatitis and BT Hansen are described in immunocompetent individuals. These cases highlight the importance of recognition of atypical forms of cutaneous tuberculosis to minimize scarring and dissemination of bacilli.     

The adult respiratory distress syndrome associated with miliary tuberculosis

Miliary tuberculosis is an unusual cause of acute, catastrophic pulmonary failure. In this report, we describe three patients with miliary tuberculosis who developed the adult respiratory distress syndrome. The diagnosis of tuberculosis was suspected early, appropriate therapy was initiated, and two patients survived. The experience with these cases serves to reemphasize the importance of maintaining a high index of suspicion for treatable precipitating disorders in patients with acute respiratory failure.     

Miliary tuberculosis: new insights into an old disease

Miliary tuberculosis is a potentially lethal form of tuberculosis resulting from massive lymphohaematogeneous dissemination of Mycobacterium tuberculosis bacilli. The emergence of the HIV/AIDS pandemic and widespread use of immunosuppressive drugs has changed the epidemiology of miliary tuberculosis. Impaired cell-mediated immunity underlies the disease's development. Clinical manifestations are non-specific and typical chest radiographic findings may not be seen until late in the course of the disease. Atypical presentations--eg, cryptic miliary tuberculosis and acute respiratory distress syndrome--often delay the diagnosis. Several laboratory abnormalities with prognostic and therapeutic implications have been described, including pulmonary function and gas exchange impairment. Isolation of M tuberculosis from sputum, body fluids, or biopsy specimens, application of molecular methods such as PCR, and histopathological examination of tissue biopsy specimens are useful for the confirmation of diagnosis. Although response to first-line antituberculosis drugs is good, evidence regarding optimum duration of treatment is lacking and the role of adjunctive corticosteroid treatment is unclear.     

A case of miliary tuberculosis showing acute respiratory failure during pregnancy]

A 36-year-old Philippine woman had had fever and general fatigue from September, 2006 (11th week of pregnancy). She was admitted with high fever, general fatigue and dyspnea on October 16, 2006 (13th week of pregnancy). A chest radiograph on admission showed bilateral miliary shadows and ground glass shadows. She already had severe hypoxia on admission. As acid-fast bacilli were positive in urine (Gaffky 8) and sputum (Gaffky 1), we diagnosed as miliary tuberculosis and pulmonary tuberculosis complicated with acute respiratory distress syndrome (ARDS). We treated her with antituberculosis chemotherapy, corticosteroid, sivelestat sodium hydrate, direct hemoperfusion using a polymyxin B immobilized column, and mechanical ventilation, but she died due to respiratory failure. We emphasize that in this case pregnancy has the risk of to causing disease progression of miliary tuberculosis and we should treat immediately and intensively for miliary tuberculosis complicated with ARDS.     

Atypical cutaneous findings in a patient with systemic lupus erythematosus

A previously diagnosed systemic lupus erythematosus patient presented with arthralgia, skin rash and muscular weakness. When treated with high-dose corticosteroids and methotrexate she improved, except for a persistent lesion in the hand which evolved into a profound ulcer, along with tender subcutaneous nodules in the calf. A skin biopsy disclosed necrotizing vasculitis with giant cell granuloma revealing acid fast positive bacteria on ziels nilsen staining. A chest X-ray disclosed miliary tuberculosis (TB). The patient was diagnosed as miliary TB with prominent cutaneous involvement and treated with four anti-tuberculous drugs with slow resolution of her systemic, pulmonary and skin signs.     

Cellulitis as a manifestation of miliary tuberculosis in a renal transplant recipient

Cutaneous involvement is an unusual presentation of tuberculosis (TB) and is rarely reported in renal transplant recipients. We describe a 37-year-old renal transplant recipient with disseminated Mycobacterium tuberculosis infection that presented as cellulitis. The organism was isolated from tissue and blood cultures. The patient was treated with quadruple anti-TB therapy for 12 months. Anti-TB therapy led to a complete resolution of TB lesions. We also provide a review of the literature on cutaneous TB in renal transplant recipients. Skin TB in renal transplant recipients usually occurs with nontuberculous mycobacteria. The spectrum of the skin lesions can be quite different and can mimic bacterial infections. Mycobacteriosis should always be included in the differential diagnosis of a skin lesion in renal transplant recipients.     

Active tuberculosis undiagnosed until autopsy

In this report 21 patients in whom tuberculosis was the primary cause of death, but which was not diagnosed until necropsy, are reviewed. Of the 21 deaths, 11 were due to pulmonary tuberculosis and 10 to miliary tuberculosis. Proper evaluation of the following factors might have led to the correct diagnosis in many of the patients: A family history of tuberculosis, prior pleurisy, a gastrectomy, diabetes mellitus or end-stage renal failure; all can be associated with an increased incidence of tuberculosis. A negative tuberculin skin reaction does not exclude the presence of active tuberculosis. In the search for Mycobacterium tuberculosis, the examination of just one or two sputum specimens is not an adequate bacteriologic investigation. A positive gastric smear can have diagnostic importance. Ascitic fluid findings can be characteristic of tuberculous peritonitis. A negative bone marrow aspirate for acid-fast bacilli does not exclude miliary tuberculosis. Significant anemia, high fever and leukopenia increases the possibility of tuberculosis. The persistence and/or progression of lung infiltration, irrespective of supposedly specific antibiotic therapy, strongly suggests tuberculosis. Miliary tuberculosis can present as an adult respiratory distress syndrome. All but one patient in this series had fever. The failure to diminish the pyrexia believed due to specific lung infections with presumably effective antibiotics, and the inability of therapy to control other conditions thought to cause the fever indicate the presence of tuberculosis. Tuberculosis, especially miliary disease, should be considered as a possible etiology of fever of unknown origin.If the diagnosis of tuberculosis is highly suggestive, even without bacteriologic confirmation, a therapeutic trial of antituberculosis drugs should be given.     

Angio-immunoblastic lymphadenopathy with hypogammaglobulinaemia complicated by miliary tuberculosis

Angio-immunoblastic lymphadenopathy is a systemic disease of unknown aetiology. It carries a high mortality mainly from infection which results both from the intrinsic immunodeficiency and its exacerbation by treatment with steroids and or cytotoxics. We report a case of angio-immunoblastic lymphadenopathy with the unusual feature of hypogammaglobulinaemia who died of miliary tuberculosis. We suggest that all patients with angio-immunoblastic lymphadenopathy who have inactive tuberculous foci should be given antituberculous prophylaxis.     

Miliary tuberculosis and necrotizing tuberculous fasciitis – An unusual coexistence in a rheumatoid arthritis patient

We report a case of a 65‐year‐old Korean female patient with rheumatoid arthritis, who presented with extensive necrotizing fasciitis of the gluteus muscles, as an unusual initial manifestation of miliary tuberculosis. The patient had been previously treated with conventional disease‐modifying antirheumatic drugs and low‐dose steroids for 7 years. However, she recently developed fever, warmth and painful swelling in her right buttock. Magnetic resonance imaging indicated necrotizing fasciitis of the gluteus muscles and a fasciectomy specimen revealed a Mycobacterium tuberculosis infection. Two weeks after a fasciectomy, miliary tuberculosis of the lung was diagnosed by high resolution chest computed tomography. Soft tissue infection due to M. tuberculosis should be included as a differential diagnosis in the immunocompromised host. Clinicians should be alert to the possibility of miliary tuberculosis even in the absence of respiratory symptoms and normal chest radiograph.     

Renal allograft tuberculosis

We present a case of miliary tuberculosis presenting as fever of unknown origin in an immunosuppressed patient following renal transplantation. Biopsy of the renal transplant revealed acid-fast bacilli histopathologically. Eye examination revealed bilateral choroidal tubercles. Recipients of kidney transplants with fever of undetermined aetiology should be investigated for tuberculosis and fundoscopy performed.     

Symptomatic intracranial tuberculoma revealed when the patient receiving therapy for miliary tuberculosis: a case report

We describe a 20 year old man with miliary tuberculosis of the lung, who was noted to have multiple intracranial tuberculomas on magnetic resonance imaging but not noncontrast head computed tomographic scan receiving antituberculous chemotherapy.     

A case of hemophagocytic syndrome associated with miliary tuberculosis

We reported a case of a 76-year-female with hemophagocytic syndrome caused by military tuberculosis. The patients had complained high fever over 38.0 degrees C and anorexia. Her chest X-ray and computed tomography revealed disseminated miliary shadows in both lung fields. Laboratory examinations revealed anemia, thrombocytopenia and liver dysfunction. Bonemarrow aspirate revealed tuberculous granulomas and tubercle bacilli by acid-fast stains, and hemophagocytosis by macrophages. We diagnosed as miliary tuberculosis and tuberculosis-associated hemophagocytic syndrome, and started antituberculous and steroid therapy. After these therapy, fever, laboratory examinations dramatically improved. In this case, serum IL-18, sICAM-1, sVCAM-1 were elevated. These cytokines and adhesion molecules were reported to elevate in both hemophagocytic syndrome and tuberculosis correlating with disease activity. We conclude that IL-18, sICAM-1, sVCAM-1 may play important roles in pathogenesis of tuberculosis associated hemophagocytic syndrome.
