Pancreatic tuberculosis: A systematic review of symptoms, diagnosis and treatment.

INTRODUCTION: Although pancreatic tuberculosis (TB) is traditionally considered to be a rare clinical entity, in recent times, an increase in the number of reports of pancreatic TB has been noted. We conducted a systematic review in order to summarise currently available data on pancreatic TB. METHODS: A comprehensive literature search of Medline, Scopus and ISI Web of Science databases was conducted in order to identify papers reporting cases of pancreatic TB. The eligibility criteria for inclusion in the review required that the studies reported patient(s) affected by pancreatic TB and that individual data on age, sex, clinical presentation and outcome were available. RESULTS: In total, 116 studies reporting data on 166 patients were included in the analysis. The majority of patients were males (62.1%) diagnosed at a mean age of 41.61 ± 13.95 years. Most cases were diagnosed in Asia (50.0%), followed by North America (22.9%), Europe (20.5%), Africa (4.2%) and South America (2.4%). Human immunodeficiency virus (HIV) infection was diagnosed in 25.3% of those affected. Pancreatic TB most frequently presented itself in the form of a pancreatic mass (79.5%) localised mainly in the head (59.0%) and less frequently in the body (18.2%) and tail (13.4%). Extrapancreatic TB involvement most frequently affected the peripancreatic lymph nodes (47.3%). More than half of patients (55.2%) were subjected to laparotomy, while 21.08% underwent endoscopic ultrasound fine-needle aspiration biopsy. The presence of TB was identified most frequently through histological analysis (59.6%), followed by culture (28.9%), staining (27.7%) and, in a smaller number, by polymerase chain reaction (9.6%) and cytology (6.6%). Almost all patients received anti-tubercular pharmacological therapy (98.2%), while 24.1% underwent surgery. Despite treatment, 8.7% of patients died. CONCLUSION: Increased awareness of pancreatic TB is needed, not only in endemic areas but especially in relation to HIV infection and other clinical conditions associated with immunoincompetence.

Synchronous presentation of two rare forms of extrapulmonary tuberculosis.

Tuberculosis (TB) remains one of the leading infectious causes of death throughout the world. Extrapulmonary forms, namely adrenalitis and prostatitis, are rare presentations of TB and pose a difficult diagnostic challenge, given their non-specific manifestations. The authors present a case of a 42-year-old man with long-standing symptoms of fatigue, anorexia, weight loss, nightly fever and sudoresis. He also suffered from sporadic vomiting and episodic hypotension, and had skin hyperpigmentation, as well as frequent urination, perineal discomfort and pain at ejaculation. Laboratory investigation confirmed primary adrenal failure. On CT scan there were two hypodense right adrenal nodules and bilateral lung condensations with a tree-in-bud pattern. Another hypodense nodule was seen in the prostate. TB was diagnosed by isolatingMycobacterium tuberculosisfollowing cultures of bronchoalveolar lavage, bronchial secretions, urine and ejaculate. Antibacillary treatment resolved the infectious lesions but the patient remained on corticosteroid replacement therapy for ongoing adrenal failure.

Adrenal tuberculosis mimicking a malignancy by direct hepatic invasion: emphasis on adrenohepatic fusion as the potential route.

A 64-year-old female with primary adrenal insufficiency presented with a right adrenal mass showing quantitative nonadenoma features on dedicated adrenal computed tomography (CT). CT showed direct invasion of the mass to the adjacent hepatic parenchyma, and high uptake was noted on 18F-fluorodeoxyglucose positron emission tomography/CT. Laparoscopy revealed gross invasion of the adrenal lesion into the liver, which led to the en bloc resection including the involved liver. Polymerase chain reaction analysis of the surgical specimen revealed adrenal tuberculosis.

Association of tuberculous thyroiditis and papillary carcinoma of the thyroid: a rare coincidence.

We report the case of a 25 year-old patient with no medical history, admitted to our unit for nodular goiter of the right lobe without clinical or laboratory signs of hyperthyroidism. We carried out a right lobo-isthmectomy revealing the association of tuberculosis and thyroid papillary carcinoma. A left lobectomy has, therefore, been performed in a second stage. The patient underwent a six-month antituberculosis treatment with a good clinical outcome. We discuss this rare association and its best diagnostic and therapeutic support, with a review of the literature.

Thyroid tuberculosis with abnormal thyroid function--case report and review of the literature.

OBJECTIVE: To report an extremely rare case of thyroid tuberculosis (TT) with abnormal thyroid function and to review the related literature. METHODS: We present the patient's history, clinical findings, laboratory test results, imaging examinations, cytological data, management, and follow-up. In addition, we perform a review of the previously published cases of TT and give special attention to those with hypothyroidism. RESULTS: A 45-year-old Indian man presented to the outpatient clinic with neck swelling and respiratory and constitutional symptoms. Cervical ultrasound revealed a thyroid nodule and a necrotic right cervical adenopathy. Fine-needle aspiration cytology (FNAC) was performed and purulent material was removed from thyroid and lymph node. In both specimens, the culture was positive for Mycobacterium tuberculosis complex, and a cytological examination revealed epithelioid cell granulomas and necrosis. Mycobacterium tuberculosis complex was also identified by sputum culture. Antibiotic testing revealed sensitivity to all first-line drugs. A diagnosis of disseminated tuberculosis with thyroid and cervical lymph node involvement was made. Thyroid function was consistent with subclinical hyperthyroidism that subsequently evolved to hypothyroidism, requiring thyroid hormone replacement, and reflected tuberculous thyroiditis. Anti-tuberculosis drugs were started with good therapeutic response. CONCLUSION: TT is a rare condition and its association with thyroid function abnormalities is even rarer. To our knowledge this is the third report of hypothyroidism related to TT and the first to identify a period of hyperthyroidism preceding hypothyroidism. Despite its rarity, TT should be considered in the differential diagnosis of neck mass. FNAC is a useful procedure and thyroid function should be monitored.

Thyroid tuberculosis - role of PCR in diagnosis of a rare entity.

BACKGROUND: Tuberculosis is a rare cause of granulomatous thyroiditis, whose diagnosis may be difficult with routine cytopathology and staining for acid-fast bacilli (AFB). STUDY DESIGN: Amongst 7962 cases of various thyroid lesions subjected to fine needle aspiration cytology (FNAC) over a period of 12 years, 34 cases (0.43%) were found to have cytological features of granulomatous inflammation with or without necrosis, which could be due to tuberculosis, granulomatous thyroiditis or other causes of granulomatous inflammation such as sarcoidosis or fungal infections. DNA was extracted from the material available on May-Grünwald-Giemsa-stained smears from the archival material. PCR for Mycobacterium tuberculosis was performed for insertion sequence IS6110. RESULTS: The age of the patients ranged from 32 to 58 years (median 48 years); 24 were female and 10 male. FNAC from thyroid swellings showed epithelioid granulomas with giant cells and/or necrosis. Although acid-fast bacilli were only seen in smears in two cases, 19/34 (55.9%) showed the presence of 123 bp DNA band under ultraviolet transillumination. Five control cases were negative. CONCLUSION: Our study of archival cytological material illustrates the importance of PCR as a potentially useful tool for the detection of M. tuberculosis DNA from FNAC of thyroid lesions, which could provide an alternative for rapid diagnosis of thyroid tuberculosis in AFB-negative cases.

Fine needle aspiration cytology and immunocytochemistry in tuberculous thyroiditis: a case report.

BACKGROUND: Tuberculosis of the thyroid is very rare and does not strike the clinician as a first clinical diagnosis of a thyroid nodule. To our knowledge, only 40 cases of tuberculous thyroiditis diagnosed by fine needle aspiration cytology (FNAC) are described in the English literature. CASE: We report a case of tuberculous thyroiditis in a young woman who presented with a right-side solitary thyroid nodule of short duration (15 days), diagnosed by FNAC and confirmed by positive immunocytochemistry with monoclonal antibody to Mycobacterium tuberculosis complex. Ziehl Neelsen staining for acid-fast bacilli (AFB) was negative. CONCLUSION: FNAC provides a confident preoperative diagnosis of thyroid tuberculosis, obviating the need for unnecessary surgical removal of thyroid nodule. Immunocytochemistry is an important diagnostic adjunct to FNAC in AFB-negative cases.

Tuberculosis of the submaxillary gland is uncommon. Surgery is often necessary. Histologic analysis and the bacteriology made the diagnosis.

Tuberculosis of the thyroid: two case reports.

Tuberculosis of the thyroid gland occurs only rarely. Since extrapulmonary tuberculosis is now seen relatively more frequently the existence of this condition should be recognized. The cases of two patients with tuberculosis involving the thyroid are presented. The first, an Asian immigrant, presented with a painless goitre with no evidence of tuberculosis elsewhere. The second was an English woman who presented with hypothyroidism due to destruction of the thyroid by tuberculosis, and who subsequently died with disseminated tuberculosis; this is the only case to report the association between myxoedema and tuberculous thyroiditis. Other manifestations of thyroid tuberculosis and the pathological types are discussed.
