This retrospective review presented the prevalence and manifestations of tuberculosis among renal transplant recipients in our center between 1987 and mid 2007. The prevalence of tuberculosis was 5/151 (3.3%) recipients with a median age of 49 years (range = 38-55). The median time of diagnosis after transplantation was 23 months (range = 1-47). All five patients had pulmonary tuberculosis. None developed extrapulmonary infection. Presenting symptoms were fever (60%), productive cough (80%), weight loss (40%), and hemoptysis (20%). One patient had non-parathyroid-related hypercalcemia. Cyclosporine dosage needed to be increased in all patients. Two subjects who experienced side effects of hepatitis and/or jaundice from rifampicin were switched to second-line drugs. Infection with Mycobacterial tuberculosis is a not uncommon problem in renal transplant recipients especially in endemic areas. Tuberculosis must be excluded for immunosuppressed patients with clinical or radiological suspicion.

One of the endemic fungi, Blastomyces dermatitidis, can cause epidemics of infection with multiple persons involved in a point source outbreak but more commonly causes sporadic cases of infection within the areas of endemicity. Blastomycosis can present as an acute pneumonia which is often misdiagnosed as acute pneumococcal pneumonia or the infection may present as a chronic pneumonia along with weight loss, night sweats, hemoptysis, and a lung mass suggesting tuberculosis or carcinoma of the lung. Extrapulmonary infection with B. dermatitidis is protean with many different manifestations. Most commonly, skin or subcutaneous lesions are found with either a verrucous or warty appearance or in an ulcerative form. Cases have been misidentified as keratoacanthoma, pyoderma gangrenosum, carcinoma, or as Weber-Christian panniculitis if there are nodular subcutaneous lesions. Essentially any site or organ can have lesions of disseminated blastomycosis. In our series, cases of laryngeal carcinoma, adrenal insufficiency, thyroid nodules, granulomatous hypercalcemia, abnormal mammograms thought to represent breast carcinoma, otitis media with cranial extension, immune thrombocytopenic purpura, and hemolytic anemia of unknown cause have been misdiagnosed and blastomycosis subsequently identified as the cause. This infection causes manifestations which mimic many other more commonly diagnosed conditions and must always be considered by clinicians practicing in the endemic region.

An 82-year-old man was admitted to our hospital with hemoptysis and weight loss. Chest computed tomography(CT) showed a 90 mm mass with cavity formation in the right lower lobe adjacent to chest wall. Laboratory data revealed hypercalcemia and elevation of parathyroid hormone-related protein C (PTHrP). He was diagnosed as squamous cell carcinoma of lung by transbronchial lung biopsy (TBLB) [cT3aN1M0]. Nausea and anorexia due to hypercalcemia became worse and a right middle and lower lobectomy was performed because of difficult control of symptoms by medicine and worsening of his general condition. His symptoms were improved immediately after surgery.

A 30-year-old female was symptomatic with headache, fatigue, and weakness since October 2011 and was told to have anemia. In January 2012, she was admitted outside with pulmonary edema. Investigations revealed advanced azotemia, anemia, and hypercalcemia. Urine showed 2 + proteins and 30-35 red blood cells. There was no history of oral ulcers, rash, Raynaud's phenomenon, or hemoptysis. She was evaluated for causes of rapidly progressive "renal failure." Hemolytic work-up; antinuclear antibody, double-stranded DNA, and anti-neutrophil cytoplasmic antibody were negative. Kidney biopsy was done and interpreted as acute interstitial nephritis with hyaline casts. She was started on hemodialysis and treated with steroids and cyclophosphamide. She came to our institute in January 2012. Investigations showed evidence of paraproteinemia with kappa restriction. Bone marrow showed 15% plasma cells. Kidney biopsy was reviewed and was diagnostic of cast nephropathy. She was treated with 6 monthly cycles of dexamethasone and bortezomib. She achieved complete remission in July 2012. Maintenance doses of bortezomib were continued until May 2014. Autologous bone marrow transplantation was performed on June 06, 2014. Monthly, bortezomib was continued till April 2015. Subsequently, workup for renal transplantation was started with her father as her donor. Test for sensitization was negative. Renal transplantation was done on January 1, 2016, with prednisolone, mycophenolate, and tacrolimus. She achieved a serum creatinine of 0.6 mg% on the 4th postoperative day. Thereafter, she continues to remain stable.

Thymic enlargement (TE) in Graves' disease (GD) is often diagnosed incidentally when chest imaging is done for unrelated reasons. This is becoming more common as the frequency of chest imaging increases. There are currently no clear guidelines for managing TE in GD. Subject 1 is a 36-year-old female who presented with weight loss, increased thirst and passage of urine and postural symptoms. Investigations confirmed GD, non-PTH-dependent hypercalcaemia and Addison's disease (AD). CT scans to exclude underlying malignancy showed TE but normal viscera. A diagnosis of hypercalcaemia due to GD and AD was made. Subject 2, a 52-year-old female, was investigated for recurrent chest infections, haemoptysis and weight loss. CT thorax to exclude chest malignancy, showed TE. Planned thoracotomy was postponed when investigations confirmed GD. Subject 3 is a 47-year-old female who presented with breathlessness, chest pain and shakiness. Investigations confirmed T3 toxicosis due to GD. A CT pulmonary angiogram to exclude pulmonary embolism showed TE. The CT appearances in all three subjects were consistent with benign TE. These subjects were given appropriate endocrine treatment only (without biopsy or thymectomy) as CT appearances showed the following appearances of benign TE - arrowhead shape, straight regular margins, absence of calcification and cyst formation and radiodensity equal to surrounding muscle. Furthermore, interval scans confirmed thymic regression of over 60% in 6 months after endocrine control. In subjects with CT appearances consistent with benign TE, a conservative policy with interval CT scans at 6 months after endocrine control will prevent inappropriate surgical intervention. Learning points: Chest imaging is common in modern clinical practice and incidental anterior mediastinal abnormalities are therefore diagnosed frequently. Thymic enlargement (TE) associated with Graves' disease (GD) is occasionally seen in view of the above. There is no validated strategy to manage TE in GD at present. However, CT (or MRI) scan features of the thymus may help characterise benign TE, and such subjects do not require thymic biopsy or surgery at presentation. In them, an expectant 'wait and see' policy is recommended with GD treatment only, as the thymus will show significant regression 6 months after endocrine control.
