A 50-year-old Sinhalese man with poorly controlled diabetes mellitus presented with facial infiltration (Fig. ) and erythematous painful nodules over his lower limbs and trunk suggestive of lepromatous leprosy with erythema nodosum leprosum. He was a manual laborer with low BMI. The rest of the general and neurological examination was normal. He had received a BCG vaccination. He did not smoke tobacco and drank alcohol occasionally. A skin biopsy revealed evidence of foamy macrophages with well-developed grenz zone. He was commenced on multidrug treatment-multibacillary treatment for leprosy (dapsone 100 mg/day, clofazimine 50 mg/day and 300 mg/once a month, and rifampicin 600 mg/month) with prednisolone 40 mg daily for type 2 reaction. Twelve months later he developed generalized lymphadenopathy with low-grade evening pyrexia and elevated ESR (80–100 mm/hour). Both Mantoux and QuantiFERON Gold test were positive. A CXR remained persistently normal. He was negative for HIV and diabetes. Basic investigations are given in Table . A lymph node excision biopsy revealed suppurative inflammation with focal foamy histiocytes; a TB culture from the lymph node biopsy later showed growth of AFB. GeneXpert did not reveal rifampicin resistance. Therefore, he was started on TB treatment (isoniazid 300 mg/day, rifampicin 450 mg/day, ethambutol 800 mg/day, and pyrazinamide 1500 mg/day) by the respiratory physician for the treatment of extrapulmonary TB. At 6 months, he had improved clinically and biochemically.
A 65-year-old non-hypertensive, non-diabetic man presented with history of left sided chest pain associated with productive cough and breathlessness for seven days. There was no history of fever, haemoptysis and exertional increase in breathlessness. The patient was referred to our teaching hospital from Green Pastures Hospital (GPH), a tertiary care referral centre for leprosy. The patient was treated for leprosy with WHO multidrug therapy for multibacillary leprosy. The patient was currently on treatment for ulnar neuritis with prednisolone 30 mg once a day for last three months. There was no past history of tuberculosis as per GPH records or information provided by the patient.\nClinical examination revealed numerous hypopigmented skin lesions varying in size from 2 to 10 centimeters over the trunk. The left ulnar nerve was thickened. There was dullness and decreased breath sounds in the left infrascapular and axillary areas.\nThe laboratory investigations revealed hemoglobin: 14.4 mg/dl; total leukocyte count: 19.5×103; erythrocyte sedimentation rate: 60 mm at the end of first hour; serum creatinine: 1.4 mg/dl; and random blood sugar: 91 mg/dl.\nOne out of three sputum samples tested was positive for acid fast bacilli and the chest radiograph showed loculated pleural effusion suggesting long standing pleural collection in left hemi thorax with infiltrations bilaterally, more on left side.\nA diagnosis of borderline leprosy with concomitant pulmonary tuberculosis was made. The patient was referred to DOTS clinic of our teaching hospital and started on category-I treatment according to the guidelines of national tuberculosis programme of Nepal. The oral prednisolone was subsequently tapered and stopped. The patient's general condition improved and was on regular follow up.
