A 57-year-old Sinhalese woman presented to the dermatology unit of the National Hospital of Sri Lanka with extensive seborrheic dermatitis and tender facial induration (Fig. ) of 1-year duration. She was a homemaker from an urban area with poor social background. She did not have diabetes or hypertension. She had received a Bacillus Calmette–Guérin (BCG) vaccination. She did not smoke tobacco or drink alcohol. A skin biopsy taken from indurated facial plaque revealed evidence of borderline tuberculoid leprosy with type 1 reaction. She did not have hypopigmented anesthetic patches or thickened peripheral nerves in the rest of her body. She was commenced on multibacillary treatment for leprosy. A year later, she developed fever, loss of appetite, loss of weight, and widespread skin abscesses all over her body. Her body mass index (BMI) was within normal range and the rest of the general examination was normal. A respiratory examination revealed bilateral (B/L) coarse crepitations; a neurological examination was normal. Her erythrocyte sedimentation rate (ESR) remained persistently elevated at more than 120 mm/hour. She had inflammatory shadows in a chest X-ray (CXR). A sputum examination for AFB was positive and GeneXpert confirmed rifampicin resistance. At that time, she revealed a diagnosis of human immunodeficiency virus (HIV) infection and tuberculous lymphadenitis, which was made 5 years back, where she had taken 6-month TB treatment but had defaulted on antiretroviral therapy. During this presentation, her CD4+ count was 57/μL. The rest of the investigations are summarized in Table . There was no contact history of leprosy or TB. She was started on a multidrug treatment regime, which included intravenously administered kanamycin (15 mg/kg per day), orally administered ethambutol (800 mg/day), orally administered levofloxacin (750 mg/day), isoniazid (300 mg/day), orally administered ethionamide (500 mg/day), orally administered cycloserine (750 mg/day), and orally administered pyridoxine (10 mg/day). A repeated split skin smear was negative and she continued with multidrug treatment-multibacillary therapy (dapsone 100 mg/day and clofazimine 50 mg/day and 300 mg/once a month) for leprosy without rifampicin. Highly active antiretroviral treatment was restarted subsequently. At 6 months she had clinically, hematologically, and radiologically improved.
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.
