A 49-year-old man, nonsmoker, was admitted to dermatology department and followed up for diffuse lepromatous leprosy. He was vaccinated with BCG and he had no past history of tuberculosis. Diagnosis of leprosy was documented based on histological and bacteriologic evidence: a slit skin smear from the ear lobe was positive for lepra bacilli (BI3+), histopathology from the lesion on the face showed granulomas consisting of epithelioid histiocytes and lymphocytes with central caseous surrounding vessels and nerves, and PCR of biopsy specimens were positive for Mycobacterium leprae. After successful treatment using dapsone (100 mg/day), rifampicin (600 mg/month), and clofazimine (300 mg/month and 50 mg/day) during twelve months, hypopigmented skin lesions on the trunk and congestive rhinitis disappeared and the slit skin smear was negative. One month after the end of the treatment, he presented with diffuse papulonodular lesions on the face and trunk, fever, and alteration of general status. On the basis of his symptoms, diagnosis of leprosy reaction (type II) was made and the patient was treated using prednisone at a dose of 40 mg/kg/day. Outcome was unfavorable after two months of corticotherapy, and we had to wait for two supplementary months before we could get clofazimine to add corticoid. After 1 month of this treatment, he presented with fever, weight loss, and asthenia. Clinical examination revealed fever of 39°C, nodular lesions over face, trunk, forearms, and dorsum of hands (Figures , , and ). He presented no neurologic impairment. Biological examination showed inflammatory syndrome: CRP 393 mg/L, total leukocyte count 16,2 × 109/L, neutrophilia 15,3 × 109/L, and lymphopenia 0,48 × 109/L. Serum creatinine and alanine aminotransferase were normal. HIV status was negative. Two out of three sputum samples were positive for acid fast bacilli. Chest tomography showed alveolar-interstitial opacities at the left lower lobe (). Bronchoscopy detected thickening of lower lobar bronchi, without malignancy in histopathology of biopsy specimens. The patient was treated by antitubercular treatment. One month after the onset of this treatment, there were only two nodular lesions on the trunk, fever disappeared, and general status improved.
A 72-year-old Tamil man presented with a 2-year history of trophic ulcers, auto-amputated fingers, and facial infiltration (Fig. ). He was a retired mason from a poor social back ground with low income and did not have any other medical diseases. A general examination and neurological examination was normal. There was no significant contact history of leprosy or TB. He had received a BCG vaccination. He was an ex-smoker of tobacco and an ex-drinker of alcohol. His evaluation confirmed the clinical diagnosis of leprosy with highly positive slit-skin smears and histological evidence of lepromatous leprosy. He also gave a history of constitutional symptoms, evening pyrexia, and loss of weight and appetite. His ESR was 113 mm/hour and a sputum examination revealed AFB along with positive Mantoux test of 14 mm and CXR evidence of pulmonary TB. Basic investigations are given in Table . He was evaluated for both congenital and acquired immunodeficiency status, which did not reveal any abnormality. Although treatment for both conditions was commenced (isoniazid 300 mg/day, rifampicin 450 mg/day, ethambutol 800 mg/day, and pyrazinamide 1500 mg/day and dapsone 100 mg/day and clofazimine 50 mg/day and 300 mg/once a month) in liaison with a respiratory team, he was lost to follow up.
