A 29-year-old male, born to nonconsanguineous parents, presented with multiple skin coloured nodules and hyperkeratotic scaly lesions of 3-month duration. He initially developed asymptomatic skin coloured raised lesions over both the ear lobes. Over the next 2 months he developed multiple similar lesions over the trunk and both the extremities. He also gave history of generalised burning sensation for 15-day duration with low grade fever. There was no history of burning sensation in the eyes, nasal stuffiness, and sensory or motor weakness. The patient denied any drug intake, fever, myalgia, spontaneous blistering or ulceration, neuritic pain, and testicular pain. None of the family members or neighbours had suffered from leprosy. He denied any past history of infectious diseases but there was no history of immunization including Bacillus Calmette et Guérin (BCG) vaccination. He was a chronic alcoholic.\nHis general physical examination was normal with no madarosis or lymphadenopathy. Cutaneous examination revealed multiple, soft, succulent, nontender, skin coloured superficial nodules present bilaterally on the forehead, cheeks, ear lobes, forearms, back, and chest with sparing of palms and soles (). The surface of these nodules showed follicular plugging. Multiple verrucous plaques were seen over the right ankle (). Skin surrounding the plaques was erythematous. Neurological examination revealed thickened bilateral greater auricular, right common peroneal nerve, and tender left posterior tibial nerve. The rest of the musculoskeletal and neurological examination was normal. Routine haematological and biochemical investigations including urine, renal, and liver function test revealed no abnormality. His retroviral serology was negative. Chest X-ray was normal. Slit skin smear from the lesion showed a bacteriological index (BI) of 5+ and the perilesional skin had a BI of 2+.\nHistopathological examination of the wedge biopsy done from the forearm and back nodules revealed sheets of histiocytes aggregates along with lymphocytes and few polymorphs in perivascular and periadnexal location (Figures and ). There was collection of epithelioid cells (). Fite Faraco stain was strongly positive (). A diagnosis of borderline lepromatous leprosy with type 2 reaction was made.\nA wedge biopsy from the verrucous lesion on the right ankle was taken. Epidermis showed hyperkeratosis and parakeratosis with irregular acanthosis (). Dermis showed epithelioid cell granulomas along with lymphocytes and plasma cells (Figures and ). Zeihl-Neelsen stain for acid fast bacilli was positive (). GeneXpert MTB/RIF test based on Nucleic Acid Amplification, which detects MTB-specific region of the rpoB gene and uses real time-PCR (RT-PCR), was done on skin biopsy specimen. The result was positive. However, a culture was not done. Based on clinical and histopathological findings, a diagnosis of tuberculosis verrucosa cutis (TVC) was made.\nThe patient was treated with rifampicin, isoniazid, pyrazinamide, and ethambutol, in addition to dapsone and clofazimine along with a monthly supervised dose of clofazimine and rifampicin for first 2 months. Then rifampicin and isoniazid with dapsone and clofazimine were continued for further 4 months. After 6 months, treatment of leprosy was continued as for multibacillary leprosy. Type 2 reaction was treated with oral anti-inflammatory drugs. The patient tolerated the drugs well with control of type 2 reaction and regression of the TVC lesion.
A 50-year-old non-diabetic, non-hypertensive man who had completed treatment for lepromatous leprosy two years back, was admitted at Green Pastures Hospital for type-2 lepra reaction (erythema nodosum leprosum). There was a past history of lepra reactions for which he underwent treatment. Currently the patient was again being treated for the same with prednisolone 30 mg once daily, thalidomide 100 mg twice daily and clofazimine 50 mg once daily. However, information about initial screening of tuberculosis was not available.\nThe patient was referred to our teaching hospital with complaints of fever, productive cough and dyspnoea of three months duration. The patient also complained of pain and distension of abdomen and decreased appetite for three months.\nClinical examination revealed tense abdomen with shifting dullness, respiratory system with bilateral crackles with bronchial breath sounds predominantly in the left infra clavicular area, and skin showed no active lesions of erythema nodosum leprosum. The laboratory investigations revealed hemoglobin: 11.8 mg/dl; total leukocyte count: 5900/mm3; erythrocyte sedimentation rate: 110 mm in first hour; random blood sugar: 109 mg/dl; serum electrolytes, sodium: 135 meq/L and potassium: 3.2 meq/L.\nTwo out of three sputum samples were positive for acid fast bacilli. Chest radiograph showed multiple heterogeneous opacities in bilateral lung fields and a cavitary lesion in left upper zone. A diagnosis of pulmonary tuberculosis and provisional diagnosis of peritoneal tuberculosis were made.\nDermatologist's opinion was sought for the lepra reaction. The patient was advised to stop prednisolone as no active lesions persisted. He was subsequently referred to DOTS clinic and was started on category-I treatment.
