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 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.
