A 59-year-old male patient was admitted to our university hospital (Botucatu, SP, Brazil) complaining of a perianal suppurative ulcer developed two months before the first medical consultation. He was under therapy with prednisone 40 mg/day for six months due to a presumed diagnosis of a drug reaction. On physical examination, a clean 10-cm diameter phagedenic perianal ulcer (Figure ) and two longitudinal suppurative ulcers on the inguino-crural region were observed. During investigation, and soon after reducing the corticosteroid dose, disseminated erythematous papules and nodules were observed in the upper limbs (Figure ).Histopathology of the perianal ulcer revealed a dense histiocytic dermal infiltrate and a granulomatous inflammatory response with central caseous necrosis (Figure ). Fite-Faraco staining showed a few acid-fast bacilli and the hypothesis of cutaneous tuberculosis was raised. The histopathology of upper limbs papular and nodular lesions showed foamy macrophages with globi of bacilli, suggesting lepromatous leprosy (Figure ). The perianal and inguinal ulcers were considered uncommon manifestations of type 2 leprosy developed when corticosteroid was gradually diminished. The patient was treated as for multibacillary leprosy with multidrug therapy and thalidomide.\nFour weeks later, the patient had fever, weight loss, asthenia and worsening of the perianal ulcer (Figure ), but without erythema nodosum leprosum. With this clinical picture, new investigation was developed. The tuberculin skin test was positive (20 × 20 mm) and culture of M. tuberculosis – using a biopsy sample from the perianal ulcer – on Löwenstein-Jensen medium was positive (Figure ). Polymerase chain reaction (PCR) and DNA analysis from upper limb skin samples were positive for M. leprae (Figure ). With the new information the patient was finally diagnosed as presenting simultaneously lepromatous leprosy – type 2 reaction – and cutaneous tuberculosis expressed by the perianal ulcer. Screening for HIV, HBV or HCV infection as well as lung, renal or colon compromising were negative. Hence, the patient was treated with isoniazid, ethambutol and rifampin for nine months with complete healing of the perianal and inguinal lesions after two months (Figure ). After the tuberculosis treatment, the patient was submitted to additional multidrug therapy for 12 months with dapsone, rifampin and clofazimine with complete cure of leprosy.
A 34-year-old, non- smoker male was admitted, in September 2007, to the Department of Pulmonary Medicine, as a follow through case of border line lepromatous leprosy. He had complaints of breathlessness, loss of appetite with cough with expectoration for last two and half months and skin lesions over face, forearm and dorsum of hands with exfoliative skin lesions over fore arm for last two months and recurrent haemoptysis for last 25 days. He was on medication, tab. Dapsone 100 mg daily, tab. Clofazimine 500 mg daily and cap, Rifampicin 600 mg, once a month, for the last nine months. He had also taken oral Prednisolone for more than three months duration about six months back, for neurological complications. There was no past history of tuberculosis as per information provided by the patient. Clinical examination revealed multiple hypo pigmented skin lesions varying in size from 2 to 4 cms over the trunk with thickened left ulnar nerve and nodular lesions over face, forearm and dorsum of hands [Figure and ] and exfoliative skin lesions over fore arm []. His resting pulse rate was 102/min and blood pressure was 112/74 mmHg and his respiratory rate was 26/min. His general examination revealed no significant abnormality. His respiratory system examination revealed coarse crepts localized to left infraclavicular and axillary areas. Initially he was put on symptomatic treatment for hemoptysis. Subsequently, his chest X-ray showed a large cavity with a mass filled opacity confined to left upper zone and fibrotic changes in right upper zone []. Computed tomography of thorax revealed fibro-consolidation with cavitation in the anterior segment of left upper lobe, fibrotic nodule in both anterior and posterior segments of right the upper lobe []. Thus a possibility of aspergilloma with other possibilities was raised. The clinical examination of the rest of the system revealed no abnormality.\nHis blood biochemistry revealed total leucocyte count: 10,200/cmm, DLC: P 66 %, L 34 %. His PPD was 2219 mm induration. His sputum for AFB on three consecutive days was positive. Thus a diagnosis of pulmonary tuberculosis was confirmed. For leprosy, patient consulted the skin department, was diagnosed with borderline lepromatous leprosy (on the basis of slit skin smear) with type-II Lepra reaction (biopsy of nodular lesion revealed diffuse sheets of foamy macrophages centered around adenexal structures with heavy infiltration of lepra bacilli suggestive of Erythema Nodosum Leprosum). He was advised to stop Dapsone and started oral Prednisolone, Thaliodomide and Clofazimine.\nThus a final diagnosis of borderline leprosy with type-II lepra reaction with concomitant pulmonary tuberculosis was made. The patient was referred to DOTS clinic and started on category-I treatment. The oral prednisolone was subsequently tapered and stopped while the other antileprotic drugs continued. The patient's general condition improved and was on regular follow-up.
