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 25-year-old man was admitted with complaints of fever, which was mainly in the evening, of nearly 1-week duration associated with cough, breathlessness, and generalized fatigue. He was on standard multidrug therapy (Rifampicin, Clofazamine, Dapsone) for lepromatous leprosy, for the last 2 years, but he was not very compliant with drug intake. He developed ENL for which he was started on steroids for the last 6 months. He did not have any addictions.\nOn examination he was sick looking, and had severe pallor, generalized lymph node enlargement, diffuse erythematous lesions, and nodular tender lesions of varying size all over the body. The scalp and oral mucosa were not involved. At the time of admission his temperature was 40°C, blood pressure was 120/70 mm of Hg and pulse rate was 114/m and respiratory rate was 38/m. Respiratory system examination revealed bilateral scattered crepitations and rhonchi. He had a hepatomegaly of 5 cm below the costal margin in the right midclavicular line and splenomegaly of 3 cm.\nInvestigations revealed Hb 6 g%, total leucocyte count 1000/mm3 (P 85%, L 15%), ESR 130 mm in the first hour, platelet count 3.2 lakhs/mm3, renal and liver function tests within normal limits, MCV 80, MCH 24, MCHC 30, reticulocyte count 3.5%. Peripheral smear showed normocytic normochromic cells with no evidence of hemolysis; WBCs were increased in number with predominance of neutrophils; and platelets were adequate. CRP was 160 mg/l, and slit-skin smear from the ear lobe was tested positive for lepra bacilli, BI 6%, MI 0%. X-ray chest was normal, sputum was positive for AFB, and HIV status was negative.\nWith the clinical scenario and investigation results the diagnosis of Hansen's disease, ENL, pulmonary tuberculosis, SIRS was made. He went into hypotension which was corrected with fluid replacement. Spo2 was maintained at 98%, without supplemental o2. He was started on broad spectrum antibiotics and DOTS CAT I ATT. The treatment for leprosy was continued. Fever subsided in 3 days and he was discharged.
