Abstract
A 32-year-old fisherman suffering from lepromatous leprosy presented with fever, joint pains, bullous lesions, and multiple well-defined ulcers on the extremities and back of 10-days duration. The bullae ruptured to form ulcers of varying sizes with well-defined margins and necrotic bases. A few of the ulcers had black crusts resembling eschars. An immunofluorescence study ruled out autoimmune bullous disease. Histopathology of a lesion showed features of erythema nodosum leprosum.

Abstract
BACKGROUND Several clinical and laboratory observations point to the possible microscopical affection of normal-looking skin in leprosy. OBJECTIVE This study was carried out to verify the microscopical affection of apparently normal-looking skin in different types of leprosy. PATIENTS AND METHODS The study included 50 patients with different clinical types of leprosy. Biopsies from both skin lesions and normal-looking skin were obtained from each patient and examined for microscopical evidence of leprosy. RESULTS Microscopical affection of normal-looking skin was detected in 52% of our cases, with higher incidence of affection towards the lepromatous end of the disease. CONCLUSION Our findings underscore that the incidence of microscopical affection of normal-looking skin in leprosy is much higher on the lepromatous end of the spectrum of leprosy than on the tuberculoid end; during treatment, the leprosy granulomas may disappear from the normal skin before the clinical lesions. Moreover, the microscopic picture of indeterminate leprosy can be observed in the normal-looking skin of patients with tuberculoid leprosy or lepromatous leprosy, and this description appears not to be confined to the entity known as indeterminate leprosy.

Abstract
A 49-year-old man with lepromatous leprosy treated with dapsone monotherapy for 12 years (1967 to 1979) reported in the hospital in 2003, with relapsed disease. A slit skin smear showed a bacteriological index of 4+. Biopsies from skin lesions before and after anti-leprosy therapy showed features of lepromatous leprosy. Both biopsies showed unusual features of bacillary clumps in epidermal cells demonstrating clearly that dissemination of M. leprae can take place even through unbroken skin. The presence of lepra bacilli in clumps in the epidermis is an indicator that the skin is a potential route of transmission of the disease.

Abstract
Ulcers with maculo-papular rash are an unusual presenting feature of leprosy. They occur as result of neuropathy, type-2 lepra reaction or Lucio's phenomenon. The hall mark of type-2 reaction is erythema nodosum. Very rarely it manifests as ulcerative skin lesions. We describe one such unusual case of a young male who presented with multiple ulcers and maculo-papular rash over the legs, chest and abdomen. In addition to this, he had fever, heart murmur, pulmonary infiltrates, neuropathy, and deranged liver function. A clinical differential diagnosis of infective endocarditis and systemic nectrozing vasculitis was made. Skin biopsy showed dense inflammation with lepra bacilli consistent with type-2 lepra reaction.

Abstract
Lucio phenomenon is a peculiar reactional state associated with Lucio leprosy; both exhibit a restricted global distribution. The exact underlying pathomechanism of Lucio phenomenon, which may be fatal at times, still needs further elaboration. A case of relapse of partially treated nodular lepromatous leprosy presenting with Lucio phenomenon is reported, along with a brief review of the literature.

Abstract
The immunomodulatory drug thalidomide is the treatment of choice for erythema nodosum leprosum (ENL), an inflammatory cutaneous and systemic complication of multibacillary leprosy. To elucidate the mechanism of action of thalidomide in this syndrome, we prospectively investigated 20 patients with ENL who were treated with thalidomide for 21 days. All patients responded to treatment, with the majority of them having complete resolution of cutaneous lesions within 7 days. This response was associated with a marked but transient increase in ex vivo mitogen-induced expression of interleukin (IL)-2 and interferon- gamma by CD4(+) and CD8(+) T cells that was observed on treatment day 7, but these returned to pretreatment levels by day 21. Plasma tumor necrosis factor- alpha levels were not high at baseline, and they increased modestly during treatment. Plasma levels of IL-12 increased steadily during thalidomide treatment. Hence, the therapeutic effect of thalidomide in ENL appears to be associated with transient immune stimulation, which suggests that the drug may promote an active immunoregulatory response.

Abstract
Skin lesions in lepromatous leprosy (LL) are usually multiple and widespread. Though the lesion may occur anywhere on the skin, male genitalia is rarely involved. In all cases reported so far about penile lesions of LL, there were lesions on the other parts of the body also. In some of the cases scrotum was also involved. We report here a patient who presented himself with a single macular lesion of leprosy on the shaft of his penis diagnosed as a case of lepromatous leprosy on slit-skin smear and histopathological examinations.

Abstract
The clinical and histologic experience with 30 patients who had Lucio's phenomenon, and pure and primitive diffuse lepromatosis (Latapi's lepromatosis) has been reviewed. The unanticipated clinical findings were a male to female ratio of nearly 1:1, a 21 month median time of onset of erythema nodosum leprosum (Type 2 reaction) after starting antibacterial treatment, and an absence of a stocking-glove pattern of anesthesia in 7 patients. The only unanticipated histologic finding was a lepromatous-granulomatous vasculitis, occurring in comparatively large vessels, or in vessels made large by pathologic changes, located near the dermal-subcutaneous interface. This finding was present in 6 of the 22 patients with histologic material available for review. In 2 of these 6 this vasculitis was identified before the onset of Lucio's phenomenon. With one conspicuous exception, the onset of treatment with a microbicidal agent was associated with a cessation of new lesions of Lucio's phenomenon within one week. Long-term morbidity, other than Type 2 reaction, was found in 22 of the 25 patients followed for more than 1.3 years. Usually this was the consequence of Latapi's lepromatosis, specifically venous insufficiency and/or loss of protective sensation, and only rarely from Lucio's phenomenon, specifically scar formation. Briefly summarized are the seven patients who had had a skin biopsy before the onset of Lucio's phenomenon, as well as the two patients who were considered to be atypical. Criteria for the diagnosis of Latapi's lepromatosis, in the absence of Lucio's phenomenon, are also considered.

Abstract
Erythema nodosum leprosum necroticans is an uncommon manifestation of type 2 lepra reaction, encountered in lepromatous and borderline lepromatous cases of leprosy. We report an unusual clinical presentation of necrotic erythema nodosum leprosum in a 9-year-old boy with no pre-existing evidence of leprosy. The lesions resolved completely following multi-bacilliary multi-drug therapy for 12 months, non-steroidal anti-inflammatory drugs and corticosteroids.

Abstract
BACKGROUND Even after 12 months of multi-drug therapy (M.D.T.) multibacillary (MB) therapy patients with high bacterial index (B.I.) continue to harbor dead bacilli and viable persisters, which lead to immunological complications such as recurrent reactions and late relapses, respectively. To achieve faster killing of viable bacilli and clearance of dead bacilli, various immunotherapeutic agents (vaccines and cytokines) are being evaluated as an adjunct to M.D.T. Aims and objectives. To evaluate the role of BCG and Mw vaccines in the immunotherapy of leprosy. MATERIALS AND METHODS Sixty untreated leprosy patients with a BI = 2 were randomly allocated to three treatment groups of twenty patients each. Group A patients received World Health Organization (W.H.O.) (12 months M.D.T.-MBR) and BCG intradermally (105 live bacilli/per dose). Group B patients were administered 12 months M.D.T.-MBR and Mycobacterium w (1 x 108) killed bacilli as first dose and 0.5 x 108 /dose in subsequent doses. Group C received 12 months M.D.T. MBR with 0.1 ml of normal saline as placebo. All the groups received 4 doses of vaccine or normal saline repeated at three monthly intervals. The patients were periodically monitored by clinical (Ramu's score), bacteriological (slit skin smear), and histopathological (skin biopsy) parameters, six monthly during and one year after completion of M.D.T. RESULTS The mean reduction in clinical scores in BCG and Mw groups was significantly more when compared to controls. At 12 and 24 months, the patients in BCG group had significantly greater reduction in Ramu's score as compared to those in the Mw group. BI declined by 2.40 units/year in patients receiving BCG, 2.05 units/year in the Mw group and 0.85 units/year in the control group. Although the incidence of type 1 reactions was apparently more in the BCG and Mw vaccinated groups, the incidence of type 2 reactions, neuritis and development of new deformities was less as compared to the controls. CONCLUSIONS In our study, BCG exhibited slightly better and faster effect on bacteriological clearance and clinical improvement as compared to Mw vaccine in borderline lepromatous (BL)/ polar lepromatous (LL) patients with a high initial B.I., however, their effect on histopathological (decrease in GF) improvement was comparable. Both the vaccines were well tolerated. Immunotherapy can be a useful adjunct to the shortened (12 months) M.D.T. MB regimen to decrease the risk of reactions and relapses in highly bacilliferous BL/LL patients.

Abstract
The identification of one or several hypochromic patches (HP) on the skin is a key stage in the diagnosis of leprosy on dark skin. However, HP are often caused by other disorder than leprosy. A study to determine the prevalence and causes of HP among children was carried out in a rural area of Mali in November 2001. All children under 15 years of age in two villages in an endemic area were screened by two dermatologists. Among the 1729 children seen, HP were identified in 71 patients, with a prevalence of 4.1%. The most common cause of HP was tinea versicolor, which was present in 39.4% of children with HP, followed by pityriasis alba in 31%, naevus achromicus in 24% and vitiligo in 5.6%. No case of leprosy was detected. Our study raises several points with practical consequences for the detection of leprosy cases: the high prevalence of non-leprous HP compared to leprosy, the reliability of the clinical diagnosis of leprosy, and the role of general health care workers in the detection of leprosy cases. Helping those who should be involved in that detection in distinguishing true cases from other hypochromic disorders appears to be a priority.

Abstract
Histoid lesion, a variety of lepromatous leprosy, is due to alteration in the growth pattern of Mycobacterium leprae, possibly due to loss of immunity in localized areas. The distinction is based on cellular morphology by demonstrating pallisading arrangement of multi-layered spindle-shaped histocytes. Cytodiagnosis by fine needle aspiration cytology is therefore an early tool to recognize the histoid variety, differentiating it from a conventional LL module, as it is a simple and less traumatic procedure.

Abstract
Leprosy commonly affects the peripheral and cranial nerves. This involvement often manifests with peripheral neuropathy, occurring as a result of direct invasion of the nerves by lepra bacilli. Immune-mediated neuropathy occurring in leprosy, as part of lepra reaction, has been described earlier. We report here two cases of Guillain-Barre syndrome occurring in patients with leprosy who did not have any obvious evidence of lepra reaction.

Abstract
Biopsies from radial cutaneous nerves of a lepromatous patient and one borderline lepromatous patient treated with 12 doses of multidrug regimen were studied using light and electronmicroscopes. Histopathologically both showed typical lepromatous neuritis. Electronmicroscopic examination showed demyelination, atrophy and degeneration of myelinated axons and nonmyelinated axons and a marked increase in collagen fibrils. Perineurial cells, Schwann cells and endoneurial macrophages contained numerous persisting M. leprae. Almost all the organisms in macrophages were fragmented and could be considered non-viable. A few M. leprae found in Schwann cells showed structure of viable bacilli. It is possible a few dead or dormant organisms may persist for many years in Schwann cells or in fibrous tissue without producing any ill effects, and may cause relapse only in rare instances. Since 12 months of MDT resulted in the clearance of M. leprae in course of time and the reported relapse rates after years were insignificant, implementation of MDT for a year for all MB patients is justified provided surveillance of these patients is ensured. Administration of uniform MDT for 6 months is worth a trial.

Abstract
In lepromatous leprosy, it may be postulated that apparently normal areas of skin are the probable sites of future extension of the pathological process and the events taking place in these site might represent the earlier stages of such an extension. Thus the present study has been done to evaluate any such changes in the apparently normal oral mucous membrane of the lepromatous leprosy patients, since oral involvement is common in these patients. Twenty two cases of lepromatous leprosy were studied histologically to see changes in apparently normal oral mucosa. Out of the 22 patients, apparently normal skin biopsies were taken from 13 patients and 5 lesional biopsies were taken from the same patients. Apparently normal oral mucosal biopsies were done for all patients. Biopsies of 22 cases of apparently normal oral mucosa did not show granulation formation of acid-fast bacilli histologically. The only change present was mild inflammation.

Abstract
A retrospective analysis of patient's leprosy clinic records at PGIMER, Chandigarh, India for the period 1983 to 1998 was undertaken to study the frequency, time of onset, and risk factors for leprosy reactions. Of the 2600 cases analyzed, 1494 were multibacillary and 1106 had paucibacillary disease. Presentation with reaction was common with 30.9% of our patients having reactions at the time of first visit. The incidence of reversal reaction (RR) was highest during 6 to 12 months after starting multi-drug therapy (MDT), thereafter declining gradually. Late RR occurred in 9.5% of all cases and was noted up to 7 years after treatment. Female gender, widespread disease, and multibacillary disease were identified as risk factors for RR. Erythema nodosum leprosum (ENL) reactions were noted to occur mostly during second or third year after starting MDT. Of the total number of patients who experienced ENL, 64.3% had recurrent episodes which continued for up to 8 years after the start of treatment. Lepromatous leprosy, female gender, and high Bacterial Index (>/=3) were recognized as risk factors for developing ENL. Occurrence of recurrent and late reactions, even though of mild severity, highlights the importance of recognizing and treating them promptly to prevent or reduce morbidity, complications, and further deterioration in the disability status. Although it is hoped that leprosy will have been eliminated at all levels by 2005, the recognition and management of these reactions will continue to be the most essential/significant task in the post elimination era.

Abstract
This study is a retrospective analysis of 147 cases of leprosy reaction selected out of 942 cases of leprosy registered between 1992 and 2002 at the RLTRI, Aska (Orissa). The occurrence of reaction was about 16% with a slight increase over the years. There was a preponderance of males, with about 80% cases among males, and the peak occurrence of reaction was found in the age-group of 21-49 years. Reversal reaction (RR) was seen in 68.7% and ENL in 31.3% of cases. Single episode of RR and ENL reactions was seen in 61.2% and 43.5% respectively. In either type the last episode was seen even after about 32 months after RFT. There was a dissociation between nerve and skin manifestation, with both skin and nerve manifestation in 78.96%, skin lesions only in 21.1% and nerve lesions only in 50.9% of cases. About 88% of reaction was seen in MB patients, with a higher proportion of RR, because of inclusion of more borderline cases. Prednisolone was the drug of choice in both types of reaction, though in 17 cases of steroid dependency, thalidomide was proved to have an edge over steroids. Both types taken together, in half of the cases the first episode of reaction developed within 6 months of starting treatment. Multiple episodes were more common with ENL.
