Palatal perforation in a patient with borderline lepromatous leprosy: leprosy still not eradicated.

Leprosy was eliminated globally in 2000, but it continues to be endemic in developing countries like India, Brazil and Indonesia, with a prevalence of 0.57/10 000 persons in India (2020). At the end of the year 2020, the prevalence was 129 389, and oral manifestation of the leprosy is luncommon. We hereby report a case of a female patient in her late 30s who presented with palatal perforation. Following a thorough history taking and full body clinical examination, we arrived at a diagnosis of leprosy, and prompt treatment was initiated. Knowledge of cases like this becomes important as the oral lesion is said to form an essential source of leprosy dissemination in the community, and awareness about them becomes crucial, demanding immediate attention.

Cutaneous ulceration as a presenting feature of type 1 lepra reaction: A case report.

Reactions in leprosy represent sudden shift in the immunological response and are seen in 11-25% of affected patients. It can be seen before, during or after the completion of multidrug therapy (MDT).1 Two types of reactions are recognized; Type 1 reaction (T1R), seen in borderline leprosy, affecting mainly skin and nerves; type 2 reaction (T2R) or erythema nodosum leprosum (ENL), seen in lepromatous leprosy, characterized by systemic features in addition to cutaneous lesions. Trophic ulcers and ulcerating ENL are well known entities while cutaneous ulceration in T1R is extremely rare; we describe an immune-competent woman with cutaneous ulceration as a presenting feature to highlight the need to recognize this entity at the earliest opportunity.

Intermediate or Borderline forms (BT, BB, and BL)

Leprosy is a long-term spectrum disease and can present various clinical and histopathological aspects. Between the two poles of leprosy, there is a wide range of types, consisting of intermediate or borderline forms. In this chapter, the clinical, histopathological, and bacilloscopic characteristics of the intermediate forms (borderlibe-tuberculoid [BT], borderline-borderline [BB], and borderline lepromatous [BL]) are presented and discussed. The main clinical and pathological characteristics that allow the diagnosis and classification of leprosy among the different borderline forms are described and illustrated in panel form, as well as their most significant clinical and histopathological differential diagnoses are also discussed. The clinical-pathological classification of this disease has important implications in the choice of the correct treatment, the understanding of the pathophysiology, and the development of the reaction phenomena typical of leprosy,.

Erythroderma as a manifestation of leprosy.

Erythroderma consists of erythema and scaling involving most or all of the body surface. This generalized eruption may be idiopathic, drug-induced or secondary to cutaneous or systemic disease. A 71-year-old man is reported presenting generalized erythema and desquamation with deck-chair sign, nail dystrophy, and plantar ulcers associated with loss of local tactile sensitivity. Biopsies from three different sites demonstrated diffuse lymphocytic infiltrate with incipient granulomas. Fite-Faraco staining showed numerous isolated bacilli and globi. The skin smear was positive. Clinical and pathological diagnosis of borderline lepromatous leprosy was confirmed. This report demonstrates that chronic multibacillary leprosy can manifest as erythroderma and thus should be included in the differential diagnosis.

Erythroderma as a manifestation of leprosy

Abstract: Erythroderma consists of erythema and scaling involving most or all of the body surface. This generalized eruption may be idiopathic, drug-induced or secondary to cutaneous or systemic disease. A 71-year-old man is reported presenting generalized erythema and desquamation with deck-chair sign, nail dystrophy, and plantar ulcers associated with loss of local tactile sensitivity. Biopsies from three different sites demonstrated diffuse lymphocytic infiltrate with incipient granulomas. Fite-Faraco staining showed numerous isolated bacilli and globi. The skin smear was positive. Clinical and pathological diagnosis of borderline lepromatous leprosy was confirmed. This report demonstrates that chronic multibacillary leprosy can manifest as erythroderma and thus should be included in the differential diagnosis.

Mid borderline leprosy in type Bα Blaschko linear pattern: a rare phenomenon.

INTRODUCTION: Leprosy is a chronic granulomatous disease caused by M. leprae. It is a great imitator as it can manifest in different unusual and atypical ways. Mid borderline leprosy (BB) is an unstable form representing the immunologic midpoint in the clinical spectrum. CASE REPORT: Here, we report a case of BB leprosy having classical inverted saucer-shaped lesions elsewhere on the body with a linear psoriasiform lesion over the left forearm following the lines of Blaschko. Biopsy from this lesion revealed granulomas consisting of equal admixture of epithelioid cells and macrophages without multinucleate giant cells suggesting mid borderline leprosy. CONCLUSION: Occurrence of lesions in a Blaschko linear pattern supports the role of genetic susceptibility to leprosy. The genetically vulnerable cells along the lines of Blaschko were infected while the surrounding cells remained unaffected. This explains the concept of locus minoris resistentiae due to cutaneous mosaicism.

Erythema nodosum leprosum presenting as sweet's syndrome-like reaction in a borderline lepromatous leprosy patient.

Erythema nodosum leprosum (ENL) is characterized by tender erythematous nodules, accompanied by fever, malaise, arthralgia, and systemic complications. Atypical clinical manifestations have been reported such as pustular, bullous, ulceration; livedo reticularis; erythema multiforme-like reaction; and Sweet's syndrome (SS)-like presentation. We reported a case of ENL reaction presenting as SS-like reaction in a borderline lepromatous leprosy patient.

Reactive perforating leprosy, erythema multiforme-like reactions, sweet's syndrome-like reactions as atypical clinical manifestations of Type 2 leprosy reaction.

Type 2 leprosy reactions commonly known as erythema nodosum leprosum, but various clinical manifestations of type 2 leprosy reaction were exist. The highlight of this case series was to report various atypical clinical manifestations of type 2 leprosy reaction such as reactive perforating leprosy, erythema multiforme-like reaction, and sweet's syndrome (SS)-like reaction.

[Borderline leprosy as a rare differential diagnosis]. / Borderline-Lepra als seltene Differenzialdiagnose.

History and clinical findings | A 42-year-old migrant from Brazil presented with persistent sensory disturbances, skin discolorations and local alopecia in the upper limbs. Decisive for the presentation in our Tropical Medicine Clinic were new occurrences of severe pain and redness and swelling in the area of the lesions that had already been assessed by a number of medical specialists without a clear diagnosis could be made. Investigations and diagnosis | The histological analysis of skin biopsies showed perivascular, perineural, periadnexial lymphocytic and granulomatous dermatitis. In a direct microbiological preparation individual acid fast bacilli could be detected (Ziehl-Neelsen stain). The electroneurographical examination demonstrated a sensitive peripheral-neurogenic damage with emphasis on the right median nerve and the left ulnar and radial nerves. Thermography revealed an increased heating or cooling threshold. The serological investigation by ELISA for IgM antibodies against the phenolic glycolipid (PGL-1) was positive (titer 1 : 1200). In summary, the diagnosis of borderline leprosy (infection with Mycobacterium leprae) with transition to multibacillary leprosy (according to WHO) and leprosy reaction type 1 was made. Treatment and course | We initiated an oral antimycobacterial therapy (multidrug therapy, MDT) with rifampin, clofazimine and dapsone for 12 months (WHO regimen for multibacillary leprosy). Leprosy reaction type 1 was treated with prednisolone and by increasing the dose of clofazimine. Analgesic therapy on demand was carried out with nonsteroidal anti-inflammatory drugs (ibuprofen). MDT and successful management of leprosy reaction lead to a rapid improvement of symptoms. Conclusions | Leprosy is an infectious disease occurring only rarely in Germany (average incidence of 1-2 cases per year) that is diagnosed almost exclusively among migrants. Main symptoms comprise non-itchy, reddish, touch insensitive skin lesions or nerve deficits. The diagnosis is based primarily on the clinical presentation, supplemented by pathogen detection, histology, neurophysiological findings and serology. Standard therapy is a combination of rifampin, clofazimine and dapsone (WHO scheme) for at least 6 months.

Estado reaccional leprótico en una paciente con osteosarcoma de tobillo / No disponible

La lepra es una enfermedad infecciosa, poco transmisible, de evolución crónica, causada por el Mycobacterium leprae, que se caracteriza por afectar la piel, los nervios periféricos, la mucosa de las vías respiratorias superiores además de otras estructuras. Se ha subestimado su prevalencia y permanece siendo un problema de salud pública, detectándose aún nuevos casos cada año. Después de la introducción de la multiterapia MDT tanto prevalencia como incidencia han disminuido. En la actual investigación se hace la presentación de un caso clínico, paciente femenina, de 49 años, con diagnóstico de Lepra Dimorfa, que tiene antecedentes de haber sido amputada hace tres años de miembro inferior izquierdo por osteosarcoma de tobillo

Leprosy is an infectious disease with a chronic evolution and its etiological agent is Mycobacterium leprae. The disease affects skin, peripheral nerves, upper respiratory tract and other structures. Its prevalence has been underestimated and continues to be a public health problem in many countries. After the introduction of MDT, both prevalence and incidence declined. This study is a presentation of a clinical case of a 49 year old woman diagnosed of dimorphic leprosy and a history of amputation three years earlier due to osteosarcoma of the ankle
