Autologous hematopoietic stem cell transplant in a patient with leprosy: Is it safe?

A patient with non-Hodgkin lymphoma, preparing for an autologous hematopoietic stem cell transplant (HSCT), developed leprosy. The patient was successfully treated with rifampicin, ofloxacin, and doxycycline, and the HSCT was performed without complications, being the first report, to our knowledge, of leprosy in an autologous HSCT patient.

Hanseníase virchowiana difusa e o diagnóstico diferencial com outras doenças sistêmicas / Lepromatous leprosy and the differential diagnosis with other systemic diseases

A Hanseníase é uma doença causada pelo Mycobacterium leprae, com manifestações cutâneas acompanhadas de perda da sensibilidade e envolvimento de sistema nervoso periférico, podendo acometer vísceras e mucosas. O Brasil ocupa o 2° lugar no ranking de prevalência da doença. A classificação própria da hanseníase evidencia sua complexidade clínica e polimorfismo; e possibilita intersecções com patologias como o linfoma não Hodgkin. Este é uma neoplasia maligna de linfonodos, e pode manifestar-se primariamente na pele. Paciente masculino, 51 anos. Procurou o serviço com queixa de “pele rachada”, lesões em boca e língua, e emagrecimento. Ao exame físico, presença de placas em palato, formações esbranquiçadas em dorso de língua e infiltração em lóbulo de orelha. Identificaram-se ainda, alterações sensitivas em extremidades, rash cutâneo eritemato-descamativo generalizado, tumoração em cotovelo, e lesões eritemato-infiltradas com exulcerações em membros inferiores. As hipóteses diagnósticas foram: hanseníase, leishmaniose cutâneo-mucosa, SIDA, Sífilis secundária e linfoma não Hodgkin. Durante a investigação, obtiveram-se resultados negativos para todas as sorologias, exceto a pesquisa de BAAR e biópsia sugerindo Hanseníase Virchowiana. Iniciou-se tratamento poliquimioterápico e houve remissão completa das lesões. Na hanseníase virchowiana, notam-se lesões sólidas papulosas, nodulares, ou em placas com características variáveis. Além disso, é possível encontrar espessamento de pavilhão auricular, madarose e obstrução nasal. Lesões em cavidade oral, também são descritas nestes casos. Os linfomas não Hodgkin de apresentação cutânea primária, podem se assemelhar a formas difusas de Hanseníase virchowiana, pois são neoplasias linforreticulares que se manifestam durante a história natural da doença em tecidos extranodais, dentre eles, a pele.

Leprosy is a disease caused by Mycobacterium leprae, with skin manifestations accompanied by loss of sensation and involvement of the peripheral nervous system that can also affect mucous membranes and viscera. Brazil ranks 2nd in the ranking of disease prevalence. The classification of leprosy itself shows its clinical polymorphism; and allows intersections with diseases such as non-Hodgkin lymphoma. This is a malignant neoplasm of lymph nodes, and may manifest primarily inthe skin. A 51 years-old male patient came to us complaining of “chapped skin”, lesions in the mouth and the tongue and weight loss. On physical examination there was the presence of plaques on the palate, whitish formations on back of tongue and ear lobe infiltration. We identified sensory changes, widespread erythematous rash, a tumor in the elbow, and infiltrated erythematous lesions with exulcerations in lower limbs. The diagnostic hypotheses were: mucocutaneous leishmaniosis, AIDS, secondary syphilis, leprosy and non-Hodgkin lymphoma. During the investigation, all serological test were negative, however, acid fast bacilli staining and biopsy suggested lepromatous leprosy. After multidrugtherapy treatment there was complete resolution of the lesions. In lepromatous leprosy solid nodular, papular lesions or plaques with variable characteristics may be noticed. Additionally, thickening of the pinna, madarosis and nasal obstruction can be found. Lesions in the oral cavity are also described in cases of lepromatous leprosy. Non-Hodgkin lymphomas with primary cutaneous presentation, may resemble indeterminate forms of leprosy, since they are characterized as lymphoreticular neoplasms that arise during the natural history of the disease, in extranodal tissues, including the skin.

Lepromatous lymphadenitis masquerading as lymphoma.

A 70-year-old male presented with multiple lymphadenopathy and a strong clinical suspicion of non-Hodgkin's lymphoma. Cervical and axillary nodes were excised and were sent for histopathological evaluation, which revealed aggregates of lepra cells loaded with lepra bacilli. Clinicians practising in leprosy endemic areas should keep lepromatous lymphadenitis in mind while investigating patients with lymphadenopathy.

Fatal disseminated strongyloidiasis in patients on immunosuppressive therapy: report of two cases.

Disseminated strongyloidiasis is a rare manifestation in patients on immunosuppressive drugs. We report two cases of fatal disseminated Strongyloides stercoralis infestation. The first was in a patient of pemphigus vulgaris who developed an exacerbation of symptoms, one year after diagnosis and was given intravenous dexamethasone and azathioprine and in the third week of hospitalization developed features of septicemia, respiratory failure and petechial hemorrhages which were proven to be due to disseminated strongyloidiasis. The second patient was diagnosed to have stage IV diffuse large cell type of non-Hodgkin lymphoma and after the second cycle of chemotherapy, developed generalized symptoms of septicemia, respiratory failure, purpuric macules and patches. This was also proven to be disseminated strongyloidiasis.

Chronic macrocheilia: a clinico-pathological study of 28 patients.

Chronic macrocheilia has a multifactorial aetiology and is often a diagnostic and therapeutic challenge. Epidemiological information on this condition is scarce, most of the data reported relating only to granulomatous cheilitis. We have performed a detailed clinico-pathological analysis of all patients with chronic macrocheilia presenting to us during the last 6.5 years. Of the 28 patients identified, 13 (46.4%) had granulomatous cheilitis (GC), six (21.4%) had tuberculosis of the lip, three (10.7%) had leprous macrocheilia, two (7.1%) had multiple endocrine neoplasia type IIb, and one each had Ascher's syndrome and non-Hodgkin's lymphoma. Two patients were diagnosed as 'nonspecific cheilitis'. Histopathological differentiation between tuberculosis and GC was often not possible; but PCR for Mycobacterium tuberculosis was positive in all patients with tuberculosis and negative in four patients with GC in whom M. tuberculosis was sought. In spite of detailed clinical examination and investigations, a therapeutic trial was required to confirm the diagnosis in five (17.9%) patients. We have reviewed the available literature on this subject, and to our knowledge this study is the first of its kind. More such studies from other centres will help physicians to make an accurate aetiological diagnosis and treat this uncommon but disfiguring condition with confidence.

Os autores relatam caso de linfoma não Hodgkin em paciente do sexo feminino, de 28 anos, ressaltando o diagnóstico diferencial com formas multibacilares de hanseníase. Além de achados clínicos passíveis de confusão, a histologia mostrava, de modo não usual, infiltrado inflamatório mononuclear perineural e perianexial

Hanseníase associada a linfoma não Hodgkin: relato de caso / Leprossy associated with non-Hodgkin's lymphoma: a case report

Os autores relatam o caso de paciente do sexo feminino, 55 anos de idade, que cinco meses após o dignóstico de linfoma não Hodgkin de baixo grau apresentou lesões de placas eritematovioláceas, infiltradas, com alteração de sensibilidade na porção inferior de coxa direita. A histopatologia mostrou infiltrado linfo-histiocitário na derme em arranjo granulomatoso, contendo bacilos álcoolacidorresistentes. O diagnóstico foi de hanseníase dimorfa associada a linfoma não Hodgkin. O objetivo deste artifo é relatar a raridade do curso paralelo das duas doenças que têm em comum a alteração do estado imunológico

Distribution of lymphocytes with interleukin-2 receptors (TAC antigens) in reactive lymphoproliferative processes, Hodgkin's disease, and non-Hodgkin's lymphomas. An immunohistologic study of 300 cases.

The authors investigated the distribution of interleukin-2 receptors (TAC antigen) in the lymph nodes of 300 patients with lymphoproliferative disorders. They used fresh-frozen sections to evaluate a possible correlation between the immunophenotype of specific lymphoid disorders and the presence or absence of TAC expression and to determine whether the TAC positivity of lymphoid cells contributes to the characterization of lymphoproliferative processes. All of the cases had previously been studied with a large screening panel of monoclonal antibodies and polyclonal antisera. Among 85 patients with a variety of benign reactive processes, the lymph nodes from 47 contained TAC-bearing lymphocytes in various patterns of distribution. Of 41 patients with Hodgkin's disease, 37 had TAC-bearing lymphocytes. Of 26 B-cell, well-differentiated lymphocytic lymphomas (WDL), 14 were diffusely TAC-positive and one had TAC-bearing cells in random distribution. Six cases of intermediate lymphocytic lymphoma were also studied, and three showed randomly distributed TAC-bearing lymphocytes. Of 19 patients with follicular or follicular and diffuse, poorly differentiated lymphocytic (PDL) lymphoma, 14 were TAC-positive. All 3 diffuse PDL lymphomas studied were TAC-negative. Among 23 cases of B-cell and 5 cases of T-cell mixed cell lymphoma, 15 and three, respectively, had TAC-positive lymphocytes. Of 39 large cell lymphomas (B-cell, 33; T-cell, 6), 14 were TAC-positive. All 13 cases of hairy cell leukemia were diffusely positive. Of 23 T-lymphoblastic lymphomas, only 1 showed positive TAC reactivity, which was focal. Of 5 cases of cutaneous T-cell lymphoma, 2 had TAC-bearing lymphocytes. Our study indicates that the TAC antigen is not lineage-specific, and that it may be expressed by lymphoid cells regardless of their phenotype.
