ABSTRACT

Background Acute tubulointerstitial nephritis (ATIN) is a very rare paraneoplastic manifestation in patients with multiple myeloma (MM). It is an uncommon pattern of renal disease in such patients. Case presentation We report a case of an 82-year-old male who was admitted with acute kidney injury. Renal biopsy showed typical findings of light chain-associated ATIN with scattered inflammatory cells in the interstitium and associated active tubulitis. No other common manifestations of MM were present at the time of presentation, including hypercalcemia, hyperuricemia, proteinuria, bone pain or lytic bone lesions. Subsequent immunoassays revealed significant serum lambda light chain burden and Bence Jones protein in urine. Immunofluorescence demonstrated linear tubular basement membranes with positive staining for lambda light chain (3+). Electron microscopy (EM) further showed interstitial edema and inflammation. All the aforementioned findings are consistent with ATIN and supported the diagnosis of MM. Conclusions In conclusion, light chain-associated ATIN should be considered in the differential diagnosis of acute interstitial nephritis. Henceforth, serum free light chains as well as serum and urine protein electrophoresis should be included in the workup of such patients.

ABSTRACT

El diagnóstico diferencial de la macroglosia es amplio y puede estar en el contexto de una patología localizada o una enfermedad sistémica. Dentro de las enfermedades sistémicas que se manifiestan con macroglosia se describe la amiloidosis, caracterizada por un depósito irreversible de una proteína amorfa y fibrilar El compromiso de esta patología en el territorio de cabeza y cuello es infrecuente y su depósito en la lengua corresponde a menos del 9% de los casos. Se presenta el caso de un paciente que consultó por dolor en hemilengua derecha, disfagia y baja de peso. Se estudió inicialmente con exámenes de laboratorio y nasofibroscopía, sin hallazgos concluyentes. Dado persistencia de síntomas se realizó resonancia nuclear magnética (RM) que mostraba signos sugerentes de enfermedad de depósito, confirmándose mediante estudios histopatológicos una amiloidosis sistémica secundaria. El paciente fue derivado a hematología para completar estudio e iniciar el tratamiento. La amiloidosis sistémica es un diagnóstico infrecuente, que debe ser considerado por su mal pronóstico vital. El diagnóstico en etapas iniciales puede mejorar sustancialmente la sobrevida y calidad de vida de aquellos que padecen la enfermedad. Por lo anterior, es necesario completar un estudio acabado de la patología, apoyándose en métodos no invasivos como la RM.


The differential diagnosis of macroglossia is broad, and it may be present in the context of a localized pathology or a systemic disease. One of the systemic diseases that present macroglossia is amyloidosis, which is characterized by an irreversible deposit of an amorphous and fibrillar protein. The manifestation of this pathology in head and neck territory is infrequent, and its deposit in the tongue represents less than 9% of all types of amyloidosis. We present the case of a patient, who consulted with pain in the tongue, dysphagia, and weight loss. He was initially studied with laboratory tests and a nasofibroscopy with no conclusive findings. Given the persistence of symptoms, magnetic resonance imaging (MRI) was performed, showing signs of an infiltrative disease, which was confirmed as secondary systemic amyloidosis through histopathological studies. Given the above, the patient was referred to hematology to start treatment. Systemic amyloidosis is an uncommon diagnosis that should be suspected since it implies a poor vital prognosis. Moreover, an early diagnosis can substantially improve the survival rate and quality of life of those who suffer this disease. Therefore, a comprehensive study of this condition is needed, complementing with non-invasive methods such as MRI.

ABSTRACT

ABSTRACT Background Renal failure (RF) is a common complication in patients with newly diagnosed multiple myeloma (NDMM). Aim To evaluate the frequency of RF in NDMM patients, and the prognostic impact of its reversibility. Material and Methods A retrospective study evaluating demographic and clinical characteristics of 154 consecutive patients with NDMM was carried out. Estimated glomerular filtration rate (eGFR) was calculated at the beginning and at the end of the induction therapy. In addition, we evaluated renal responses (RR) according to the International Myeloma Working Group (IMWG) criteria. The induction regimen was based on thalidomide in all cases. Results Fifty-three patients had RF (34.4%). Complete renal response (RR) was achieved in 51%. Three years overall survival in patients without RF, with RF and complete RR, and patients with RF and any other RR, was 66, 47 and 13%, respectively. Median survival was 53, 27 and 6 months, respectively (p < 0.01). In the multivariate analysis, RF and hypercalcemia were independent predictors of a worse outcome. Conclusions Achieving a complete RR in patients with NDMM, is associated with a better survival.


Antecedentes La falla renal (FR) es una complicación frecuente en pacientes con mieloma múltiple (MM). Objetivo Evaluar la frecuencia de FR en pacientes con reciente diagnóstico de MM y determinar la importancia pronóstica de su reversibilidad. Material y Métodos Se realizó un estudio retrospectivo de 154 pacientes consecutivos con MM. La función renal se evaluó mediante la tasa estimada de filtración glomerular al inicio y final de la terapia de inducción. Además, evaluamos las respuestas renales (RR) de acuerdo con los criterios del International Myeloma Working Group (IMWG). El régimen de inducción se basó en talidomida en todos los casos. Resultados Cincuenta y tres pacientes presentaron FR (34,4%) al diagnóstico. La RR completa se logró en 51%. La sobrevida global (SG) a 3 años en pacientes sin FR, con FR y RR completa, y pacientes con FR y cualquier otra RR, fue de 66, 47 y 13%, respectivamente. La SG media fue de 53, 27 y 6 meses (p < 0,01), respectivamente. En el análisis multivariado, la FR y la hipercalcemia fueron factores independientes de menor sobrevida. Conclusiones Lograr una RR completa en pacientes con MM recién diagnosticado se asocia con una mejor sobrevida.

ABSTRACT

El mieloma múltiple es una enfermedad oncohematológica, que representa el 15% de las enfermedades hematológicas malignas. La edad media de aparición es entre los 65-70 años, siendo muy poco frecuente en pacientes jóvenes; 2% son menores de 40 años. Presentamos el caso de una mujer de 36 años con antecedente de tabaquismo de 20 paquetes año. Consultó por disnea asociada a signos de insuficiencia cardíaca derecha, anemia, proteinuria, elevación de reactantes de fase aguda y patrón sugestivo de restricción moderadamente grave en la espirometría y caída de la capacidad de difusión de monóxido de carbono (DLco). El ecocardiograma doppler evidenció dilatación de cavidades derechas y signos de hipertensión pulmonar que se confirmó con cateterismo cardiaco derecho. En busca de la etiología se arribó al diagnóstico de mieloma múltiple.


Multiple myeloma is a hematologic disease, which accounts for 15% of hematologic malignancies. The average age of onset is between 65-70 years and is very rare in young patients, as 2% are under 40 years old. We present a case of 36-year-old women with history of 20 pack years (p/y) smoking, who complaints of dyspnea associated with signs of right cardiac overload, anemia, proteinuria, elevated acute phase reactants and spirometry pattern suggestive of moderately-severe restriction and severe drop in diffusing capacity for carbon monoxide (DLCO). Echocardiogram evidence dilated right heart cavities and signs of pulmonary hypertension which is confirmed by right heart catheterization. In search of the etiology we arrive to the diagnosis of multiple myeloma.

ABSTRACT

Multiple Myeloma is a myeloproliferative disorder of plasma cells, which may be complicated with secondary amyloidosis. We report a 48 year old woman consulting to primary care for weight loss and malaise. An initial laboratory study revealed a hypogammaglobulinemia with a monoclonal component and lambda light chains. These results motivated her derivation to hematology: her serum calcium was 11.8 mg/dl, immunofluorescence showed a monoclonal component of lambda chains and urine Bence-Jones protein was positive. A bone marrow biopsy confirmed plasma cell infiltration. A Congo-red stain of a rectal biopsy was positive. The patient was treated with thalidomide, bortezomid and dexamethasone.

ABSTRACT

Abstract: Fusariosis is due to inhalation or direct contact with conidia. Clinical presentation depends on host's immunity and can be localized, focally invasive or disseminated. Given the severity of this infection and the possibility for the dermatologist to make an early diagnosis, we report six cases of patients with hematologic malignancies, who developed febrile neutropenia an skin lesions suggestive of cutaneous fusariosis. All patients had skin cultures showing growth of Fusarium solani complex, and they received amphotericin B and voriconazole. As this infection can quickly lead to death, dermatologists play a crucial role in diagnosing this disease.

ABSTRACT

There is an increased incidence of hematological malignancies, particularly non-Hodgkin lymphoma (NHL) in systemic lupus erythematosus (SLE). In contrast, the concurrence with Multiple Myeloma (MM) is very rare, and the possible pathogenetic mechanisms underlying this association remain unclear. We report two patients who developed MM 15 and four years after being diagnosed as having SLE.

ABSTRACT

Objetivou-se com o presente trabalho relatar um caso de mieloma múltiplo (MM) em uma cadela com apresentação clínica atípica de rigidez da musculatura facial. Foram realizados hemogramas seriados, exames bioquímicos, sumário de urina, sorologia para leishmaniose, radiografias de crânio, citologia de medula óssea e eletroforese de proteínas séricas. O infiltrado plasmocitário em medula óssea >20%, a gamopatia monoclonal e as lesões compatíveis com lise óssea, observados no mielograma, eletroforese de proteínas e exame radiográfico, respectivamente, foram determinantes para conclusão diagnóstica de MM. A doença pode ter uma apresentação clínica variável em cães e representar um desafio ao diagnóstico na clínica de animais de companhia, principalmente em áreas endêmicas de doenças infecciosas que se manifestam com apresentações clínicas e laboratoriais semelhantes.(AU)


This paper reports a case of multiple myeloma (MM) in a bitch with atypical clinical presentation of rigidity of the facial muscles. Hemogram, biochemical tests, urinalysis, serology for leishmaniasis, skull radiography, bone marrow cytology and serum protein electrophoresis were performed. The plasma cell infiltration in bone marrow was >20 %, the monoclonal gammopathy and lesions compatible with bone lysis observed in the myelogram, protein electrophoresis and radiographic examination respectively, were decisive for diagnostic conclusion of MM. The disease may have a variable clinical presentation in dogs and pose a challenge for diagnosis in the pet clinic, especially in endemic areas of infectious diseases that present with similar clinical and laboratory presentations.(AU)

ABSTRACT

Abstract The association between plasmacytomas and multiple myeloma (MM) is well-described, and in about one third of the cases of plasmacytoma the additional study will lead to the diagnosis of MM. The finding of plasmacytomas in the genital tract is extremely rare, with sparse cases described in the literature, and these cases pose a challenge regarding the optimal guidance and treatment. This paper describes a case of uterine extramedullary plasmacytoma in a 79-year-old woman with complaints of postmenopausal abnormal uterine bleeding. The complementary study led to the diagnosis of uterine plasmacytoma and, subsequently, of MM. Despite the unfavorable outcome of this case, we consider pertinent to report it because it constitutes a differential diagnosis to be taken into account in the approach of pelvic masses.


Resumo A associação entre plasmocitomas e mieloma múltiplo (MM) encontra-se bem demonstrada, e em cerca de um terço dos casos de plasmocitoma o estudo adicional conduzirá ao diagnóstico de MM. O achado de plasmocitomas no trato genital é extremamente raro, havendo um número muito limitado de casos descritos na literatura, o que dificulta concluir sobre a melhor forma de orientação e tratamento destes casos. O presente trabalho descreve um caso de plasmocitoma extramedular uterino em mulher de 79 anos estudada por queixas de hemorragia uterina anômala pós-menopáusica. O estudo complementar levou ao diagnóstico de plasmocitoma uterino e, posteriormente, de MM. Apesar do desfecho desfavorável do caso, consideramos pertinente o seu relato por se tratar de um diagnóstico diferencial a levar em consideração na abordagem de massas pélvicas.

ABSTRACT

El plasmocitoma extradural a nivel cervical es una de las patologías menos frecuentes dentro de los tumores extramedulares del mieloma múltiple; así mismo, es infrecuente que cause compresión medular o de las raíces nerviosas. Se presenta este caso por su gravedad y baja frecuencia en un paciente con diagnóstico de mieloma múltiple en tratamiento, que concurre con síntomas neurológicos (parestesia y paresia braquial bilateral) en la semana posterior a la cirugía de liberación meningorradicular y artrodesis cervical (C6-C7), en el mismo nivel de aparición de un plasmocitoma intracanal, extradural diagnosticado por resonancia magnética y confirmado con el resultado de la biopsia intraquirúrgica. Se ha publicado un caso similar al presentado, pero con la diferencia de que el paciente debutó con cuadriparesia. Se conoce también un caso de plasmocitoma originado en la médula espinal de la región torácica. En nuestro paciente, al igual que en un caso reportado con mieloma múltiple asintomático con manifestación primaria de plasmocitoma extramedular, la evolución de la enfermedad fue rápida, y el paciente falleció en menos de un año desde el diagnóstico. Nivel de Evidencia: IV.


Epidural plasmacytoma at the cervical spine is one of the less common extramedullary tumors in multiple myeloma. Likewise compression of the spinal cord or the nerve roots is uncommon. The following case is presented due to its rarity and severity. A patient diagnosed with and being treated for multiple myeloma presented with neurological symptoms (paresthesia and bilateral upper extremity weakness) a week after decompression and C6-C7 fusion, at the same level of an intracanal, epidural plasmacytoma detected by magnetic resonance and confirmed by intraoperative biopsy. A similar case was published, however it differs in that the patient presented with quadriplegia. There is also a reported case of plasmacytoma originating in the thoracic region of the spinal cord. In our patient, similar to the previously reported case of asymptomatic multiple myeloma with primary manifestation of extramedullary plasmacytoma, progression of the disease was rapid and the patient died less than one year from diagnosis. Level of Evidence: IV.

ABSTRACT

El plasmocitoma de la mama es muy infrecuente y en la mayoría de los casos aparece asociado a mieloma múltiple. Se describe una paciente de 42 años de edad con diagnóstico conocido de plasmocitoma solitario del cuello asociado a mieloma múltiple, que 11 meses después de alcanzada la remisión se presenta con una tumoración en la mama derecha sin manifestaciones sistémicas de mieloma. El estudio histológico e inmunohistoquímico del tumor confirmaron el diagnóstico de plasmocitoma. El diagnóstico diferencial en ocasiones es difícil y debe hacerse con tumores primarios y secundarios de la mama. El tratamiento de elección es la radioterapia local siempre que no existan manifestaciones sistémicas de la enfermedad subyacente(AU)


Breast plasmocytoma is infrequent and in most of the cases is associated to multiple myeloma. We describe a 42 year old woman with a diagnosis of solitary plasmocytoma of the neck associated to multiple myeloma that went into remission and eleven months later she presented a right breast lump which was confirmed by core biopsy and immunohistochemical study to be a plasmocytoma. Sometimes differential diagnosis is difficult and should be performed in primary and secondary breast tumours. The election treatment is radiotherapy if there are not manifestations of a subyacent sistemic disease(AU)

ABSTRACT

The aim of this study was to identify the risk factors associated with severe bacterial infection (SBI) in multiple myeloma (MM) patients during treatment with bortezomib-based regimens. A total of 98 patients with MM were evaluated during 427 treatment courses. SBI occurred in 57.1% (56/98) of the patients and during 19.0% (81/427) of the treatment courses. In the multivariate analysis for the factors associated with the development of SBI in each treatment course, poor performance status (Eastern Cooperative Oncology Group ≥ 2, P < 0.001), early course of therapy (≤ 2 courses, P < 0.001), and pretreatment lymphopenia (absolute lymphocyte count < 1.0 × 10(9)/L, P = 0.043) were confirmed as independent risk factors. The probability of developing SBI were 5.1%, 14.9%, 23.9% and 59.5% in courses with 0, 1, 2, and 3 risk factors, respectively (P < 0.001). In conclusion, we identified three pretreatment risk factors associated with SBI in each course of bortezomib treatment. Therefore, MM patients with these risk factors should be more closely monitored for the development of SBI during bortezomib-based treatment.

ABSTRACT

Abstract

Pegylated liposomal doxorubicin is an important antineoplastic agent with activity in a variety of solid tumors. It has a totally different profile of pharmacokinetics and toxicity compared with doxorubicin. It rarely causes side-effects like cardiotoxicity or hair loss, but frequently results in many kinds of mucocutaneous reactions, including palmar-plantar erythrodysesthesia, diffuse follicular rash, intertrigo-like eruption, new formation of melanotic macules, stomatitis and radiation recall dermatitis. We present a rare case of multiple myeloma who immediately developed serious stomatitis and esophatitis associated with minor palmar-plantar erythrodysesthesia after a single course of pegylated liposomal doxorubicin.

ABSTRACT

A hipoglicemia em um adulto aparentemente saudável é um achado raro na prática clínica que exige uma investigação exaustiva da causa. A identificação de glicemia plasmática diminuída associada a concentrações plasmáticas de insulina e peptídeo-C não suprimidos deverá levar à exclusão de causas raras de hipoglicemia, entre elas, doença das células betapancreáticas e hipoglicemia autoimune. Neste artigo, descrevemos dois casos de hipoglicemia associada a hiperinsulinismo endógeno, cujas causas são pouco habituais na prática clínica. A propósito desses casos clínicos revemos aspectos importantes de diagnósticos e tratamento da hipoglicemia no contexto de hiperinsulinismo endógeno.


Hypoglycemia in apparently healthy adults is a rare finding in clinical practice requiring a thorough investigation of the cause. During the investigation, identification of hypoglycemia associated with inappropriately high levels of insulin and C-peptide should prompt the exclusion of rare causes of hypoglycemia, including pancreatic islet-cells disease and autoimmune hypoglycemia. In this paper, we describe two cases of hypoglycemia associated with endogenous hyperinsulinism, whose causes are uncommon in clinical practice, and review important aspects of the diagnosis and treatment of hyperinsulinemic hypoglycemia.
