Enfermedad de Lhermitte-Duclos y síndrome de Cowden. Reporte de un caso / Lhermitte-Duclos Disease and Cowden Syndrome. A Case Report

Presentación del caso. Se trata de una paciente femenina de 45 años con antecedentes de hipertensión arterial y múltiples cirugías por cáncer, entre ellas, cáncer de tiroides, carcinoma de parótida, cáncer de mama y cáncer endometrial. De manera incidental se identificó una lesión en el hemisferio cerebeloso derecho en una tomografía de senos paranasales, que fue confirmada a través de una resonancia magnética cerebral. La lesión presentaba una apariencia estriada, característica de gangliocitoma displásico del cerebelo o enfermedad de Lhermitte-Duclos. Considerando los antecedentes de diversos tipos de cáncer y los criterios de diagnóstico propuestos por el Consorcio Internacional Cowden y la Red Nacional Integral del Cáncer, se estableció el diagnóstico de síndrome de Cowden que había pasado desapercibido hasta el momento. Intervención terapéutica. Posteriormente, la paciente fue hospitalizada debido al crecimiento de una masa metastásica en el hemicuello derecho con afectación del plexo braquial, adenopatías cervicales, infraclaviculares y axilares derechas. Evolución clínica. En la actualidad, se encuentra recibiendo tratamiento paliativo con el objetivo de controlar los síntomas y mejorar su calidad de vida, ya que expresó su negativa a someterse a una intervención quirúrgica de resección tumoral

Case presentation. The report is of a 45-year-old female patient with a history of high blood pressure and multiple surgeries for cancer, including thyroid cancer, parotid carcinoma, breast cancer, and endometrial cancer. Incidentally, a lesion in the right cerebellar hemisphere was identified in a tomography of the paranasal sinuses, which was later confirmed in a brain magnetic resonance. The lesion had a striated appearance, characteristic of dysplastic gangliocytoma of the cerebellum or Lhermitte-Duclos disease. Considering the history of various types of cancer and the diagnostic criteria proposed by the International Cowden Consortium and the National Comprehensive Cancer Network, the diagnosis of Cowden syndrome, which had gone unnoticed until now, was established. Treatment. Subsequently, the patient was hospitalized due to the growth of a metastatic mass in the right hemicollar with involvement of the brachial plexus, cervical, infraclavicular, and right axillary lymph nodes. Outcome. She is receiving palliative treatment to control the symptoms and improve her quality of life, since she expressed her refusal to undergo tumor resection surgery

La enfermedad de Lhermitte-Duclos (ELD): Reporte del primer caso registrado en Paraguay con correlación radiológica-patológica

La enfermedad de Lhermitte-Duclos, o gangliocitoma displásico cerebeloso, es una rara entidad que se manifiesta como un proceso expansivo de crecimiento lento en la fosa posterior, específicamente en el cerebelo, con una patogenia no muy bien comprendida, que puede estar relacionada con anomalías congénitas y mutaciones del gen PTEN (fosfatasa y homólogo de tensina) sobre todo en la forma de presentación adulta. Los casos documentados de esta enfermedad son escasos, con alrededor de 230 registros en la literatura médica y una prevalencia menor a 1 por cada millón de personas. Presentamos el primer caso en Paraguay de Enfermedad de Lhermitte-Duclos en un paciente masculino de 44 años, sin antecedentes médicos o familiares relevantes, que fue intervenido quirúrgicamente por proceso expansivo de fosa posterior, con hallazgos característicos en la resonancia magnética, que permitió sospechar preoperatoriamente de la enfermedad, con diagnóstico diferencial de meduloblastoma, debido a restricciones observadas en la secuencia de Difusión. La resección fue completa con adecuada evolución y sin recaídas del proceso.

Lhermitte-Duclos disease, or cerebellar dysplastic gangliocytoma, is a rare entity that manifests as a slow-growing expansive process in the posterior fossa, specifically in the cerebellum, with a pathogenesis that is not well understood, which may be related to congenital anomalies and PTEN gene mutations (phosphatase and tensin homologue), especially in the form of adult presentation. Documented cases of this disease are scarce, with around 230 records in the medical literature and a prevalence of less than 1 per million people. We present the first case in Paraguay of dysplastic gangliocytoma or Lhermitte-Duclos disease in a 44-year-old male patient, with no relevant medical or family history, who underwent surgery due to an expansive process in the posterior fossa, with characteristic findings on magnetic resonance, which allowed preoperative suspicion of the disease, with differential diagnosis of medulloblastoma, due to restrictions observed in the Diffusion sequence. The resection was complete with adequate evolution and without relapses of the process. Keywords: Lhermitte- Duclos; Gangliocytoma; dysplastic; cerebellar; neuroradiology.

Lhermitte-Duclos disease: A case report and literature review / 中南大学学报(医学版)

Lhermitte-Duclos disease (LDD) is a type of rare brain tumor located in posterior fossa. A patient with LDD located in the left cerebellum and vermis was admitted by the Department of Neurosurgery, Xiangya Hospital, Central South University. MRI scan showed slightly heterogeneous enhancement at the region close to vermis. The patient underwent partial resection on August 11, 2016 without postoperative chemoradiotherapy. The progress free survival was 11 months and the overall survival was 17 months. What the case reveals is that the partial resection is not beneficial to these patients with LDD as the residual lesion probably recurs in a short term after operation. The pathogenesis, diagnosis and treatment of LDD are explored and summarized in combination with relevant literature.

Cerebellar Dysplastic Gangliocytoma: Case Report

Lhermitte-Duclos disease (LDD), or cerebellar dysplastic gangliocytoma, is a rare type of cerebellar tumor, from unknown origin. Patients can be asymptomatic for several years, but there are usually imprecise neurological signs for long periods.

A Rare WHO Grade I Lesion of the Posterior Fossa with Recurrence Biological Behavior ­ Dysplastic Gangliocytoma of the Cerebellum: Case Report

Dysplastic gangliocytoma of the cerebellum (DGC) or Lhermitte-Duclos Disease is a rare lesion (World Health Organization [WHO] grade I) characterized by thickened folia and replacement of the internal granular layer by abnormal ganglion cells. More commonly, the compromised patients are young adults presenting ataxia, seizures, obstructive hydrocephalus, and increased intracranial pressure. Dysplastic gangliocytoma of the cerebellum is intimately associated with Cowden syndrome, a hereditary disorder caused by a germline mutation in the PTEN tumor suppressor gene on chromosome 10q23. Large neurons of DCG show vesicular nuclei with prominent nucleoli. Expansion of the internal granular layer determines vacuolization of the molecular layer and white matter, which can be related to the bright stripes identified on T2-weighted magnetic resonance imaging. Herein, the authors report a female patient who developed long- time recurrence of DGC and discuss pathological findings and differential diagnosis of this rare cerebellar lesion.

Lhermitte-Duclos Disease and Cowden Syndrome: A Case Report and Literature Review

Lhermitte-Duclos disease (LDD), also known as dysplastic gangliocytoma of the cerebellum, is a rare, usually benign, slow-growing tumor, that commonly affects patients aged 30 to 50 years-old. The manifestations of dysplastic cerebellar gangliocytoma are nonspecific and are related both to the mass effect produced by its growth and to the location of the lesion. Cerebellar symptoms such as ataxia are often present. In 40% of cases, the tumor is associated with Cowden syndrome, which is part of a group ofgenetic disorders called polypoid hamartoma complex. In this case report, the patient presented expansive lesion in the posterior fossa, compatible with LDD, associated with macrocephaly. These findings are consideredmajor criteria for Cowden syndrome. When together, they confirm the diagnoses. To our knowledge, this is the first report of the association of LDD and Cowden syndrome in Brazil.

Assessing a Dysplastic Cerebellar Gangliocytoma (Lhermitte-Duclos Disease) with 7T MR Imaging

Lhermitte-Duclos disease (LDD; dysplastic cerebellar gangliocytoma) is a rare hamartomatous lesion of the cerebellar cortex and this was first described in 1920. LDD is considered to be part of the autosomal-dominant phacomatosis and cancer syndrome Cowden disease (CS). We examined the brain of a 46-year-old man, who displayed the manifestations of CS, with 7 Tesla (T) and 1.5T MRI and 1.5T MR spectroscopy (1H-MRS). We discuss the possible benefits of employing ultrahigh-field MRI for making the diagnosis of this rare lesion.

A case of Cowden's syndrome associated with Lhermitte-Duclos disease / 대한내과학회지

Cowden's disease, or multiple hamartoma syndrome, is an uncommon autosomal dominant condition characterized by mucocutaneous lesions and systemic malignancies. Lhermitte-Duclos disease, or dysplastic gangliocytoma of the cerebellum, is a rare cerebellar lesion that can cause mass effects in the posterior fossa. It may occur sporadically, or in association with Cowden's syndrome. We report a case of Cowden's disease associated with Lhermitte-Duclos disease in a 49-year-old man who underwent a routine checkup

Enfermedad de Lhermitte-Duclos: Informe de un caso y revisión de la literatura / Lhermitte-Duclos disease: Case report and review of literature

Introducción. El gangliocitoma displásico del cerebelo fue descrito originalmente en 1920 por Lhermitte y Duelos, autores a quienes se les debe el epónimo de esta enfermedad. Es una entidad rara, caracterizada por ser una masa tumoral unilateral de la corteza cerebelosa, de crecimiento muy lento, que produce un aumento de la presión intracraneana. En 1991 Padberg y col. describieron la asociación de la enfermedad Lhermitte-Duclos y el síndrome de Cowden (SC). Aún no se ha comprendido completamente la biología molecular que asocia a estas enfermedades, sin embargo se ha comprobado en estudios modelos animales (ratones) mutaciones del gen homólogo de fosfatasa y tensina suprimido del cromosoma 10 (PTEN). Las imágenes de resonancia magnética son características de esta entidad, de tal manera que permiten hacer el diagnóstico preoperatorio sin la necesidad de estudios histopatológicos, permitiendo una evaluación y manejo neuroquirúrgico adecuados. Caso clínico. Se informa el caso de una mujer de 17 años con enfermedad de Lhermitte-Duclos del hemisferio cerebeloso derecho no asociado a SC, en quien el diagnóstico se estableció en el transoperatorio con improntas de la lesión cerebelosa. Conclusión. No existen publicaciones previas que describan las características cito lógicas de la lesión, y en este caso sí fue posible estudiarlas.

Introduction. Dysplastic cerebellar gangliocytoma was first described in 1920 by Lhermitte and Duelos, authors who gave their name to the entity. It is a rare condition, which is characterized by a very slowly growing unilateral tumor mass of the cerebellar cortex, producing increased intracranial pressure. In 1991 Padberg et al. described the association of Lhermitte-Duclos disease and Cowden syndrome. The relationship between these 2 entities has been associated with mutations of the phosphatase and tensin homolog deleted on chromosome (PTEN) gene. Magnetic resonance imaging findings are the hallmark of this entity, and the diagnosis is established without hystopathologic studies. Case report. We inform a case of a 17 years old girl with Lhermitte-Duclos of the right cerebellar hemisphere without Cowden syndrome.

A Case of Cowden Disease Associated with Lhermitte-Duclos Disease / 대한소화기내시경학회지

Cowden disease (CD), also known as 'multiple hamartoma syndrome', is a rare autosomal dominant disorder with a high risk of breast, thyroid, or genitourinary malignancies. Lhermitte-Duclos Disease (LDD) is believed to be a hamartomatous overgrowth of cerebellar ganglion cells and currently is considered to be a part of CD. However, the report of the association between LDD and CD has been very unusual. We have recently experienced a 53-year-old man with LDD who had acral keratosis of extremities, gastrointestinal polyposis, and multinodular goiter. To our knowledge, it is the second case of CD associated with LDD in Korea. We report it with a review of the literatures.

Lhermitte-Duclos Disease Associated with Cowden Disease

Lhermitte-Duclos disease, or dysplastic gangliocytoma of the cerebellum, is a peculiar hamartoma arising from the cerebellar cortex. Cowden disease, which is also termed as a multiple hamartoma-neoplasia syndrome, is an unusual autosomal dominant disorder characterized by mucocutaneous lesions, including facial papules, gingival papillomas, and acral keratoses. Other systemic hamartomas are frequently present, and there are high incidence of breast, thyroid, and genitourinary malignancies. Recently, it is accepted that Lhermitte-Duclos disease is a part of Cowden disease, a new phakomatosis. Recognition of this association has clinical significance, because diligent long-term follow-up monitoring of individuals with Lhermitte-Duclos disease and Cowden disease may lead to the early detection of malignancy.

Lhermitte-Duclos Disease in a Sudden Death: An autopsy case

Lhermitte-Duclos disease of the cerebellum manifests itself as a slowly growing mass formed by abnormal neurons that appear more malformative than tumoral. Although most cases show satisfactory clinical evolution, several cases, not recognized in life, died abruptly, usually from respiratory arrest. We recently experienced a 19 year old male, who died suddenly during alcohol drinking. At autopsy, the cerebellum revealed thickening of the folia over two limited areas. Microscopically, the lesion was characterized by proliferation of abnormal neuronal cells with excessive myelination of their axons, disappearance of Purkinie cells and greatly reduced white mater. Theories regarding the pathogenesis of Lhermitte-Duclos disease were reviewed and discussed.
