Anaplastic large cell lymphoma presenting as sternal swelling

Lymphomas involving the sternum are very rare. We report a case of lymphoma presenting as lytic sternal lesion. A 14-year-old girl presented with history of painless swelling of central chest (sternum) of 3 months duration. Fine needle aspiration cytology from the site revealed anaplastic large cell lymphoma. It was confirmed by histopathology and immunohistochemistry. She underwent treatment with chemotherapy but succumbed to her illness after six months of treatment.

Linfoma anaplásico de células grandes (lacg) asociado a implante mamario. Reporte de un caso y revisión de la literatura / Breast implant-associated anaplastic large cell lymphoma (bia-alcl). Description of one case diagnosed at the Buenos Aires British Hospital and literature review

Introducción El linfoma anaplásico de células grandes (lacg) asociado a implante mamario es una rara entidad descripta por primera vez en 1977. Hasta la actualidad, la Food and Drug Administration (fda) ha recibido 359 reportes de casos. Se manifiesta habitualmente como un seroma peri-protésico tardío o, menos frecuentemente, como una masa peri-capsular. En la mayoría de los casos, se asocia con implantes texturizados. Es fundamental el estudio citológico del seroma y la realización de cd30 en casos de sospecha diagnóstica. El tiempo medio desde la colocación del implante al desarrollo de la enfermedad es de 7 años a 10 años. Más del 80% de las pacientes se presentan en estadios tempranos, pudiendo ser tratadas solo con cirugía y sin requerir tratamientos adyuvantes. Objetivo El objetivo del presente trabajo es realizar el reporte de un caso de lacg diagnosticado y tratado en el Hospital Británico de Buenos Aires y realizar una revisión de la literatura

Introduction Breast implant-associated anaplastic large cell lymphoma (bia-alcl) is a rare T-cell lymphoma first described in 1977. As of February 1, 2017, the fda has received a total of 359 medical device reports. It typically occurrs in a delayed fluid collection around a textured implant. Specimens should be sent for cytology; essential to the diagnosis of bia-alcl is immunohistochemistry for cd30 cell surface protein. The median time from implant placement to diagnosis of alcl was 7 to 10 years. Disease localized to the capsule may be treated with surgery alone. Objective In this report we describe our experience with one case of bia-alcl diagnosed at the Buenos Aires British Hospital and we perform a review of the literature.

A Case of Primary Cutaneous Anaplastic Large Cell Lymphoma Mimmicking Keratoacanthoma / 대한피부과학회지

Pseudoepitheliomatous hyperplasia with a massive neutrophil infiltrate associated with primary cutaneous anaplastic large cell lymphoma has been rarely reported. Herein we report on a 33-year-old man who presented with multiple asymptomatic erythematous walnut-sized rapidly growing tumors on the axilla, trunk and left inguinal area for 1 month. The histopathologic features showed a keratoacanthoma-like epithelial hyperplasia in the epidermis and several large atypical lymphoid cells with nuclear plemorphism and abundant cytoplasm in the dermis. The atypical cells were obscured by a rich infiltrate of neutrophils and some eosionophils. Immunohistochemical studies confirmed the majority of the large anaplastic cells in the dermis were CD30+ cells. In addition, the expressions of anaplastic lymphoma kinase (ALK) and epithelial membrane antigen (EMA) were negative. There was no evidence of extracutaneous involvement. The patient was diagnosed with primary cutaneous anaplastic large cell lymphoma (ALCL) and he was treated with low dose methotrexate (15 mg/week). We think that this case was challenging both clinically and histologically.

A Case of Primary Cutaneous Anaplastic Large Cell Lymphoma with Extensive Inflammatory Cell Infiltration / 대한피부과학회지

Primary cutaneous anaplastic large cell lymphoma (ALCL) is composed of large cells with anaplastic, pleomorphic cytomorphology and the expression of the CD30 antigen by the majority (more than 75%) of tumor cells. Recently some variants of ALCL with extensive inflammatory cell infiltration have been reported. A 34-year-old male presented with multiple tumors over the arm, groin, and legs. The tumors of the right groin showed ulceration and purulent discharge. The biopsy specimens revealed extensive infiltrate of large atypical lymphoid cells with mixed inflammatory cells consisting of numerous eosinophils and neutrophils. Immunohistochemical staining was positive for CD3, CD4, and CD30. TCR-gamma gene rearrangement was detected. There was no evidence of extracutaneous involvement. We report a case of primary cutaneous ALCL, associated with marked inflammatory cell infiltration. Diagnosis in such cases is challenging because the large atypical lymphoid cells may be easily obscured by the massive infiltrate of eosinophils and neutrophils.

A Case of Primary Cutaneous CD30+/ALK- Anaplastic Large Cell Lymphoma / 대한피부과학회지

Primary cutaneous CD30(Ki-1) positive anaplastic large cell lymphoma(ALCL) is a rare subset of cutaneous lymphoma, with a much better prognosis. ALCL is a heterogeneous process that may have a T-cell, B-cell, or indeterminant(null) phenotype and which may or may not express the anaplastic lymphoma kinase(ALK) oncoprotein. We report a case of ALCL in a 72 year old man. About 4 months ago, multiple erythematous firm ulcerative mass and satellite nodules developed on the right lower leg. The skin lesions rapidly increased in number and size. Some lesions became painful and centrally ulcered. The histologic findings showed a diffuse infiltrate of large lymphocytes with large nuclei, prominent and multiple nucleoli, and ample cytoplasm. Immunohistochemical stainings for CD30, CD5 were positive but stainings for LCA, CD3, CD45RO, CD20, cytokeratin, EMA, and ALK were negative. Therefore, we diagnosed our case as CD 30+/ALK- ALCL.
