Cytologic diagnosis of metastatic malignant phyllodes tumor of the breast in pleural effusion

Abstract: A 54‐year‐old woman presented with a left breast mass, discovered 4 years ago but was static until 2 months before presentation, when it showed a rapid increase in size and became painful. Mammography showed a large lobulated mass with internal cystic components (BI‐RADS 4B). A biopsy was performed, followed by modified radical mastectomy. The histologic diagnosis was malignant phyllodes tumor (PT). The patient developed local recurrence 4 months later while on adjuvant radiotherapy and she had a salvage resec… Show more

“…A search of PubMed for publications focused on the distribution of malignant effusions published in the past two decades in the English language resulted in individual case reports, original studies consisting of relatively low number of malignant specimens, and limited reviews 2‐12 . To investigate how the incidence of different types of malignancy involving malignant effusions has changed, Dermawan et al conducted a study consisting of malignant pleural, peritoneal and pericardial effusions diagnosed during a 17‐year (2000‐2016) period.…”

“…However, in the context of pleural effusion, fluid cytology has the potential advantage of sampling exfoliated cells from the entire pleural cavity 5 . The diagnostic accuracy and yield of these two methods may vary according to the nature of pleural effusion, as small or mediastinal pleural lesions can be difficult to biopsy, 6 whereas tumor cells shed to pleural fluid may be scanty in sarcomas 7 . A direct comparison of the diagnostic accuracy and yield of these two methods, with respect to the underlying condition, is necessary for selecting the optimal mode of tissue acquisition.…”

“…5 The diagnostic accuracy and yield of these two methods may vary according to the nature of pleural effusion, as small or mediastinal pleural lesions can be difficult to biopsy, 6 whereas tumor cells shed to pleural fluid may be scanty in sarcomas. 7 A direct comparison of the diagnostic accuracy and yield of these two methods, with respect to the underlying condition, is necessary for selecting the optimal mode of tissue acquisition. In this study, we reviewed a large cohort of matched pleural effusion cytology and biopsy, compared the diagnostic concordance of these two methods, and further analyzed their accuracy by reviewing hospital disease coding confirmed with clinical, radiological, microbiological, serological, and /or pathological data.…”

“…Similar to carcinomas, tumor cells in sarcomas exfoliate into fluid filled body cavities and can be detected on cytology. 2 However, the incidence of sarcomas are relatively low compared to carcinomas, 4 and malignant sarcomatous effusions are far less often encountered than carcinomatous effusions in routine cytology practice. 3 Retroperitoneal liposarcomas not uncommonly extends to the peritoneal cavity, and are associated with a higher risk of peritoneal sarcomatosis than sarcomas of the extremities.…”
