Diagnosis of two distinct malignancies in a single sample is rare. Here we report a case of lung adenocarcinoma metastasized to a supraclavicular lymph node which was concomitantly diagnosed with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) using ultrasound-guided fine needle aspiration biopsy (US-FNA) sample.A 62-year-old Caucasian male presented with cough and bloody sputum. US-FNA of a supraclavicular lymph node showed two distinct cell populations and, based on morphological examination and immunohistochemical staining of the FNA cell block slides, diagnosed with CLL/SLL and metastatic lung adenocarcinoma. Flow cytometric analysis of peripheral blood supported the diagnosis of CLL/SLL. To our knowledge, this is a rarely reported cytology case in which metastatic lung adenocarcinoma is concurrently diagnosed with CLL/SLL in a single lymph node and can be diagnosed based an FNA sample.

Sydney System

<b><i>Introduction:</i></b> The Sydney system proposal for the study and reporting of lymphadenopathy by fine-needle aspiration (FNA) constitutes one of the first attempts to standardize this procedure. Here, we review its applicability. <b><i>Materials and Methods:</i></b> A retrospective study in which all ultrasound-guided FNAs (USFNAs) of superficial lymphadenopathy (palpable or not) performed by interventional pathologists in 2 specialized hospital centers were quantified over 2 years. The procedure was systematized, and the diagnoses were reclassified according to the Sydney system categories. <b><i>Results:</i></b> We analyzed 363 USFNAs of lymphadenopathies. The distribution of cases by categories was as follows: insufficient (<i>n</i> = 13; 3.58%), benign (<i>n</i> = 208; 57.30%), atypia of uncertain significance (<i>n</i> = 7; 1.93%), suspicious (<i>n</i> = 21; 5.79), and malignant (<i>n</i> = 114; 31.40%). The risks of malignancy calculated for categories I, II, III, IV, and V were 27%, 3%, 50%, 100%, and 100%, respectively. <b><i>Conclusion:</i></b> The implementation of the Sydney system allows the systematization and standardization of the lymph node FNA methodology, with increased efficacy and efficiency. Assimilating the recommendations enables the qualification of the diagnostic procedure.

Transgastric Approach

Sarcina ventriculi is a rare gram-positive coccus increasingly reported in patients with a history of delayed gastric emptying or gastric outlet obstruction and is sometimes seen in association with emphysematous gastritis and perforation. We report a case of a 67-year-old male who presented with epigastric pain. CT imaging and cholangiopancreatography were concerning for pancreatic neoplasia. Upper endoscopic ultrasound-guided fine needle aspiration cytology of a perigastric lymph node confirmed metastatic adenocarcinoma of pancreatic origin, and cocci arranged in a tetrad fashions characteristic of Sarcina ventriculi were noted. To our knowledge, this is the first reported case of Sarcina ventriculi in an FNA of metastatic pancreatic carcinoma in a perigastric lymph node. These organisms likely represent carry-through contaminants from the transgastric approach of the endoscopic FNA.
