ABSTRACT
OBJECTIVE: Triple negative breast cancer (TNBC), despite being the uncommon subtype, contributes a major portion to mortality and associated with poor prognosis. The purpose of this study was to evaluate the cytological criteria for the diagnosis of TNBC through fine-needle aspiration cytology (FNAC). MATERIAL AND METHOD: Clinical, cytological, histological, and immunohistochemical (IHC) data of 256 patients were evaluated, and patient were classified as TNBC and non-TNBC phenotype by IHC. All cytological specimens were reviewed for 12 criteria: cellularity, tubule/gland formation, syncytial clusters, large bare nuclei, nuclear atypia, chromatin pattern, cell borders, nucleolus, cytoplasm, lymphocytic infiltrate, calcification, and necrosis. The Fischer's exact test was used to show test association. RESULT: Out of 256 patients, 82 patients were TNBC, and 174 patients were non-TNBC. TNBC phenotype showed statistically significant association to cellularity, tubule/gland formation, syncytial cluster formation, bare nuclei, nuclear atypia, cell borders, lymphocyte infiltration, and necrosis. CONCLUSION: FNAC can be helpful in making diagnosis of TNBC and along with ER, PR, HER2 characterization, helpful in planning treatment strategy, saving time, manpower, and resources in the patient management.
ABSTRACT
Rosai-Dorfman disease is a rare histiocytic proliferative disorder with a distinctive microscopic appearance. Patients usually present with nonspecific symptoms and massive cervical lymphadenopathy. Exclusive involvement of intra-abdominal lymph nodes is unusual and presentation mimicking Wilkie's syndrome due to compression of the third part of the duodenum by enlarged retroduodenal lymph nodes is rare. This entity should be included in the differential diagnosis with infectious, granulomatous and malignant causes of intra-abdominal lymphadenopathy. We highlight an uncommon presentation and discuss the challenges in the diagnosis and management of Rosai-Dorfman disease.
