ABSTRACT
Introduction: Fine-needle aspiration cytology (FNAC) is often used as a screening tool. Cytopathologist should be aware of various mimickers of the malignancy. One of these is infarction of benign breast lesions. Careful examination of cytomorphological features will avoid the misdiagnosis of malignancy in such cases. Material and Methods: Six cases were diagnosed as benign breast lesion for 4 years and 5 months in our newly established tertiary referral center. Histopathology follow-up was available in one case. Results: Of six cases, three cases (50%) were reported as fibroadenoma with infarction, two cases (33%) as benign breast lesion with infarction favor fibroadenoma, and one as breast lesion with infarction favor phyllodes tumor in view of recurrence. Most were in the second or third decade of their life. All cases showed dyscohesive cells with pyknotic nuclei. Monolayered sheets of necrotic cells were seen in the four cases (66%). Viable cells were seen in four cases. Conclusions: FNAC provides a rapid and accurate diagnosis of benign breast lesions with infarction in the hands of experienced pathologists who can help in better patient care. Small-sized uniform pyknotic nuclei of dyscohesive cells and regular nuclear membranes help to differentiate them from inflammatory and malignant lesions.
ABSTRACT
Schwannomas are benign peripheral nerve sheath tumours that may occur throughout the body. They rarely occur in the nasal cavity. Paranasal schawannomas are uncommon lesions, representing less than 4% of all head and neck schawannomas. Here we report a case of sinonasal schwannoma in a 35-year-old man who presented with a history of nasal blockage since two years. The mass was removed successfully without any postoperative complication and there was no recurrence within a year of follow up.
