Diagnostic Pitfalls in Aspiration Biopsy Cytology of Papillary Breast Lesions.

Diagnostic pitfalls of pilomatricoma on fine needle aspiration cytology

Pilomatricoma is a benign skin adnexal tumour usually seen in the head and neck region of children and young adults. It is underrecognized on cytology, resulting in the overdiagnosis of malignancy. We bring forth a case report of a slow growing nodular swelling in a 10-year-old female child, which was misdiagnosed on Fine Needle Aspiration Cytology (FNAC) as a malignant neoplasm and found to be...

Needle Core Biopsy Should Replace Fine Needle Aspiration Cytology in Breast Lesions Diagnosis

Nodular Fasciitis – Fine Needle Aspiration Cytology Diagnosis and Its Pitfalls, with Review of Literature

Background and Objective: Nodular fasciitis (NF) is a self-limiting, transient neoplasm composed of fibroblasts and myofibroblasts. Since it regresses spontaneously, diagnosis by fine needle aspiration (FNA) cytology plays a major role in its management. Methods: We present a series of 8 cases with either FNA or biopsy diagnosis of NF, and study the major...

Hurthle cells in fine needle aspiration cytology of the thyroid: a potential diagnostic dilemma?

Hurthle cells are not uncommonly encountered in thyroid fine needle aspiration cytology (FNAC) smears. They are easily recognized by their distinct cytomorphology in cytological preparations, i.e. large, polygonal cells displaying uniform, rounded nuclei, often prominent nucleoli and abundant granular cytoplasm. Hurthle cells can be seen in both non-neoplastic and neoplastic thyroid lesions whi...

Sub-classification of Breast Masses by Fine Needle Aspiration Cytology.

OBJECTIVE The aim of this study is to evaluate the accuracy of sub-classification of breast diseases using Fine Needle Aspiration cytology (FNAC). MATERIALS AND METHODS A one-year prospective study of 180 consecutive patients with palpable breast lesions who underwent FNAC and subsequently open surgical biopsy for histological confirmation. FNAC was used to sub-classify breast lesions and the...
