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...

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...

Adrenal lesions: Common findings and pitfalls on 18F-FDG PET/CT

Adrenal lesions are commonly observed during 18F-FDG PET/CT studies. Although, most of these lesions are considered benign, an important consideration in oncologic patients is metastasis. Benign lesions, such as adenomas usually present with low 18F-FDG uptake, although overlap with malignant lesions exist and clear SUV cut-off for distinguishing adrenal adenomas has not b...

اهمیت و کاربرد انواع مدل‌های موشی در تحقیقات سرطان: راهنمایی‌هایی در انتخاب بهترین مدل

Mice are the preferred model organisms in tumor and cancer research, concerning tumor biology (initiation, progression, and metastasis) or developing and screening the potential therapeutics. Different murine models including genetically engineered mice (GEM), xenografts, and chemical models may be used for this purpose. By reviewing the most recent scientific reports and publications, in the c...
