Cytologic features of a functioning parathyroid carcinoma: a case report
Acta Cytologica
|September 1, 1982
Summary
Cytologic examination of a functioning parathyroid carcinoma revealed highly cellular smears with numerous dissociated cells. Key findings include marked nuclear size variation, giant nuclei, and atypical clear cells, aiding differential diagnosis.
Area of Science:
- Cytopathology
- Endocrinology
- Surgical Pathology
Background:
- Parathyroid carcinoma is a rare endocrine malignancy.
- Fine needle aspiration (FNA) is a crucial diagnostic tool.
- Understanding cytologic features aids in differentiating benign from malignant parathyroid lesions.
Observation:
- The FNA smears were highly cellular, showing a significant number of dissociated single cells.
- These cells exhibited scant cytoplasm and marked nuclear size variation, including giant nuclei with prominent nucleoli.
- Atypical cell clusters with variable nuclear features and clear cells, often arranged in a palisading pattern along vascular septa, were also observed.
Findings:
- The cytologic presentation is characterized by high cellularity and pleomorphism.
- Distinctive features include dissociated atypical cells and clear cells with specific architectural arrangements.
- These findings are critical for the diagnosis of functioning parathyroid carcinoma.
Implications:
- Accurate cytologic diagnosis of parathyroid carcinoma is essential for appropriate patient management.
- Recognition of these specific cytologic features can guide surgical intervention and treatment planning.
- This case highlights the utility of FNA in diagnosing rare endocrine malignancies.
