Summary
Sclerosing Polycystic Adenosis (SPA), a rare benign salivary gland tumor, can mimic malignancy on imaging and cytology. Histological confirmation is crucial for accurate diagnosis of this parotid gland neoplasm.
Area of Science:
- Head and Neck Pathology
- Diagnostic Imaging
- Cytopathology
Background:
- Salivary gland neoplasms predominantly occur in the parotid gland, with most being benign.
- Sclerosing Polycystic Adenosis (SPA) is a rare, newly described benign entity affecting salivary glands.
Observation:
- A 55-year-old patient presented with a parotid gland lesion suspicious for malignancy.
- Diagnostic work-up included Magnetic Resonance Imaging (MRI) and Fine Needle Aspiration Cytology (FNAC).
- Both MRI and FNAC findings mimicked a malignant tumor, despite SPA's benign nature.
Findings:
- The cytological and imaging features of SPA can be misleading, mimicking malignant salivary gland tumors.
- Histological examination is essential for definitive diagnosis and to rule out malignancy.
Implications:
- This case highlights the diagnostic challenges posed by SPA.
- Emphasizes the critical role of histopathology in confirming the diagnosis of parotid gland lesions, especially when imaging and cytology are equivocal.
- Underscores the need for awareness of rare entities like SPA in differential diagnosis.
