Schwannoma with Psammoma Body

We present a case of a 59-year-old male veteran with a chronic history of right foot soft-tissue mass that was causing pain in his shoes, but not functional or neurologic symptoms. Excision of the mass and pathologic evaluation resulted in multidisciplinary involvement and evaluation. In this example, the mass was found to be either an unusual schwannoma that happens to be psammoma body–rich or an unusual psammomatous melanocytic schwannoma that deviates from conventional examples, as a diagnostic consensus was unable to be reached. Schwannomas are an uncommon finding in the foot, and even more uncommon are those that contain psammoma bodies. Although rare, these tumors can be concerning for more systemic, life-altering diseases such as Carney complex, for which our patient refused genetic testing.

Acinic Cell Carcinoma-Papillary Cystic Variant with numerous psammoma body: A Case Report

Acinic cell carcinoma (ACC) is a rare, low-grade malignant salivary gland neoplasm.Parotid gland is the most common location reaching up to 90% of cases. Papillarycystic variant (PCV) is a much more seldom subtype of ACC. Proper diagnosis ofACC-PCV is only made on histopathology examination. The presence of psammomabody in salivary gland lesions is infrequent finding that may be confused with otherbenign or malignant lesions. The present case describes ACC-PCV in a 31-year-oldSaudi male patient referred to King Abdulaziz University Hospital as post superficialparotidectomy which the patient underwent 3 months ago. This case emphasizesthe importance of distinguishing between neoplastic and non-neoplastic lesions withnumerous psammoma bodies.Key words: papillary cystic acinic cell carcinoma–psammoma body–histopathology–parotid gland.
