Rethinking Retromandibular Vein Assessment in Parotid Tumors: Highlighting the Necessity of 3D Imaging.

Pleomorphic adenoma of parotid gland is the most frequently occurring benign tumour in salivary glands and involvement of superficial or deep lobe is determined in relation to the retromandibular vein on imaging. This case report discusses a 69-year-old female who had pleomorphic adenoma in superficial lobe of parotid gland but misinterpreted as involvement of both lobes on imaging when assessed in relation with retromandibular vein on an MRI. Although extensive literature is available on the anomalous variations in the relationship between the retromandibular vein and the facial nerve, no case reports have documented peritumoral nodule of the superficial lobe growing beneath the retromandibular vein and mimicking as a deep lobe lesion on radiological evaluation.

Cytology of micropapillary mucinous carcinoma: A case report of a clinically and genetically distinct breast carcinoma variant.

Micropapillary mucinous carcinoma (MPMC) is an uncommon histopathological variant of breast cancer accounting for approximately one-fifth of all mucinous breast carcinomas. In contrast to pure mucinous carcinoma, MPMC tends to affect younger women and is associated with decreased progression-free survival, higher nuclear grade, lymphovascular invasion, lymph node metastasis, and positive HER2 status. Typically MPMC histology shows micropapillary architecture with "hobnailing" of cells and reverse polarity.
