Pleomorphic adenoma is a benign tumor found rarely in the breast but commonly in the salivary gland. Unlike the salivary gland variant management guidelines are poorly defined in the breast. We describe the first case of pleomorphic adenoma of the breast that has recurred for the second time following previous surgical excisions, and review the available literature. Due to the risk of recurrence and malignant transformation, we recommend complete excision of the lesion with a cuff of normal tissue, as is the practice in the salivary gland. Clinicians should be aware of the condition, as preoperative diagnosis will facilitate adequate surgery. Patients should be informed about the risk of recurrence. We recommend follow-up for at least a period of 5 years with yearly clinical examinations.

(1) : Salivary gland tumors (SGTs) are a rare and diverse group of neoplasms arising in the parotid, submandibular, sublingual, and minor salivary glands distributed throughout the upper aerodigestive tract. Given the rarity and complexity of MSGTs, understanding their epidemiology across diverse populations is crucial for improving diagnostic and therapeutic strategies. (2) : A retrospective analysis involving 45 patients diagnosed with malignant salivary gland tumors and treated with curative intention between 1 July 2016 and 1 July 2021 in a tertiary academic hospital was performed.

Pleomorphic adenoma of the lacrimal gland (PALG) is a benign neoplasm typically presenting with gradual, painless globe displacement and/or lid swelling. We report an atypical case of PALG in a 53-year old male presenting acutely, mimicking orbital cellulitis. Imaging demonstrated an extraconal rim-enhancing soft-tissue lesion medial to the left lacrimal gland, involving superior rectus and levator palpebrae superioris.

A lipoblastoma is a benign tumor of adipocytes originating from embryonic white fat and occurs in the pediatric population. Congenital lipoblastomas, however, are rare, and the incidence of these tumors in neonates is unknown. Due to their rare presentation, congenital oral lipoblastomas can, firstly, pose diagnostic challenges for the pediatrician and must be differentiated from the more commonly seen oral lesions in the newborn and other rare malignant growths.

Although pleomorphic adenomas of the salivary glands are benign tumors, they can metastasize to distant organs without evidence of malignant transformation. We describe FDG PET/CT finding in a case of metastasizing pleomorphic adenoma in the right ilium occurring 22 years after initial surgical resection of a lip pleomorphic adenoma. On FDG PET/CT, the iliac metastasis appeared as an expansile osteolytic lesion with heterogeneous activity.
