An 80-year-old woman presented with a mass in her left parotid region. An ultrasound-guided core biopsy showed sebaceous glands with lymphoplasmacytic infiltration. Magnetic resonance imaging displayed a well-circumscribed lesion within the left parotid gland. The mass was completely excised, and the patient made a full recovery. Sebaceous lymphadenomas of the salivary glands are rare, benign tumors that are effectively treated by complete excision. The challenge that these tumors present lies in their accurate diagnosis. Because of their histologic similarity to related malignant tumors, such as mucoepidermoid carcinomas and sebaceous lymphadenocarcinomas, misdiagnosis could lead to unnecessarily radical treatment. We highlight the need for careful clinical and histologic diagnosis in tumors of the salivary glands.

Salivary β2-Microglobulin, Na+, and Cortisol Levels, and Salivary Glands' Uptakes in Sialoscintigraphy in Sjögren Disease.
J Clin Rheumatol
January 2025
Department of Radiology, Sannoh Hospital, Chiba-shi, Japan.
Objective: For early diagnosis and inquiry into the pathophysiology of Sjögren disease (SjD), salivary secretion and component levels, and salivary glands' uptakes in sialoscintigraphy were examined, in this cross-sectional study.
Methods: Patients who visited our hospital with suspected SjD between April 2016 and March 2020 were checked for unstimulated salivary secretion and β2-microglobulin, Na+, and cortisol levels in saliva. The patients who showed any abnormal salivary test results underwent sialoscintigraphy; the uptakes in the parotid, submandibular, and thyroid glands were compared using paired t test.
Utility of 3D double-echo steady-state with water excitation (3D-DESS-WE) in diagnosing intraparotid facial nerve schwannoma: A case report.

Differentiating intraparotid facial nerve schwannoma from other parotid tumors, particularly pleomorphic adenoma, is clinically crucial due to significant differences in treatment approaches. We report a case of a male patient in his 70s presenting with a left parotid mass. Magnetic Resonance Imaging (MRI) revealed a mass within the left parotid gland exhibiting the characteristic ``target sign''.

Department of Otorhinolaryngology Head and Neck Surgery, Beijing Tiantan Hospital, Capital Medical University, No. 119, South Fourth Ring Road West, Fengtai District, Beijing, 100070, China.
Background: This study aims to identify a pathogenic SDHD mutation associated with hereditary head and neck paraganglioma (HNPGL) in a Chinese family and to explore its implications for genetic counseling.
Methods: The study involved a family with 15 members spanning three generations. A 31-year-old patient (II-4) was diagnosed with a left parotid gland tumor and a right carotid body tumor, while both the father and elder sister had right carotid body tumors, and the third sister had bilateral carotid body tumors.
Periorbital Microcystic Adnexal Carcinoma With Distant Metastases.
Ophthalmic Plast Reconstr Surg
December 2024
Department of Ophthalmology, Liverpool Hospital, Liverpool, New South Wales.
Purpose: Microcystic adnexal carcinoma (MAC) is a locally aggressive adnexal carcinoma of the head and neck, which has a high tendency for recurrence. MAC rarely has distant metastasis, with only one previously reported case originating from the periorbital region. We present a patient with periorbital MAC with distant metastasis and a review of all reported patients with metastatic disease.

Patients with intermediate-risk thyroid cancers may undergo treatment with radioactive iodine-131 (I-131). They often undergo a pretreatment diagnostic iodine scan that typically shows areas of physiological uptake in the stomach, bladder, parotid glands as well as thyroid-remnant uptake and sites of metastatic disease. A 48-year-old woman with intermediate-risk papillary thyroid cancer with metastases to lateral compartment lymph nodes was found to have increased retention of iodine in the medial portion of her left orbit on the diagnostic scan.
