Utility of Insulinoma-Associated Protein 1 (INSM1) and Mucin 2 (MUC2) Immunohistochemistry in the Distinction of Endocrine Mucin-Producing Sweat Gland Carcinoma From Morphologic Mimics.

Am J Dermatopathol 2021 Jun 2. Epub 2021 Jun 2.

Department of Pathology, Brigham and Women's Hospital and Harvard Medical School, Boston, MA.

Abstract: Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare low-grade adnexal malignancy with a predilection for the eyelids of elderly White women, which is associated with invasive mucinous carcinoma with endocrine features in one-third of cases. EMPSGC is characterized by the presence of neuroendocrine differentiation and mucin production. However, EMPSGC displays a variety of architectural patterns including solid, cribriform, papillary, and cystic growth. Read More

Agger nasi mucocele cause nasolacrimal duct obstruction and chronic dacryocystitis: clinical profile, management and outcome.

BMJ Case Rep 2021 May 24;14(5). Epub 2021 May 24.

Department of Neurosciences, Faculty of Medicine and Surgery, University of Padova, Padova, Italy.

Synchronous pleomorphic adenoma in the infratemporal fossa and contralateral submandibular gland and endoscopic removal.

BMJ Case Rep 2021 May 21;14(5). Epub 2021 May 21.

Department of ENT and Head and Neck Surgery, Apollo Specialty Cancer Hospital, Chennai, Tamil Nadu, India.

The objective of this article is to elucidate on our experience with the first case reported in the literature of a synchronous presentation of pleomorphic adenoma (PA) in infratemporal fossa as well as the contralateral submandibular gland. PA most commonly arises from the major salivary glands but has also been reported to arise from minor salivary glands in unusual sites such as the nasal septum, main stem bronchus, trachea, lacrimal gland, external auditory canal, etc. However, it seldom involves the infratemporal fossa and extremely few cases are reported in the literature and coexistent contralateral synchronous PA is nowhere reported in literature.

Mascara-induced nasolacrimal duct obstruction.

BMJ Case Rep 2021 May 7;14(5). Epub 2021 May 7.

Department of Ophthalmology, Addenbrooke's Hospital, Cambridge, UK.

A 35-year-old woman underwent left external dacryocystorhinostomy (DCR) following a recent bout of left acute dacryocystitis. She had a right DCR 14 years earlier. Her relatively young age of presentation prompted suspicion of secondary nasolacrimal duct obstruction and, although the left lacrimal sac appeared macroscopically normal peroperatively, a lacrimal sac biopsy was taken.

Identification of patient benefit from proton beam therapy in brain tumour patients based on dosimetric and NTCP analyses.

Radiother Oncol 2021 Apr 17;160:69-77. Epub 2021 Apr 17.

OncoRay - National Center for Radiation Research in Oncology, Faculty of Medicine and University Hospital Carl Gustav Carus, Technische Universität Dresden, Helmholtz-Zentrum Dresden - Rossendorf, Germany; German Cancer Consortium (DKTK), partner site Dresden, and German Cancer Research Center (DKFZ), Heidelberg, Germany; Department of Radiotherapy and Radiation Oncology, Faculty of Medicine and University Hospital Carl Gustav Carus, Technische Universität Dresden, Dresden, Germany. Electronic address:

Background: The limited availability of proton beam therapy (PBT) requires individual treatment selection strategies, such as the model-based approach. In this study, we assessed the dosimetric benefit of PBT compared to photon therapy (XRT), analysed the corresponding changes in normal tissue complication probability (NTCP) on a variety of available models, and illustrated model-based patient selection in an in-silico study for patients with brain tumours.

Methods: For 92 patients treated at two PBT centres, volumetric modulated arc therapy treatment plans were retrospectively created for comparison with the clinically applied PBT plans. Read More

Masses of the Lacrimal Gland: Evaluation and Treatment.

J Neurol Surg B Skull Base 2021 Feb 18;82(1):100-106. Epub 2021 Feb 18.

Department of Ophthalmology, Duke University Medical Center, Durham, North Carolina, United States.

Lacrimal gland lesions account for approximately 9 to 10% of all biopsied orbital masses. Potential causes include nongranulomatous and granulomatous inflammation, autoimmune disease, lymphoproliferative disorders, benign epithelial proliferation, malignant neoplasia, and metastatic disease. Inflammatory lesions and lymphoproliferative disorders are the most common and may be unilateral or bilateral; they may also be localized to the orbit or associated with systemic disease. Read More

Surgical and Ophthalmologic Outcomes of Reconstruction in Patients Treated With Eye-Sparing Surgery and Radiation Therapy for Tumors of the Lacrimal Drainage Apparatus.

Ann Plast Surg 2021 03;86(3):292-297

From the Department of Plastic Surgery, The University of Texas MD Anderson Cancer Center, Houston, TX.

Introduction: Tumors involving the lacrimal drainage apparatus can be effectively treated with oncologic eye-sparing resection, immediate reconstruction, and adjuvant radiation. The extirpative technique is well described, whereas the reconstructive approach and outcomes are limited and largely anecdotal. The present study describes the largest series in the literature evaluating outcomes after reconstruction after globe-preserving oncologic resection. Read More

Lacrimal gland pleomorphic adenoma with extensive necrosis.

Orbit 2021 Jan 6:1-4. Epub 2021 Jan 6.

Orbital, Plastic and Lacrimal Clinic, Royal Victorian Eye and Ear Hospital, East Melbourne, Australia.

Lacrimal gland pleomorphic adenomas (LGPA) are benign mixed tumors. Diagnosis is based on clinical and radiological findings which usually prompts complete excision of the lesion to minimise recurrence and a cumulative risk of malignant transformation. Necrosis in pleomorphic adenoma has been rarely reported in salivary gland PA, either spontaneously or due to iatrogenic interventions. Read More

Primary Pituitary Adenoid Cystic Carcinoma: A Rare Salivary Gland-Like Tumor in the Sella.

Head Neck Pathol 2021 Jan 4. Epub 2021 Jan 4.

Department of Neurosurgery, Kurume University School of Medicine, 67 Asahimachi, Kurume, Fukuoka, 830-0011, Japan.

Adenoid cystic carcinoma (ACC) is a tumor of the exocrine glands that originates primarily from the minor and major salivary glands, nasopharynx, and lacrimal glands. ACC grows slowly but is locally aggressive and prone to recurrence. It is uncommon for ACCs to develop in the pituitary gland as a primary tumor. Read More

Using patient-specific bolus for pencil beam scanning proton treatment of periorbital disease.

J Appl Clin Med Phys 2021 Jan 24;22(1):203-209. Epub 2020 Dec 24.

New York Proton Center, New York, NY, USA.

Purpose: A unique mantle cell lymphoma case with bilateral periorbital disease unresponsive to chemotherapy and with dosimetry not conducive to electron therapy was treated with pencil beam scanning (PBS) proton therapy. This patient presented treatment planning challenges due to the thin target, immediately adjacent organs at risk (OAR), and nonconformal orbital surface anatomy. Therefore, we developed a patient-specific bolus and hypothesized that it would provide superior setup robustness, dose uniformity and dose conformity. Read More

BMC Ophthalmol 2020 Dec 10;20(1):486. Epub 2020 Dec 10.

Department of Ophthalmology, Chang Gung Memorial Hospital, No. 6, West section, Chia-Pu RoadPu-Zih City, Chia-Yi County, Taiwan.

Background: Chorioretinal fold (CFs) is a rare condition resulting from undulations in the choriocapillaris, Bruch's membrane, retinal pigment epithelium and occasionally neurosensory retina. It can be idiopathic or due to different etiologies. The use of spectral-domain optical coherence tomography (SD-OCT) has increased the diagnosis of CFs and helped in differentiation from other etiologies. Read More
