Polymorphous low-grade adenocarcinoma of the upper lip with metachronous myoepithelioma of the buccal mucosa

Examples of multiple minor salivary gland tumors, synchronous or metachronous, are uncommon. We report a patient who initially presented with polymorphous low-grade adenocarcinoma (PLGA) and subsequently with myoepithelioma. A 91-year-old white woman presented in 2009 with a 1-cm, firm, nontender, well-circumscribed nodule of the left side of the upper lip extending to the anterior buccal mucosa. Excisional biopsy revealed PLGA. While the margins were positive, further treatment was not recommended due to the patient's age. In 2011, the patient returned with a 1.5-cm, asymptomatic mass of the left buccal vestibule. Excision of the lesion revealed a circumscribed proliferation of epithelioid and plasmacytoid cells arranged in spherical or whorl-like islands and immersed in a mucinous stroma, consistent with myoepithelioma. The PLGA recurred 3 years after initial diagnosis. Excision was again associated with positive margins, and again no further treatment was recommended. A few months later, at a scheduled follow-up appointment, she presented with a painless nodule of the left upper lip, consistent with recurrent PLGA. One month later, the patient died of unrelated causes. We also present a literature review of multiple minor salivary gland tumors.

Here’s a summary of the most important stuff about our General Pathology (DDS 6253) course for Summer, 2021.

Syllabus
You can download a copy of the current syllabus here.

Objectives
General Pathology will give you a basic understanding of the foundational aspects of pathology, such as inflammation, tissue repair, and neoplasia. This will prepare you for the Systemic Pathology course given in the fall semester of the D2 year, as well as for your Oral Pathology course.

Director
The Course Director is Kristine Krafts, M.D. Please feel free to email me at [email protected] with any questions you have regarding the course.

Textbook
The textbook used in this course is Kumar V, et al (eds): Robbins Basic Pathology, 10th ed., Philadelphia, WB Saunders. It’s totally optional; so you should use it however it benefits you. You might find it useful to reinforce the content you receive in lectures. Then again, you might just have enough to read, in which case, you can focus on the lectures (and the lecture ppts), and you’ll be fine.

Lectures
Our lecture schedule is on the lectures page.

Assessments
There are three quizzes spaced fairly evenly throughout the course (dates and times are on our lectures page). We’ll use Zoom for these sessions, and we’ll do the quizzes using Kahoot – that way I can see how you guys are doing, and address any issues right then and there. There’s just one exam at the end of the course.

Grading

Quizzes 1 – 3 are worth 15 points each, and the exam is worth 50 points, for a total of 95 course points. Your quiz and exam scores will be added together (no weighting or anything, just a straightforward point total). Your point total will be compared to the total course points, and grades will be determined as follows:

  • A = 90 – 100% (85 – 95 points)
  • B = 80 – 89% (76 – 84 points)
  • C = 70 – 79% (66 – 75 points)

Grades will be posted on Canvas.

Oral & Maxillofacial Pathology Biopsy Service

We Diagnose. We Treat. We Teach.
We are the University of Michigan Oral & Maxillofacial Pathology!

ABOUT

For over 60 years, the University of Michigan School of Dentistry has been home to the Oral and Maxillofacial Pathology Biopsy Service composed of board-certified faculty members with extensive training in the clinical, radiographic, and histologic interpretation of lesions occurring in the head and neck area including the oral cavity and the jaw bones. Because of our educational focus, our pathologists are able to apply relevant clinicopathologic correlations to help ensure accurate diagnoses and recommendations for disease management based on contemporary standards of care. As members of an academic medical center, we provide you and your patients an oral diagnostic service based on latest research and innovation in health care.

Pathological diagnoses are faxed or mailed within 24 hours of soft tissue specimen receipt, with exceptions for hard tissue, special stains, direct immunofluorescence studies and cases sent on consult. We accept most medical insurance carriers and bill the patients directly. We serve the needs of clinicians throughout the United States.

SERVICES

Our histopathology laboratory offers a wide range of diagnostic services that address the needs of dentists, oral and maxillofacial surgeons and other dental specialists. These services include:

Standard tissue processing

Immunofluorescence testing

We perform direct immunofluorescence studies on specimens where additional testing is needed for a definitive diagnosis of a mucocutaneous disorder such as mucous membrane pemphigoid, erosive lichen planus, or pemphigus vulgaris. Please note that immunofluorescence testing requires the submission of specimens in formalin as well as Michel’s or Zeus solution which is available free of charge, by contacting our service.

We are available to discuss patient biopsy results and “next steps” after diagnosis including expedited referral to University of Michigan Oral and Maxillofacial Surgery.

For direct patient evaluation and management as well as CBCT interpretation please contact the Dental Faculty Associates.

TEAM

Our five pathologists are Diplomates of the American Board of Oral and Maxillofacial Pathology and provide diagnoses for common and complex oral diseases, including periodontal inflammation, odontogenic lesions, benign and malignant tumors of the oral and maxillofacial region, salivary gland tumors, autoimmune conditions involving the oral cavity, and complex oral manifestation of systemic diseases.

  1. Collection and Handling: Specimens should be procured using accepted surgical techniques. Because of the small size of most oral specimens it is especially important to avoid inducing crushing artifact through the injudicious use of clamps or forceps. Placement of a suture in the specimen prior to removal will allow for handling without damage. Use of electrosurgical instruments for the removal of small, delicate specimens should be avoided because of the possibility of heat damage and distortion. In some cases, physical damage to a critical area of a specimen may render it inadequate for diagnosis and a comment to that affect will be made in the pathology report.
  2. Labeling: Specimen containers and lab requisitions must be labeled with the full name of the patient and the submitting doctor and date the specimen was collected. If an improperly labeled specimen is received by the laboratory, a reasonable attempt will be made to confirm its identification. To expedite service, all pertinent areas of the lab requisition should be completed. If some information is not available, please state this on the requisition. Inadequately identified specimens will not be accepted for processing.
  3. Fixation: Specimens should be fixed in the buffered formalin solution supplied free of charge, by our laboratory. Specimen volume should not exceed 10% of the fixative volume. Larger specimens should be divided and submitted in multiple containers. Over time the fixative may evaporate from stored specimen containers. These should be discarded or returned to this laboratory for refilling, because the fixative cannot be reconstituted. Biopsy kits, which include UPS prepaid shipping labels, lab packs, specimen bottles with fixative, and lab requisition forms are available free of charge.
  4. Transportation: Transportation of your specimen using your UPS prepaid mailing label and lab packs is the preferred way to send your specimens. You can call UPS to arrange pickup of your specimen or place them it a UPS drop box. Specimens may also be sent to us using US mail but this can delay the delivery of your package and the possibility of it being lost in the mail without any tracking capability. Specimens can also be hand-carried to the laboratory. Please call 1-800-358-1011 to coordinate hand delivery if you or your patient would like drop off a specimen.
  5. Specimens Submitted in Zeus/Michel’s Solution for direct immunofluorescence (DIF) studies:
    1. Tissue must be placed in Zeus/Michel's solution
      • Keep solution refrigerated until needed
      • Do not freeze tissue or solution
    2. Tissue must reach our laboratory within 72 hours of the biopsy
      • Please use our 2 day UPS label & lab pack for sending your specimen to us
    3. In addition, please submit a separate tissue specimen in formalin for conventional H&E histology

    Please use our 2-day UPS label & lab pack for sending your specimen to us.

Submission during the winter months

Specimens sent during the winter months (December through March): The following procedure should be used in order to avoid freeze damage to specimens in transit to the laboratory.

  1. Fix specimen in formalin solution for 24 hours.
  2. Decant formalin and replace with 70% alcohol prior to mailing. Ethyl alcohol is preferred but methyl alcohol or isopropyl alcohol is acceptable following formalin fixation. Please note, formalin is a hazardous waste and must be handled as such.

Adherence to the above procedures will insure expeditious handling and optimum quality of biopsy specimens. We look forward to serving you and your patients.
