Head and Neck Pathology Grossing GuidelinesDo not cut any HN specimens unless you are fully oriented anatomically

Orient by anatomic structures (oral tongue, junction of buccal/gingival mucosa, alveolar ridge, angle of jaw, hard palate, etc)

For mandibulectomies/maxillectomies, please ask for help if unsure Ink resection margins Describe all abnormalities: size (staging cutoffs: 2 cm, 4 cm), location, extent,

depth (staging cutoffs: 0.5 cm, 1 cm), distance to margins Sample all margins (if grossly close, e.g. 1 cm, submit perpendicular section;

otherwise submit a shave of the margin closest to tumor) Sample tumor:

o Show relationship to peripheral/deep marginso Show maximum depth of invasion

Specimens containing mandible or maxilla:o Bone marginso Sections of bone adjacent to tumor or gross involvement of bone

Diagrams and gross photos are appreciated

[Describe orientation provided]. The mucosa is remarkable for [describe lesion – location, size, distance from margins]. Sectioning reveals the lesion has a [describe cut surface of lesion] and *** cm maximum thickness. The lesion measures *** cm from the deep resection margin [indicate extent of lesion].

The remaining mucosal surface is [smooth, pink, glistening, unremarkable]. Representative sections are submitted [describe cassette submission].

Cassette Submission: 8-10 cassettes

Cassette Submission: All tissue submitted

- Proper embedding for vertical sectioning through the mucosal surface is critical for the determination of early stromal invasion. To achieve this, instruction should be given to the histotechnologist for proper embedding. If the mucosal surface can be identified, instruct the histotechnologist to cut on edge. If the specimen is greater than 4 mm, bisect the specimen perpendicular to mucosal surface.

- Any head and neck biopsy smaller than 4 mm, request three separate slides with serial cuts up front. Subsequent recuts may lose diagnostic tissue.

Specimen Type: TOTAL LARYNGECTOMYProcedure:

1. Orient specimen and determine structures present If radical neck dissection present, remove from larynx and process as

described in the manual Note presence or absence of thyroid and hyoid bone Identify tracheostomy site if present

2. Ink entire soft tissue margin Black- right and Blue- left

3. Remove inferior tracheal ring, unless lesion is close and a perpendicular section would be more appropriate

4. Open along the posterior midline (splitting cricoid cartilage) and prop open and pin on corkboard to fix overnight

5. Take gross photographs and draw diagrams6. Describe size/presences of lesion/ulcerations and structures they involve:

a. Indicate location of lesion-supraglottic: (extends from the tip of epiglottis to the apex of ventricle and includes the epiglottis, aryepiglottic folds, arytenoids, false vocal cords, and the ventricle)-gl ottic : (extends from the ventricle to 0.5-1.0 cm below the true vocal cord and includes the anterior and posterior commissures)-subglottic: (extends from 1.0 cm below the true vocal cord to inferior rim of the cricoid cartilage)-transglottic

* note if lesion crosses the midlineb. Indicate extent of lesion: document if lesion involves base of tongue, epiglottis, piriform sinus, aryepiglottic folds, arytenoid mucosa, anterior and posterior midlines, hydoid bone, thyroid, cartilage (thyroid and/or cricoid), strap muscles, and involvement of any additional tissue/organs present

7. Describe remainder of specimen and additional structures

Page 8: pathology.ucla.edupathology.ucla.edu/workfiles/Education/Head_Neck_2018v3.docx · Web viewHead and Neck Pathology Grossing Guidelines Do not cut any HN specimens unless y ou are fully

8. Section along anterior midline and photograph cut surface9. Describe maximum thickness and distance to all margins

Gross Template: Labeled with the patient’s name (last name, first name), medical record number (#), designated “***”, and received [fresh/in formalin] is a total laryngectomy measuring *** cm (superior-inferior) x *** cm (right-left) x *** cm (anterior-posterior). The hyoid bone measures *** x *** x *** cm.The thyroid is *** x *** x *** cm. [Describe skin on anterior surface and presence of tracheostomy site].

The specimen is opened along the posterior midline to reveal a [supra-, sub-, trans- glottic] lesion [describe nature of lesion-exophytic, ulcerated, etc] located on the [indicate laterality-right, left, both, midline] measuring *** x *** cm. The lesion [crosses/does not cross] the midline. The lesion involves/does not involve the vocal cords. The lesion involves [describe extent-piriform sinus, aryepiglottic folds, cartilage, bone, thyroid, strap muscles, anterior and posterior commissure, tracheal rings, etc.]. The lesion involves/does not involve the outer cortex thyroid cartilage or tissue beyond larynx.

The remaining mucosa is [tan, smooth, unremarkable]. [Describe number/size of lymph nodes identified]. Representative sections are submitted [describe cassette submission].

Specimen Type: HEMILARYNGECTOMYProcedure:

1. Fix the specimen for at least 2-4 hoursa. Specimen will consist of true and false cord and underlying cartilage

2. Separate the soft tissue of the entire vocal cord from the underlying cartilage3. Section vertically at 2-3 mm internal to include true and false cord4. Submit each level in separate cassettes, entirely and sequentially

The laryngeal mucosa is remarkable for [describe any lesions including color, size, location, and extent of anatomical landmarks]. The remaining mucosa is [tan, smooth, unremarkable]. Representative sections are submitted [describe cassette submission].

Cassette Submission: 10-15 cassettes- Submit each slice in separate cassette sequentially, to allow for proper

localization of the tumor
