This transcript provides a detailed gross description of a surgically excised tissue specimen, likely a skin and soft tissue excision for a tumor or lesion. The specimen measures 7.8 x 3.9 cm and contains a 6.3 x 2.5 cm ulcerative, tan-pink to red, poorly demarcated lesion. The orientation is established using short (12:00 superior) and long (9:00 medial) stitches. Specific resection margin distances are recorded, ranging from 0.5 cm to 0.8 cm. The deep aspect features moderate amounts of attached muscle and fascia. The specimen has been sequentially inked for margin identification, and subsequent sectioning revealed a tan-yellow, granular cut surface that extends into the underlying muscle and subcutaneous fat, positioned 0.6 cm from the closest deep resection margin. Representative sections, including the entire radial margin and areas showing the granular cut surface, are submitted for microscopic evaluation.
Pathology Gross Description of Excision Specimen
0:00:15 Specimen Dimensions and Gross Features: The specimen is an elliptic skin excision measuring 7.8 x 3.9 cm, with a depth of 2.6 cm.
0:00:46 Lesion Description: It displays a 6.3 x 2.5 cm tan-pink to red lesion that is ulcerative and poorly demarcated.
0:01:15 Resection Margin Distances: The closest tumor-to-margin distances are meticulously recorded:
0:01:48 Specimen Orientation: Orientation is established using a short stitch at 12:00 (superior) and a long stitch at 9:00 (medial).
0:01:57 Deep Aspect: The deep surface is described as tan-brown to yellow and scabrous, with moderate amounts of attached muscle and fascia.
0:02:08 Inking Scheme: The specimen is inked blue along the 12:00 aspect, black along the 6:00 aspect, and orange along the deep aspect.
0:02:49 Radial Margin Processing: The radial resection margin is removed en foss sequentially in a clockwise fashion, beginning from 12:00 superior to 11:00 superior.
0:03:27 Cut Surface Findings: Serial sectioning reveals a tan-yellow, granular cut surface that extends into the underlying muscle layer and subcutaneous fat.
0:04:06 Deep Margin Measurement: The granular cut surface is 0.6 cm from the closest deep resection margin.
0:04:15 Section Submission: Representative sections are submitted, including the entire radial skin and soft tissue margin (B1-B9) and representative sections of the granular cut surface, including the deep resection margin (B10-B16).
