Penectomy grossing deals with the cut-up of penile surgical specimens. It includes both total and partial penectomies.
Introduction
It is done for penile cancer.
Orientation/anatomy note
- Dorsal aspect of penis = where the corpora cavernosa are; "anterior" when the penis is limp and hanging downward.
- Ventral aspect of penis = where the urethra/frenulum are; "posterior" when the penis is limp and hanging downward.
Penis anatomy. (WC/Gray's Anatomy)
Penis anatomy - cross section. (WC/Gray's Anatomy)
Opening
- +/-Insert probe into urethra from the proximal aspect (surgical margin).
- No cutting necessary. ‡
- Place in formalin.
Notes:
Protocol
Dimensions, weight and inking:
- Type: [partial penectomy / penectomy].
- Size of specimen (length, left-right, dorsal-ventral): ___ x ___ x ___ cm.
- Foreskin size (length, thickness): ___ x ___ cm.
- Inking of margin: [colour].
Tumour:
- Dimensions (length, left-right, dorsal-ventral): ___ x ___ x ___ cm.
- Location: [glans / coronal sulcus].
- Colour: [tan / white].
- Growth pattern: [friable / fungating / papillary / verrucous / ulcerated].
- Consistency: [friable / soft / rubbery / hard ].
- Circumscription: [well demarcated / pushing border / infiltrative border].
- Hemorrhage: [present / absent].
- Necrosis: [present / absent].
- Margin: [nearest margin ___, distance ___ cm / positive margin, location ___].
- Extension into:
- Frenulum: [absent / suspicious / present].
- Glans penis: [absent / suspicious / present].
- Corpora cavernosa: [absent / suspicious / present].
- Corpora spongiosum: [absent / suspicious / present].
- Urethra: [absent / suspicious / present].
Representative sections:
- Resection margin on edge serially sectioned.
- Sagittal section of glans penis.
- Parasagittal sections of glans penis (left, right).
- Tumour - 1 section/cm.
Protocol notes
- Margin inked.
- A slice is cut-off the penis at the site of the resection margin. This slice is then divided into left and right with a sagittal cut. Each portion (left and right) is sectioned with parasagittal cuts such that it is submitted as an on edge margin. ‡
- The glans penis should be cut in the midline in the sagittal plane, and parasagittally.[2]
Alternate approaches
- ‡ The CAP protocol for Penis (Version 3.2.0.0) suggests taking the margin en face.[3]
