Primary malignant urethral melanoma resembling a urethral
caruncle. Urol Case Rep 2017; 15: 28-9.
Melanomas may be confused with urethral polyps, mucosal prolapse or
caruncles [14].
The biopsy histology confirmed the diagnosis of urethral
caruncle (Figures 1 and 2).
The seeds are 4-5 mm in diameter, dark green to grey-black, rounded with conspicuous
caruncle (Irvine, 1969).
The examination demonstrated normal external genitalia, normal urethra without
caruncle, vagina mucosa with mild post-menopausal atrophic changes, grade one cystocele with midline urethral alignment, absence of rectocele, and no stress incontinence with valsalva.
Other differential diagnoses include urethral
caruncle, urethral diverticulum [45, 46], malignant lymphoma, sarcoma, extravesical leiomyoma of the bladder, Gartner's duct cyst, and ectopic urethral orifice [35].
Primary malignant melanoma mimicking urethral
caruncle. Case report.
The
caruncle on the nasal canthus contains both conjunctival and cutaneous structures and tumours can be of skin or mucosal origin.
Sebaceous carcinoma of the eyelid, eyebrow,
caruncle, and orbit.
The mandibular gland shows a rounded contour and its duct crosses along the occiptomandibular face of the digastric muscle and styloglossus muscle and opens in the mouth on the sublingual
caruncle near the frenulum (Figure 1 and 2).
In this region there is a reddish elevation in the lacrimal
caruncle. The next most acute apex is directed superiorly.
