Introduction:
Pseudoepitheliomatous keratotic and micaceous balanitis (PKMB) is an extremely rare disease. Herein, we report a case of PKMB in a patient who underwent two surgical procedures, since the 5-FU cream was not available.
Presentation of case:
A 50 year-old Korean man undergoing circumcision in a local clinic presented with a tumor-like lesion on the glans penis. Peeling the mass was performed to remove the entire mass after an excisional biopsy. A pathologic finding of mass showed hyperkeratotic and papillomatous squamous epithelium without obvious cytologic atypia. Considering that the lesion recurred after 4 weeks, the patient underwent glansectomy with split-thickness skin graft (STSG). There had been no evidence of recurrence at the surgical site during the follow-up at 6 years postoperatively.
Discussion:
If the 5-FU cream is not available, two surgical procedures can be performed for treatment and biopsy. Peeling the mass has the advantage of confirming the characteristics of the whole lesion, but it cannot confirm tumor invasion because it is unable to obtain the subepithelial layer. Glansectomy is able to accurately identify the tumor stage because it removes the tumor and total glans penis and has excellent outcome.
Conclusion:
PKMB is very rare and has a characteristic appearance, which is mica-like crusts and keratotic horny mass on the glans penis. Glansectomy with STSG is a good procedure when the 5-FU cream was not available.
