Malignant Transformation of Long-Standing Pseudoepitheliomatous Keratotic and Micaceous Balanitis (PKMB) Presenting as Urethral Obstruction.

Hereby, we present a rare case of malignant transformation in a long-standing case of pseudoepitheliomatous keratotic and micaceous balanitis (PKMB), which typically affects older men. PKMB presents as whitish or silvery keratotic plaques on the glans and can remain stable for years, leading to potential confusion regarding its progression. The patient in this case experienced urinary obstruction due to tumorous ingrowth, prompting an investigation. Despite previous treatments, including fluorouracil (5-FU) and cryoablation, the lesion persisted, eventually growing in size and becoming malodorous. Initial biopsy showed PKMB without malignancy, but subsequent deeper biopsy revealed verrucous carcinoma. The patient underwent glansectomy and reconstruction with a full-thickness skin graft, achieving a disease-free state postoperatively. The paper underscores the importance of thorough investigation for malignancy in PKMB cases, the possibility of deeper malignancy missed by superficial biopsy, and the need for early diagnosis to enable organ-sparing treatments.

Post-COVID-19 Demyelinating Disease and Its Effect on the Lower Urinary Tract: A Rare Case of a 14-Year-Old Man.

The COVID-19 pandemic caused by severe acute respiratory coronavirus 2 (SARS-CoV-2) has led to a wide range of manifestations, including urological issues. Patients with COVID-19 frequently experience complications, such as acute kidney injury (AKI) and thromboembolism. Neurological problems, including demyelination in the central and peripheral nervous systems, have also been reported in COVID-19 cases. This neurological damage can be attributed to the virus's neurotropic and neuro-invasive properties. This case study presents a 14-year-old patient who developed severe lower urinary tract symptoms following a COVID-19 infection, leading to a demyelinating disease affecting the lower urinary tract. The patient was managed successfully with specialized neuro-urological care, highlighting the importance of multidisciplinary collaboration in managing post-COVID-19 complications. Clinicians need to be vigilant about potential neurological manifestations in COVID-19 patients, including those affecting the urinary system, and patients should seek specialized medical attention for persistent symptoms.
