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.

A rare malignancy: A case report of early progression of anal Buschke-Löwenstein tumor into squamous cell carcinoma in an immunocompetent patient.

Introduction And Importance: Buschke-Löwenstein tumor (BLT) is a rare perianal lesion caused by low-risk mucosal HPV 6 or 11 but less frequently associated with high-risk HPV types. It is a large, exophytic, verrucous lesion of the anogenital region. BLT presents as a benign tumor but exhibits malignant clinical behavior and has a high rate of local recurrence and malignant transformation.

Classificatory updates in verrucous and cuniculatum carcinomas: Insights from the 5 edition of WHO-IARC head and neck tumor classification.

The International Agency for Research on Cancer (IARC) and World Health Organization (WHO) collaboratively produce the 'WHO Blue Books' essential tools standardizing the diagnostic process for human cancers. Regular updates in this classification accommodate emerging molecular discoveries, advances in immunohistochemical techniques, and evolving clinical insights. The 5 edition of the WHO/IARC classification of head and neck tumors refines the 'Oral Cavity and Mobile Tongue' chapter, including sections for non-neoplastic lesions, epithelial tumors, and tumors of uncertain histogenesis.

Proliferative Verrucous Leukoplakia Presenting as a Ring Around the Collar and Cancer: A Case Report.

Proliferative verrucous leukoplakia (PVL) is an oral mucosa lesion with a high rate of malignant transformation. The diagnosis is often difficult, especially when the initial lesion is a simple homogeneous white leukoplakia, and when located only on the gingiva or palate. Moreover, the anatomopathological analysis is non-specific in the initial stages.

Fine scalpel surgery: preserving the dartos muscle in a patient with scrotal and perigenital giant Buschke-Löwenstein tumors.

Giant condyloma acuminatum (GCA), alternatively referred to as a Buschke-Löwenstein tumor (BLT), is an uncommon, benign, but locally aggressive form of verrucous carcinoma. The condition usually affects the male population under the age of 50 years; however, there have been rare reports of pediatric cases. Various risk factors such as smoking, diabetes, promiscuous behavior, poor hygiene, immunosuppression, and others are linked to the development of this condition.

Severe Maxillectomy Defect Rehabilitation with an Implant-Retained Obturator Prosthesis: A Case Report.

Conventional obturator prostheses might cause dissatisfaction in patients with hard or soft palate defects due to inadequate retention and function during speech, mastication, and swallowing. Thus, surgical reconstruction and implant-supported obturators are considered as alternative treatments for these patients. This case-report study describes the prosthetic reconstruction of an 88-year-old patient suffering from a hard palate defect after surgical resection of verrucous carcinoma in the left side of the hard palate.

Maxillary interim obturator prosthesis fabrication for a patient with limited mouth opening with a digital approach: A clinical report.

Squamous cell carcinoma is a common malignant condition affecting the oral cavity and may involve the surrounding maxillofacial regions. Treatment commonly involves resection of the tumor, followed by prosthetic rehabilitation of the resection defect. This clinical report presents a 62-year-old Asian male patient who had previously undergone surgical resection, resulting in a post-surgical Aramany Class II maxillary defect.
