Article Synopsis
  • - Verrucous carcinoma is a rare, low-grade type of squamous cell carcinoma that generally does not spread (metastasize) to other parts of the body but can grow aggressively in the local area.
  • - The study analyzed 38 cases of verrucous carcinoma treated with Mohs micrographic surgery, showing a local recurrence rate of 16%, with only a small percentage having lymph node metastasis (3%).
  • - Due to the high rates of local recurrence associated with traditional wide local excision, Mohs surgery is recommended as the preferred treatment, but more research is needed to compare the effectiveness of Mohs and wide local excision.

Sialadenoma papilliferum with potentially malignant features.

J Clin Pathol

April 2010

Division of Pathology, Department of Diagnostic and Therapeutic Sciences, Meikai University School of Dentistry, Saitama 350-0283, Japan.

Article Synopsis
  • - Sialadenoma papilliferum (SP) is generally a benign lesion that grows slowly, but in this report, an unusual case showed rapid enlargement and features that made it resemble a verrucous carcinoma.
  • - Radiographic assessments revealed bone resorption in the mandible, indicating a more aggressive behavior than typical SP cases, which raises questions about its classification.
  • - The study highlights atypical histological characteristics, suggesting that SP may have malignant potential and complicates the understanding of SP by referencing four other cases where malignancy was associated with it in different contexts.

Animal models of papillomavirus pathogenesis.

Virus Res

November 2002

Department of Veterinary Pathology, Institute of Comparative Medicine, Glasgow University, UK.

Article Synopsis
  • Tumorigenesis caused by papillomavirus (PV) was first shown in rabbits and cattle, but the idea that viruses could cause cancer in humans was largely ignored until the late 1970s when some viruses were finally recognized as 'tumour viruses.'
  • In 1995, the WHO officially acknowledged that HPV types 16 and 18 are carcinogenic to humans, thanks to studies of animal PVs that served both as disease agents and models for human infection.
  • Animal PVs can lead to severe diseases in livestock and pets, such as teat papillomatosis in cattle and equine sarcoids, highlighting the importance of ongoing research to understand these infections and their impacts on animal health.
