Lip verrucous carcinoma in a pregnant woman successfully treated with carbon dioxide laser surgery

Oral verrucous carcinoma: a diagnostic and therapeutic challenge

BACKGROUND

Verrucous carcinoma is a low-grade variant of squamous cell carcinoma with specific morphologic, cytokinetic and clinical features. Despite low mitotic activity and slow growth, it can infiltrate adjacent tissues in advanced stages but does not metastasize. The most frequently affected site is the oral cavity. The following article provides latest updates in the etiology, clinical presentation, diagnostics and treatment options in oral verrucous carcinoma and discusses the existing dilemmas linked to this unique malignancy.

CONCLUSIONS

Oral verrucous carcinoma must be differentiated from conventional squamous cell carcinoma due to its less aggressive behaviour with a more favourable prognosis. Close communication between clinician and pathologist is mandatory for making a correct diagnosis. Primary surgery with negative surgical margins seems to be the most successful treatment. However, management recommendations are not uniform since they are mostly based on case reports and small retrospective case series. Prospective and pooled multi-institutional studies are therefore needed.

A huge verrucous carcinoma of the lower lip reconstructed by double Abbe flap: A case report and literature review

Lip verrucous carcinoma is a rare low-grade neoplasm, with an unsightly appearance and locally aggressive nature. Treatment of verrucous carcinoma is as yet challenging, no well-defined guidelines for effective and safe management of this disease are available. A case of a patient with a huge verrucous carcinoma of the lower lip successfully treated by surgical excision and double Abbe flap reconstruction technique is presented, and striking features of lip locations of this tumor as well as their management are discussed.

Verrucous hyperplasia and verrucous carcinoma in head and neck: use and benefit of methotrexate

Background and aim: Verrucous hyperplasia (VH) and verrucous carcinoma (VC) of the head and neck are two (pre)malignant entities that are slowly progressive with low tendency to metastasize. However, they can reduce the patient's Quality of Life (QoL) and may even transform into squamous cell carcinoma (SCC). As they are typically approached by surgical resection, some patients do not qualify for surgery. Methotrexate may be a systemic alternative but the response is mostly not durable. This case report tries to illustrate the potential role of methotrexate in VH/VC of the head and neck.Method: We describe four cases of patients with VH or VC of the head and neck who received methotrexate (40-60 mg/m²) in a weekly or two-weekly interval.Results: Two patients received methotrexate in a neoadjuvant setting. The first patient achieved a macroscopical complete response after 16 cycles and remained in remission after surgery. The second patient suffered from residual disease after 26 cycles and refused radical surgery.Two other patients refused surgery at the time of diagnosis and were proposed methotrexate as a salvage treatment. The first patient had an ongoing response on methotrexate after >60 cycles. The second patient achieved macroscopical complete remission after 28 cycles of methotrexate but suffered relapse by developing an oropharyngeal SCC in the same region.Conclusion: When surgery is not desirable in VH and/or VC, patients can be treated with methotrexate which has a reasonable effect and seems to be well tolerated. Nevertheless, surgery should be the preferred strategy to achieve complete remission.

Utilization of Laser Therapy During Pregnancy: A Systematic Review of the Maternal and Fetal Effects Reported From 1960 to 2017

BACKGROUND

Due to concerns regarding maternal and fetal safety and the absence of evidence to the contrary, laser treatment during pregnancy has traditionally been limited to situations of absolute necessity.

OBJECTIVE

This review seeks to examine the available evidence to determine the safety of laser therapy during pregnancy.

METHODS

Medical databases were searched for relevant reports from all specialties regarding the use of lasers during pregnancy from 1960 to 2017. A legal case review was also performed.

RESULTS

Twenty-two publications in the literature reported the use of various laser wavelengths in 380 pregnant women during all trimesters. Other than 1 case of premature rupture of membranes questionably related to the laser treatment, there were no cases of maternal or fetal morbidity or mortality, premature labor, or identifiable fetal stress.

CONCLUSION

The available evidence, limited to low evidence level case reports and series, indicates cutaneous laser treatment during pregnancy is safe for both mother and fetus. Furthermore, laser physics and optics dictate there should theoretically be no risk of fetal laser exposure from commonly used cutaneous lasers.
