Oral phaeohyphomycosis in a patient with squamocellular carcinoma of the lip: second case report

Abstract This communication reports the second known case of oral phaeohyphomycosis in a patient with squamocellular carcinoma of the lip. The patient, an 82-year-old black woman, a former smoker (for more than 30 years), suffering from an ulcerous vegetative lesion in the middle third of the lower lip for approximately 12 months. The result of the histopathological analysis indicated carcinoma, with well-differentiated keratinized squamous cells and the presence of septate mycelial filaments. In the direct mycological examination, thick and dematiaceous septate mycelial filaments were observed. After the resection surgery, the patient did not need to use an antifungal drug to treat the phaeohyphomycosis, and no follow-up radiotherapy was needed to treat the squamocellular carcinoma. We stress that the presence of the squamocellular lesion of the lip was a possible contributing factor to the infection.

Lower lip reconstruction with nasolabial flap - going back to basics

Squamous cell carcinoma of the lower lip is frequent, and radical excision sometimes leads to complex defects. Many lip repair techniques are aggressive requiring general anesthesia and a prolonged post-operative period. The nasolabial flap, while a common flap for the repair of other facial defects, is an under-recognized option for the reconstruction of the lower lip. We describe the use of nasolabial flap for the repair of a large defect of the lower lip in a ninety year-old male, with good functional results and acceptable cosmetic outcome. We believe the nasolabial flap is a good alternative for intermediate-to-large lower lip defects in patients with impaired general condition.

Queilite actínica: avaliação comparativa estética e funcional entre as vermelhectomias clássica e em W-plastia / Actinic cheilitis: aesthetic and functional comparative evaluation of vermilionectomy using the classic and W-plasty techniques

FUNDAMENTO: A queilite actínica crônica é a ceratose actínica localizada no vermelhão labial. O tratamento é de crucial importância, devido ao potencial de transformação maligna. OBJETIVO: Avaliar os resultados estéticos e funcionais das vermelhectomias clássica e em W-plastia na queilite actínica. Na técnica clássica, a cicatriz é linear; na W-plastia, em linha quebrada. MÉTODOS: Foram tratados 32 pacientes com diagnóstico clínico e histopatológico de queilite actínica. Quinze deles foram submetidos à técnica em W-plastia e 17, à técnica clássica. Avaliaram-se parâmetros como retração cicatricial e alterações funcionais. RESULTADOS: Houve associação estatisticamente significativa entre a técnica utilizada e a presença de retração cicatricial, sendo a associação positiva com a clássica (p=0,01 com correção de Yates). O risco relativo (odds ratio - OR) calculado foi de 11,25, ou seja, houve maior chance de retração nos pacientes submetidos à técnica clássica. Nenhuma das técnicas apresentou alterações funcionais. Avaliaram-se complicações pós-operatórias como presença de crostas, lábios secos, parestesia e deiscência de sutura. Não houve associação estatisticamente significante entre as complicações e a técnica utilizada (p=0,69). CONCLUSÃO: Concluiu-se que a vermelhectomia em W-plastia oferece melhores resultados estéticos e índices de complicações semelhantes.

BACKGROUND: Chronic actinic cheilitis is actinic keratosis located on the vermilion border. Treatment is essential because of the potential for malignant transformation. OBJECTIVE: To evaluate the aesthetic and functional results of vermilionectomy using the classic and Wplasty techniques in actinic cheilitis. In the classic technique, the scar is linear and in the W-plasty one, it is a broken line. METHODS: 32 patients with clinical and histopathological diagnosis of actinic cheilitis were treated. Out of the 32 patients, 15 underwent the W-plasty technique and 17 underwent the classic one. We evaluated parameters such as scar retraction and functional changes. RESULTS: A statistically significant association between the technique used and scar retraction was found, which was positive when using the classic technique (p = 0.01 with Yates' correction). The odds ratio was calculated at 11.25, i.e., there was a greater chance of retraction in patients undergoing the classic technique. Both techniques revealed no functional changes. We evaluated postoperative complications such as the presence of crusts, dry lips, paresthesia, and suture dehiscence. There was no statistically significant association between complications and the technique used (p = 0.69). CONCLUSION: We concluded that vermilionectomy using the W-plasty technique shows better cosmetic results and similar complication rates.
