Abstract In some cases, keratoacanthomas can be indistinguishable from squamous cell carcinoma, making the gold standard treatment surgical excision with histopathological evaluation. The surgical defects created on the back of the hand can be challenging to repair. We describe the use of bilateral rotation flap as an option in this area, and discuss the indications and contraindications of some of the possible surgical techniques for reconstruction of the dorsum of the hand.

We describe the use of modified Tripier flap for reconstruction of a surgical defect in the lower eyelid region, after excision of nodular basal cell carcinoma.

Knowledge of the inverted "T" incision - used in plastic, oncologic and orthopedic surgery - has allowed its adaptation for the diagnostic assessment and therapeutical approach of acral, nodular lesions. The authors describe the use of this technique for the surgical approach of a patient with a plantar nodular lesion, further diagnosed as a calcified angioleiomyoma.

We report the case of an 11-year-old male patient with a histopathological and immunohistochemical diagnosis of dermatofibroma with an atypical clinical presentation on the right forearm. Although dermatofibroma is considered a benign skin tumor, some of its differential diagnoses, such as dermatofibrosarcoma protuberans and malignant fibrous histiocytoma, are truly aggressive. Lesions with atypical clinical aspects and topology associated with specific histopathological variants are some of the criteria for complete tumor excision.

Relatamos o caso de um paciente adulto, imunocompetente, com eumicetoma por Madurella mycetomatis, localizado nos glúteos e coxas, diagnosticado após 30 anos de evolução clínica. Tratado no decorrer de quatro anos com fluconazol e itraconazol, associado a cinco tempos cirúrgicos de exérese dos nódulos subcutâneos. No oitavo ano de follow-up ocorreu recidiva de apenas um nódulo na região infraglútea, o qual foi excisado cirurgicamente, mantendo-se assintomático desde então.

We report a case of eumycetoma by Madurella mycetomatis on the buttocks and thighs in an adult immunocompetent patient, diagnosed after 30 years of clinical development. He was treated over four years with fluconazol and itraconazol associated with five times surgical excisions of subcutaneous nodules. At the eighth year of follow-up, one nodule recurred on the right infragluteal region, which was excised surgically and has remained asymptomatic ever since.

A reconstrução de defeitos cirúrgicos na região pubiana é um desafio para qualquer cirurgião. Objetivamos demonstrar a aplicação do retalho bilobado na reconstrução da região pubiana, após excisão de HPV recidivante aos tratamentos convencionais. Apesar da utilização clássica deste retalho ser na região nasal, aplicações em áreas distintas também se mostraram com excelentes resultados funcionais e estéticos.

Reconstruction of surgical defects in the pubic region is a challenge to any surgeon. Our goal was to demonstrate the use of the bilobed flap to reconstruct the pubic region skin after the excision of a recurrent HPV lesion, resistant to conventional treatments. In spite of its classical use in nasal reconstructions, the bilobed flap has applications in extranasal defects, with excellent functional and aesthetic results.

Paciente do sexo masculino, 28 anos, com surgimento de pápula eritemato-amarelada na coxa direita, assintomática. Foi realizado biópsia excisional da lesão para exame histopatológico, tendo sido observado células gigantes multinucleares do tipo Touton e imunohistoquimica com CD1a e S100 negativos e CD4 e CD68 positivos. Pelos achados clinicohistopatológicos associados a imunohistoquimica concluímos ser um caso de xantogranuloma do tipo adulto. Por ter sido uma lesão solitária sem outros sinais e sintomas clínicos, a conduta adotada foi orientação quanto a doença.

Male patient, 28 years old, presented with an asymptomatic yellowish erythematous papule on his right thigh. Excisional biopsy was performed for histopathological examination of the lesion. Multinucleated cells (Touton giant cells) were observed. S100 immunohistochemistry was negative for CD1a and positive for CD4 and CD68. Based on clinical and histopathological findings associated with immunohistochemistry, we concluded that it was a case of adult-type xanthogranuloma. Because it was a solitary lesion without other clinical signs and symptoms, the medical conduct adopted was patient orientation.
