ABSTRACT
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.

O eritema pigmentar fixo geralmente representa uma reação cutânea adversa a medicamentos caracterizada pelo surgimento de lesões eritematosas arredondadas ou ovais que recorrem no mesmo sítio em minutos a horas após uma nova exposição ao medicamento previamente utilizado. As lesões podem ser únicas ou múltiplas e esmaecem em poucos dias deixando pigmentação hipercrômica residual, sendo os anti-inflamatórios e antibióticos, frequentes causadores. Já o herpes labial é causado principalmente pelo HSV1 e se manifesta com vesículas agrupadas sobre base eritematosa com posterior evolução para crostas e pode ser desencadeado por estresse, trauma etc. O objetivo do presente trabalho é demonstrar um caso de eritema pigmentar fixo simulando herpes labial, relacionado ao uso de fluconazol, visto que existem relativamente poucos relatos desta associação na literatura médica...
