Contoured technique for lentigo maligna

The surgical approach to lentigo maligna is a challenge to dermatologists, given the difficulty of clinical delimitation of borders. We report here a case of a 69-year-old female patient presenting with brownish macules on her face, since 10 years ago, with histopathological diagnosis of lentigo maligna. The surgical management employed was excision of visible borders with the contoured technique and immediate submission of these borders for histopathological analysis before complete excision of the tumor. This technique is a variant of staged excision, with lower rates of recurrence and acceptable aesthetic results.

Introduction: Infantile hepatic hemangioendothelioma (HHI) is the primary liver tumor more commonin childhood. Usually occurs before the 6 months of age. These tumors can be diagnosed in utero,where the large arteriovenous shunting cause non-inmune hydrops fetalis. Objetive: Describe a case ofa dead fetus with a hepatic hemangioendothelioma and a discussion on this topic is done. Clinical case:Product of pregnancy of 33 weeks of gestation in a 23 years old woman, obstetrical ultrasound evidencedfetal hydrops secondary to the presence of liver tumor, the patient died minutes after birth. The necropsyshowed a male fetus of 3250gr in weight, with a liver tumor with solid features, which histopathologicalexamination corresponds to a HHI. Conclusions: We report the pathological study of a perinatal autopsydone to a fetus with a congenital tumor, an HHI that cause non-inmune hydrops fetalis.
