ABSTRACT
O estudo da etiologia das formas congênitas ditas cicatriciais, que incluem bandas cicatriciais congênitas e formas cicatriciais das fissuras labiais, apresenta diversas teorias, que fundamentam seu aparecimento, porém não justificam todos os aspectos envolvidos nessas malformações. Neste artigo são apresentados 4 casos de pacientes portadores da forma cicatricial de Keith, submetidos à realização de queiloplastia pela técnica de Spina, comparados a 1 caso de paciente portador de cicatriz traumática. Todos os pacientes tiveram amostra de tecido enviada para estudo histopatológico, com coloração com hematoxilina-eosina. Os casos estudados apresentaram semelhanças entre a pele embrionária e a cicatriz comum.
Examinations of the etiology of congenital cicatricial presentations, which include congenital constriction bands and cicatricial presentations of cleft lip, have provided several theories that explain their development; however, they do not explain all the aspects involved in these malformations. In the present article, we present the cases of 4 patients with Keith's lip scar who underwent cheiloplasty using the spina technique. These cases were compared with 1 case of a patient with a traumatic scar. Tissue samples were obtained from all the patients for histopathological examination using hematoxylin-eosin staining. The cases under study exhibited similarities in embryonic skin and common scar tissue.

The fetal consequences of chickenpox complicating pregnancy depends on the period of gestation at which the infection is contracted. The extremely rare classical form of congenital varicella syndrome, resulting from maternal varicella infection in the first trimester of pregnancy, is being reported here. The unusual features in this baby are bilateral hypoplastic lower extremities, fracture of bones, a normal electroencephalogram and phantom hernias of the anterior abdominal wall.
