RESUMO
Frontal fibrosing alopecia (FFA) and fibrosing alopecia in a pattern distribution (FAPD) as originally reported by Kossard in 1994 and by Zinkernagel and Trüeb in 2000, respectively, represent two distinct patterns of cicatricial pattern hair loss. Both share a patterned distribution and histological evidence of a lichenoid follicular inflammation with fibrosis. FFA is characterized by a marginal alopecia along the frontotemporal hairline, and FAPD by a progressive alopecia of the centroparietal scalp. Since the original reports, evidence has accumulated that there exists considerable clinical overlap among FFA, FAPD, and lichen planopilaris, with coexistence of features of the three conditions within the same individual. Moreover, familial cases of FFA have been reported, pointing to a possible genetic background to the condition. Our observation of familial occurrence of FFA and FAPD in daughter and mother, respectively, further underscore a nosologic relationship between the two conditions with respect to both an androgenetic background and the (lichenoid) inflammatory reaction pattern.
RESUMO
Introduction: Transmigration is pre-eruptive migration of tooth across the midline. The etiology of this rare anomaly is unknown. Transmigration is largely related to mandibular canines. Although maxillary canine transmigrations are found in the literature, they are still a rare entity. Objective: The aim of the present paper is to report two cases of unusual transmigrations of canines in two immediate members of a family and to report the first case of simultaneous transmigration of maxillary and mandibular canines in an Indian adolescent. Case report: A rare case of simultaneous transmigration of maxillary and mandibular canine in Indian adolescent along with bilateral transmigration of mandibular canines in her father is described here. Conclusion: Transmigration of canines in two immediate members of family needs to be further studied for familial occurrence of transmigration.
