Abstract

The brown booby (Sula leucogaster) is a typically pantropical seabird with a distribution spanning much of the southern hemisphere. Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for vulnerable. Therefore, this case report aimed to report the case of a brown booby diagnosed with a benign intratubular seminoma. Upon necropsy examination, an increase in the left testicle volume was observed. The histopathological examination confirmed the diagnosis of benign seminoma. Seminomas are rare in birds, especially those exhibiting benign behavior. Microscopically, the testicle was composed of   high-cellularity   epithelial   neoplasia.   The   seminoma   was   classified   as spermatocytic, rarely reported in domestic and wild birds, and never described in seabirds. The neoplastic process led to extensive testicular destruction and caused functional impairment in one of the testicles, potentially resulting in reproductive capacity loss.
