    Melanocytic BAP-1-Mutated Atypical Intradermal Tumor in Two Siblings: A Case Report
    (2020) Kolbach-Rengifo, Marianne; Alfaro-Sepulveda, Daniela; Villarroel, Alejandra; Martin-Parada, Celeste; Gonzalez-Bombardiere, Sergio
    Melanocytic BAP-1-mutated atypical intradermal tumor (MBAIT) is a tumor that appears early on life. It can be the first manifestation of a tumor predisposition syndrome. Prompt diagnosis will allow for the implementation of early screening techniques for associated malignancies. We present a case of 2 siblings with MBAITs and their future management.

    Very High- and High-Frequency Ultrasound Features of Cutaneous Larva Migrans
    (2019) Ogueta, Isabel; Navajas-Galimany, Lucas; Concha-Rogazy, Marcela; Alvarez-Veliz, Sergio; Vera-Kellet, Cristian; Gonzalez-Bombardiere, Sergio; Wortsman, Ximena
    Cutaneous larva migrans is a common infestation among travelers. Although the diagnosis may be suspected clinically, cases can show atypical presentations. We present the ultrasound features of 4 cases at 18 and 70 MHz. Small linear hyperechoic and hyper-refringent subepidermal and intrafollicular structures suggestive of fragments of larvae, hypoechoic dermal and hypodermal tunnels that match with dilatation of lymphatic ducts, and inflammatory dermal and hypodermal ultrasound signs can support the diagnosis. This work suggests that larvae can penetrate the cutaneous basement membrane through the ostia of the hair follicles and potentially disseminate through the dermal and hypodermal lymphatic network.
