Quiste pilonidal del ombligo: Presentación de dos casos

Introduction: Umbilical pilonidal sinus (UPS) is a rare condition and is therefore not detected early. The aim of this document is to discuss this pathology. Case report: We present two patients referred due to an inflammatory process of the navel, with the presence of a malodor. The first patient, after two months of unsuccessful local treatment, was intervened by a resection of the umbilical lesion, verifying hair content in the sinus. In the second patient the diagnosis was evident during anamnesis and confirmed with the physical examination. In both cases, a partial resection of the umbilicus was performed, including the pilonidal sinus. Biopsy confirmed the diagnosis. The postoperative result has been satisfactory, without relapse. Discussion and Conclusion: There are not much literature related to UPS. Conservative treatment or surgical resection of the sinus is proposed. In our limited experience we proceeded to a surgical resection of the lesion and recommend eliminating the hairs of the periumbilical region. We cannot rule out the conservative management option in future cases, before proposing surgery.
