- Abdominal Actinomycosis misdiagnosed as liposarcomaPublication . Vieira E Monteiro, Eunice; Gaspar, Joana; Paiva, Cláudia; Correia, Raquel; Valente, Vítor; Coelho, André; Lamas, Nuno JorgeActinomycosis is an uncommon, endogenous, and chronic infection with varied and nonspecific clinical features such as abdominal, pelvic or cervical masses, ulcerative lesions, abscesses, draining fistula, fibrosis, and constitutional symptoms. The disease ensues when the bacteria disrupt the mucosal barrier, invade, and spread throughout interfascial planes. Currently, the diagnosis of actinomycosis is challenging because of its very low frequency and depending on the clinical presentation it may masquerade malignancies. Therapy consists initially in intravenous penicillin, followed by an oral regimen that may be extended until a year of treatment. A timely diagnosis is crucial to avoid extensive therapeutic attempt as surgery. However, a biopsy or drainage of abscesses and fistula's tract may be required not only as a diagnostic procedure as part of the therapy. We report the case of a 72-year-old woman with an abdominal mass initially misdiagnosed as a liposarcoma. A second biopsy of a skin lesion of the abdominal wall made the diagnosis of actinomycosis, avoiding a major surgical procedure. The patient was treated with a long-term course of antibiotics with favorable outcome. Liposarcoma was ruled out after the patient's full recovery with antibiotics and the misdiagnosis was credit to the overconfidence on the immunohistochemical positivity to MDM2.
- Laparoscopic treatment of a gastro-gastric fistula after Roux-en-Y gastric bypass—report of two casesPublication . Gaspar, Joana; Marques, Paula; Mesquita, Isabel; Marcos, Mário; Santos, Jorge; Nogueira, CarlosThe most frequently performed bariatric surgery is the laparoscopic Roux-en-Y gastric bypass (LRYGB). An uncommon complication of LRYGB is gastro-gastric fistula (GGF). Possible causes of GGF include incomplete transection of the stomach during the initial surgery, staple-line leaks in the post-operative period and marginal ulcers. The optimal management of GGF is still under debate, with medical, endoscopic and surgical treatment modalities available. The authors present two cases of a GGF successfully managed with a laparoscopic surgical approach, after failed medical and endoscopic treatment.
- Unilateral renal agenesis and uterine anomalies: how and when can we make this diagnosis?Publication . Gaspar, Joana; Ferreira, Natália; Lobo, Luísa; Simão, CarlaA 12-year-old female with a prenatal diagnosis of left kidney agenesis was hospitalized with a history of four months of recurrent abdominal pain and dysmenorrhea after menarche. Imaging investigation revealed a gynecological malformation associated with Müllerian developmental defects – duplicated uterus with an obstructed left hemi-uterus filled with hematic content (haematometra), one cervix and a normal vagina. We pretend to alert pediatric physicians about the association of renal agenesis and gynecological malformations, most frequently uterine, but also vaginal. Early detection of these malformations by imaging will anticipate therapeutic measures to relieve symptoms, mostly recurrent abdominal or pelvic pain, and to avoid complications such as endometriosis, pelvic adherences and infections.
