IntroductionLipomas of the gastrointestinal tract are a rare condition. Only 5% are of gastric origin, and this corresponds to 2% to 3% of all benign tumors of the stomach and less than 1% of all gastric neoplasms. It is our purpose to report an unusual presentation of a giant gastric lipoma in an oligosymptomatic patient and highlight the importance of discussing differential diagnosis in this situation. A review of the literature has shown that this is one of the largest gastric lipomas described.Case presentationWe describe a rare case of a benign gastric tumor with uncommon features in a 63-year-old Caucasian woman. She was admitted with abdominal discomfort, nausea, and upper abdominal fullness after eating. The lesion was suspicious of malignancy because of its dimension and central contrast enhancement on computed tomography. Conventional upper digestive endoscopy revealed a large bulging mass in the gastric posterior wall and three ulcerated areas. In this procedure, a technical limitation due to the location of the mass in the submucosa prevented an adequate biopsy from being obtained. The fragments obtained from the ulcers revealed nothing but necrotic mucosa. Our patient underwent a subtotal gastrectomy and D1 lymphadenectomy with a Roux-en-Y reconstruction. Macroscopic findings revealed a 12 × 8 × 6cm mass with a volume of 576cm3, and the histological pattern demonstrated well-differentiated mature adipose tissue surrounded by a fibrous capsule, confirming the diagnosis of gastric submucosal lipoma.ConclusionsGastric lipoma is a rare benign disease that eventually simulates a malignant tumor.

Patient: Female, 65Final Diagnosis: Clavicle Kirschner wire migration into left lungSymptoms: No symptomsMedication: —Clinical Procedure: ThoracotomySpecialty: SurgeryObjective:Diagnostic/therapeutic accidentsBackground:Kirschner wires are often used to perform osteosynthesis. Migration through tissue of these wires is a rare but well-known occurrence.Case Report:A 65-year-old female presented with light intensity pain complaints in the upper left chest area; personal history included left clavicle fracture 20 years ago that was treated surgically with fixation using a K-wire. Chest radiography showed the presence of metallic foreign body in the left pulmonary apex. An exploratory axillary thoracotomy was performed, and the foreign body was extracted by a pneumotomy.Conclusions:To obtain satisfactory results with a K-wire, some peculiarities in their application should be respected. The time from orthopedic surgery of the collarbone to migration into the chest of the metal rod used can vary from one day to nearly 20 years. Although the migration mechanism remains unclear, it is likely that it involves shoulder movements, breathing movements, negative intrathoracic pressure, gravitational force, or local bone resorption. Caution should be exercised when orthopedic pins and wires are used for the fixation of fractures and dislocations of the shoulder girdle. If there is migration of the wire, it should be removed immediately to avoid sudden and fatal complications.

BackgroundWe herein present a case in which a Toxoplasma cyst was found in a transbronchial biopsy specimen from an immunocompetent patient with negative serology for the parasite.Case presentationAn 18-year-old Brazilian man presented with a 1-week history of dyspnea and fever and was diagnosed with right lower lobe pneumonia. He began inpatient treatment with intravenous antibiotics. During treatment, a bronchoscopy with bronchoalveolar lavage and transbronchial biopsy was performed. Anatomopathological examination of the transbronchial biopsy showed a small fragment of lung parenchyma with discrete septal thickening and a rounded structure, suggestive of a pseudocyst containing Toxoplasma gondii bradyzoites. However, serological tests were negative for immunoglobulin G and immunoglobulin M.ConclusionsBronchoscopy is a minimally invasive, effective diagnostic and therapeutic method. Despite the fact that the Toxoplasma pseudocyst in the present case was not the cause of the patient’s comorbidities, bronchoscopy with transbronchial biopsy allowed for an incidental diagnosis of a Toxoplasma pseudocyst with minimal invasiveness.
