Endoscopic ultrasound in the diagnosis of foreign bodies of the colon and rectum / Ultrassonografia endoscópica no diagnóstico de corpos estranhos no cólon e no reto

SUMMARY Although the ingestion of foreign bodies is a common clinical problem, severe complications such as perforation are rare and occur in less than 1% of cases. Different types of foreign bodies and the various affected regions within the gastrointestinal tract make foreign body ingestion a complex entity, with a wide range of presentation requiring different diagnostic modalities. We report two cases of patients who underwent endoscopic ultrasound for evaluation of sub-epithelial lesions consisting of foreign body granulomas in the colon and rectum. Colorectal foreign body granuloma is a rare complication after accidental ingestion. Endoscopic ultrasound can be a useful diagnostic tool and can avoid the need for more invasive procedures.

RESUMO Embora a ingestão de corpos estranhos seja uma condição clínica frequente, complicações graves como perfuração são raras e ocorrem em menos de 1% dos casos. Tipos diferentes de corpos estranhos e as diversas regiões afetadas do trato gastrointestinal fazem da ingestão de corpos estranhos uma entidade complexa, com uma variada gama de apresentações, demandando várias modalidades diagnósticas. Nós reportamos dois casos de pacientes que foram submetidos à ultrassonografia endoscópica para avaliação de lesões subepiteliais, consistindo em granulomas de corpo estranho no cólon e no reto. Granulomas de corpo estranho colorretais são uma complicação rara após ingestão acidental. Ultrassonografia endoscópica pode ser uma ferramenta diagnóstica útil e pode evitar procedimentos mais invasivos.

Periorbital Lipogranuloma after Facial Autologous Fat Injection and Its Treatment Outcomes

PURPOSE: To investigate periorbital lipogranuloma cases that developed after autologous fat injection and to determine various treatment outcomes from these cases. METHODS: This retrospective study involved 27 patients who presented with periocular mass (final diagnosis of lipogranuloma) and had history of facial autologous fat injection. The collected data included information on patient sex, age, clinical presentation, number and site of fat injections, interval between injections, duration from injection to symptom onset, fat harvesting site, use of cryopreservation, and treatment outcome. RESULTS: The most common presenting symptom was palpable mass (92.6%), followed by blepharoptosis and eyelid edema. The mean time from injection to symptom onset was 13.6 +/- 29.2 months (range, 2 to 153 months). Patients were managed by intralesional triamcinolone injection (six patients) and surgical excision (three patients); 18 patients were followed without treatment. Among the six patients who underwent intralesional triamcinolone injection, five showed complete resolution, and one showed partial resolution. Among the 18 patients who were followed without management, three showed spontaneous resolution over a 5-month follow-up period. CONCLUSIONS: Lipogranuloma can develop in the eyelid after autologous fat injection into the face. Both surgical excision and intralesional triamcinolone injection yield relatively good outcomes. Simple observation can be a good option because spontaneous resolution can occur in a subset of patients.

Foreign Body Granuloma Masquerading as Bladder Tumor: A Rare Case Report.

Foreign body granuloma can occur after any surgical procedure, where non absorbable sutures have been used. It may occur due to forgotten other non-absorbable like gauze. Though foreign body granuloma has been reported involving many organs, but it is very rare to involve urinary bladder wall and to present it as urinary bladder tumor. We present such a unique case where use of Barbour thread for tubal ligation led to a large foreign body granuloma infiltrating bladder wall and presenting as bladder mass. Even contrast enhanced computed tomography showed a mass, which appeared to arise from the anterior aspect of the bladder suggestive of urachal carcinoma. Only on histopathological examination diagnosis was confirmed to be foreign body granuloma.
