RESUMO
Overall gastric cancer incidence is decreasing, but incidence of gastric signet ring cell carcinoma has been rising. The diagnosis can be challenging. It has a poorer prognosis because it tends to be diagnosed at advanced stages. Lymphedema is a rare presentation. We report a rare presentation of signet ring cell carcinoma in a 49-year old male, with no underlying medical condition. The patient presented with lymphedema of lower limbs, scrotum and abdominal wall. LEARNING POINTS: Signet ring cell carcinoma tends to have an infiltrative behavior. Endoscopic analysis may not lead to any macroscopic finding.In highly suspicious cases, endoscopic exploration should be complemented with an endoscopic ultrasound or blind random biopsies.
RESUMO
Glomus tumour is a rare benign mesenchymal neoplasm usually located in the dermis and subcutis, and most commonly found in the extremities. Glomus tumour in the gastrointestinal system is rare and its symptoms unspecific. The diagnosis of gastric glomus tumour is challenging due to the lack of specific findings on imaging and blood analysis, and so is usually based on histology and immunochemistry. We describe the case of a 22-year-old man admitted for pallor and anaemia, the diagnostic path, treatment and follow-up. The present case suggests that this rare entity should be considered in the differential diagnosis of gastric lesions. LEARNING POINTS: Glomus tumour is a rare benign mesenchymal neoplasm most commonly found in the extremities.Gastric glomus tumour (GGT) is rare and its symptoms unspecific.The diagnosis of GGT relies on histology and immunohistochemistry as imaging lacks accuracy.Treatment is usually surgical but follow-up should be considered due to its malignant potential.
