RESUMO
INTRODUCTION: Parathyroid carcinoma is a very aggressive malignant tumor. It is mostly revealed by clinical primary hyperparathyroidism. CASE PRESENTATION: We report a rare case of parathyroid carcinoma in a 61-year-old-male patient who presented with a painless right-sided cervical tumefaction of hard consistency associated with cervical lymphadenopathy. Cervical ultrasonography showed a right parathyroid mass with intimate contact with the homolateral thyroid lobe. A parathyroidectomy enlarged to the adjacent thyroid parenchyma with a selective neck dissection level VI was performed. CLINICAL DISCUSSION: The clinical presentation is most often manifested with clinical features of primary hyperparathyroidism associating bone disorders. Surgery remains the treatment of choice. The benefit of adjuvant treatments is controversial and remains to be evaluated. CONCLUSION: Parathyroid carcinoma is a rare tumor. This rare entity is often presented with clinicobiological features of severe primary hyperparathyroidism.
RESUMO
INTRODUCTION: Cystic lymphangioma is a benign tumor originating from the lymph vessels. It commonly occurs in childhood, in the head or neck regions. However, abdominal Cystic lymphangioma is extremely rare in adult patients and often asymptomatic. Considering abdominal space, it may attain huge sizes whilst causing minimal symptoms. Due to this insidious presentation, these tumors become massive and can be diagnosed late at the complication stage. PRESENTATION OF CASE: This case report describes a rare and exceptional case of giant cystic lymphangioma of the stomach presented with a perforation in the abdominal cavity. The diagnosis was suspected following an abdominal CT scan, but could not confirm that the lesion was derived from the stomach. Therefore, an exploratory laparotomy found a multi-cystic mass occupying most of the abdominal space, adherent to the small gastric curvature and without delimitation line. This mass presents a small perforation responsible for an ascites of medium abundance. Then, the patient underwent a subtotal gastrectomy removing the entire cystic mass. Pathological analysis of the surgical specimen confirmed the diagnosis of cystic lymphangioma of the stomach.The postoperative recovery was uneventful, and the patient was discharged after 6 days. At the 3-month follow-up, the patient was in good health. DISCUSSION: The cystic lymphangioma of the stomach is rare and exceptionally described in the literature. However, if this tumor is benign, it has the potential to grow, invade vital structures, and develop life-threatening complications. CONCLUSION: We stress the importance of complete surgical excision to prevent cyst complications and to reduce the recurrence risk.
