Malignant tumors have been associated with the development of nephrotic syndrome. We report a 73-year-old man with nephrotic syndrome who had a malignant stromal gastric tumor. Curative resection of the sarcoma resulted in remission of the nephrotic syndrome.

Congenital thymic cysts are uncommon and often misdiagnosed as either branchial cleft or cystic hygromas. This paper presents the case of a male child, who presented with a soft, fluctuating mass in the left side of his neck. Surgical excision revealed an ectopic thymic cyst. The histopathologic features of thymic cysts are diagnostic. Ectopic thymic tissue may be an infrequent finding, but it should be included in the differential diagnosis of neck masses, especially in children.

INTRODUCTION: Parathyroid carcinoma is a rare tumor with an incidence of 0.5 to 4%. Preoperative differentiation from benign adenoma is very difficult. Several features, though nonspecific, have been used in differentiating parathyroid carcinoma from the adenoma. MATERIAL AND METHOD: A retrospective analysis during the period of nine years, four cases of parathyroid carcinoma were diagnosed on the basis of per-operative local invasion and on histological evidence of capsular invasion and vascular invasion. RESULT: We have different observations to make. Diagnosis of parathyroid carcinoma which was done on the basis of intra operative suspicion only. One patient died on 6th post operative day due to development of pancreatitis. At the follow-up of two years there was no local recurrence or distant metastasis. CONCLUSION: It is preferable to have a high index of suspicion for parathyroid carcinoma when these features are present than to miss the opportunity for surgical cure by failing to consider it in the differential diagnosis.
