Venous disease can manifest itself in unusual ways; three uncommon venous disease states are described, together with discussions of their treatment. The cases include an iliac compression syndrome, incipient venous gangrene of an upper limb associated with polycythemia and congestive cardiac failure, and venous edema of a lower limb as a sequel to previous radical pelvic surgery.
We report on the successful surgical resection of an aneurysm of the superior mesenteric artery. The saccular nature of the aneurysm and evidence of celiac axis occlusion in this patient posed an additional challenge in the successful surgical treatment.
Three patients with eosinophilic infiltration of the stomach and one with eosinophilic granulomatous polyp of the ileum are described. We believe that eosinophilic granulomatous lesions of the gastrointestinal tract comprise a distinct clinical and pathologic entity which should be considered in the differential diagnosis of obstructing or ulcerating lesions.
Papillary adenocarcinoma arising in a thyroglossal cyst is described in a 38-year-old man to make a total of 83 cases in the literature. Most cases appear to be benign thyroglossal duct cysts. The malignant nature of the lesion was recognized only after the permanent pathology sections were reviewed. Paillary carcinoma was the most common type of carcinoma arising in thyroglossal duct remnants. Local resection by the Sistrunk method is the standard treatment when the malignancy has not extended beyond the confines of the cyst. The differentiation between a carcinoma arising in a thyroglossal duct remnant and a metastatic papillary carcinoma from an occult primary in the main thyroid gland is discussed.
The incidence of hypoparathyroidism following thyroid surgery in the series reported was 7.8 per cent. Temporary hypoparathyroidism was present in 15 patients (4.6%) and permanent hypoparathyroidism in 10 (3.2%). Persistently low levels of serum calcium and high levels of serum phosphorus at six to 10 weeks after thyroid operation in patients with temporary hypoparathyroidism, with no tendency toward normalization, suggests permanent hypoparathyroidism. Serum calcium below 5 mg per cent suggests permanent hypoparathyroidism.
