Anaplastic carcinoma arising from median ectopic thyroid (thyroglossal duct remnant).

The first case of anaplastic carcinoma arising in median ectopic thyroid (thyroglossal duct remnants) in an 84-year-old woman is presented. This expands the spectrum of histologic types of thyroid malignancies reported in this location and supports the theory that these carcinomas arise from thyroid rests associated with thyroglossal ducts. The presence of a histologically benign follicular neoplasm adjacent to the carcinoma suggests the possibility that the anaplastic carcinoma resulted from the transformation of an underlying well-differentiated tumor. Some unusual features of this case are discussed as well as the criteria for establishing the diagnosis of carcinoma arising in a thyroglossal duct remnant.

Adult cystic hygroma.

Five adults with cystic hygromas underwent excisional surgery. The preoperative diagnosis is rarely made in adults; branchial cleft cyst is the most common preoperative impression. The histologic differentiation between these two lesions is described. Our experience indicates that surgery of cystic hygromas in the adult is not associated with the technical problems encountered in infants and children.

Fused inflammatory polyps simulating carcinoma in ulcerative colitis.

A 33-year old female with a 10-year history of ulcerative colitis developed a large polypoid filling defect in the distal transverse colon, suggestive of carcinoma of the colon. Biopsy indicated an inflammatory polyp but subtotal colectomy was performed because of the long history and the radiographic appearance. Pathologic examination revealed an unusual aggregation of filiform polyps entrapping a semisolid fecal mass. The development of this unique lesion is elaborated.
