 Abstract
 PDF
- Gangliocytic paraganglioma (GP) is a rare benign tumor that is usually seen in the duodenum. It shows unique histologic features that are composed of a carcinoid or paraganglioma-like appearance, ganglion cells, and Schwann cells. The common presenting symptoms are abdominal pain, gastrointestinal bleeding and obstruction. The lesion can sometimes be asymptomatic and they are discovered incidentally. We experienced a case of incidentally found GP in a 73 year-old-man who had a colon cancer with liver metastasis. During the preoperative workup, a submucosal tumor was found in the duodenal papilla. The frozen diagnosis of the duodenal mass was GP, which was confirmed by the permanent sections and immunohistochemical staining.
Pathologists should be alert to recognize and diagnose this rare, but benign disease, especially in the patient suffering with gastrointestinal cancer.

Abstract
PDF
- Fibromatosis colli is a benign fibrous tissue proliferation of sternocleidomastoid muscle, which is usually observed during the first month of life, often associated with congenital torticollis. It should be differentiated from other neck masses in infants because the usual initial treatment of fibromatosis colli is conservative management and invasive therapy should be avoided. Fine needle aspiration cytology provides an excellent minimally invasive diagnostic way for evaluation of infantile neck masses. We describe three cases of fibromatosis colli diagnosed by fine needle aspiration cytology. All of them were younger than one month and presented as a neck mass. Clinical impressions were malignant tumors in two cases and fibromatosis colli in one case. Fine needle aspiration cytology revealed benign and mature fibroblasts and atrophic striated muscle fibers.
The cytologic diagnosis was fibromatosis colli or benign fibous lesion.
