A Case of Locally Invasive Thyroid Papillary Cancer Diagnosed by Esophagoscopy / 대한소화기내시경학회지

Papillary carcinoma is the most common malignant tumor of the thyroid gland, and it only infrequently invades the upper aerodigestive tract. When such invasion does occur, it is a source of significant morbidity as well as mortality. Although most thyroid tumors first clinically manifest as a neck mass, there have been few reports of patients whose initial compliant was a disturbance of the aerodigestive tract. The patient in our present study had no significant past medical history, and esophagoscopy and biopsy revealed papillary adenocarcinoma. We report here on a case of thyroid papillary carcinoma that was diagnosed by esophagoscopic biopsy.

A Case of Advanced Gastric Cancer and the First Symptom was a Skin Lesion / 대한소화기내시경학회지

Cutaneous metastasis of internal malignancies is rare and the incidence of metastatic skin lesions as the first symptom of disease is only 0.8% for patients with all types of malignancies. Furthermore, cutaneous metastasis from advanced gastric cancer is exceedingly rare. A 43-year-old man presented with a single, symptomatic, erythematous nodule on the chest wall. A biopsy taken from the nodule showed an adenocarcinoma of the poorly differentiated type. An endoscopic examination and biopsy was done and these showed the same histologic findings. We reported here on this unusual case of advanced gastric cancer and the patient's first symptom was a skin lesion.
