Potts puffy tumor is a subperiosteal abscess of the frontal bone associated with the underlying frontal osteomyelitis. It has become a rare disease entity due to the development of antibiotics. Despite its rarity, it must be managed carefully because it is often associated with significant intracranial complications. We described a 12-year-old girl with Potts puffy tumor accompanied with epidural abscess and subdural empyema, which was considered to be caused by the contralateral frontal sinusitis. To our knowledge, a Potts puffy tumor caused by contralateral frontal sinusitis has not been reported in the literature. We discuss the clinical presentation and successful treatment of this unique case with brief review of the literature. (Korean J Otolaryngol 2006;49: 109-12)
primarily in patients with acute myelogenous leukemia (AML). The gra-nulocytic sarcoma can arise before, concurrent with, or following acute myeloid leukemia. This tumor can be rarely represented as the initial presentation of acute myeloid leukemia without any signs or symptoms of leukemia. Granulocytic sarcoma, rarely, can also occur in unexpected regions, including the head and neck. This tumor is very often misdiagnosed as a malignant lymph-oma which leads to inappropriate treatment and poor outcome. Therefore, clinical, histopathological and immumohistochemical findings should be evaluated before any diagnosis of malignant lymphoma. We report, with a brief review of literature, a case of granulocytic sarcoma presenting as a head and neck neoplasm. (Korean J Otolaryngol 2007 ;50 :362-5)
Primary cutaneous adenosquamous carcinomas are very rare with only few published reports. The histopathologic finding consists of two different components - mucin secreting cells (adenocarcinoma) and squamous cells (squamous cell carcinoma). We experienced a case of occipital scalp adenosquamous carcinoma, which is an extremely rare neoplasm in scalp. The lesion is histologically distinctive because of the presence of mixed areas of unequivocal adenocarcinoma and squamous cell carcinoma. It is found that combined surgery and additional radiation therapy is necessary because the biological behavior and prognosis of this neoplasm are considered as more aggressive and worse than that of conventional squamous cell carcinoma.
Primary Ewing sarcoma (ES) arising in the head and neck region is extremely rare, comprising only 1-4% of all cases of ES. ES is much more common in children and white populations,and has a slightly male predominance. About a quarter of patients have detectable metastases at diagnosis. The lung is the most common site for metastases (50%), followed by bone (25%)and bone marrow (20%). We report a case of 27-year-old woman who presented with cervical Ewing sarcoma with lung metastasis and was treated with surgery and chemotherapy.

Primary hyperparathyroidism with concomitant thyroid disease is common. However, the simultaneous occurrence of parathyroid adenoma and thyroid cancer is rare. We report a 55-year-old man with primary hyperparathyroidism who presented with chest tightness. In this patient, preoperative imaging studies for diagnosis revealed the presence of nodules in right parathyroid gland and left inferior pole of thyroid gland. However, Tc-MIBI scintigraphy did not localize parathyroid lesion. We performed technique of intraoperative methylene blue infusion for localization of parathyroid. The right parathyroid lesion was easily detected and right parathyroidectomy was performed successfully. After parathyroidectomy, the left thyroid lesion was confirmed to papillary carcinoma by frozen biopsy. The patient consecutively underwent total thyroidectomy. Pathology revealed parathyroid adenoma with concurrent papillary thyroid carcinoma. The coexistence of parathyroid adenoma and thyroid malignancy was possible for all patients in primary hyperparathyroidism with thyroid nodules. Therefore, careful thyroid evaluation must be necessary for all patients with primary hyperparathyroidism. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:566-9)
Primary laryngeal aspergillosis is exceptionally rare, and only nineteen cases have been reported in the literature. It is more comonly sen as a part of a wider infection involving the respiratory system in an imunocompromised host. We present here one case of primary laryngeal aspergillosis without any other airway tract extension and without any generalized imune deficit in a 58-year-old man. Direct laryngoscopy and biopsy confirmed the diagnosis of aspergillosis. (Korean J Otolaryngol 2002; 45:422-4)
Primary malignant lymphomas of the salivary glands are uncommon. The parotid gland was most frequently involved, followed by the submandibular gland, minor salivary glands and sublingual gland. The most common subtype is mucosa-associated lymphoid tissue (MALT) lymphoma. MALT lymphoma is a relatively indolent disease and tends to remain localized for prolonged period of time. But, we experienced a case of a multifocal salivary MALT lymphoma involving both parotid glands and right submandibular gland during its progression of disease. We report a case with a review of the literature. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:1166-9)
