A Case of Diffuse Large B-Cell Lymphoma of Sinonasal Tract with Acute Visual Disturbance / 대한이비인후과학회지

Malignant lymphoma of the sinonasal tract is relatively uncommon. In particular, B-cell lymphoma is hardly found in the Asian population although the NK/T-cell type of lymphoma is relatively commonly found. The authors experienced a case of diffuse large B-cell lymphoma originating from the ethmoid sinus, which caused the unexpected visual disturbance without nasal symptoms and/or systemic B symptoms, such as fever, night sweat, and weight loss. Diagnosis of B cell lymphoma is often delayed because it does not always show the specific symptoms of lymphoma. Therefore, starting with careful physical and imaging studies are always important while higly suspecting malignancy. Furthermore, early precise biopsy is of great important for precise diagnosis and proper management for the treatment of malignant lymphoma.

A Case of Subcutaneous Hemangioma Presenting as a Preauricular Sinus

Hemangioma is one of the most common benign neoplasm involved on head and neck. However, cavernous hemangiomas are relatively rare in preauricular sinus space and has rarely been reported around the world. Recently, a 44-year-old female patient came to our clinic with cavernous hemangioma involving the preauricular sinus. This case was surgically managed via excision. Preoperatively, it was difficult to differentiate the mass of hemangioma clinically and diagnostically from a preauricular fistula, a salivary gland tumor, or an enchondroma. This case report describes the subcutaneous hemangioma on a preauricular sinus, which is rarely seen in Korea. The clinical presentation and management are discussed with a review of the literature.

Clinical Characteristics of Auricular Keloids Treated with Surgical Excision

BACKGROUND AND OBJECTIVES: Differences in morphology of auricular keloids possibly contribute to distinct results of treatment. The aim of this study was to evaluate clinical characteristics of the auricular keloids according to the modified Chang-Park classification and to compare the results of treatment including recurrence rate between the subgroups. SUBJECTS AND METHODS: Clinical data of 15 patients of auricular keloids were retrospectively reviewed. The keloids were classified according to modified Chang-Park classification. Clinical characteristics, the presence of recurrence, and the duration required for the recurrence were compared. RESULTS: Eight out of 15 patients (53.3%) were single sessile type (type II), followed by 4 patients of pedunculated type, 1 patient of multiple sessile type, 1 patient of buried type, and 1 patient of mixed type, respectively. Recurrent keloids after previous surgeries were noted in 7 out of 15 patients and most of them (6 of 7, 85.7%) were sessile type. Three patients who underwent surgery at our department showed recurrence. CONCLUSIONS: The classification of auricular keloids according to morphologic patterns can assist surgeons in choosing the appropriate management.
