Nasolabial cyst is a rare non-odonotogenic, soft-tissue, developmental cyst arising inferior to the nasoalar region of the face. The most common clinical finding of the nasolabial cyst is that of a slowly enlarging asymptomatic swelling typically without radiographic abnormalities. This case report describes a 25-year-old man in which the clinicopathologic findings and an erosive finding on the computed tomographic scan on maxilla were consistent with nasolabial cyst. The histopathologic features, differential diagnosis, treatment and prognosis are discussed.

Purpose: A nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst arising anywhere on the face inferior to the nasoalar region. It is thought to arise from either epithelial remnants trapped along the lines of fusion during the development of face or the remnants of the developing nasolacrimal duct. This study examines various features of nasolabial cysts with bony involvement to provide a basis for correct diagnosis and treatment. Methods: Eight cases of nasolabial cyst treated in Soonchunhyang Hospital between March 2002 and July 2010 were examined in terms of their clinical features and radiological and histological findings. Seven patients underwent surgical excision of the cyst via an intraoral, sublabial approach. One underwent incision and drainage. Results: Our eight patients were seven women and one man. The most frequent symptoms and signs were facial deformity and swelling of the nasolabial fold. Computed tomography (CT) showed a well-circumscribed cystic mass lateral to the pyriform aperture. Seven cases had erosive lesions on CT, and the intraoperative findings were consistent with a nasolabial cyst with a bony defect. Typical histopathological findings showed that these cysts were most frequently lined with respiratory epithelium with ciliated columnar cells and cuboid cells. No patient developed complications or recurrences. Conclusion: A nasolabial cyst is often unrecognized or confused with other intranasal masses, including fissural and odontogenic cysts, midface infections, or swelling in the nasolabial area. Therefore, a careful clinical and radiological evaluation should be preformed when considering the differential diagnosis. We present eight patients with nasolabial cysts treated via a gingivobuccal approach with excellent functional and cosmetic results.

Purpose To identify the imaging features indicative of sarcoid-like reactions in patients with intrathoracic lymphadenopathy after complete remission of malignancies. Materials and Methods This study enrolled five patients with histopathologically confirmed sarcoid-like reactions that developed after cancer remission. The clinical features and findings of CT and ¹⁸F-fluorodeoxyglucose (FDG) PET/CT were assessed. Results The underlying malignancies included breast, nasopharyngeal, colon, and endometrial cancer and lymphoma. The time intervals between complete remission of malignancy and the diagnosis of sarcoid-like reaction ranged from 6 to 78 months. CT findings of sarcoid-like reaction included bilateral hilar and mediastinal lymphadenopathies (n = 5), pulmonary nodules (1-15 mm) with peribronchovascular, fissural, or subpleural distribution, and interlobular interstitial thickening in the lungs (n = 4). ¹⁸F-FDG PET/CT revealed hypermetabolic uptake in the mediastinal and hilar lymph nodes and both lungs in the absence of extrathoracic uptake (n = 3). The sarcoid-like reactions resolved in all patients after corticosteroid treatment. Conclusion In patients with complete remission of malignancies, newly developed bilateral hilar and mediastinal lymphadenopathies with or without pulmonary nodules of perilymphatic distribution, in the absence of recurrence at the primary tumor site and extrathoracic metastasis, may suggest a sarcoid-like reaction. Such cases warrant histologic evaluation of the lymph nodes to prevent unnecessary systemic chemotherapy.
