Sarcoidosis*

Summary Sarcoidosis is a multisystem disease characterised by granulomatous inflammation possibly due to hyperactivation of the immune system; with unknown etiology. Subcutaneous sarcoidosis (also known as Darier Roussy sarcoid) is a rare type of specific cutaneous lesion of sarcoidosis characterised by multiple firm, asymptomatic to mildly tender, mobile, round to oval, and skin coloured nodules. Herein we report a rare case of subcutaneous sarcoidosis.
Sarcoidosis

Sarcoidosis is a multisystemic disorder of unknown cause that is characterized pathologically by noncaseating granulomas. Diagnosis is based on the exclusion of other infectious, interstitial, and neoplastic diseases and on the typical pathology. Although the lungs and mediastinal lymph nodes are almost involved, endobronchial nodular lesions of sarcoidosis with lung involvements are rare. We report a case of sarcoidosis with lung involvements and endobronchial nodules as confirmed by bronchial biopsy.

Interferon alpha is an immunomodulator that is used as an antiviral agent to treat chronic active viral hepatitis C. However, interferon can induce or exacerbate sarcoidosis. We report a case of 42-year-old man with an exacerbation of pulmonary sarcoidosis after the cessation of interferon and ribavirin therapy for chronic hepatitis C. The patient's sarcoidosis improved spontaneously and he continues to be monitored regularly without steroid therapy.

A unique case of atypical pulmonary sarcoidosis in a 62-year-old man complaining of dyspnea is presented. Chest CT scan showed an unusual pattern and distribution of pulmonary sarcoidosis manifesting mainly as reticular densities, interlobular septal thickening, and ground-glass opacities, in the subpleural and lower lung predominancy. However, a surgical lung biopsy revealed classical findings of sarcoidosis. Knowledge of this atypical pulmonary involvement may improve understanding sarcoidosis as the great masquerader.

PURPOSE: To analyse the radiographic and HRCT findings of pulmonary sarcoidosis and to evaluate thediagnostic usefulness of HRCT MATERIALS AND METHODS: Initial chest radiographs (n=14) and HRCT scans (n=14), anda followup HRCT scan (n=1) from 14 patients (5 men and 9 women;median age, 38 Years) with biopsy proven pulmonarysarcoidosis were analyzed. RESULT: On initial chest radiographs, they showed pulmonary lesions were seenpredominantly in the middle, upper and lower lung zones in four, two and one patient, respectively. Patterns oflesions were reticulonodular opacities (n=4), air-space (n=2), honeycombing(n=1), macronodule(n=1), and cavitarynodule (n=1). In all patients, HRCT scans demonstrated both pulmonary lesions and intrathoracic lymphadenopathy.Pulmonary lesions were seen predominantly in the middle, lower and upper lung zones in nine, three and twopatients, and in the posterior and anterior lung zones in eight and four patients repectively. Lesions werepredominantly micronodules, with perilymphatic distribution (n=12), macronodules with air-bronchogram (n=1),cavitary macronodules (n=1), ground-glass opacity (n=5), consolidation (n=2), and irregular lines (n=8). CONCLUSION: Reticulonodular lesions in the middle lung zone were seen on radiograph, while the most common HRCTfinding was micronodular lesions with perilymhpatic distribution. HRCT is much more sensitive than chestradiograph for the detection of both pulmonary lesions and lymphadenopathy; this modality revealed micronoduleswhich were invisible on chest radiographs.

Sarcoidosis is a rare multisystemic granulomatous disease. The lungs, lymph nodes, eyes, skin and liver are the most commonly involved. There are two distinct forms of sarcoidosis in children. One is early-onset(younger) childhood sarcoidosis characterized by skin rash, uveitis, and arthritis occurring before age 4 years. The other is late-onset(older) childhood sarcoidosis characterized by involvement of the lungs, the common radiographic finding is bilateral hilar lymph node enlargements, similar to the adult manifestation. We report a case of late-onset childhood sarcoidosis in a 6-year-old girl which is the first pediatric pulmonary sarcoidosis reported in Korea.
