Mycobacterium abscessus (M. abscessus) is the second most common nontuberculous mycobacteria (NTM) in South Korea. Nevertheless, the diagnosis and treatment of M. abscessus lung disease can be problematic. Surgical resection has been tried for patients with localized M. abscessus lung disease refractory to medical treatment. Here, we report on a 25-year-old woman with M. abscessus lung disease who had been diagnosed and treated three times for pulmonary tuberculosis. She was initially diagnosed as having M. intracellulare lung disease; however, M. abscessus was isolated after several months of medication. She had multiple bronchiectatic and cavitary lesions bilaterally, and M. abscessus was repeatedly isolated from her sputa despite prolonged treatment with clarithromycin, ethambutol, moxifloxacin, and amikacin. She improved only after sequential bilateral lung resection. Based on the experience with this patient, we suggest that, if medical treatment fails, surgical resection of a diseased lung should be considered even in patients with bilateral lesions.

Mycobacterium celatum is a nontuberculous mycobacterium that rarely causes pulmonary disease in immunocompetent subjects. We describe the successful treatment of M. celatum lung disease with antimicobacterial chemotherapy and combined pulmonary resection. A 33-year-old woman was referred to our hospital with a 3-month history of a productive cough. Her medical history included pulmonary tuberculosis 14 years earlier. Her chest X-ray revealed a large cavitary lesion in the left upper lobe. The sputum smear was positive for acid-fast bacilli, and M. celatum was subsequently identified in more than three sputum cultures, using molecular methods. After 1 year of therapy with clarithromycin, ethambutol, and ciprofloxacin, the patient underwent a pulmonary resection for a persistent cavitary lesion. The patient was considered cured after receiving 12 months of postoperative antimycobacterial chemotherapy. There has been no recurrence of disease for 18 months after treatment completion. In summary, M. celatum is an infrequent cause of potentially treatable pulmonary disease in immunocompetent subjects. Patients with M. celatum pulmonary disease who can tolerate resectional surgery might be considered for surgery, especially in cases of persistent cavitary lesions despite antimycobacterial chemotherapy.

OBJECTIVETo clarify the clinical feature, diagnosis and therapy of the pulmonary cryptococcosis (PC).

METHODSA retrospective study of cases with PC who were diagnosed by pathological examinations between January 1996 and December 2010 was conducted. Eighty-one cases were enrolled in the study (58 male and 23 female patients; mean age of (51±11) years). Forty-one cases were asymptomatic at the time of diagnosis. There were single pulmonary lesions in 50 cases, and multiple lesions in 31 cases. Fourteen lesions (17.3%) were located in left upper lobe, 27 (33.3%) in left lower lobe, 21 (25.9%) in right upper lobe, 3 (3.7%) in right middle lobe, 28 (34.6%) in right lower lobe, and 3 (3.7%) diffusely involved bilateral lungs. The tumors ranged from 0.8 to 10.0 cm in diameter with a mean of (2.9±1.8) cm. All the cases were misdiagnosis prior to the surgical resection, and histologically confirmed by postoperative pathological specimens.

RESULTSAll the cases received surgical treatment including complete resection in 69 cases, and palliative resection in 12 cases. Resections were performed by means of video-assisted thoracoscopy in 31 cases and thoracotomy in 50 cases. Surgical resections included pulmonary wedge excisions in 42 cases, and lobectomies in 39 cases. After histological confirmation, 63 cases (77.8%) were treated with antifungal agents, which consisted of fluconazole in 38 cases, itraconazole in 18 cases, amphotericin B in 6 cases, and flucytosine in 4 cases. There were no intraoperative death, but two cases died for cryptococcal meningoencephalitis in the postoperative period. Operative morbidity occurred in 7 (8.6%) cases. The median follow-up was 42.5 months (6 to 84 months). There were 2 local relapses of PC, and 9 cases with complications of anti-fungal agents.

CONCLUSIONSThe clinical manifestations of PC are mild and non-specific, with no characteristic radiographic manifestations. Surgical resection is usually indicated for definite diagnosis and treatment. Antifungal drug therapy is indispensable even after complete resection.

To compare clinical features, diagnosis and therapeutic effect between pulmonary histoplasmosis and progressive disseminated histoplasmosis.
 Methods: A retrospective analysis for 12 cases of hospitalized patients with histoplasmosis, who was admitted in Xiangya Hospital, Central South University during the time from February 2009 to October 2015, was carried out. Four cases of pulmonary histoplasmosis and 8 cases of progressive disseminated histoplasmosis were included. The differences of clinical features, imaging tests, means for diagnosis and prognosis were analyzed between the two types of histoplasmosis.
 Results: The clinical manifestations of pulmonary histoplasmosis were mild, such as dry cough. However, the main clinical symptoms of progressive disseminated histoplasmosis were severe, including recurrence of high fever, superficial lymph node enlargement over the whole body, hepatosplenomegaly, accompanied by cough, abdominal pain, joint pain, skin changes, etc.Laboratory examination showed pancytopenia, abnormal liver function and abnormal coagulation function. One pulmonary case received the operation of left lower lung lobectomy, 3 cases of pulmonary histoplasmosis and 6 cases of progressive disseminated histoplasmosis patients were given deoxycholate amphotericin B, itraconazole, voriconazole or fluconazole for antifungal therapy. One disseminated case discharged from the hospital without treatment after diagnosis of histoplasmosis, and 1 disseminated case combined with severe pneumonia and active tuberculosis died ultimately.
 Conclusion: As a rare fungal infection, histoplasmosis is easily to be misdiagnosed. The diagnostic criteria depends on etiology through bone marrow smear and tissues biopsy. Liposomeal amphotericin B, deoxycholate amphotericin B and itraconazole are recommended to treat infection for histoplasma capsulatum.
