In order to ascertain the role of TNF-alpha in pulmonary tuberculosis, we determined the TNF-alpha productivity of alveolar macrophages(AMs) obtained by bronchoalveolar lavage(BAL), along with the level of TNF-alpha in the serum of patients with tuberculosis including pulmonary, miliary, and endobronchial tuberculosis, healthy controls, and pulmonary diseases such as diffuse interstitial lung disease (DILD) and pneumonia. AMs from patients with pulmonary tuberculosis did not produce a larger amount of TNF-alpha than did those from the healthy control subjects. However, among the patients with pulmonary tuberculosis, the AMs from the fresh and reactivated groups produced a larger amount of TNF-alpha than those from the inactive group. AMs from patients showing positivity in culture produced a larger amount of TNF-alpha than those showing negativity. The average level of serum TNF-alpha in patients with pulmonary tuberculosis was slightly higher than that of the healthy control group. Among patients with pulmonary tuberculosis, significantly increased levels of serum TNF-alpha were noted in the reactivated group compared to those of the fresh and inactive group. Patients with moderate to far-advanced infiltration on their chest X-rays, showed a significantly higher level of serum TNF-alpha than those with minimal involvement on the chest X-ray. Smokers from the healthy control group showed a significantly higher level of serum TNF-alpha than non-smokers from the same group. These results suggest that an increase in the production of TNF-alpha may correspond with the severity of pulmonary tuberculosis.

Hemophagocytic lymphohistiocytosis (HLH) was a life-threatening syndrome due to the uncontrolled immune activation of cytotoxic T lymphocytes, natural killer (NK) cells, and macrophages. HLH is characterized by primary and secondary causes, the early diagnosis and treatment of patients are closely related to the prognosis and clinical outcome of patients. The clinical presentation is variable but mostly includes prolonged fever, splenomegaly, coagulopathy, hypertriglyceridemia, and hemophagocytosis, none of them is specific and particular for HLH. Tuberculosis (TB) infection is one of the causes of HLH. HLH caused by TB is very rare clinically, but it has a high mortality. For patients with fever of unknown origin, HLH-related clinical manifestations sometimes present before the final diagnosis of TB, and HLH is associated with the most significant mortality rate. This article is mainly about a 28-year-old patient with HLH who suffered from severe TB infection. The patient attended a hospital with a history of 2 months of prolonged fever, 10 days booger and subcutaneous hemorrhage in lower limbs. Before this, he was in good health and denied any history of tuberculosis exposure. Combined with relevant laboratory test results (such as splenomegaly, hemoglobin, platelet count, and hypertriglyceridemia) and clinical manifestations (e.g. fever), the patient was diagnosed with hemophagocytic lymphohistiocytosis, but the etiology of HLH remained to be determined. To confirm the etiology, the patient was asked about the relevant medical history (intermittent low back pain) and was performed chest CT scan, bone marrow biopsy, and fundus photography. Finally, he was diagnosed with hemophagocytic lymphohistiocytosis caused by hematogenous disseminated pulmonary tuberculosis. In response to this, intravenous methylprednisolone and anti-tuberculosis treatment (isoniazid, pyrazinamide, moxifloxacin, and amikacin) were administered to the patient. After more than a month of treatment, the patient recovered from HLH caused by severe TB infection. Therefore, this case suggests that we should be vigilant to the patient who admitted to the hospital with fever for unknown reasons, to diagnose HLH as early as possible and clarify its cause, then perform interventions and treatment, especially HLH secondary to tuberculosis. Also, cases of atypical TB and severe TB should be carefully monitored to achieve early diagnosis and early intervention.

Pulmonary lymphangioleiomyomatosis has been observed almost exclusively in women, usually in their reproductive years. Exacerbations with pregnancy and after hormonal manipulation have been documented, and it has been suggested that its pathogenesis is due to the influence of hormonal(estrogenic) stimulus. The clinical, roentgenographic, and histopathologic features of this case of pulmonary lymphangioleiomyomatosis in a 22-year-old male are all characteristic of those described in prior reports, except for the patient's sex. With the following case of pulmonary lymphangioleiomyomatosis in a male, we suggest the possibility of the existence of an additional pathogenetic mechanism.

Herein, we report a rare case of concurrent gastric and pulmonary mucosa-associated lymphoid tissue (MALT) lymphomas. A 65-year-old man who had been diagnosed with Helicobacter pylori-positive gastric MALT lymphoma received eradication therapy and achieved complete remission. During follow-up, he developed de novo pulmonary MALT lymphoma as a sequela of pulmonary tuberculosis, accompanied by recurrent gastric MALT lymphoma. Polymerase chain reaction (PCR) products of the CDR3 region of the immunoglobulin heavy chain gene showed an overall polyclonal pattern with bands at 400 base pairs (bp) and 200 bp predominant in the pulmonary tissue, as well as two distinctive bands in the gastric tissue at 400 bp and 200 bp. This case suggests that multiorgan lymphomas are more likely to be independent from each other when they are far apart, involve different organ systems, and have independent precipitating factors.
