We report a bronchopulmonary infection with Mycobacterium malmoense in a patient with severe immunosuppression due to insulin-dependent diabetes mellitus, humoral immunodeficiency after thymoma (Good's syndrome) and prolonged immunosuppressive treatment after myasthenic crisis. It presented as non-resolving pneumonia of the left lower lobe. Bronchoscopically, a bronchoesophageal fistula was detected. Numerous acid-fast organisms were found in the sputum specimen and in the bronchial biopsy around the fistula. M. malmoense was isolated from sputum, bronchoalveolar lavage and bronchial biopsy. Whereas conventional in vitro susceptibility testing revealed susceptibility only to ethambutol, multi-drug susceptibility testing confirmed susceptibility to rifampicin, ethambutol, clarithromycin and prothionamide. The clinical outcome after 12 months of therapy resulted in a stable remission and considerable suppression of the mycobacterial load, but not in complete eradication.

A 61-year-old woman who had undergone an operation for thymoma 17 years previously suddenly became dyspneic and showed bilateral pulmonary infiltrates on a chest radiograph. In the bronchoalveolar lavage fluid cells contained characteristic cytomegalic inclusion bodies, as well as cytomegalovirus DNA demonstrated by a polymerase chain reaction. Immunological findings included hypogammaglobulinemia, deficient numbers of circulating B cells, and impaired blast transformation of peripheral blood T cells in response to mitogens in vitro. Considering all of the findings, the patient was diagnosed with Good's syndrome presenting with cytomegalovirus pneumonia.

Immunodeficiency with thymoma (Good syndrome, GS) is a rare, adult-onset condition that is characterized by thymoma, hypogammaglobulinemia, and low numbers of peripheral B cells. CD4+ T lymphopenia and an inverted CD4:CD8+ T-cell ratio may be present. Here we report 5 patients with GS and infectious complications who were seen at 3 institutions between 1983 and 1999. Three patients had recurrent sinopulmonary infections, 3 had severe cytomegalovirus (CMV) disease, and 1 had Pneumocystis carinii pneumonia. Review of the literature identified 46 other reports of infections in GS patients. The infections reported in all 51 patients included recurrent sinopulmonary infection (19 cases with documented respiratory pathogens), generally with encapsulated bacteria, most often Haemophilus influenzae (11 cases); CMV disease (5 cases); bacteremia (7 cases); oral or esophageal candidiasis (6 cases); persistent mucocutaneous candidiasis (5 cases); chronic diarrhea (5 cases with documented stool pathogens); urinary tract infections (4 cases); P. carinii pneumonia (3 cases); tuberculosis (2 cases); Kaposi sarcoma (1 case); disseminated varicella (1 case); candidemia (1 case); wound infection with Clostridium perfringens (1 case); Mycoplasma arthritis (1 case); and other infections. Patients with GS present with a spectrum of sinopulmonary infections and pathogens similar to common variable immunodeficiency (CVID). Compared with patients with CVID, opportunistic infections, including severe CMV disease, P. carinii pneumonia, and mucocutaneous candidiasis, appear to be more common in patients with GS, and patients with GS may have a worse prognosis. GS should be ruled out in patients with thymoma or CVID who develop severe, especially opportunistic, infections. Treatment with intravenous immune globulin is recommended for all patients with GS.

Good's syndrome is extremely rare and refers to an acquired B and T cell immunodeficiency in thymoma patients. We report a 51-year-old female thymoma patient who presented with recurrent herpes zoster, pneumonia, diarrhea and opportunistic infections. She was found to have acquired hypogammaglobulinemia with absent B cells. Despite repeat intravenous immunoglobulin replacement and antibiotic therapy, she died of bacterial pneumonia-induced acute respiratory distress syndrome. Clinicians should look for evidence of immunologic dysfunction in thymoma patients presenting with recurrent infections.

Thymomas are neoplasias that begin in the thymus and develop in the anterior mediastinum. They are commonly associated with a variety of systemic and autoimmune disorders, such as pure red cell aplasia, hypogammaglobulinaemia, pancytopaenia, collagen diseases, and, most commonly, myasthenia gravis. The presence of inter-current infections, especially diarrhoea and pneumonia, in the presence of lymphocyte B depletion and hypogammaglobulinaemia is known as Good's syndrome and may affect up to 5% of patients with thymoma. While anaemia is present in 50%-86% of patients with Good's syndrome, only 41.9% of cases present pure red cell aplasia. Concomitance of these two conditions has only been rarely studied. We report on the case of a 55-year-old man diagnosed with advanced thymoma, who, during the progression of his disease, developed signs and symptoms suggesting Good's syndrome and pure red cell aplasia. We also performed a brief review of the literature concerning this association, its clinical characteristics, and treatment.

Good's syndrome (GS) is a rare combination of thymoma and hypogammaglobulinemia, resulting in immunodeficiency. Patients with GS are highly susceptible to bacterial infection, particularly encapsulated bacterial infection in upper and lower respiratory tracts. Good's syndrome patients with moderate-to- severe infection are often hospitalized. Clinical features of GS patients remain to be characterized.Patients with the discharge diagnosis of GS and simultaneous infection from Peking Union Medical College Hospital between January 2001 and July 2015 were retrospectively analyzed.Among 14 hospitalized GS patients, 12 of them were admitted for severe infections. Mean patient age was 56.7 + 10.1 years. Average concentrations of serum IgG, IgA, and IgM were 2.3 + 1.9 g/L, 0.28 + 0.28 g/L, and 0.06 + 0.07 g/L, respectively. Respiratory and intestinal tracts were the most common sites for infection, which occurred in 7 and 4 patients, respectively. Pathogens identified in 10 patients included cytomegalovirus in 5 patients, Pneumocystis jirovecii, Clostridium difficile in 2 patients, Klebsiella pneumonia in 2 patients, and Streptococcus pneumonia and Hemophilus influenza in 1 patient. Ten patients were treated with antibiotics and immunoglobulin replacement. Only 1 patient who was on immunosuppressant therapy died from P. jirovecii pneumonia.Infection was the most frequent cause for hospitalization of GS patients. Both respiratory and intestinal tracts were the most common sites of infection. Cytomegalovirus and P. jirovecii represented 2 common opportunistic pathogens isolated from hospitalized GS patients with infections.

Adult onset immunodeficiency associated with thymoma is a rare condition. The combination of hypogammaglobulinemia, reduced number of peripheral B and CD4+ T cells, along with thymoma constitutes Good's syndrome (GS). This immunodeficiency condition is often complicated with opportunistic infection with organisms, like bacteria (Haemophilus influenzae, Streptococcus pneumonia etc), viruses (Cytomegalovirus, Herpes simplex etc), fungi and protozoa. We present an unusual case of Good's syndrome with pulmonary tuberculosis (PTB). A 40-year-old man presented with sputum-positive PTB and was started on anti-tuberculosis treatment. Subsequently, he developed symptoms and findings consistent with thymoma and other components of Good's syndrome. Although patients of Good's syndrome are susceptible to various opportunistic infections, infection with Mycobacterium tuberculosis is uncommon. Evidence of recurrent infections or some opportunistic infection in a thymoma patient should trigger a suspicion of Good's syndrome.

Good's syndrome is a rare condition of immunodeficiency that is characterized by thymoma and hypogammaglobulinemia. A 74-year-old Japanese woman underwent total thymothymectomy for type AB thymoma (2015 WHO classification). She developed recurrent infectious diseases caused by Escherichia coli (bacteremia), Streptococcus pneumoniae (pneumonia and bacteremia) and Pseudomonas aeruginosa (bacteremia) in the year after thymectomy. The serum levels of immunoglobulin were significantly low (IgG 157mg/dL), which suggested that her infectious diseases were associated with Good's syndrome. Although she began receiving intravenous immunoglobulin every four weeks, she died of pneumonia a week after the second administration of immunoglobulin. When physicians encounter patients with recurrent infection who have a medical history of thymoma, the detection of hypogammaglubulinemia can be a key clue to the diagnosis of Good's syndrome.

Bordetella bronchiseptica infection is a common cause of pneumonia in animals but rarely causes disease in humans. Additionally, coinfection with Pneumocystis jirovecii is very uncommon and is occasionally seen in patients with acquired immunodeficiency syndrome (AIDS). We report a case of a 61-year-old HIV-negative man, who presented with hypoxic respiratory failure 2 days after completion of systemic intravenous antibiotic treatment for B bronchiseptica. His past medical history was significant for a benign thymoma. The patient was found to be coinfected with B bronchiseptica and P jirovecii. Laboratory results showed panhypogammaglobulinemia and low absolute B- and CD4 T-cells. Therefore, the patient was diagnosed with Good's syndrome. However, despite treatment with intravenous antibiotics and intravenous immunoglobulin, the patient continued to deteriorate and expired. This patient demonstrates the importance of recognizing this rare immunodeficiency early in order to improve morbidity and mortality. Furthermore, this case highlights the importance of early immunoglobulin screening in the presence of asymptomatic thymoma.

The Good's syndrome (GS) is a low prevalence entity where thymoma often is associated with immunodeficiency. Patients may start presenting recurrent rhinosinusal infections, bronchopulmonary infections, haematological alterations and diarrhoea, secondary to immunodeficiency. They can also present respiratory symptoms and parathymic syndromes derived from the existence of thymoma, a slow-growing neoplasm located in the anterior mediastinum. We present the case of a 76-year-old man diagnosed with thymoma by image analysis, which had presented multiple episodes of pneumonia and two admissions to the hospital for diarrhoea of weeks of evolution. After finishing the study, the patient is diagnosed of GS. In this case, thymectomy prevented the appearance of parathymic syndrome, but without any effect on immunodeficiency symptoms. To decrease repeat infections, substitution therapy with immunoglobulins was started. The prognosis will depend mainly on the recurrent infectious and to a lesser extent on the thymic neoplasm.
